Spotted some Firestone Walker at the store and was inspired to use the rest of my flaked oats for a homebrew. 13C is the BJCP category for Oatmeal Stout and so far my beer falls within the stats.
I am using some East Kent Goldings for hopping and Maris Otter for the base malt. Unfortunately it wasn’t worth an hour of driving to get some British yeast, so I’ll use the US-05 that I’ve got.
Pretty easy to spot the missing ingredient!
