Roast porter

(1/3) > >>

I'm a huge fan of Otter Creek Stovepipe Porter, and I want to brew something similar for a winter session beer. The beer has a huge roasted flavor, a nice hoppiness but still goes down real easy. They have a lot of info (ingredients, IBU's & ABV) on their website, so I figured I'd take a first pass at cloning it.

This is my first time designing a recipe that uses this much roasted malt, so if anyone has feedback I'll take it.

I just did a porter yesterday. I wanted to use black patent for the roasty flavor. I accidentally used black roasted barley instead. I keep reading that black roasted barley imparts more of a coffee flavor where black patent imparts a good roasty flavor. I went ahead and threw that in too. We shall see how it comes out. My recipe was the following:

I accidentally added black roasted barley instead of black patent. After much thought I decided to add my black patent as well. I really wanted a roasty tasting porter. As a result this porter is too dark for the style. Fortunately I am not entering it in a contest so if it tastes good I will be happy.

I can't imagine anyone losing points for a porter being too dark, many of the classic styles in the guidelines are black and it is hard to differentiate the SRM of dark beers without diluting them.  I wouldn't worry about it at all.  Granted, you're not entering it in a competition so it's not important, but I wouldn't let it stop you if it turns out to be great.

I also don't think that 4oz of each (RB and BP) will really put the roast high enough to be out of style. In 5 gallons, I am usually between 8-12oz of roast malt in my robust porters.

I bottled this today. I tasted a sample and I am very pleased with the flavor.
