I based my partial mash recipe off of this thread: http://www.homebrewtalk.com/f12/any-...s-info-160119/ But that particular thread is kind of ramshackle, so I am organizing my recipe here.
I'm telling you, this recipe is right on target. Put them side-by-side and I couldn't tell you which one is which - the taste, the color, the mouthfeel. If there's any difference, it's that my yeast is slightly more detectable in the aroma. And the recipe should be good, as the ingredients and proportions came straight from a brewer at Founder's. I simply organized it and converted it to partial mash. They call it a porter, but I found that it fits squarely in the BJCP American Stout category.
