Mill the grains and dough-in targeting a mash thickness that will enable your system to achieve the necessary pre-boil volume and gravity. Hold the mash at 150 °F (66 °C) until enzymatic conversion is complete. Infuse the mash with near boiling water while stirring or with a recirculating mash system raise the temperature to mash out at 168 °F (76 °C). Sparge slowly with 170 °F (77 °C) water, collecting wort until the pre-boil kettle volume is around 6.5 gallons (25 L) and the gravity is 1.052 (12.9 °P).
The total wort boil time is 90 minutes. Add the bittering hops as soon as the wort starts boiling. With 30 minutes remaining in the boil, add the second hop additon. Add Irish moss or other kettle finings with15 minutes left in the boil. Add the remaining hop addition at 5 minutes. Chill the wort to 65 °F (18 °C) and aerate thoroughly. The proper pitch rate is 16 grams of properly rehydrated dry yeast, 2.3 packages of liquid yeast or 1 package of liquid yeast in a 2.7-liter starter.
Ferment at 65 °F (18 °C) until the yeast drops clear. Allow the lees to settle and the brew to mature without pressure for another two days after fermentation appears finished. Rack to a keg and force carbonate or rack to a bottling bucket, add priming sugar, and bottle. Target a carbonation level of 2.5 volumes.
FOR COCONUT:
Toast ~1lb of unsweetened, shredded coconut on parchment paper at 250 degrees until golden-brown. Broil at lowest temp if needed for final browning.
Fill hop-filter with coconut and add directly to cold keg. Flavour will start to become apparent within 24 hours, and slowly grow over time.
