Ingredients for Rainy Day IPA
- 10 oz. 20° crystal malt
- 1 lb. 60° crystal malt
- 3 lbs. golden light dry malt extract
- 3 lbs. sparkling amber dry malt extract
- 2.1 oz. whole Cascade hops (bittering)
- 1 oz. Cascade hops pellets (5.4% alpha acid; second addition for bittering)
- 1 oz. Cascade hops pellets (5.4% alpha acid; aroma)
- 1054 American Ale Yeast (Wyeast brand "smack pack")
- I heated 2.5 gallons of tap water to 158°, and steeped the crystal malt for 30 minutes.
- I gently rinsed the malt (in its nylon steeping bag) with warm water, to bring the volume up to 3 gallons
- I heated the liquid up to boiling, and then turned off the heat. I added the dry malt extract, and stirred it until dissolved. Then, I turned the heat back on. No issues with boil-over! I'll have to try this procedure (rather than just adding the DME to boiling water) again. It probably results in a very slightly darker wort, but I think it's worth the reduction in hassle!
- Once the wort was back at boiling, I added the whole Cascade hops. I let it boil for around 18 minutes, before realizing I should add a few more hops in order to get to the desired bitterness. So, I then added an ounce of the hops pellets.
- After 55 minutes of boiling, I added 1 oz. more of Cascade hops (for aroma), and boiled this for 5 minutes more. Then, I chilled, decanted into the secondary fermenter, and topped it up to around 4.5 gallons with distilled water. Finally, I pitched the yeast.
- Starting gravity was 1.056, calculating out to 7 percent potential alcohol content. This will probably translate, when all is said and done, to about 5 percent alcohol content. The wort is a nice straw color. . .somewhere between amber and golden.
I found a very handy IBU calculator here. Assuming 6 pounds of DME in 3 gallons of water ([6 lbs * 43 points per pound]/3 gallons = 1.086 s.g. during the boil) and 5.4% alpha acids for all hops, the resulting black-box calculation showed an IBU yield of 108.4 for the 3 gallons. By the time this gets diluted out to 5 gallons, I would predict a specific gravity of 1.057 and an IBU of 72. My actual gravity (1.056) was a little higher because I only filled to about 4.5 - 4.75 gallons.
