Beer Colours Explained

Quick Summary

Beer colour comes from malt, not strength. Lighter beers use lightly kilned malts, while darker beers use roasted malts. Colour affects flavour, but it does not determine alcohol content or bitterness.

Key Takeaways

• Beer colour is created by the type and roast level of malt.
• Darker beer does not automatically mean stronger beer.
• Colour influences flavour, especially roasted and caramel notes.
• The SRM scale measures beer colour.
• Many pale beers are stronger than dark beers.

Why Does Beer Have Different Colours?

Beer can range from pale straw yellow to deep black. That colour comes primarily from malted grains used during brewing.

When barley is malted and kilned, the level of heat applied affects colour:

• Light kilning produces pale malts.
• Moderate kilning produces amber and caramel malts.
• Heavy roasting produces dark malts.

The darker the roast, the darker the beer.

This process is similar to coffee roasting. Light roast coffee and dark roast coffee come from the same bean, but roasting changes colour and flavour.

What Is the SRM Scale?

Beer colour is measured using the SRM scale (Standard Reference Method).

Here is a simplified breakdown:

SRM Range	Colour	Examples
2–4	Pale straw to light gold	Light lagers, cream ales
5–9	Golden to amber	Blonde ales, pale ales
10–19	Copper to brown	Amber ales, some Scotch ales
20–40+	Dark brown to black	Porters, stouts

SRM measures colour intensity only. It does not measure alcohol, flavour intensity, or bitterness.

Does Darker Beer Mean Stronger Beer?

No.

Colour comes from malt roasting. Strength comes from fermentation and alcohol production.

A pale double IPA can reach 8% or 9% ABV.
A dark porter might sit comfortably at 5%.

This misconception is common enough that it deserves its own explanation in Why Dark Beers Are Not Always Strong.

Colour and alcohol are separate variables.

How Colour Affects Flavour

While colour does not determine strength, it does influence flavour.

Pale Beers

• light grain
• cracker
• subtle sweetness
• crisp finish

Golden to Amber Beers

• biscuit
• light caramel
• honeyed malt
• balanced bitterness

Dark Beers

• chocolate
• coffee
• toast
• dark fruit
• molasses

The darker the malt roast, the more pronounced roasted or caramelized flavours become.

Beer Colour vs Bitterness

Colour does not determine bitterness.

Many dark beers are low in bitterness and smooth. Many pale beers, especially IPAs, are highly bitter.

Bitterness is primarily driven by hops, not colour. For a clear explanation of that relationship, see Why Some Beers Taste Bitter (and Others Don’t).

Beer Colour vs Smoothness

Darker beers can feel smooth because roasted malts create richness. But smoothness is about balance, not darkness.

A cream ale may be pale and very smooth. A heavily hopped pale ale may be lighter in colour but feel sharper.

If smoothness is your focus, What Makes a Beer Smooth? explains how bitterness, alcohol, and fermentation contribute to that perception.

Examples Across the Colour Spectrum

Looking at familiar Ontario craft styles helps illustrate the spectrum.

• MacLean’s County Cream Ale sits in the pale to golden range, delivering smooth malt and a crisp finish.
• MacLean’s Original Pale Ale falls in the golden to amber range, where balanced hops meet classic malt structure.
• MacLean’s Cherry Porter moves into the dark brown category, offering roasted depth without aggressive bitterness.
• MacLean’s Armchair Scotch Ale often appears deep amber to brown, leaning into malt richness and warmth.

Each beer shows how colour signals flavour character, not alcohol strength.

For broader provincial context, Ontario Craft Beer explores how these styles fit into the larger scene.

Why Pale Beer Dominates Globally

Pale lagers and lighter styles became globally dominant because lightly kilned malts were easier to produce consistently at scale.

Clear, golden beer became associated with refreshment and stability.

However, darker styles remain foundational to traditional brewing heritage.

Understanding colour gives context to how styles evolved.

Does Colour Affect Alcohol Content?

No direct relationship exists between colour and alcohol.

Alcohol depends on:

• fermentable sugar content
• yeast performance
• brewing design

A dark mild might be 4% ABV.
A pale imperial IPA might exceed 8%.

Always check ABV on the label if strength matters to you.

For strength categories and examples, refer to Strong Beer in Ontario.

Why Beer Colour Myths Persist

Humans associate darker colour with intensity.

Dark chocolate feels richer.
Dark roast coffee tastes stronger.

That visual logic carries into beer, even though brewing works differently.

Beer colour reflects malt roasting, not alcohol concentration.

How to Use Colour When Choosing Beer

Colour can be a helpful guide if you understand what it represents.

If you prefer:

• Crisp and refreshing → look for pale gold beers.
• Balanced and slightly malty → look for amber tones.
• Rich and roasted → look for dark brown to black beers.

Colour helps anticipate flavour direction, not strength.

Frequently Asked Questions

Does darker beer have more alcohol?

No. Alcohol content depends on fermentation, not colour.

Is light beer weaker than dark beer?

Not necessarily. Many pale beers have higher ABV than dark beers.

Why is stout black?

Stout uses heavily roasted malts, which create deep colour and roasted flavour.

Does colour affect bitterness?

No. Bitterness comes from hops, not malt colour.

Final Thoughts

Beer colour tells you about malt and flavour, not strength.

Understanding the relationship between malt roasting, flavour, and fermentation removes much of the confusion around beer styles.

Once colour is separated from strength and bitterness, choosing beer becomes simpler and more intuitive.
