Brewday: Oatmeal Stout

So the stout for an upcoming wedding was brewed last week. It's a typical British Oatmeal Stout. I used some 200L Light Chocolate Malt instead of normal Chocolate Malt. Quaker Quick Oats. Modified the Miami water to get closer to London. Yeast was dry SA-04 British Ale yeast. A pretty flawless brewday until I accidentally pushed the Stopper Thermowell into the carboy. D'oh! That will be fun to retrieve. At least it was thoroughly sanitized...
