I like a little higher ABV in my oatmeal stout and a 6-gallon scale. This recipe was adapted from "Extract Recipe: Darkside of the Malt Oatmeal Stout, Posted on October 30, 2014 By Briess Contributor" http://blog.brewingwithbriess.com/extract-recipe-darkside-of-the-malt-oatmeal-stout/. My goal was to push the ABV while attempting to retain the original balance and scale to a 6-gallon recipe. I used 10 lbs of Briess CBW® Traditional Dark Liquid Malt Extract.
Note that about 3/4 gallon was lost in the rack due to the large amount of sediment. Heavy on the bottom then lighter on the top. It was above the spigot on the 6.5 gallon bigmouth bubbler fermentors.
