Like Kölsch, altbier combines top fermentation with cold conditioning.

Altbier: Düsseldorf’s copper-coloured, cool-conditioned ale.
Altbier is top-fermented like an ale but matured cool, creating a clean, dry beer with toastier malt and firmer bitterness than Kölsch.
2
Malt is toastier
Munich-type malt can bring bread crust, toast and light nuttiness.
3
Bitterness is firmer
Traditional noble-type hops help create a dry, structured finish.
Why is it called “Alt”?
The name refers to the older top-fermentation method that remained important around Düsseldorf even as lager brewing spread across Germany.
How is it different from Kölsch?
Altbier is usually darker, toastier and more bitter. Kölsch is paler and more delicate, while both use ale fermentation followed by cold maturation.
Is altbier a dark lager?
No. The clean finish can feel lager-like, but the fermentation family is different. That makes altbier a good example of why colour and fermentation type should not be confused.
Why does Düsseldorf matter?
Traditional brewpubs and local serving culture kept the style alive as a regional identity rather than just a recipe.
