Brew beer colour estimate calculator

Calculate malt colour units and morey estimated SRM with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use malt colour units and morey estimated SRM to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Malt colour units (MCU)

MCU=sum pounds×Lovibond/gallons; Morey SRM=1.4922 MCU^.6859.

Morey estimated SRM

MCU=sum pounds×Lovibond/gallons; Morey SRM=1.4922 MCU^.6859.

Symbols and units
a
Ingredient masses (pounds)
b
Ingredient colour ratings (degrees Lovibond)
c
Batch volume (US gallons)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Empirical Morey color estimate, not measured optical absorbance. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Empirical Morey color estimate, not measured optical absorbance.
