Peanut Butter Porter V 3.0

Almost an entire year after I starting telling my friends to expect a new batch of Peanut Butter Porter 'soon', it's finally here. This builds off my last try and keeps several of the uniquely random aspects of the beer, such as lager yeast (to help emphasize the malt and peanut flavors) and oats (to help with head stabilization).

Grains/Extracts

• 8oz Chocolate Malt


• 12oz Black Patent Malt


• 4oz Roast Barley


• 3oz Oats (Steel Cut, not instant)


• 8oz Crystal, 60L


• 8oz Munich 10L


• 4.5lbs DME

Hops

• 1oz Perle 7.6% AA


• 1oz Fuggle 4.5% AA

Yeast

• While Labs Oktoberfest

Adjuncts

• 8oz De-oiled peanut butter ("100% Real Peanut Butter" brand) - see this post for de-oiling info

Directions

• Infusion mash


• Added DME and Perle hops at beginning of boil


• Added 2oz of PB at 5min, 25 min, 40min, 55min


• Added 1/2 oz Fuggle at 40 and 55 min


• Ferment a week, then rack. Pay attention to the surface of the beer to keep any excess oil from getting to the secondary


• Secondary 3 weeks at 50F (remember lager yeast), reracked to remove trub and remaining oil slick


• Bottled at 6 weeks, age at least 2 weeks, preferably 3 before drinking. The peanut butter flavor will continue to change.

Gravities

• OG 1.047


• FG 1.014

Nose: Some malt sweetness with a noticable arroma of peanut butter. No hops. There should be some, maybe mine are old and have gotten oxidized.

Pour: Dark with highlights. Lasting medium head (a worry with the peanut oil, but the oats seem to be doing their job).

Taste: Medium body, a little low for a porter (probably the result of the lager yeast). The peanut butter pushes through the malt (again, not much in the way of hops) as the beer moves back along the tongue. Strong peanut butter flavor in the swallow.

Conclusion: Peanut butter without the oil is crumbly but I still ended up with large clumps in my brewpot. 8oz seems like a sufficient amount with homebrew equipment/methods. I'm going to keep trying different de-oiling techniques to see if I can get more of it into suspension. This beer is highly drinkable, I recommend you try it yourself.
