The grain bill for this beer changed a little to reflect what I perceived as a flaw in the last version - too much rummy raisiny flavour from the heavy dose of dark crystal. I dropped the total crystal bill by a small amount, and subbed half of that total for Simpsons Light Crystal. Another change was a lighter dose of early hops and a heavier dose of late hops. Since the beer is no chilled, even the late hops have a significant effect on bitterness, so pushing more of the hops to later on should give more hop character without changing the bitterness level.
I also changed the yeast, though I didn't really have a very good reason to do that, the yeast character in the previous version was actually a highlight. However I had a vial of White Labs Bedford Ale yeast platinum that I was really keen to use, so I decided to try it out on this beer. All but 15ml of the vial was pitched to a 1L starter and pitched at high krausen to the main batch.
