Do most folks "normally drink" sour milk? Probably not on purpose, but many use it in cooking and baking.
Again, and for the last time, we are not talking about the water we drink; we are discussing the water we use in making wine. These are two distinct issues and only very loosely related because there is a general belief that if the water one uses to make wine is "drinkable," it is "usable" (not preferrable, recommended, desired, required, etc.). Personally, I consider this a minimum criterion. If I were talking about what water I would like to drink, I would likely choose spring water, first, purified water, second and tap water (assuming it is a good quality such as we enjoy here in central Ohio), third.
Lastly, the idea that distilled water does not have all that yeast desires is a new one on me. I agree that it does not contain sugar, if that is what is meant. As far as I know, that is all that the yeast cells need, other than an acceptable temperature in which to work.
In any case, no one has offered a scientifically supported reason to me as to why I should not use distilled water and I will continue to do so. I recommend that others follow whatever path they deem to be correct.
