I have maybe 20 oz of muscat grape concentrate left over from a Midas Touch batch I did awhile ago. I was trying to figure out what to do with it (it is just sitting in the freezer). I was thinking of making 5 gallons of Imperial Stout with cascade hops and adding some of the concentrate as fermentation dies down. I was thinking this might end up sort of unique w/ a floral aroma, but really I have no idea. Is there anything obviously gross about this?
