Tepe: I did an f-pac withtwo pounds of same frozen blueberries, and a a few cans of blueberries , maybe one can of blackberries (typically very good quality from Oregon) Reduced over medium heat, cooled, strained,added, stabilized.Strange , Iknow, but very much a clove taste. Did not sweeten. No wine conditioner. I think I'll open a second bottle tonight and check it. Thanks.
