Well I took advantage of a sale that Meijer currently has on Blackberries AND Blueberries today, and purchased 5# of "Black" and 2# of "Blue." $12 total is a deal by MY standards! I plan to make a 1-gallon batch, and after perusing a number of recipe threads here, I've decided to ferment these together. I'll be testing my pH, of course, and see where I'm at as well as my intial S.G. to determine amount of sugar to add. I've been reading that Blueberries are somewhat touchy to ferment, so my question is: it's only 2#, so with them being added to the 5 lbs of Blackberries, does anyone think I should have any concern with this fermenting well? I will use pectic enzyme, as well as some nutrien and energizer to help things along. I am going to use the 71B-1122, and maybe a a little oak (but the jury is still out on the oak addition.) Maybe I'll wait to see how it tastes after a few months and go from there. Thanks to all for ANY input you may have!
