Steep the crushed malts in 4.75 L of water at 70°C for 30 minutes.
Remove the grains from the wort.
Add the first hop addition at the beginning of the boil primarily as a foam inhibitor.
Add your malt extracts and Irish moss for the last 10 minutes.
Turn off your burner and remove your pot from your heat source.
Now add Cascade hops, and stir to mix in.
After about 3 to 4 minutes, begin using your wort chiller to drop the temperature of the wort to pitching temperature.
This addition is a bit tricky, but the goal is to have the large amount of hops in your beer for about 5 minutes after the beer has finished boiling, but prior to cooling below around 65°C.
This extracts a small amount of hop bitterness, and a large amount of hop flavour.
When you have cooled your beer to about 26°C, you can strain the beer into your fermenter.
Aerate your beer and pitch your yeast.
Ferment at 20-21°C to help hold the aromatics in the beer.
When fermentation is complete, rack your beer off the trub, and add the remaining “dry hop” addition of 50g of Willamette and allow the beer to absorb the dry hop flavors for about 4 days.
Then bottle or keg as you normally would.
