2 years ago I put some saison on Concord grapes, about 1.5 pounds per gallon if I recall correctly. It turned into a total Jolly Ranger beer. The grape was overpowering and fake tasting. I hated it. My wife liked it, but you couldn't drink more than a single glass. I only had about 2.5 gallons, so I blended half in with another saison once there was room in the keg. That was still not to my liking, but I got through it. I used a gallon as a dreg reservoir for sour beers which has slowly been diluted as I used some and replaced with other wort.
