Notes

Won first place at the SMASH (Southern Marylanders Always Serving Homebrew) 4th Annual Brewers Challenge event!

I goofed and should've pitched two packets of yeast at the beginning. I pitched a second packet about halfway through fermentation after it slowed, and also added some Amylo 300. Pitching two packs at the beginning would've sufficed.
