Description:

Adapted from 'Finkel & Garf Oatmeal Milk Stout' in the September/October 2016 Zymurgy magazine (original recipe found on page 24). This was a difficult recipe to convert using anywhere close to the original amounts of extract/malts and still achieving a comparable OG and SRM. The original recipe has an OG of 1.070 and SRM of 38. If a mash is conducted for 60-90 minutes to allow full conversion the OG may be within the realm of possibilities. Most partial mash recipes only require a short steeping of 20-30 minutes. Obviously a full mash of the grain bill will greatly benefit any beer, so that I leave that decision to anyone brewing this recipe. The more difficult task was achieving the SRM of the original recipe. The gluten free substitutes for chocolate and roast barley malts are not nearly as dark of a roast. Doubling the dark roasted malt additions still didn't come close to the SRM of the original recipe. So I decided to add 1 LB of D-180 Belgian Candi Syrup instead. It may be worth increasing the dark roasted malts in combination with the candi syrup, although, more than 24 OZ of the Gas Hog Rice Malt may impart noticeable bitter notes to the beer. The last obstacle is substituting the honey malt from the original recipe. Honey malt is unique even among conventional malts. CaraMillet seemed to be the best GF option, although, it is not recommended to add more than what the recipe calls for or a sweet aftertaste may impart onto the beer.
