Wyeast 1968 (London ESB) or White Labs WLP002 (English Ale) yeast
3⁄4 cups (150 g) dextrose (if priming)

Step by Step
Mash the grains at 159 °F (71 °C) for 60 minutes. Mash out, vorlauf, and then sparge at 170 °F (77 °C) to collect enough wort to result in 5 gallons (19 L) after a 90-minute boil. Boil the wort 90 min­utes, adding hops at the times indicated in the ingredient list. After the boil, cool, aerate, and pitch yeast. Ferment at 68 °F (20 °C). Add dry hops after fermentation slows for 4–7 days. Bottle or keg as normal.

Partial mash option: Reduce the 2-row pale malt in the all-grain recipe to 1.33 lbs. (0.6 kg) and add 8 lbs. (3.6 kg) extra light dried malt extract. Steep crushed grains in 3.2 quarts (3 L) of water at 159 °F (71 °C) for 45 minutes. Wash the grains with 1 gallon (4 L) hot water. Top off brewpot to 6.5 gallons (25.6 L). Boil the wort 60 minutes, adding hops at the times indicated. Follow the remaining portion of the all-grain recipe.
