Lab reports

You drink matcha every day. You have a right to know what’s in it.

That’s why we have every batch tested at ALS Laboratories, an ISO/IEC 17025 accredited laboratory with sites in the Czech Republic and the United Kingdom. For pesticides, heavy metals and microbiological contamination. You can view the reports here as PDFs. No request needed. No contact form.

What we test for

Pesticides

A GC-MS/MS pesticide screening, from herbicides to insecticides. All 240 reported values were below the reporting limit, mostly 0.01 mg/kg. The lab did not report 26 further substances because the measurement did not pass its quality control. They are listed at the end of the report. The lab rates the result as compliant with EU maximum residue levels.

Heavy metals

Lead, cadmium, chromium. Often discussed in relation to tea from Asia. The current batch measured 0.121 mg/kg lead (12 times below the EU limit), 0.040 mg/kg cadmium (5 times below the EU limit) and 0.10 mg/kg chromium.

Microbiology

Indicators of clean processing and storage. Salmonella not detected, total viable count below 10 CFU/g.

Why we make this public

We publish our lab reports here so you can read the results directly.

We believe you should know what you’re drinking, without having to ask.
