Scaled down to a 2 gallon recipe for testing the recipe. The original recipe calls for 5.5 gallons.
Add hops per the 60 minute boil schedule.
Once the boil is over, put your kettle to cool down to 67 degrees. 20 minutes after the cool down started (and most likely has ended) move the work to your primary fermenter, then add the cascade and gently swirl back and forth.
After several minutes, pitch your yeast and cap with your airlock.
After 8 days (or once fermentation has ended for you) add the Cascade Dry hops directly into your primary fermenter (or if you have a secondary fermenter, add there), and swirl gently back and forth for about 2 minutes, then place the airlock back on and let sit for ~7 days for best results.
