Mellow Coffee Roasters
Rotterdam, Netherlands
Founded by four friends — Vicky, Michael, Andy and Min — with backgrounds spanning law, medicine, economics and media, Mellow Coffee Roasters set out to be "yet another coffee roaster in the Netherlands" with a twist: celebrating Asian coffee origins they feel are underappreciated in Europe, alongside microlots from Latin America and Africa. The team roasts on ROEST equipment out of Rotterdam's Schiehaven and has placed in Dutch national competitions, including 1st at the Dutch Cup Tasters and 6th at the Dutch Barista Championship.
