Wine makers fall into three broad and ill defined categories:
Traditional wine makers: who grow their grapes and maintain them without using organic or bio-dynamic techniques. They work to improve the yield of the grapes by trellising the vines, weeding them and using pesticides. Where economical they use machinery to tend the grapes and harvest them. Some farmers sell their grapes to a co-operative which produces the wine, whilst others produce the wines themselves. Whoever produces the wine, some or all of the interventions mentioned in the winemaker paragraphs below will be used. Good winemakers in the traditional mould will seek to minimise the intervention both in the vineyard and the winery. If a grower does not use organic or bio-dynamic techniques, it does not mean that he will produce inferior quality grapes or produce inferior quality wine. Traditional methods often match the grape variety to the soil type and the local climate and appellation rules often dictate which grapes can be used in which region. Some traditional winemakers are committed to "la lutte raisonée" or reasonable struggle which means that the vine grower will only intervene with a pesticide or herbicide when it is absolutely necessary for economic reasons. Most of the the world's finest tasting and high quality wines are made by traditional methods of agriculture and wine making.
Natural wine makers: It is difficult to nail down what is a natural wine producer. They will all, however, use "organic" or "bio-dynamic" growing techniques.
Organic farmers endeavour to maintain a farm in ecological balance with its surroundings and will not try to "import fertility" by usage of chemical fertilisers or pesticides.They allow "weeds" to grow in the vineyard to encourage natural predators and to provide natural fertilisers. Some farmers do not use tractors to plough their land as they feel that it damages the soil. But is using a horse drawn plough any more natural? Nature if left to itself has no use for a plough. Most organic producers will grow their products under the auspices of an approved scheme. I am all in favour of organic farming not because the products are intrinsically better but because it is less damaging to the environment in general.
All products of organic agriculture will be of bad quality if they have been damaged by "pests" disease or bad weather, so wine that is made from poor quality grapes will not produce good wine. The natural wine maker is limited , however, as to what he can do to improve the quality of the grape must. It may not be possible for him to produce a wine in a bad year. The economics of wine production lean towards the methods of the traditional wine maker.
Bio-dynamic farming of grapes involves the use of preparations specified by Rudolf Steiner an early twentieth century philosopher and scientist. One of the preparations involves the use of burying nettle leaves and digging them up later and using them as compost. Another preparation involves burying cow dung over winter enclosed in a cow horn - vegans take note. These types of preparation are controversial to say the least.
There is very little scientific evidence that organic or bio-dynamically produced grapes are of substantially better quality than traditionally produced grapes. But lower yields tend to indicate better quality grapes. The attention to detail of the farmer and the additional care of the vineyard might also improve the quality of the grapes. But what is an organic or bio-dynamic grower to do if his crop is spoilt by by a fungal infestation which is not controllable by natural techniques. I leave that for you to work out yourself. The use of sulphur is permitted in the vineyard to control pests.
Some natural wine producers are opposed to the use of any additives in the wine but some use sulphur di-oxide compounds to help sterilise equipment and prevent the oxidation of the grape must or wine. Natural wine producers do not approve of micro-oxygenation of wine or its filtration. Cultured yeasts are also prohibited. Some do not even fine the their wines or where fining is necessary they only use egg albumen. Some top wine producers are also turning to organic or bio-dynamic methods to produce their wines.
Industrial or Commercialised wine makers: These producers will use a whole panoply of technological and chemical techniques to improve the yield in the vineyard and rectify the wine with chemical additives and techniques such as filtration and micro-oxygenation and of course cultured yeast. The wine produced may not necessarily be harmful or even taste bad but it will taste as if it has been homogenised. How often have you drank a "Merlot" which could come from any country or continent for that matter? Such wine will not stimulate the taste buds. This sort of wine is OK for a barbecue or a party where you do not really care what you are going to drink. In general these wines are also cheaper. Industrial wine production can also ensure that a wine is made even in a bad or terrible year. Additives to and the manipulation of the wine making process can guarantee that a producer produces the same quality and tasting wine, year after year, no matter what is happening to the soil or the weather.
