Based on all the comments here I decided I had to try this recipe out! Unfortunately, I went down to my LHBS and they didn't have most of the British grains (which is to be expected?). Luckily, they recommended good substitutions and I was able to get 2/5 called for malts. I grabbed Magnum hops and WLP013 London Ale yeast and headed home also with my new Blichmann burner — finally got my own!
Everything went according to plan and after chilling the wort I pulled up a sample in my wine thief and the O.G. was spot on at 1.036. I threw the yeast starter in that I began ~36 hours before and later tonight it's already humming along at a nice fermentation.
I should mention that I pulled the airlock off and gave it a smell... absolutely amazing smell of molasses. Anyone else get that on theirs?
Thanks again for the recipe flyangler18!
