The pale, crisp, delicately fruity ale from Cologne, Germany — warm-fermented like an ale but cold-conditioned like a lager, producing a beer that splits the difference in character. Straw-gold, subtly hoppy, and notably dry. Typically 4.4–5.2% ABV. Protected origin: only beers brewed within ~50km of Cologne may legally be labeled ‘Kölsch’.

Origin
Cologne has a long continuous brewing tradition — the Kölner Brauer-Kooperation (Cologne Brewers’ Cooperation) was founded in 1396 and still exists in modern form as the Kölner Brauerei-Verband. Bottom-fermented beer began making inroads in the Cologne region in the early 17th century; the town council responded in 1603 by requiring local brewers to swear an oath to continue brewing with top-fermenting yeast, and tried again in 1676 and 1698 to forbid the sale of bottom-fermented beer within the city walls. By the mid-18th century Cologne brewers had adopted a hybrid approach of their own — top fermentation followed by cold conditioning — and in the late 1800s, with pale Bohemian lager pressing on local markets, they sharpened that approach into a golden, hoppy top-fermented beer that could compete head-to-head with pilsner while retaining an ale-yeast character.
The name “Kölsch” was first applied to the modern style in 1918, describing a beer that the Sünner brewery had been producing since 1906 — developed from the older, cloudier Wieß. Cologne’s brewing industry was devastated by World War II (only two breweries survived the war), then rebuilt in the post-war decades. In March 1986, twenty-four Cologne-area brewers signed the Kölsch-Konvention, which defined Kölsch as “a light-colored, highly fermented, strongly hopped, bright, top-fermented Vollbier,” specified the traditional 0.2-liter cylindrical “Stange” glass for service, and — crucially — restricted the name to breweries in and immediately around Cologne. Kölsch received Protected Geographical Indication status from the European Union in 1997, placing it alongside Champagne and Chianti as a legally protected regional specialty; only beers brewed within roughly 50 km of Cologne may use the name.
Notes
Kölsch is traditionally served in 0.2-liter cylindrical “Stange” glasses carried to tables in round wooden racks called Kränze; the aproned waiters known as Köbes refill empty glasses without prompting until the drinker places a coaster on top to signal they’re done. The crosstown rivalry with Düsseldorf’s altbier — the copper-colored warm-fermented-cold-conditioned ale 40 km up the Rhine — is a running local joke; both styles use the same hybrid brewing logic applied to different malt and color targets.
