## Notes

The brew crew wanted to try an oatmeal stout. The Pierson's Porter recipe was reconfigured to make this recipe. The changes are lower IBUs, medium crystal malt, and partial-mash for the oatmeal.

The oatmeal used was the typical Quaker oats used for breakfast cereal. These were boiled prior to the mash. A problem was that it cooled, then formed a thick, jello-like mass. Ugh. The mash temperature was too low due to adding this cooled oatmeal. This was fixed by boiling a small part of the mash (decoction), then returning it to the main mash. It wasn't a perfect process, but it turned out well.
