Batch #13: McNerney’s Oatmeal Stout

I finally ventured into the wonderful world of stouts!

When drafting this recipe, I wanted to create a good base stout recipe that I could use to build upon for other variations moving forward (oak aging, imperial stouts, etc.). I went with an oatmeal stout, because I like the flavor and body the oats impart into the beer, and I wanted to maintain a bit of residual sweetness with the final product.

Taste Notes

Aroma (8 of 12) – Sweet, creamy malt aroma. Light notes of coffee. Roasted grain aroma low.

Appearance (3 of 3) – Very dark w/ deep copper edges. Near black, with persistent tan head.

Flavor (12 of 20) – Coffee flavor from the malt comes through in the beginning, and mellows quicky. Sweetness comes through, but finishes with a slightly salty aftertaste. This may be attributed to my home water softener… Medium to low carbonation.

Mouthfeel (4 of 5) – Creamy, smooth body. Medium-full substance.

Overall Impression (7 of 10) – Overall very good. Missing roasted malt character, and would like to emphasize oats more by modifying water profile.

Total score: 34 of 50

Next time my goals will be to (1) improve the water profile, (2) use a bit more roasted barley, (3) use golden oats, rather than standard rolled oats, (4) use a British ale yeast, likely S-04, and (5) increase the O.G. slightly for greater body and ABV.

Competition Entry

I entered this beer in the 2014 Hogtown Brewoff and received a score of 30.5 (link to scoresheet).

Here are the highlights…

Aroma (6.5 of 12) – Both judges noted fruity esters and low roasted character.

Appearance (2 of 3) – Dark with good clarity, and good head retention. All positive comments — not sure why I was dinged a point…

Flavor (12.5 of 20) – Sweet malt and chocolate flavors the most noted. Some mention of hop flavor, and fruity yeast esters.

Mouthfeel (3 of 5) – Needs greater body, as well as more predominant oats character.

Overall Impression (6.5 of 10) – Presented as a reserved oatmeal stout. Needed more roast and oat character, greater body, and ABV.
