You must be able to boil at least 3.5 gallons (13 L) of wort. In a large kitchen pot, steep crushed pale malt in 3.0 qts. (2.8 L) of water at 149 °F (65 °C) for 45 minutes. While grains are steeping, begin heating 2.75 gallons (10 L) of water in your brewpot. Lift grain bag, place in a collander and slowly rinse grains with 1.5 qt. (1.4 L) of water at 169 °F (76 °C). Add “grain tea” from steep and dried malt extract to your brewpot to make at least 3.5 gallons (13 L) of wort. Boil wort for 90 minutes, adding Columbus hops at the start and Ahtanum hops at knock-out. Stir in liquid malt extract for the final 15 minutes of the boil. (Keep a pot of boiling water handy and add water if brewpot volume drops below 3.5 gallons/13 L). Cool wort, transfer to fermenter and top up to 5.0 gallons (19 L) with cool water Add yeast from 1-quart (1-L) yeast starter prepared 2–3 days earlier. Oxygenate well and let ferment for 3–5 days. Rack into a secondary fermenter and add Amarillo hops in a sterilized muslin bag. Rack after one to two weeks, and bottle or keg as desired.
