Welch's frozen grape conentrete

I followed directions from Jack Keller's site.Primary fermentetion went well,racked into secondary,took a specific gravity reading at 1.000(1 week). Thought I'd try a samle to see how it is coming along and taste like vinegar. Is this ruined or is there something else I should do?

HD93, I bet DGreene knows better than Jack Keller Hopefully he'll see this soon

Two things, first of all it is not quite done fermenting. Second of all new wine tastes like crap, it's just a fact. Also yeast produces some vinegar so having some is not a big deal. As long as you are not making vinegar somewhere in the area the chances are that you did not produce it. Wine needs to age at least 3=6 months before it starts to taste right. Age it in bulk and see what happens.

The wife just had a sample and said it's fine.I just wanted to see how it was coming along. Maybe I had some meta left in the glass? Thanks for your help, i'm new to wine making.

Meta? You mean sulfite?

Yes, I actually rinse everything with water real good, then use Potassium Metabisulphite before and after each time I use hydrometer, spoon, etc.

Sounds like you are doing everything right.
