Brew #29: India Pale Ale

Today I brewed another Northern Brewer recipe, this one is an India Pale Ale.

This time I tried a few new things. First, I used some software to manage my brew. I purchased the Beer Smith package. Very easy to use, and can even be run under Wine if you don't want to use a Windows machine. The software was especially helpful in doing the multi-stage infusion. It calculated the amount and temperature of water I would need for each step.

This enabled me to do a two stage infusion. The first was at 151 degrees, the second at 165 degrees. I undershot a little, because when I did the first stage, I didn't wait long before taking the temperature. It was 161 F, so I added 2 quarts of cold water. This dropped it considerably, so I'm thinking the temperature was okay after all, but just needed a minute to transfer the heat from the water to the grains.

Beersmith also generates an HTML brew sheet, so I'm going to paste that in here.
