Mash:
15.5 lb Domestic 2-row malt (1.8-2L) (78.5%)
3.5 lb Weyermann Vienna malt (3-4L) (17.7%)
0.75 lb Crystal malt (40L) (3.8%)
Boil:
1 oz Centennial hops (9.2%) - added during boil, boiled 20 min [8.0 IBU]
1 oz Amarillo hops (8.2%) - added during boil, boiled 20 min [7.2 IBU]
1 Whirlfloc tablet (Irish moss) - added during boil, boiled 15 min
2 oz Centennial hops (9.2%) - added during boil, boiled 10 min [11.5 IBU]
2 oz Amarillo hops (8.2%) - added during boil, boiled 10 min [10.2 IBU]
Post-boil:
2 oz Centennial hops (9.2%) - added immediately after boil
2 oz Amarillo hops (8.2%) - added immediately after boil
Yeast:
Fermentis Safale US-05 dry yeast* (36g recommended or make an equivalent starter)
Dry hop:
2 oz Citra hops (11.1%) - added to fermenter near end of fermentation, steeped 3-5 days
Add 500mg potassium metabisulphite to 20 gallons water to remove chlorine / chloramine (if required).
Water treated with brewing salts to our Hoppy flavour profile: Ca=110, Mg=18, Na=16, Cl=50, SO4=275 (Basically Randy Mosher's ideal Pale Ale numbers with slightly less Sulphate). For more information on how to adjust your water, refer to our step by step Water Adjustment guide.
1.25 qt/lb mash thickness.
Single infusion mash at 152F for 90 mins.
Raise to 168F mashout temperature and hold for 10 mins.
~90 min fly sparge with ~5.6-5.8 pH water (measured at mash temperature). Collect 13.9 gallons.
Boil for 60 minutes, adding Whirlfloc and hops per schedule. Lid on after post-boil hops are added, start chilling immediately.
Pure oxygen aeration system with tank and diffusion stone
BUY NOWCool the wort quickly to 66F (we use a one-pass convoluted counterflow chiller to quickly lock in hop flavour and aroma) and transfer to fermenter.
Aerate or oxygenate the chilled wort to a level of 8-10 ppm dissolved oxygen. For more information refer to our Aerating / Oxygenating Wort guide.
Pitch yeast and ferment at 66-68F (wort temperature). We use modified stainless fermenting buckets in wine fridges.
Add dry hops once fermentation is nearing completion (i.e. 5 points from final gravity) and raise the temperature to 70-72F. In our case we simply turn off the fermenting fridges and allow the beer to naturally rise to room temperature. Steep hops for 3-5 days while fermentation finishes. Assume fermentation is done if the gravity does not change over ~3 days.
Before packaging you may optionally rack to a brite tank (we use 5 gallon glass carboys) that has been purged with CO2 to avoid oxygen pickup, add 1 tsp of unflavoured gelatin dissolved in a cup of hot distilled water per 5 gallons of beer, and allow to clear for 2-3 days. Gelatin may "round off" some hop flavour / aroma so we tend to skip this step with hop forward beers like this.
Package as you would normally. We rack to kegs that have first been purged with CO2, and then carbonate on the low side (around 2 volumes of CO2) to minimize carbonic bite and let the hop and malt flavours shine through. We chill the kegs to near freezing while carbonating at the same time in a 6-keg conditioning fridge. After ~1-2 weeks at serving pressure the kegs will be carbonated and ready to serve. Like all hop forward beers this IPA is best consumed fresh so feel free to raise the CO2 pressure temporarily to 30-40 PSI to carbonate fast over a 24 period, and then turn back down to serving pressure. Some hop bits will have invariably made their way into the keg during transfer so we use a Hop Stopper Keg Edition filter to ensure that hops do not clog the dip tube and/or end up in the glass. Force carbonating at high pressure and using a Hop Stopper filter allows us to serve this beer 24 hours after kegging. There's no need to wait a few days for any hop bits that made their way into the keg to first settle out.
