I am just about able, now, to appreciate red wine now that I have stopped taking antibiotics for a month. However , I won't be winning any wine tasting prizes. White wine still tastes awful to me. Also to complicate matters I contracted diabetes at around the same time as my chest complaint. I don't know whether the two complaints have exacerbated one another: some doctors think yes and others think no, The diabetes means that I have to limit what I drink to one glass of wine with food, which is no big deal for me, as I rarely used to drink more than a 250ml glass of wine per sitting especially in my latter years. However, the days of drinking half a bottle on rare occasions are gone.
Whenever, I went to a wine-tasting I always used to spit out the wine after sampling it. Hopefully, my sense of taste will come back fully and I shall be able to taste and recognise all good wines and do plenty more spitting.
It is surprising how bad it is to lose your sense of taste: I almost lost it completely when I contracted Covid19, but it came back very quickly. In some respects a heavily modified sense of taste is worse, as some foods and wine taste foul especially foods like smoked fish and some fruits. The fruitiness of wine is covered up by a horrible bitter taste. I hope that I never have to take antibiotics again, but they did save my life if not my sense of taste. The quality of your life is considerably reduced when you become "taste blind", and I don't wish this on anyone.
