Xavier Nonnenmacher is a self taught roaster who founded Renart from the small Alsatian village of Hohengoeft, about thirty kilometers from Strasbourg, at 17 Rue Principale. The name draws from old French, where "renart" means fox, a nod to the cleverness and resourcefulness required to build a roastery from scratch. His talent was recognized nationally when he earned the title of French Roasting Vice Champion in 2019, a remarkable achievement for someone who developed his skills independently. Nonnenmacher launched the roastery during the pandemic, turning a period of uncertainty into an opportunity to pursue his passion for sourcing and roasting beans from small producers. His meticulous approach to each batch reflects both his competitive drive and his deep respect for the farmers behind every coffee he roasts.
