Here's a 5-gallon extract recipe for a Black Pumpkin Stout:
- 6.6 lbs (3 kg) Dark Liquid Malt Extract
- 1 lb (0.45 kg) Roasted Barley
- 8 oz (227 g) Chocolate Malt
- 8 oz (227 g) Crystal 60 Malt
- 1 lb (0.45 kg) Pumpkin Puree (canned or fresh)
- 1 oz (28 g) Cascade Hops (60 minutes)
- 1 oz (28 g) Willamette Hops (15 minutes)
- 1 tsp (5 g) Cinnamon (ground)
- 0.5 tsp (2.5 g) Nutmeg (ground)
- 0.25 tsp (1.25 g) Allspice (ground)
- 0.25 tsp (1.25 g) Ginger (ground)
- 1 package of Ale yeast (suitable for Stouts)
- 1 tsp (5 g) Irish Moss (clarifying agent)
- 5 oz (142 g) Priming Sugar (for carbonation)
- Steep Grains: In a large pot, bring 2.5 gallons (9.5 liters) of water to around 160°F (71°C). Add the Roasted Barley, Chocolate Malt, and Crystal 60 Malt to a muslin bag or grain steeping bag. Place the bag in the pot and steep the grains for about 30 minutes. Remove the bag and allow it to drain, but do not squeeze it.
- Boil: Bring the pot to a boil and remove it from the heat. Stir in the Dark Liquid Malt Extract until fully dissolved. Return the pot to the heat and bring it back to a boil. Add the Cascade hops and boil for 45 minutes. Then, add the pumpkin puree, cinnamon, nutmeg, allspice, and ginger. Boil for an additional 15 minutes. Finally, add the Willamette hops and Irish Moss during the last 5 minutes of the boil.
- Cool and Transfer: After the boil, cool the wort using an immersion chiller or other cooling method. Transfer the cooled wort to a sanitized fermenter, leaving behind any sediment or trub.
- Fermentation: Pitch the yeast into the fermenter and seal it with an airlock. Ferment the beer at a temperature appropriate for your chosen yeast strain. For a Stout yeast, a temperature range of 65-70°F (18-21°C) is typically suitable. Allow fermentation to proceed for about 1-2 weeks or until the desired final gravity is reached.
As always, make sure to sanitize all equipment thoroughly throughout the brewing process to maintain a clean and healthy fermentation. Feel free to adjust the recipe to suit your personal preferences or experiment with different spices to achieve the desired pumpkin and stout flavors. Enjoy your brewing experience and cheers!
