What beer colour actually tells you, and what it does not

May 12, 2025

The most confident wrong assumption in beer

Hand somebody a dark beer and watch what happens. They brace. They expect it to be strong, heavy, bitter and filling, and most of the time it's none of those things, and the same person will happily drink a pale beer that's two percent stronger without thinking twice about it.

Colour is the first thing you see and your brain treats it as a summary of the whole beer, which it isn't. It's worth knowing what it does report, because once you know, choosing a kit gets a lot easier.

What colour genuinely reports

Colour in beer comes almost entirely from how far the malt was kilned. Barley gets soaked and sprouted, then dried with heat, and the more heat and the longer it's applied, the darker the grain and the more the flavour shifts from bready toward biscuit, toffee, coffee and eventually burnt toast.

So a dark beer is telling you one honest thing: some of its malt was roasted hard, and you're likely to taste roast, chocolate or coffee notes as a result. That's the whole message. Everything else people read into it is invented.

What it doesn't report

Strength. Alcohol comes from how much fermentable sugar was there and how far the yeast took it, and colour has nothing to do with either. Plenty of stouts sit under 5 percent while plenty of pale ales sit above it.
Body. How thick a beer feels comes from unfermentable dextrins and protein, and a dark beer can be thin as water.
Bitterness. Hop bitterness is separate. Dark beers often read bitter, but that's roast bitterness from the grain, which is a different taste sitting in a different part of the mouth.
Calories or how filling it is. This follows strength and residual sugar, not colour.

The numbers on the tin, and why they look mad

Kit tins often print a colour figure in EBC, which is the European scale. Imported ones sometimes use SRM, which is the American one. Both measure the same thing, which is how much light a standard sample absorbs, and roughly speaking EBC is about twice SRM.

The scale is far from linear as it climbs, so a pale lager might sit around 8 EBC, an amber ale somewhere in the 20s to 30s, and a stout will run past 100 and keep going. Past about 80 your eye can't tell the difference anyway, because it's all just black in the glass and only the edge of the pour shows any colour. That's why a very large EBC number on a dark tin doesn't mean what it looks like it means.

Why this matters when you're choosing a kit

If you've been avoiding the dark end of the shelf because you think it's heavy going, you've been choosing on the wrong axis. There's a whole set of flavours sitting there that has nothing to do with how much beer you can drink.

And if you've been choosing pale because you want something light to drink on a hot day, check the strength figure instead, because that's the number that decides how the afternoon goes.

The middle of the range is where most people land once they've stopped choosing by appearance. An amber has enough roasted malt to give it toffee and biscuit character while staying entirely drinkable, and that is the reason people keep coming back to it after they've been round the houses.
