1868 East India Pale Ale

(5 gallons/19 L, all-grain)
OG = 1.067 FG = 1.015 IBU = 100+ SRM = 6 ABV = 7.1%

Ingredients

14 lbs. (6.4 kg) Maris Otter pale ale malt
51 AAU UK Goldings hops (90 min.) (10.25 oz./0.29 kg at 5% alpha acids)
3 oz. (85 g) UK Goldings hops (dry hop)
White Labs WLP017 (Whitbread Ale) or Wyeast 1099 (Whitbread Ale) or Safale S-04 yeast
2⁄3 cup corn sugar (if priming)

Step by Step

Mash grains with hot water (1.2 qts./lb.) at 150–152 °F (66–67 °C) for 1 hour. Run off and sparge to collect about 6 gallons (23 L) of wort. Bring to a boil and add the bittering hops, boil 90 minutes. Cool to 65–70 °F (18–21 °C) and pitch with yeast, preferably two packs prepared previously as two 1-qt. (1-L) starters. Ferment 5 days, rack to secondary and add the dry hops in a sanitized weighted muslin bag. After 1–2 weeks rack to keg or bottle and prime or carbonate in the usual way. *This is a lot of hops, which will likely result in loss of wort in the residue when racked. I have used Goldings for this to follow the original as closely as possible. However, it is more practical to replace these with 29 AAU Progress hops (3.6 oz./102 g at 8% alpha acids).

Extract Version: Simply replace the pale malt in the recipe with 9.3 lbs. (4.2 kg) Maris Otter liquid malt extract. Boil for only 60 minutes — the shorter boil will not materially affect the actual IBU since the figure quoted above is merely a calculation and is probably higher than the actual solubility of iso-alpha-acids. As above, you may find it more practical to replace the Goldings bittering hops with 29 AAU Progress hops (3.6 oz./102 g at 8% alpha acids).
