Kaffeefabrik

Organic, roasted in Vienna, sold by the cup and the bag

Everything on the shelf here is bio and fair: organically grown, traded fairly or directly, and roasted in Vienna rather than bought in. That single rule has run the business since 2011 and it shapes the bar as much as the roastery. Orders stay close to the specialty essentials, espresso, cappuccino, flat white, oat cappuccino and batch brew, because the interest is in the bean rather than the syrup rack. The roast list covers espresso, filter, omniroast and decaf, and the same coffees go home whole bean or ground for portafilter, moka pot, Aeropress, filter or French press.

A bean list worth reading before you order

Bio Rutas del Inca Anaerob is the lot described in most detail: a washed anaerobic arabica microlot from Cajamarca in Peru, with fruit, red grape and brown sugar in the cup. Around it sits a long shelf, Bio Wayanad Anaerob ML, Bio Kusini, Bio Disco, Bio Alma, Bio Combrifol Honey, Bio Sidama, Mon Amour, Bio Seemann, Bio Populär, Bio Permata Gayo, Bio Fondo Paez, Bio Taramesa and Bio Schilicho, enough range that regulars buy by name rather than by roast level.

The rooms are small and the operation runs across more than one of them, with a coffee school attached, so a visit sits somewhere between a bar, a shop and a lesson. That is the useful thing to know: an espresso at the counter, a batch brew while you decide, and a bag under your arm on the way out is the normal sequence rather than a long sit-down.

Order the flat white, then buy beans

Start with the flat white for a clear read on the house roast in milk. Espresso is the shorter, more direct version of the same thing, the oat cappuccino covers dairy-free, and batch brew is the straightforward filter order when you want origin character without waiting on a hand pour.

Then let the shelf decide the rest. Rutas del Inca is the one to take if you want the most specific cup, and the wider range spans espresso, filter, omniroast and decaf with the grind set to whatever equipment is at home. There are homemade sweet things at the counter, vegan ones included, but they are a companion to the coffee rather than the reason to come. Service runs in English as readily as German, and the baristas will talk through the shelf if you ask.
