Brewed up a 2.5g batch of this a couple months back, bottle conditioned it in 750ml's.
The only thing I changed was to use Marris Otter as the base malt, and boy was I pleased with the decision to do so.
Just tonight I did a side by side with some friends of the real McCoy vs my batch with the MO.
I don't want to sound like a braggart, but mine was notably better. I really am starting to be convinced that higher quality base malts can contribute a huge difference in the end result.
Thanks for a great recipe.
