We did grape again, mainly cuz I wanted to cut more back on sugar. We did 14 bottles using the large batch (which was almost just right maybe a tad sweet) and used 1/2 tsp of sugar. Pulled a test bottle at 5 days and it was perfect!
Using a little bit of leftover large and all of medium batch (was just right less sweet than large) we made 9 bottles of plain w 1 tsp sugar.
The large batch was good not too strong or sweet. We made 12 bottles of grape ape w 1/3 cup organic concord grape juice and 3/4 tsp sugar. The medium batch was a bit stronger but not too much. We made 10 bottles with 1 tsp sugar.
