Here's a 5-gallon all-grain recipe for a Pumpkin Flavored Brown Ale:
- 9 lbs (4.1 kg) Pale Ale Malt
- 1 lb (0.45 kg) Munich Malt
- 12 oz (340 g) Crystal 60 Malt
- 8 oz (227 g) Chocolate Malt
- 8 oz (227 g) Victory Malt
- 1 lb (0.45 kg) Pumpkin Puree (canned or fresh)
- 1 oz (28 g) Fuggle Hops (60 minutes)
- 0.5 oz (14 g) Fuggle Hops (15 minutes)
- 0.5 oz (14 g) Fuggle Hops (5 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 Brown Ales)
- 1 tsp (5 g) Irish Moss (clarifying agent)
- 5 oz (142 g) Priming Sugar (for carbonation)
- Mash: In a large mash tun, combine the Pale Ale Malt, Munich Malt, Crystal 60 Malt, Chocolate Malt, and Victory Malt. Heat 3.5 gallons (13.2 liters) of water to around 152°F (67°C). Add the water to the mash tun and stir well. Allow the mash to rest for about 60 minutes, maintaining the temperature around 152°F (67°C).
- Sparge: Heat 4 gallons (15.1 liters) of water to around 170°F (77°C). Slowly pour the hot water over the mash, rinsing the grains to extract sugars. Collect the runnings in your brew kettle.
- Boil: Bring the wort to a boil. Add the Fuggle hops at the specified times (60 minutes, 15 minutes, and 5 minutes remaining in the boil). Stir in the pumpkin puree, cinnamon, nutmeg, allspice, and ginger during the last 10 minutes of the boil. Also, add the Irish Moss to aid in clarifying the beer.
- 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. Typically, a Brown Ale yeast performs well at around 65-70°F (18-21°C). Allow fermentation to proceed for about 1-2 weeks or until the desired final gravity is reached.
Remember to sanitize all equipment thoroughly throughout the brewing process to maintain a clean and healthy fermentation. Additionally, feel free to adjust the recipe to suit your personal preferences or experiment with different spices to achieve the desired pumpkin flavor. Cheers!
