Guatemala El Guachipilin

Valentina and Diego spent years as baristas, tasting coffees from roaster after roaster, before deciding to close the circle and build something of their own. Nubra is a micro roastery in Madrid's Barrio de las Letras, where they roast and serve from a small, minimalist space equipped with a Slayer espresso machine. The offering typically features around 15 different coffees, more than many established operations, with a focus on experimental fermentations: anaerobic, carbonic maceration, double washed, special honeys. Every lot is a single origin micro lot with complete traceability, and the team only includes coffees that genuinely excite them in cupping. Their baristas explain fermentation processes with the attentiveness of sommeliers. Despite launching only recently, Nubra has already drawn attention from guides and specialty enthusiasts, building its reputation through word of mouth among baristas across Spain.
