A first for me...this spring, the wine started showing signs of activity. In the barrel since being made, (made from CA grapes in October), I noticed a re-fermentation occuring. I racked it off the lees, gave a dose of meta, and waited. It has now been 3 weeks and still I see small bubbles rising. Even more troubling is the fact that the wines flavor has changed from the fruit notes to being more acidic. Could be VA, I don't know. At first I was hoping it could be a late malo/lactic fermentation. But I am now dreading the worst. This is the first time anything like this has happened to me...any thoughts? I fear all is lost and I will have a large amount of vinegar down the road.
