1.3 lbs. (0.6 kg) Gambrinus Honey Malted Oats
10 oz. (285 g) Weyermann chocolate wheat malt

4 oz. (113 g) Simpsons chocolate malt

Step by step
Mash the grains at 154 °F (68 °C) for 60 minutes. Raise mash to mash-out temperature of 168 °F (76 °C) and lauter as normal. Collect enough wort pre-boil to allow for 5.25 gallons (20 L) in your fermenter.

Boil for 90 minutes, adding hops as per the schedule. At the end of the boil, cool wort to slightly below fermentation temperature, 65 °F (18 °C), and pitch yeast (aerate if using liquid yeast). Ferment at 67 °F (19 °C) until complete. 

Rack to a keg and force carbonate or add priming sugar and bottle condition.
