Notes

First Place - Amber/Brown Ales

No sparge method may have resulted in a lower efficiency

pH 5.5 (a tad high)

2L starter, decanted (a hint of diaceytal is present due to the extremely quick fermentation. Consider reducing the starter size to 1-1.5L and pitching at 54F)

Fermentation Schedule
Day 1-3: 58F (fermentation started to slow after 72 hours)
Day 4: 60F
Day 5: 62F
Day 6: 64F
Day 7: 66F
Day 8-14: 68F
