Step by Step
Make your brewing water by combining 6 gallons (23 L) of soft, distilled or RO water with 1.5 tsp. gypsum. Steep grains in 2.0 qts. (1.9 L) of this water at 158 °F (70 °C). Steep for 30 minutes, then rinse with 1.0 quart (0.94 L) of water at 170 °F  (77 °C). Add dried malt extract, corn sugar and water to make 2.0 gallons (7.6 L) of wort and bring to a boil. Once initial foaming subsides, add bittering hops and boil for 45 minutes. Do not let the wort volume dip below 2.0 gallons (7.6 L) during the boil. Add boiling water to make up volume if this happens.  With 15 minutes left in boil, turn off heat and stir in liquid malt extract, Irish moss and flavor hops. Stir until extract is dissolved, then resume heating. (Keep the boil clock running.)

Add aroma hops at end of boil. Cool your 2 gallons (7.6 L) of wort (in sink or with chiller). Once cool, let sit (covered) for 15 minutes. Transfer wort to fermenter, leaving the majority of the sediment in brewpot behind. Add water to make 5 gallons (19 L), aerate and pitch yeast. (Rehydrate yeast — in a clean, sanitized measuring cup — as described on package.) Ferment at 72 °F (22 °C) until fermentation is complete — about 3 days, when I brewed it. Taste small sample. If you don’t taste diacetyl, rack the beer directly to keg or bottling bucket. If kegging, force carbonate beer for 3 days at around 30 PSI. When done, release pressure from keg and adjust regulator to proper dispensing pressure for your system. If bottling, keep bottles warm (74–80 °F/23– 27 °C) for five to six days, then chill in refrigerator for two to three days before opening.

“I brewed this beer on a Sunday and served it to my homebrew club the next Saturday. I thought it would still be green at that point, but it actually tasted finished Friday evening. I designed the recipe and procedures to not only yield a beer that would ferment and conditionquickly, but one that would be quick to put together on brew day.”
