Hey Mad, I brew a chocolate peanut butter porter that I enjoy alot and has become a favorite around this time of year. The hardest thing about brewing with peanut butter is the oil content in the peanut butter. I have tried drying out a jar of peanut butter on paper towels for a few weeks but I did not like the results. I tried peanut butter extract, this turned out great but you knew in the taste that it was extract that was used. Then after searching I came across peanut butter powder. This stuff is great, very little if at all any oil content. The directions are to mix with water and you have peanut butter. So I said fuck it lets try it in a beer. So I went over to the old BCS and looked up JZ's chocolate hazelnut porter and replaced the hazelnut with the peanut butter powder and used the same quantities as the chocolate powder. This turned out great but the only thing is that the powder sludge from the peanut butter and chocolate took up about 1/4 of the fermenter when settled. To me that is alot of wasted space. So now I use coca nibs instead and cut the chocolate edition in half. I just brewed this again and tried using 2lbs of blanched peanuts in the mash; we will see how that turns out. Porter recipe below as well as links to extract and powder. Good luck and let me know what you come up with, Cheers

Shook carboy to swirl sludge and then cold crashed at 45 degrees for 2 weeks. Letting the sludge sit for a while you extract more of the peanut butter and cocoa flavors. If still not enough peanut taste add 5ml of peanut butter extract to keg at a time.
Beer ages well and more of the flavors come out with age.
