Another Imperial IPA

November 23, 2010

On Saturday I whipped up another Imperial IPA. I was considering making my Simarillo IIPA again, but wanted to try something different. This one was a pretty simple grain bill and used no sugar. Instead of the Amarillo and Simcoe hop combination, I used Chinook with the Amarillo for most of the character with some Columbus in the aroma and Galena for bittering. I wanted a solid and clean bitterness with plenty of citrus and spice in the nose.

For this batch, because of the all the hops being used, I bumped the volume up half a gallon to account for hop absorption. 8 gallons were collected and boiled down to 7, then the hops plugged up the screen in the kettle just as I got 5 gallons into the fermenter. Just as I had planned, basically. Keeping as much of the sediment out of the fermenter as possible has become my goal recently.
