Specialty coffee, measured.

A worker-owned cooperative bridging high-tech roasting precision and the manual craft of specialty coffee. We replace guesswork with sensors, opacity with ledgers, and marketing with data.

The Three Pillars

Every decision — sourcing, hiring, pricing — is filtered through these.

01

Technical Precision

We treat roasting as a technical system. Real-time bean-probe and exhaust sensors log every batch. Profiles are repeatable to within tenths of a degree.

  • BEAN_PROBE±0.1°C
  • SAMPLES/SEC4 Hz
  • BATCH_LOGRETAINED
02

Financial Transparency

The Glass Box. We publish the full economic journey of every coffee — from farmgate price to our internal margin. An informed customer is a partner.

Radical Sustainability

Regenerative agriculture, high-efficiency roasting, plastic-free distribution. The environment is a stakeholder in our cooperative, not an externality.
