I added grape concentrate to boost the sweetness of a dry wine at bottling and added sorbate. The flavor is good, but there is some kind of gas in the wine. Any thoughts on what happened?
I made a Muscadine wine this year that ended up very dry with harsh flavor. I wanted it to have more of a grape flavor so I added some grape concentrate to it. I achieved the flavor that I wanted, but there is some kind of gas in the wine (you can see it fizzing, like a soda). What have I done? By the way, I used potassium sorbate (1/4 tsp per gallon) before I added the grape concentrate.
