We use a large percentage of specialty grains in this oneā¦ try about 10% Chocolate Malt, 7% Munich, 5% Carapils, and 3% Crystal Dark. I also throw in a little bit of Black Malt for a slightly burnt character. Mash in around 155 degrees and target an OG between 17 and 18 Plato. We use Nugget hops for bittering and Willamette and Crystal for flavor/finishing hops, targeting 45 IBUs. Ferment with an American yeast and it should terminate between 5 and 6 Plato, leaving you with 6.5% ABV and a full bodied robust Porter. Good luck, hope this helps.
