I made a batch of Cabernet this past fall. The grapes were a little over ripe and the acid was low so I added quite a bit. Testing showed it was fine, I completed MLF (which testing shows now at 0) and still, the wine just tastes acidic. It's aging now and I've racked a couple of times. I did cold stabilization and still it tastes very acidic. Testing shows the numbers are good, but the taste is not right. Should I try to back sweeten with a simple sugar solution? I'm afraid to use conditioner since I used the MLF on it. It's sitting on dark toast American and medium toast French oak right now. The oak has mellowed it a bit, but I just can't seem to get over the acid on the finish.
