Color Conversion

Convert beer color values between SRM, EBC, and Lovibond scales.

The Color Conversion tool converts beer color measurements between SRM, EBC, and Lovibond scales.

How to Use

1. Enter a value in any color unit field

2. View instant conversions - All other units update automatically

3. Visual color preview shows approximate beer color

4. The tool remembers your last entered value

Beer Color Scales

SRM (Standard Reference Method)

• Used primarily in North America

• Range: 1-40+ for most beers

• Based on light absorbance at 430nm

EBC (European Brewery Convention)

• Used in Europe and many other regions

• Range: 2-80+ for most beers

• EBC ≈ SRM × 1.97

Lovibond

• Older system, still used for malt

• Visual comparison method

• Similar scale to SRM

Color Ranges by Style

Light Beers (2-6 SRM)

• Pilsner: 2-4 SRM

• Light Lager: 2-3 SRM

• Wheat Beer: 3-6 SRM

• Blonde Ale: 3-6 SRM

Amber Beers (6-15 SRM)

• Pale Ale: 5-10 SRM

• IPA: 6-14 SRM

• Amber Ale: 10-17 SRM

• Märzen: 8-17 SRM

Dark Beers (15-40+ SRM)

• Brown Ale: 18-35 SRM

• Porter: 20-30 SRM

• Stout: 30-40+ SRM

• Imperial Stout: 30-40+ SRM

Factors Affecting Beer Color

Ingredients

• Base Malts: 1.5-4 L

• Crystal Malts: 10-120 L

• Roasted Malts: 300-600 L

• Specialty Malts: Wide range

Process Variables

• Boil Time: Longer = darker

• pH: Higher = darker

• Oxidation: Darkens over time

• Caramelization: From kettle heat

Measuring Beer Color

Laboratory Method

• Spectrophotometer at 430nm

• 1cm path length

• Dilute if needed

• Most accurate method

Visual Comparison

• Compare to color charts

• Use proper lighting

• White background

• Less accurate but practical

Digital Tools

• Phone apps available

• Photo analysis

• Reasonable estimates

• Convenient for homebrewers

Practical Applications

Recipe Design

• Target specific color

• Balance malt bill

• Predict final appearance

• Match style guidelines

Quality Control

• Monitor batch consistency

• Track color changes

• Identify process issues

• Compare to standards

Competition

• Meet style requirements

• Judge expectations

• Visual appeal

• Score optimization

Color Perception

Lighting Effects

• Daylight: Most accurate

• Incandescent: Appears redder

• Fluorescent: May shift hue

• LED: Varies by type

Glass and Volume

• Appears lighter in thin layers

• Darker in full pint glass

• Sample in consistent vessel

• Standard is 1cm path

Tips for Color Control

1. Accurate Measurements: Weigh malts precisely

2. Fresh Ingredients: Old malt may darken

3. pH Control: Monitor and adjust

4. Consistent Process: Same boil time/vigor

5. Avoid Oxidation: Minimize post-fermentation

Troubleshooting

Darker than Expected

• Check boil time and pH

• Avoid scorching

Lighter than Expected

• Verify extraction efficiency

• Check malt specifications

Using with Recipe Design

• Convert between scales when following recipes

• Check if your beer color matches style guidelines

• The tool remembers your last entered values

• Use for consistent color targeting across batches
