I had bittersweet success with this, and could use an opinion.
midnight wheat instead of carafa
5 oz cocoa powder in the boil
5 oz cocoa nibs in secondary
10 mint tea bags last 5 min of boil
4 mint tea bags in secondary
.75 lb lactose in the boil
.25 lactose in secondary
Sightly low efficiency because of a crappy steel braid, final abv 5.4%.
Two days after burst carbing in the keg, it was awesome. Mint and chocolate were prominent and balanced. It smelled and tasted like a girl scout cookie. My friends and I were impressed.
But after only a week, the mint faded big time. So I sanitized and added 3 more mint bags into the keg, and it solved the problem... for another week.
I want to do this again, and maybe bump the OG up to ~1.072. Any suggestions regarding how to keep the mint flavor from disappearing?