Issues
Now let us examine the issues surrounding the production of natural wine. Is "natural wine" superior to products which do not employ such stringent techniques? How do we define naatural wine? What do we mean by natural anyway? One could argue that a natural process is one where there is no intervention by mankind. If that is so then no product of human agriculture could be termed as natural. If one argues, the other way, that Human Beings are as much a part of nature as any other creature or plant, then humans and all their activities are natural; including the tools and techniques to improve food and beverage production. So where does that place wine production? It is on a sliding scale from where fermentation of wild grapes accidentally produces wine to where a completely industrialised process produces an homogenised varietal branded wine. We should be careful of a lot of the hype surrounding natural wine, it may not be as natural as you think but really just a name.
Wine was first discovered or invented about 8,000 years ago either in Georgia or the Near East, according to the archaeological evidence, but no-one knows its origin for certain. No doubt it was discovered when a farmer left some wild crushed grapes in vat or pot to ferment by accident. The original product would not have lasted long as the primitive wine would have quickly turned to vinegar when exposed to the air and contaminating bacteria. Ever since its first discovery wine producers have been intervening in the vineyard and the winery to improve the production of grapes or the wine making process. They have tried to both improve the quality of wine and its storage to protect it from the ravages of oxygen and heat. Up until the nineteenth century most improvements would have been made on the basis of trial and error.
The primary grape selected for wine production in Europe was the vitis vinifera species from which numerous varieties of black and white grapes were selected according to their suitability to produce red, white and rose wines. Such varieties, of vitis vinifera grapes, include Chardonnay, Merlot, Cabernet Sauvignon and all of the other grapes used for commercial production of wine.
Trial and error was also used to discover and invent fortified wine styles such as Sherry and Port.
The invention of the bottle was also a major step to improve the keeping qualities and transport of wine to export markets.
In the mid-nineteenth century, Louis Pasteur postulated his germ theories and discovered the cause of fermentation. Wine production was subjected to the rigours of scientific examination. Scientific methods started to be introduced in both the vineyard and the winery. The germ theory lead to the discovery that micro-organisms other than "brewer's yeast" were responsible for the spoilage of wines and beers and this lead to the usage of antiseptics such as sulphur di-oxide to preserve wine and other foods and beverages. Since then science and technology have made increasing contributions to the development of the wine industry.
Science possibly became the saviour of the wine industry during the latter part of the nineteenth century, when an outbreak of the phylloxera louse spread from the US throughout the world and completely threatened wine production from the vitis vinifera grapes. Vitis vinifera has virtually no resistance to the louse. The solution was to graft vitis vinifera shoots onto the root stocks of different species of vines from America which were resistant to the vine louse. This means that most of the world's vineyards are planted with vines that are an artificial creation. Where is the nature in that? At the time the alternative solution would have been to use insecticides. Some vineyards in the northern parts of Burgundy grow vines on sandy soils which are not suitable for the growth of the Phylloxera louse; they are therefore planted with purely original root stocks. I have tasted Cremant de Bourgogne produced in this way, from Chardonnay grapes, but I could not tell that it was markedly different from wine produced from grafted root stocks. Vineyards suitable for growing un-grafted grapes can also be found in South Australia, Chile and Portugal and there is debate amongst wine experts whether there is a marked difference in the quality and taste of the wine. A minority of vineyards, including organic and bio-dynamic ones, grow grapes which are uniquely based on un-grafted vitis vinifera scions. Most other vineyards would not remain commercially viable without the human intervention of grafting techniques.
Science and Technology have made further inroads into viticultural practises and techniques including:
Site surveys to find the best locations to plant new vineyards
Trellising techniques to improve yield and vineyard mechanisation
Technology to improve drainage and irrigation where necessary or allowable
Mechanisation of the harvest
Systemic Pesticides.
