White Labs WLP001 California Ale

DIRECTIONS

Mash at 153°F (67°C) for 60 minutes, then rest until conversion is complete. Boil for 120 minutes. Pitch the yeast and ferment at 64°F (18°C) to start, allowing the temperature to rise to 67°F (19°C) near the end of fermentation to ensure full attenuation.

After fermentation is complete, in separate mesh bags, add to the fermentor 8 oz (227 g) of roasted cacao nibs and one vanilla bean split lengthwise. Leave the cacao nibs in contact with the beer for 1–3 days, tasting daily and removing cacao nibs when desired flavor profile is achieved. Condition for 2–3 weeks while aging with the vanilla bean, before packaging at 2.3 volumes.
