We believe you deserve to know exactly what's in your cup. That's why every lot we source goes through third-party laboratory testing before it reaches you. We're proud to share the latest results for our Arabica Yellow Catuaí from Fazenda Santana in Serra Negra, São Paulo.
Testing was conducted by Cambium Analytica, an ISO/IEC 17025:2017 accredited lab based in Traverse City, Michigan. The certificate covers four panels: aflatoxins, two rounds of pesticide screening, and yeast & mold. Here's what they found:
Why Aflatoxins Matter
Aflatoxins are naturally occurring mold toxins produced by Aspergillus fungi. They're a real and well-documented concern in agricultural products — including coffee — especially in regions with high humidity or inadequate post-harvest drying. Ochratoxin A, another mycotoxin we test for, has been found in coffee grown and processed under sub-optimal conditions worldwide.
The World Health Organization classifies Aflatoxin B1 as a Group 1 carcinogen and this is a reason we test.
The result
Aflatoxin B1, B2, G1, G2, and Ochratoxin A all came back Not Detected — below the lab's own detection threshold of 0.001 µg/g. That is the best possible outcome.
Pesticide-Free Across 80+ Compounds
Our pesticide screening used two complementary analytical methods — Gas Chromatography (GC/TQ) and Liquid Chromatography (LC/TQ) — each targeting different classes of compounds. Together they cover organochlorines, organophosphates, pyrethroids, fungicides, and more.
Every single analyte returned Not Detected. Every calculated total — DDTs, Endosulfans, Chlordanes, Pyrethrins — reads 0.000 µg/g. All passing their respective action limits with substantial margin.
"Zero pesticide residues detected across more than eighty compounds."
About the Yeast & Mold Results
This panel returned actual numeric values — 300 CFU/g mold and 5,000 CFU/g yeast, for a combined 5,300 CFU/g — which we want to address directly.
What This Means for You
When we source a coffee, we're making a promise — not just about how it tastes, but about what it contains. Third-party lab testing is how we keep that promise. The results are certified by independent scientists at an accredited facility.
The Arabica Yellow Catuaí from Fazenda Santana is grown at altitude in Serra Negra, São Paulo. The farm's post-harvest practices are part of why this coffee performs so well in testing. Good farming and clean results aren't a coincidence.
We'll continue publishing certificates of analysis for every lot we bring in. Because transparency isn't a marketing strategy. It's just the right thing to do.
