who tests our tea?
an independent, accredited food safety laboratory in europe. every new batch is tested.
what do you test for?
pesticides and heavy metals: lead, cadmium and mercury, and arsenic for ube. for hojicha and mulberry we also test microbiology, such as salmonella and listeria.
what does < mean?
the value is below the lowest amount the lab can reliably measure. in other words: too low to measure.
what does ± mean?
the measurement uncertainty of the lab, with 95% confidence. every measurement has a small margin; the lab states it openly.
how often is this page updated?
with every new batch. the results here always belong to the batches we currently sell.