There have been equally important uses of science and technology in area of vinification including:
Cultured yeasts which are used to standardise the production of wine
The use of sulphur compounds to help prevent the oxidation of the wine
The use of sulphur compounds to sterilise the wine
Flushing the wine with nitrogen or carbon di-oxide to help prevent oxidation of the wine
Adjustments to the acidity of the wine
Adjustments to the sugar content of the wine
Micro-filtration of the wine to sterilise and clear it
Reverse osmosis to concentrate the grape must
Micro-oxygenation to mimic the effects of maturing the wine in wooden barrels
Use of fining agents to clarify the wine.
The ever increasing use of technology is a very controversial subject, especially in the winery where the use of additives and technology such as reverse osmosis can make up for bad quality grapes. One thing is certain, it has lead to the standardisation of wine which all tastes the same depending on the variety of grape used; the wine is clean, clear but sterile. Many many consumers enjoy these wines and so do I sometimes. But for something special, please choose wines which have not been tampered with to the same degree so that they show more character. They are worth the premium that has to be paid. Superior quality grapes produce superior quality wines without the excessive need for the type of adjustments listed above.
But what about some of the claims which are made for "natural wines" which are made by producers who forego even some of the techniques used by classic wine producers.
WINE MAKING
Wine making has come a long way during the last century as technology has had an increasing influence in the commercialisation of wine production.
ADDITIVES:
Sulphur di-oxide or derived salts such as E224 potassium meta bisulphite are used by virtually all winemakers to sterilise the wine to prevent spoilage and to reduce the risk of the wine oxidising during the wine making process or after bottling. Some people are allergic to sulphur di-oxide so they cannot drink most wine. Excessive sulphur di-oxide can denature the colour of red wine and suppress the fruit character of the wine. Sulphur di-oxide is harmless to most people at the quantities allowed unless you have an allergy to it. It should also be noted that sulphites are a natural by product of fermentation by yeast. What difference does it make if man adds the bisulphite or yeast adds it? They are both products of nature. All good winemakers limit the quantity of sulphur di-oxide to a level that does not affect the quality or taste of the wine. Without this preservative some most wine will go off quickly.
It should be possible to make a stable wine without the usage of sulphur di-oxide compounds if the wine is naturally allowed to complete fermentation and stabilise itself. The wine must then be bottled in aseptic conditions to ensure its preservation. Some natural winemakers can achieve this but it should be noted than organic and bio-dynamic approval bodies allow for the use of sulphur di-oxide compounds. It is up to you to decide why.
Ascorbic Acid or E300 : this is also used as a preservative and is another name for vitamin C. Vitamin C is supposed to be good for you. Ascorbic acid helps to keep the wine fresh but of course its use should be limited as some of the by-products of the oxidation of ascorbic acid can discolour the wine.
Copper Sulphate or E519: This is used to remove the taint of hydrogen sulphide in a wine which has not been made properly. So what is it doing there? Modern anaerobic wine making techniques stop any oxygen entering the wine making chain to prevent the reduction of sulphur di-oxide to make hydrogen sulphide. The copper sulphate is added to "cleanse" the wine. Some of the by-products of fermentation itself also produce hydrogen sulphide. Hydrogen sulphide smells of rotten eggs. Before the usage of stainless steel much of the pipework and pumps would have been made of bronze; the copper content of which would have been sufficient to remove small amounts of hydrogen sulphide. Not everything that is modern is better. Hydrogen sulphide is very poisonous; it is not a good substance to have in your wine.
Acacia Gum E414: This is used to fine or clear the wine. It is a naturally occurring substance. It can also alter the feel of the wine in the mouth.
