Kaffeemodul in Josefstadt is, by its own account, the smallest coffee shop in Vienna, and its rule is short: “Wir machen Kaffee. Alles andere sollen andere machen.” We make coffee, everything else others should make. The bar serves espresso with or without milk and filter coffee, and sells beans and brewing gear. The team includes Valentin, the Austrian Brewers Cup champion of 2016, and Boris, the Austrian Cup Tasting champion of 2016 and fourth at that year’s World Cup Tasting Championship. Kaffeemodul holds workshops on brewing, tasting and latte art for professionals and home baristas and brings a mobile bar to private parties and events.

The coffee comes from nomi coffee, Kaffeemodul’s own roastery in Simmering, and all of nomi’s coffees can be bought at the bar, with a changing selection to taste. nomi develops a roast profile for each coffee, roasting and cupping until the cup tastes the way it wants. It buys only from small, specialised importers such as The Coffee Quest, Nordic Approach and Falcon, and it lists the FOB price, the price paid in the country of origin, for every green coffee, with a minimum set above the Fair Trade price.

Several coffees come as both a filter roast and an espresso roast. The list includes a natural from Esayas Beriso in Guji, a Kenyan Kamathura lot from Embu, an anaerobic Guji Megadu that works for both, a Peach Geisha from Los Patios in Huila and Kapazunder, a blend in the Italian style with a quarter robusta.
