Distinctive profiles. Consistent by design.
Quercus Coffee turns oak-barrel maturation into a reliable green coffee category — not a one-off experiment. We develop, document and replicate sensory profiles for B2B buyers who need differentiation at volume.
The process comes from someone who built oak barrels and worked with Colombian distillers for 17 years. We did not buy the concept — we inherited it from the craft.

Founder · in memoriam
Guillermo Álvarez Arias spent decades building oak barrels by hand. He learned before anyone else that oak does not merely contain — it transforms.
Guillermo Álvarez Arias — founder and origin of the Quercus process. His craft is in every barrel.
Colombian origin
We source exclusively from Colombian regions whose cup characteristics complement controlled wood contact.
Specialization
Barrel maturation is our entire production line — not a side project. Every cask, schedule and protocol is built around it.
Sensory development
Our cupping team locks each profile to a defined target and refines it harvest after harvest.
Sustained production scale
20,000+ kg per year of barrel-aged green coffee, scheduled by allocation with B2B partners.
Quality control
Every batch is physically graded and cupped against the locked profile before release.
B2B reliability
Allocation-based production, export-ready documentation and predictable lead times.