Potassium Ferrocyanide E536: Cyanide, what is that doing in my wine? It shouldn't be there at all but, if it is absolutely necessary, its use should be controlled by a qualified chemist. Potassium ferrocyanide is used to control excessive levels of iron and copper in the wine. Excessive copper can be poisonous. Iron and copper compounds can cause wine to have a haze. The ferrocyanide removes this. Addition of potassium ferrocyanide is illegal in many countries for good reason. Prevention is better than cure so this is one up for natural wine makers!
Citric Acid or E330: Citric acid is a naturally occurring substance which to all intents is harmless. It is used as an alternative to potassium ferrocyanide to remove excess iron. Better than adding potassium ferrocyanide but once again prevention is better than cure. Citric acid is present in grapes at very low level. There should be no real need to add it to the wine making process.It is harmless but it will increase the acidity of the wine.
Sorbic Acid or Potassium Sorbate E200 and E202 respectively: Sorbic acid is used as a preservative to prevent yeast fermenting in the bottle. Its efficacy depends upon the alcoholic strength of the wine; more is need for wines which have a low alcohol level. Some people can taste the Ascorbic acid at levels lower than the EU permits. So what is it doing there? The use of Ascorbic acid can be obviated by good hygiene and effective fermentation. This is also one up for the natural winemakers.
Tartaric Acid E334: Some grapes grown in a hot climates such as Southern Europe , California and South Australia lack acidity. What better way to correct this "fault" than to add tartaric acid to the grape must before fermentation? I see no way that natural wine makers and growers can correct this fault other than breeding grapes that can produce more acid in the berry. But would this be natural? As the planet hots up (unnaturally of course) we can expect to see more and more wineries adding tartaric acid to the grape must. There really is no substitute for high quality grapes which have the right balance of acids and sugars. Perhaps some of the existing vineyard locations are now simply too hot for grapes and all winemakers including natural ones should pack up and move production elsewhere! I can even envisage some growers using huge air conditioned plastic cloches rather than shift location.
Calcium Carbonate E170 and Potassium Bi-carbonate E501: These are used to de-acidify the grape must. Grapes grown in cooler climates, where there is less sunshine, may produce too much acidity even in ripe grape berries. And what is the best solution? Why de-acidify the grape must before fermentation of course. But this process is quite difficult as the acid must really be neutralised rather than removed. Usually the excess acidity is caused by tartaric and malic acids. The addition of calcium carbonate potassium bi-carbonate mostly removes the tartaric acid which crystallises out as either calcium tartrate or potassium bi-tartrate. But these harmless crystals are un-attractive to most wine consumers so they are removed. Calcium tartrate is more difficult to remove from the wine. Excess malic acid is more difficult to remove so "double salt de-acidification" is used: the mind boggles at this one. Prevention is better than cure perhaps it is better not to make wine from grapes that have excess acidity at all. What chance is there therefore for the natural wine maker in, say, England?
In conclusion, a wine which needs to be tampered with by the use of too many additives is probably not worth drinking and it is a pity that wine makers are not compelled to list everything in their wine. If you really knew what was in your wine would you drink it? Most responsible makers of good quality wine will not tamper with their wine too much. The natural wine makers have got a good point; the best quality wines are those which are tampered with the least.
Fining Agents:ural Wine Fining has been used for centuries to clarify wine to remove certain types of protein and polyphenol (tannin) molecules which are held in a colloidal solution; as some of these colloids are unstable they cause the wine to go cloudy before bottling and they are removed by fining agents rather than filtration. Wine will stabilise and clarify itself if left long enough so there should be no need for fining, but some times a harmless deposit is produced in the bottle. Most consumers want to buy completely clear wines which do not throw a deposit. Fining is used to speed up the process of removing the colloids from the wine. Like all wine processes, however, the lesser intervention the better the results. Some commonly used fining agents are the following:
Albumen or soluble protein which is usually obtained from egg whites or refined derivatives thereof. The EU has banned the use of albumen derived from ox blood because of the BSE scare. It is used to fine both red and white wines. Eggs whites mixed with a little wine can simply be added to the barrel. Vegans and some vegetarians would probably not want to drink wine fined with albumen but there is no list of ingredients on the bottle and it is difficult to find out whether the wine has been fined with an animal protein. Unless it is specifically stated on the bottle, it is probably better to assume that the wine is not "vegan compliant" .
