Holistic Roasters biodynamic coffee — independently lab-tested for purity

Third-Party Lab Results

Every harvest of our Biodynamic coffee is sent to independent, accredited laboratories before it reaches you. We publish every certificate of analysis here, unedited.

Because our coffee is Demeter-certified Biodynamic, no synthetic pesticides, herbicides, or fungicides are permitted anywhere on the farm — purity is built in at the source rather than chased after the fact. Our lab testing therefore focuses on what actually matters for a clean cup: mycotoxins (ochratoxin A and aflatoxins), heavy metals (lead, cadmium, arsenic), and microbiological contaminants.

We use two complementary third-party laboratories: Actlabs Agriculture Division performs the 16-compound mycotoxin panel by LC-MS (covering ochratoxin A, aflatoxins B1/B2/G1/G2, DON, fumonisins, T-2, HT-2, zearalenone, and more), and Eurofins Essais Alimentaires performs both the heavy metals panel by ICP-MS (lead, cadmium, mercury, arsenic) and the microbiological contaminants panel (E. coli, Salmonella, Listeria). Both laboratories are ISO 17025 accredited. Each certificate below identifies the performing laboratory.
