My Brother and I made a batch of Pumpkin beer for the holidays, this was our second batch. The last one we made we were a little low on the gravity, 10.5something as opposed to 10.60. We made a second batch using a little less grain and way more pumpkin, also we put about a pound of brown sugar in the first one and no sugar n the second.
This second one we figured to hit 10.50 or so, but in fact we got 10.32ish.
We did a step mash, 3.5 gal at 134 for 20 min, then an additional 6 gal at 154, same as the first batch, only different water volume last time but it was proportional.
Did a 60 min boil both times, and in the first batch we probably should have boiled for a little longer, which is probably why we didn't hit our gravity.
Anyway, we pitched the yeast figuring we could just make a session pumpkin to go with our stronger one.
Any ideas what might have gone wrong?