Casein: this is derived from milk and is sometimes used to to remove colour taints from white wine.
Gelatine: this is made by boiling and treating animal skins and bones and it clarifies the wine by a simlar action to albumen. No doubt most vegans would be horrified if they knew that this was added to their wine. Gelatine is sometimes mixed with silica sol , which is a mineral to clarify white wine. Gelatine can also be added in combination with certain types of tannin to improve the efficacy of the clarification process.
Bentonite: this is a silica based clay used to remove certain types of protein. If it is over-used it can remove some of flavour components of a wine. Bentonite is also a used for cat's litter. Whatever happened to that cat's pee aroma in the white wine?
Isinglass: this is gelatine which has been obtained from the swim bladders of fish. It is used to fine white wines.
PVPP Polyvinylpolypyrrolidone: this is a water soluble synthetic substance invented in the 20th century and used for the fining of white wines. Why anyone should want to use this substance I do not know.
In conclusion, fining serves a useful purpose to help the effective clarification of wine but of course it should be used in moderation otherwise the flavour of the wine could be spoilt. A good quality wine can be stabilised and cleared without fining but of course this may not suit commercial convenience.
Filtration: Some winemakers argue that filtration ruins wine and should not be used at all. Others maintain that filtration, if correctly applied, has no adverse affect on the wine. A wine that has been allowed to stand in the cask before bottling will clear itself, given enough time, and any remaining solid matter will throw a slight and harmless deposit in the the bottle. Modern industrial processes demand filtration using depth and membrane filters to remove all solids before bottling. Some types of membrane can remove all micro-organisms from the wine rendering it sterile. It is debateable whether filtration is an "unnatural" process or not. I prefer to drink wines which either have no or minimal filtration. Good wine will stabilise and clear itself if left in the barrel for long enough. A well fermented wine will remove all nutrients which will prevent further fermentation in the bottle, this and the alcohol will further help to sterilise the wine. Good wine should not need to be filtered but filtration suits commercial convenience.
OTHER PROCESSES
Some wine makers do not confine themselves to additives, filtration and fining. As if that were not enough, there are some even more dubious processes.
Chaptalisation: What is wrong with adding sugar to the grape must before fermentation? Sugar, in the form of glucose and fructose, is after all a natural substance which occurs naturally in the grape. But, if the grape must has to be chaptalised by adding sugar (sucrose) to increase the alcohol level then the original quality of the grapes must have been found wanting. Grapes grown in cold conditions often do not ripen well enough to produce enough of their own sugars. They are poor quality grapes. So what is the wine maker to do destroy his crop? The addition of sugar is closely regulated; it is banned in Italy and Spain and is only allowed in the cooler regions of France. Some winemakers are tempted to bend the rules when there is a poor harvest. Quality wines should not be chaptalised as it dilutes the flavour of the wine.
Rectified Concentrated Grape Must, can also be used to add sugar (glucose and fructose) content to the pre-fermentation product. This practice is also tightly controlled but a good quality wine cannot possibly be made in this way. There really is no substitute for good qaulity grapes. One up, too, for the natural wine maker.
Must Concentration: This must be one of the most dubious practices of all. It is used when there is a poor harvest to artificially build up the concentration of sugars in the grape must. It is only carried out under strictly controlled conditions. The chances are you will end up with an industrialised tasting bulk wine. Perhaps it would be better not to produce wine but economics dictate that something must be done to improve a poor harvest.
