I brewed IPA today with a very familiar grain bill as a base and a couple of, I thought, minor tweaks.
Boil Size: 13.25 gal
Batch Size (fermenter): 11.00 gal
Estimated OG: 1.065 SG
Estimated Color: 6.9 SRM
Estimated IBU: 64.8 IBUs
Brewhouse Efficiency: 80.00 %
Est Mash Efficiency: 81.5 %
Boil Time: 62 Minutes
Measured MASH EFFICIENCY: 78%
Amt Name Type # %/IBU Volume
22 lbs Briess 2 Row (1.8 SRM) Grain 1 84.6 % 1.72 gal
2 lbs White Wheat Malt (Avangard) (2.0 SRM) Grain 2 7.7 % 0.16 gal
1 lbs 8.0 oz Caramel Malt - 40L (Briess) (40.0 SRM) Grain 3 5.8 % 0.12 gal
8.0 oz Acid Malt (3.0 SRM) Grain 4 1.9 % 0.04 gal
That’s the most wheat I’ve used in this grain bill and I’m also using half pound of acid malt rather than my usual lactic acid addition.
So do you guys see reduced mash efficiency when using wheat or acid malt? Shouldn’t Beersmith estimate based on expected yield of the grains anyway?
78% isn’t bad of course but that’s much lower than I usually get and that’s a crap ton of 2 row to get such a low efficiency.
