The Rimini result sits alongside a first place at the SCAE Roasting Challenge Turkey. Petra roasts on a 12-kilogram Probat with modified burners, to a Scandinavian profile. Kaan Bergsen left mixology for coffee, working at Stumptown and Toby's Estate in New York, before founding Petra with Can Duna in 2013. The company imports its coffee directly rather than through Turkish importers.
The Gayrettepe shop had Istanbul's first La Marzocco Strada, with a Mahlkönig EK43 for filter and Anfim grinders for espresso. Petra has been the Istanbul distributor for Anfim, Chemex, Baratza, and KeepCup.