FERMENTATION
Fermentation is the most important process of all. Yeasts have evolved to have two methods of growth:
i) aerobically in the presence of oxygen where they convert the sugars present in the grape must to water and carbon di-oxide
ii) anaerobically in the absence of oxygen where they convert sugar to alcohol and carbon di-oxide. Aerobic fermentation is much more efficient so the yeast is able to grow quickly. But, of course, if aerobic fermentation were to continue until all the sugar was consumed no alcohol or wine would be produced. In a sealed container the oxygen is quickly used up and encouraged by the build up of carbon-dioxide the yeast starts to grow anaerobically to produce alcohol. If this process is allowed to continue "naturally" all the sugar is used up to produce a dry wine.
There are many ways of controlling the fermentation depending on whether a sweet or semi-sweet wine is the intended product. Industrial wine producers may wish to control the fermentation to suit economies of scale and to reduce unit costs or to fit in with delivery deadlines etc. The "natural" or traditional process of fermentation does not easily fit in with modern means of production.
Control of Temeperature: Fermentation produces heat and its control is essential to the type of wine being produced. Red wines require more skin contact with the must to extract colour and flavour compounds. A cooler temperature is required to preseve the flavour of volatile aromas. White wines do not rely upon the contact of the grape skins with the grape must so they are fermented at a lower temperature. There is an optimum temperature for the fermentation of every wine, and in traditional wineries this is achieved by the usage of smaller fermentation vats and barrels which have a high surface area to volume ratio which dissipates heat without the need for refrigeration. Where much larger vats are used, in an industrialised process, artificial cooling controlled by thermostats is necessary. Where there is excessive cooling undesirable volatile esters could be retained in a red wine leading to an excessive taste of artificial fruit flavours and homogenised tasting wine. If the grape must is cooled to around 5 degrees celcius fermentation is stopped.
Stopping the Fermentation: The main reason for stopping fermentation is to produce a sweet or semi-sweet wine before all the sugars in the grape must are depleted. The traditional method of stopping fermentation is by fortification with grape spirit or brandy and in France this is termed mutage. Port is produced by this method. Wines may also be fortified to preserve them and to prevent refermentation after the primary fermentation has been completed. Sherry is produced by this method.Fortification is a "natural " method of sterilising the the wine.
Industrialised processes have been invented to stop the fermentation according to the commercial convenience of the wine maker to produce cheaper sweet wines or sparkling wines or both. Some of the devices used are:
i) Sterilising the wine : Formerly cheap sweet wines were made by stopping the fermentation by killing the yeast with sulphur di-oxide but nowadays the additon of sulphur compounds is strictly limited. Other methods of stopping fermentation include the pasturisation of the wine must to kill the yeast. Why do this ? This is totally unnecessary. I can understand why one would need to pasteurise milk for health reasons but any one who has drunk real milk straight from the cow will realise what a difference pasteurisation makes to a beverage.
ii) Physical methods to remove yeast: Another way to stop the fermentation of the must is to use micro-filtration or centrifugation to remove the yeast. This is also unlikely to improve the quality of the wine and it is only really done for commercial reasons. Who wants to drink wine which has been subjected to micro-filtration or pasteurisation? If the public knew what was happening, I am sure they would not touch wine produced by these methods.
In conclusion, the best way of arresting the fermentation of the grape must is by fortification with brandy or grape spirit which also serves to preserve the wine and sterilise it. It should be noted that Asti (formerly Asti Spumante) is produced by artificially stopping fermentation by increasing the pressure of carbon di-oxide in a steel vat. This is sometimes referred to as the Charmat method of producing a sparkling wine. Asti is therefore a sweet sparkling wine with a low level of alcohol - glug glug - I think that most Asti is ghastly.
YEAST
You would think that that there would be no controversy about yeast, as natural yeast has been just as important as grapes ever since wine was first discovered or produced. The primary species for making wine is saccharomyces cerevisiae. This occurs naturally in the environment in general and on grape skins in particular. But, of course, the application of science has lead to the artificial selection of cultured yeasts to meet a particular taste or set of properties to improve the fermentation process and the economic production of wine. Needless to say, when cultured yeasts are used it has encouraged the standarisation of winemaking and the standardisation of taste. If you want an individual tasting wine it is better to leave it to nature even if this means a a more expensive means of production.
