I came across this wine at Klingshirn Winery in Avon Lake, Ohio and think it is a blend of Concord and Niagara grapes but am not sure. Anyone know how to duplicate this wine, or know of a kit out there that resembles it? Forgive the spelling of the wine name if it's incorrect.

John, the rise in temp did the trick. I too thought I added too much sulfite. I used 1 Campden tablet per gallon. This seemed to work before so I was worried. Anyway, it's going strong now. Thanks.
