Hi Norm

What kinds of wine are you making and is it becoming vinegar or is your
wine sour?

Sour wine is due to high acid content. Cleanliness (or the lack
thereof) will not cause your wine to be sour. High Total Acidity and/or
low pH are the cause of a sour wine.

Vinegar is caused by acetobacteria. This bacteria requires oxygen to
flourish. And if it is present then there are some problems with
cleanliness.

How do you store your wine? How much headspace is there in your
containers? These are the things that you'll need to determine first
before we can figure out what is going on with your wine.
