UT - I mix all my FW flavors at 12.5% in 70/30 and 18% in 40/60 FWIW
I tried Mr. GIR's suggestion of 15% in 50/50 and liked it better when I kicked it to 16% 50/50
Thanks for the replies. I use 80/20 and have been mixing my PB at 12.5%. I'm going to up it to 15% and see if I can get some flavor. The MBV bottle I got on the first order must have been a "fluke" I wish I could get some more just like it.
I just tried Capella Peanut Butter at 5,10, and 15% and all I taste is varying strengths of burnt popcorn.
