When it comes to speciality coffee in Köln, Ernst Kaffeeröster is one of the city’s pioneers, having first opened in 2014 on Bonner Straße, in the new town south of the centre. In true German fashion, Ernst Kaffeeröster is both coffee shop and roaster, and you can still see the original roaster, a 5 kg Diedrich, behind the counter at Bonner Straße, although these days it’s only used to roast some of the single-origins. Instead, there’s a 20 kg roaster in a dedicated facility, which opened in 2016, while in April, a month before my visit, a second coffee shop was opened on Weyertal, near the university.
The original Ernst Kaffeeröster is a modest spot, offering a handful of tables inside, plus two more outside on the pavement, along with a solitary bench. The draw is the coffee, with a blend and single-origin on espresso, along with batch brew, AeroPress and Kalita Wave if you prefer filter coffee. The single-origin espresso changes every month, while for AeroPress and Kalita Wave, you can have any of Ernst Kaffeeröster’s filter coffees. There’s also tea, hot chocolate, various cold coffee options and, if you’re hungry, a selection of pastries, cakes, baguettes and granola.
