Are you thinking of putting peanut butter in your beer?
I have used powdered peanut butter (PB2), as that has most of the fats/oils removed.
Even so, it doesn't add any fermentables so is just added in section I (special instructions).
I spent lots of money on booze, birds and fast cars. The rest I squandered
I've stopped drinking, but only when I'm asleep
I ONCE gave up women and alcohol - it was the worst 20 minutes of my life

Okay. So here it goes... This recipe is from the Brooklyn Brew Shop's Beer Making Book. I contacted BBS to get the OG/FG and they kindly responded back with those numbers. I found a PDF online (" onclick=";return false; ... ctions.pdf) which indicated that there should be 3.8 L of wort at flame out. I multiplied that number by .96 to estimate VAW and put that number in as VAW. Hops were only listed as the type and the weight. There were tables in the book giving a range of average AA% for the hops. I simply took the middle number in that range and plugged it in along with the weight of the hops to be added. It also indicated 1/3 Cup of Natural Peanut Butter with the oil skimmed off. I found the weight of 1 Cup of Peanut Butter and multiplied it by .33 to find the approximate weight. The recipe is for 1 gallon of beer. Feedback would be greatly appreciated.
