The Naughty Dog

Petra and Gwil opened a roastery in October 2018. They wanted to move on, learn new things and deepen their coffee knowledge which they pass on coffee courses. The opportunity to influence the taste not only by preparing coffee, but also by roasting attracted them incredibly. Scott Rao, who helped them a lot in their early days and taught Gwilym roasting.They named the roastery The naughty dog because they have two naughty dachshunds that accompany them everywhere. And also because they wanted a cheerful, playful and original name.