MALO-LACTIC CONVERSION or SECONDARY FERMENTATION
After alcoholic or primary fermentation, by yeast, some wines naturally undergo malic-lactic conversion, where bacteria, such as those from the Lactobacillus genus, convert the harsh malic acid in the wine to a softer lactic acid. This process can be artificially induced by injecting the bacteria into the wine. Once again, if this is overdone the wine can become tainted with a buttery or cheesy taste; after all there is plenty of lactic acid in cheese. Malic-lactic conversion is mostly applied to red wine. Malic acid, of course, gives apples their tart taste. Malo-lactic conversion should be completed before the wine is bottled as the process produces carbon di-oxide; this is unwanted in a still wine hence the use of sulphur di-oxide, and other meausures, by some wine makers to sterilise the wine.
CONCLUSIONS
By now you might be concluding that the least intervention there is in the vineyard and the wine making process the better. And to a certain extent you are right. But, if winemaking and viticulture were left to their own devices there would be no wine industry whatsoever. At most it would remain a cottage industry and we all know what auntie's wine tastes like even if it is produced from organically grown grapes from the back garden.
As to claims that natural wine is better for than other forms of wine please consider this; the most dangerous substance in our wine is alcohol. This is a perfectly natural substance but just like the toxin in ergot of rye, also natural, it will kill you if you consume too much in one go. It will also damage your physical or mental well being or both if too much is consumed over a long period.
The fact that it does not contain many of the additives allowed by the EU does not necessarily mean that natural wine is less toxic. For the average adult to be seriously affected by suphur di-oxide poisoning they would have to drink wine in such huge quantities that the alcohol would kill them first. If you drink too much of any sort of wine, one day you might wake up with more than a hangover.
Is natural wine better for your health if you drink it as a replacement for traditionally made wine or industrially made wine? There is no real evidence for this. This also raises the issue if wine is good for your health at all. There is some evidence that wine and other forms of alcohol might have beneficial effects on the cardo-vascular system but this is not definitive. No doubt there are substitutes for the health promoting ingredients found in wine, therefore wine is not uniquely a beneficial beverage.
So why drink wine at all? My reason for drinking wine is for the sociability and the conviviality that it generates. But, most of all, it is the perfect companion for good food. As far as taste is concerned, good wine is the best tasting drink. Wine should also reflect the taste and character of the region of where the grapes are grown. You are more likely to find these attributes in a well made traditional or natural wine. Traditional and natural wines should mature into a better product if they are stored properly. But, beware some of these wines are not as good as the marketing hype pretends them to be.
There is good reason to drink natural wine for the health of the environment - the farming techniques are less damaging.
So where does this place industrial or commercialised wine? Whilst some of it tastes quite good almost all of it tastes the same within the brand or grape variety on the label: and they are quite simply boring. Industrially produced wine is probably no worse or better for your health than any other wine so this is not grounds for dismissing it. One thing is certain - the farming techniques used for industrialised wine making do nothing for bio-diversity.
ECONOMICS
Industrialised wine production has brought down the cost of wine and introduced wine drinking to the public in general. Traditional and natural wines are more expensive to produce. There is now a huge demand for wine which could probably not be satisfied without industrialised wine production. What would happen if the public only had access to traditional and natural wine? Would the prices go up so much that ordinary wine drinkers would not be able to afford to drink wine regularly? There is a place for industrialised wine but the producers should be encouraged by the wine buying public to improve the quality of their product. They should be encouraged to reduce the additives and manipulation of their wine which are there just for production convenience. The general public could do this by drinking a lesser amount of good wine as opposed to drinking large quantities of plonk. They might also be doing a favour to their health and help improve the environment. There is not much room for industrial wine on my wine rack but there is some space for good natural wine.
