Tips

1
Small amounts of dark malt have a big impact. 0.5 lb of chocolate malt can push a pale beer into amber territory.
2
Actual color may differ from predicted due to boil intensity and oxidation

Open formula

MCU = (Grain Lbs × Lovibond) / Gallons
SRM = 1.4922 × MCU^0.6859

Calculates Malt Color Units then converts to SRM using the Morey equation.
