IPAeus III – an American “West Coast” IPA.
Brewed December 24, 2018. Bottled January 14, 2019.
6.3% ABV (OG 1.067 / FG 1.019)
- 6 kilo Pale Ale malt
- 500 grams CaraPils
- 500 grams Flaked Barley
- 30 grams Columbus hops
- 30 grams Cascade hops
- 30 grams Chinook hops
- 11 grams Safale US-05 ale yeast
- 185 grams demerara sugar
Equipment cleaned with bleach solution and sanitised with Iodophor solution. 23L filtered water heated up for the mash, with the grain bag added at 67°C for 60 minutes. Heat fluctuating just a few degrees throughout the process. Wort drained to about 21L, mash sparged with filtered tap water until approx 26L wort was put up to boil. Columbus hops and 15g of the Cascade hops added 35 minutes after boilpoint for 25 minutes, factoring time conversion for the use of the no-chill method. At flameout the remaining 15g of Cascade and Chinook hops were added to the pot. The approx 24L of wort was then decanted into the fermentation bucket directly, with a cork in place of the airlock to prevent air contamination. The following evening Safale US-05 yeast packet added to the brew with OG 1.067. Fermentation bucket placed in fermentation refrigerator, the temp fluctuating from 13-15°C for the first few days. Then, with the fridge failing, the brew sat for 30 or so hours at approx 25°C and then dropped back down to 14-18°C, rarely rising above that temperature. Checked 13 days into brew: SG 1.019. Checked 15 days into brew: FG 1.019 = 6.3% ABV. Bottled 19 days into brew into Iodophor solution-sanitised 330ml and 500ml bottles primed with 185 grams demerara sugar.
Yield: 20.67L (56 x 330ml, 4 x 500ml bottles)
