I found a recipe for Fat Tire in the December 2010 BYO Magazine – a subscription is a must, this magazine is full of recipes and information – and put it through BrewTarget for a One Gallon batch to see how close the OG, FG, IBU, ABV and SRM matched the original – it was very close.
Here is the one gallon recipe. When I try it I will let you know if it is any good. If you try it, let us know.
1.725 lb Pale Malt
3.2 oz Munich
1.6 oz Victory
1.6 oz Crystal 80L
.08 oz Target (60 min)
.1 oz Willamette (10 min)
.1 oz Goldings (0 min)
WLP051 California Ale V Yeast (I am going to use Safale US-05)
Mash at 154 for 90 min. Ferment at 68.
