The art of coffee roasting

Roasting is where the bean finds its flavor

We start with the green bean, not the roast

We start with the green bean, not the roast

Excellent roasted coffee is only possible with excellent green coffee. We work exclusively with traceable coffees from Hacienda Las Mercedes and allied producers in Antioquia, selected by density, moisture, and sensory profile.

  • Green coffee with 11-12% stable moisture
  • Traceability by farm, varietal, and process
  • Cupping prior to roast profile design
  • Milling and grading in our own facilities

Testimonials

Brands that already roast with us

Green Hills designed an espresso profile for us that differentiates us in every coffee shop we serve. Consistency between batches is what we value most.

We started with a toll manufacturing of 100 kg per month and today we are at 800 kg. Without Green Hills, we would not have been able to scale our brand so quickly.

The sensory report included with each lot helps us better sell the coffee to our end customers. It's real traceability, not marketing.
