Grumkins and Snarks Oatmeal Stout
Brewed: 01/08/2023 Kegged: 01/16/2023
Late in 2022, I looked through the 2021 version of the BJCP Guidelines and discovered that I'd never really brewed any beer in three of the Categories. ![grumkin.jpg](/Images/grumkin.jpg)
This included the 16. Dark British Beer Category.
I felt like I had to rectify this situation.
Of the beers in the 16. Dark British Beer Category, the one that most interested me to brew was 16B. Oatmeal Stout, and I went ahead and designed a recipe.
A dark, roasty, full-bodied stout with enough sweetness to support the oat backbone. Enough hop bitterness to balance out the malt sweetness.
I included a significant amount of both malted and flaked oats, and earthy Fuggles hops towards the end of the boil to give a little more depth of character.
To read more about the Oatmeal Stout Style of beer, check out it's page on BJCP.
Originally, I thought I'd brew it in time to be drinking this before the New Year, but I ended up not brewing it until January.
Note, I will be brewing something in the other two categories early in 2023. Stay tuned for those on Sheppy's Blog: BJCP Goal.
The name " Grumkins and Snarks" refers to mythical creatures that are mentioned in Game of Thrones. I don't remember adding these to the potential beer names list, so I don't know if I got the name from one of the books or the shows, but when thinking of names for this beer, "Grumkins and Snarks" jumped out at me from the list.
I think the name is pretty cool, and it seems to fit well with a dark beer.
Yum!
