So, final outcome - pretty delicious! I let this sit on the peanut butter for 4 weeks total. At time of kegging, i used just a tad bit of chocolate syrup to give it a bit more chocolate aroma. All in all...2 weeks later, how's it going?
1lb PB2 in boil
4oz Ghiradeli cocoa powder in boil
2lbs natural pb in secondary
2tbsp chocolate syrup in keg
Pretty happy with it. I like the flavor, it strongly resembles a reese's peanut butter cup. There's a couple of changes that i would make at this point but this is a solid start for sure!
