This may come as a shock to some, but I found this forum, while looking for wine making forums!!!
I have been making wine since the 1970s as a hobby and never planned to do anything more with it. It was often occasioned by a windfall of fruit from a restaurant, people I knew with fruit trees or running into a lot of grape juice that was near expiration. So I'm an amateur.
However, I quit using baking yeast a long time ago. My wife told me that all of my wine had a weird finish similar to Fritos corn chips. No matter how I babied the wine, this was the case. Then we moved out of the sticks and into a city with a couple of wine making shops. The first batch I made with Montrachet yeast was amazing, so I never looked at baking yeast again. I have also made wine where it's hideously expensive, like the year I spent in Trinidad.
These days I have been making wine from blueberries, which are plentiful around here. The first batch was so good I just kept repeating the same recipe. What I don't get is consistency. So I thought I'd read up on how other wine makers deal with this issue.
