Hey guys - This past weekend I brewed the pumpkin ale recipe out of the most recent Zymurgy magazine. It’s a pretty big beer, with an OG target of 1.070 (12.625 lb of grain, 3 lb of pumpkin, 1 lb of maple syrup, 1 lb of honey). I was disappointed to see my OG to come in around 1.064… that’s the largest shortfall I’ve had.
Perhaps not so coincidentally, this was also my first multi-step mash. I hit the 120 protein rest, hit the 154 sacch rest, but came up short on the 168 mash out (hit about 163). With such a massive grain bill and mashing in a cooler, I had to start with a THICK grain/water ratio of 1 to 1. The 10 gallon cooler just couldn’t handle the volume of boiling water required to hit 168.
Feedback on 1064 vs. a goal of 1070? Is this shortfall massive? Have you all missed targets by that much and still made good beer?
Possible sources of shortfall, other than too much water.
A.Too thick of a mash at protein rest (1 to 1 ratio)?
B. Not hot enough on the mash out?
C. Ambiguity of recipe composition? For example, did my lb of honey have the same amount of sugar as the author’s? Same amount of sugar in my pumpkin as author’s pumpkin?
Thanks in advance for your feedback. Cheers!
