SEYMOUR OATMEAL MOLASSES INDIA PORTER
A very stout porter containing oatmeal, toasted buckwheat, and molasses. Somewhat elevated hops and alcohol percentage in order to survive its long sea voyage to the enlisted soldiers; tastier and more complex than the pale stuff the officers drink. Yeah, I know I'm playing fast and loose with the adjuncts and historical facts...just no one tell Ron, cool?

BOIL for 60 min.
HOPS
.6 oz = 17 g, Chinook (USA), 13% AA, 60 min
2 oz = 57 g, Hallertau (Germany), 3% AA, 30 min
.2 oz = 5.7 g, Chinook (USA), 13% AA, at flame-out & steep 30 min before chill
.2 oz = 5.7 g, Progress (UK), 8% AA, at flame-out & steep 30 min before chill
.2 oz = 5.7 g, Challenger (UK), 6.3% AA, at flame-out & steep 30 min before chill
CHILL, then TRANSFER to fermentor, then AERATE, then PITCH yeast.
YEAST: Split into two batches, ferment at 72°F/22.2°C
1. Windsor (UK ale strain, product of Austria), 3.75 US gallons. After some serious Ditch-style-drill-powered-aeration, the yeast were visibly working within minutes, I sh!t you not.
2. Adnams dual-strain (UK), 3rd generation, which morphed to produce a very Belgian-y beer last time, 1.5 US gallons. Oddly, despite pitching a larger population this time, the yeast still exhibited a nerve-racking 48 hour lag-time. Indeed, it was infected and had to be dumped.
STATS considering a 72% mash efficiency and 80% apparent attenuation:
