Notes

I should call this "Blown Gasket Oatmeal Stout." The airlock blew off while I was away for a week, and I returned to see a carboy, crusted with dried krausen. Regardless, it actually turned out well.

The final volume is low because I lost a good amount of water due to the seeping of 2.5 lbs of grain and oats. I didn't top off, preferring a stronger brew with fewer bottles. I plan to top off next time though.

I lost about half a gallon of the batch due to the blown fermentation, but it turned out pretty well! Excellent head retention and dark amber appearance. It didn't have quite as much chocolate or roasted flavor as expected. There is a significant nutty/toasted aftertaste that adds character. I plan to cut the crystal 60L from 8 to 5 oz or so, and add a source of chocolate and maybe lactose. I also plan to use a yeast with better attenuation. I was surprisingly pleased with this one, especially as it aged! Regardless, there is room for improvement.
