Capucas cooperative — five years on, here’s what changed

We started buying from the Capucas cooperative in Marcala, Honduras in 2019 — 78 farmers, 240 hectares between them, mostly washed Catuaí. We’ve been back four times. The infrastructure is different. The farmers’ income is different. Here’s the longitudinal report.

Why fresh matters: a 12-week shelf-life experiment

We measured aroma compounds in the same blend at week 1, week 4, week 8, and week 12. The drop-off is steeper than even we expected.

The annual report. Audited figures, including what we wish were different.

Every January we publish a public sustainability report. Direct-trade premiums paid (in dollars, by farm). Carbon offset purchases (Pachama-verified). Packaging waste avoided vs. the typical specialty-roaster baseline. Water + energy use at the roastery, year-over-year.

What’s in the 2025 report: $184,000 in direct-trade premiums above C-market. 412 metric tons of CO₂e offset. Compostable packaging across 100% of bags shipped. Plus a frank section on what’s still bad — shipping carbon scales with subscriber growth, and we haven’t figured that one out yet.
