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.

Coffee trainings

How is coffee grown, where does it grow, how is it processed or roasted? Howto prepare it at home or in a cafe? We teach this and many other interesting things and skills at our coffee training courses in Jílové. Petra opened the training center in 2008. She trained a number of well-known baristas, but alsoa lot of home enthusiasts. Together with Gwilym, they devoted themselves to thecourses for many years. Now they spend more time in the roastery, which is why Šárka and Hanka help them. They are in charge of running the training center and conduct several trainings per week. So don't hesitate and join us on the coffee journey from the plantation to the cup.
