One of my favorite styles is a semi-sweet, smooth easy drinking Oatmeal Stout. This is my first attempt at formulating one of my own.
I kind of designed this grain bill from scratch and admit to not really knowing what I was doing when I threw this together. I knew the Oats (15%) would add a creamy mouthfeel. I was hoping to see some stronger coffee / chocolate flavors from both the Roasted Barley and Carafa I. The Special B I thought might add some caramel flavors.
|4lb 8oz||Maris Otter (UK)||3||66%|
An early addition of Nugget made up the bulk of the bittering with a late addition of EKG for flavoring.
|0.4oz||Nugget (US)||13.5%||FWH – 60 Minutes||Pellets|
|0.25oz||EKG||6.0%||Boil – 10 Minutes||Pellets|
I decided to go with a good malty British strain.
|WY1968 London ESB Ale||Wyeast||67-71%||64°F-72°F|
Like with the Tripel, I used Denver tap water with no modifications.
Fermenting & Packaging
The Oatmeal Stout was fermented in a primary for three weeks. It reached FG within 7 days. I normally would package after two weeks, but the stout got an extra week because I was lazy.
I packaged in 12oz bottles w/ half a pack of champagne yeast and enough table sugar to carbonate to 2.3vols.
I have a hard time determining what I think about this one. My palette isn’t necessarily all that refined and it seems every time I would pour this beer, I would get something different.
Aroma is very malty with a touch of roastedness. The flavor is definitely dominated by roasty and coffee flavors. Sweetness is about right, though sometimes it tastes way dryer than the last bottle I poured. Notes of raisins maybe? Some toffee maybe? Hop bitterness is right about where I wanted it. Mouthfeel is silky and creamy, as one would expect with 15% flaked oats. Appearance is dark, mostly opaque due to the darkness. Pours a nice tan colored creamy head.
In future revisions, I think I will add some medium crystal malt, like Caramel 60 or so, and replace some or all of the Special B to add more lighter caramel flavors. Also, I’ll probably eliminate the late addition of EKG, I don’t think it adds anything. Overall, I think this was a good beer, and a few minor tweaks could make it even better.
