Onyx Coffee Lab

California Finca 1890 Gesha

Grown in the coastal foothills of Santa Barbara County near Carpinteria, this Geisha varietal thrives in California's cool Pacific microclimate—a rare growing environment for specialty coffee. The beans are hand-picked at peak ripeness, then undergo 48-hour yeast fermentation before washing and slow drying, a process that concentrates clarity and complexity. The result is a refined cup that showcases how terroir and meticulous processing can elevate even an unexpected origin into something genuinely distinctive.
