Step by Step
Mash at 150 °F (66 °C) for 30 minutes, start lautering slowly. Collect 7.5 gallons (28 L) in the brew kettle and boil for 75 minutes adding hops as indicated. After knockout, cool the wort down to ~190 °F (88 °C) before adding the first coffee addition. Ferment at 63 °F (17 °C). After fermentation has slowed down you can add the cocoa nibs and bloomed cocoa powder directly to either the primary or secondary fermentation vessel. Let the beer sit for one more week. Using a sanitized growler, draw off a 1/2 gallon (~2 L) from the fermenter onto the second addition of coffee for a 24-hour cold extraction of the coffee beans. Place growler with beer and coffee beans in a refrigerator for 24 hours. Strain the beer back into fermenter and you’re ready for bottling/kegging.
