We tasted this sparkling wine as an apéritif when we joined our friends for dinner. Our host is a bit of a wine expert and asked us to guess the wine blind. I didn't do so bad as I guessed in was a high quality Prosecco; at least I got the country right. My wife was a little more circumspect. She has got a really good sense of smell. She was holding the wine at waist level and the look on her face was a picture. I could tell from her expression that the wine was not Champagne well before she expressed an opinion. She is from the Champagne region of France.
The wine turned out to be Franciacorta Brut NV from the Brescia province of Lombardy in northern Italy. This sparkling wine is made by the champagne method. The wine is very fine and of excellent quality with a "biscuity" flavour reminiscent of Champagne. You can also taste the umami flavour of the yeast after the wine has rested on its lees. The wine was bone dry and has very fine bubbles. Franciacorta is produced from Chardonnay grapes in gravel and limestone based soils and the taste resembles Crémant de Bourgogne which is also produced by the champagne method from grapes grown on limestone soils - mostly Chardonnay and Pinot Noir. It is of much higher quality than most of the Prosecco produced in the Veneto region. Most Prosecco is not produced by the champagne method, so the secondary fermentation takes place in a tank. There are, however, some higher quality Proseccos that are made by the champagne method, hence my confusion, or that's what I like to think.
Why did my wife not even have to taste the wine before she recognised that it was not Champagne? She grew up in Champagne and is completely familiar with the wine, she doesn't need to become "all analytical" she just recognises Champagne by its smell and doesn't even have to taste it - like I do. She never gets it wrong like me, as I have mistaken an English sparkling wine for Champagne at a blind tasting.
My wife and I had not tasted Franciacorta before, but we shall drink more of it in the future even though it is more expensive that standard Prosecco. However, we will still stay loyal to the world's best wine like true Champenoises and an honorary male one.
