I did it with a Blackberry-Merlot. I couldn't keep the stuff. I actually bottled it in used Arbor Mist bottles with new screwcaps. I think it was 15% abv. Way too hot, too sweet, but everyone liked it except me. I started it as a 5 gallon instead of 6 and added sugar, fermented dry, then used all the sweetening pack that is for 6 gallons. It would have been better if I had started it outas the normal 6 gallons, chaptilizing just to about 11 or 12%PA, then proceeding as normal.
