English IPA
The original, and a genuinely different drink from its American descendant: earthy and floral rather than citric, with the malt still in the conversation and a much drier finish than the gravity suggests.

Brewed to English IPA, and all five computed figures land inside the published ranges for it.

Using English hops throughout. Swap in Cascade and you have brewed an ordinary American IPA that happens to have Maris Otter in it.
Fermentables
| Malt | Weight | Colour | Extract | Of grist |
|---|---|---|---|---|
| Maris Otter Trimmed from 5.2 kg. At 5.2 the beer computed to a finishing gravity of 1.016, outside the style, and outside its own claim to finish dry. | 4.80 kg | 3 L | 37 ppg | 90% |
| Crystal 40L | 0.30 kg | 40 L | 34 ppg | 6% |
| Table sugar Historically standard in English brewing and the reason a strong bitter finishes dry. | 0.25 kg | 0 L | 45 ppg | 5% |
Colour and extract are read from the malt reference, not typed into this recipe, so they are the same figures every other page on the site uses.

Alpha acid varies by crop year and lot, which is why it lives on the recipe rather than on the variety. Brew to the figure printed on your packet and the bitterness will move; the IBU calculator will tell you by how much.
Method
- 01Mash at 65C for 60 minutes.
- 02Boil 90 minutes, adding the sugar with 15 minutes left.
- 03Ferment at 19C with an English strain.
- 04Dry hop 40 g East Kent Goldings for four days, which is longer than an American IPA wants because the oils are less volatile.
- 05Package at a restrained 2.1 volumes.

Strike temperature assumes grain at 20C and priming assumes the beer peaked at 20C after fermentation. Recompute both for your own kitchen on the strike and priming calculators.

Take a gravity reading two days apart and only package when it has not moved. A beer bottled while still fermenting keeps fermenting in the bottle, and the sugar you prime with lands on top of whatever was left. At 2.1 volumes this one needs about 97 g of dextrose for the batch.
