The subject of paying for green coffee is inherently complicated. While the amount paid is very important, the payment terms and type of contract negotiated during the purchase are also...

We roast to tight tolerances, with no more than 1° deviation from target temperatures. During the roast, we keep an especially close eye on rate of rise (RoR)- or the rate at which the bean temperature is increasing. This derevation gives us a much closer look at what's happening to the coffee during development. Below you'll find our most recently roasted batch of Colombia Letty Bermudez Gesha Thermal Shock.

We believe that quality is more than just flavor— it’s trust, integrity, and a relentless pursuit of excellence. That’s why we take extra steps to ensure that every cup of coffee you brew meets the highest standards of purity and safety.

Mold-Free

Mycotoxins

We recently subjected our coffees to rigorous third-party testing for mold and the mycotoxins they can produce—harmful compounds that may develop when certain molds grow on coffee beans. The results couldn’t be clearer: our coffee is 100% mold-free.

Lead-Free

Heavy Metals

We recently subjected our coffees to rigorous third-party testing for heavy metals—including Cadmium, Lead, and Mercury to ensure that every cup meets stringent safety benchmarks. We employ AOAC Method 2015.01, a gold-standard analytical technique in food safety with a detection limit in the parts per billion.

In Process

Our Facility

We adhere to strict food safety standards, including compliance with the Arkansas Department of Health Coffee and Tea Manufacturing Permit, GMP, and our Food Safety Plan. We ensure quality and safety through rigorous sourcing, processing, and sanitation protocols to deliver the highest standard of coffee to our customers.
