Specialty coffee in Hamburg.

Green coffee has come through Hamburg for two centuries. The Speicherstadt's brick warehouses were built in the 1880s to hold it, a coffee exchange opened on the Sandtorkai in 1887, and the traders still sit there: the German coffee association on Steinhöft, the Neumann group's glass headquarters in the HafenCity, a 1896 merchant house with a cupping lab on Pickhuben. For most of that time the city itself drank what the big industrial roasters made from the beans on their way through.

The specialty scene arrived surprisingly late and then made up for it. Annika Taschinski and Thomas Kliefoth opened Elbgold in Winterhude in 2004 and moved into the old slaughterhouse complex in the Schanze in 2008, where a big hot-air roaster now runs and a spin-off called Plot imports green coffee for roasters across Europe. In 2010 Andreas "Pingo" Felsen and friends founded Quijote in Rothenburgsort as a collective that buys only from smallholder cooperatives and publishes every price in the chain, from the farm gate to its own margins. It was new for Germany.

Around those two poles the city filled in: Public Coffee, which started roasting on a houseboat on the Elbe; Playground in St. Pauli, run by a photographer; Less Political in the Schanze, which became Hermetic; CODOS, which grew from an espresso bar into a roastery with a kitchen in Ottensen; Nord Coast serving pourovers with brunch on the Deichstraße. Every March the national championships come to the Internorga fair.

Elbgold is the cornerstone: a large hot-air roaster in the Schanze, Arabica only, separate profiles for its espresso blends and its fruit-forward filters, five cafés across the city, and Plot Coffee importing green beans for others. Quijote is the conscience: a worker collective in Rothenburgsort that buys only from democratically run cooperatives, roasts on demand, publishes farm-gate and export prices next to its own costs, and runs the Coffee School Hamburg upstairs. Public Coffee roasts clean, Scandinavian-leaning profiles and pours them from the Neustadt to the Speicherstadt.

Playground roasts light in St. Pauli with skateboards on the wall. Hermetic roasts uncompromisingly light on Sternstraße. CODOS roasts behind glass in Ottensen with its own pastry kitchen and cafés as far as Hannover. Nord Coast pairs pourovers with brunch on the Deichstraße and in Eppendorf. Black Delight roasts in Bahrenfeld and pours in Eimsbüttel, with anaerobic Brazils and Colombians on the shelf. Coffee Unlimited keeps a long list, and Black Hat

Hamburg trades coffee by the harbour, roasts it in the old slaughterhouse and the industrial east, and drinks it in the Schanze and the villa quarters.

Flat whites and cappuccinos sell the most cups, with oat milk on every specialty bar, and V60 and Kalita are standard at the brew bars: Hermetic, Nord Coast, Elbgold Schanze, Black Delight. On the shelf, Colombia, Ethiopia and Brazil lead Hamburg's listed origins, washed leads the processes with natural behind it.

The roasts divide by house. Elbgold and Public keep chocolate-and-hazelnut espresso profiles, Neunbar and Dark Temptation, for the northern palate and go lighter only for filter. Hermetic, Playground and Leuchtfeuer roast light throughout. Quijote does both, Dantes Inferno on one side of the shelf and light African filters on the other. Hamburg's micro-roasters mostly keep separate espresso and filter profiles rather than omni-roasting. Decaf is single-origin and sugarcane- or water-processed, a Kenyan at Elbgold and Quijote, a Peruvian at Nord Coast. The live count stands at 12 decaf and 44 filter-friendly listings.

Hamburg's ladder runs from the everyday blends to Leuchtfeuer's Geshas, and Quijote will show you the maths behind its share of it. These numbers come from every Hamburg coffee currently listed with a price, not a sample we chose. The going rate today is €41 per kilogram, about €10 for a standard bag.

The ladder reads like this: espresso blends and washed Latin Americans around €36 per kilogram, washed East Africans and the first fermented lots from about €52 per kilogram, and the most expensive listing right now at €194 per kilogram. 139 coffees carry a price today. Most roasters sell online with subscriptions; Quijote sells almost entirely that way.
