I tasted tested 2 bottles of my homebrew apple cyder I started 2012-07-07. Same apple juice/yeast, but one was made with berry juice and the other with berry extract.
The bottle with the berry extract tastes like a normal apple cider, rather tart, very little berry flavor.
The bottle with the apple/berry mixture has a really good mix of flavors, I like the flavor. Now I need to work on how sweet/dry the cider is..
And I used bentonite to try to clear the cider, it did not clear at all.
