Transparency: how our matcha is tested

Yes. The tea plant takes up aluminium from the acidic soils it grows in, and all tea leaves contain some. With matcha you drink the whole leaf. In Europe there is no maximum level for aluminium in food. Like all matcha, ours contains aluminium. Its lab report gives the level, and we send it to you on request.

It depends on the harvest and the amount you use. The lab report gives the level in milligrams per kilo. A cup is made with 1 g of matcha, so divide the value by 1,000. A latte is made with 2 g, so divide it by 500. We send you our lab report on request, within 24 hours.

The laboratory does not allow its reports to be reproduced, even in part, without its written consent. So we prefer to send the lab report in full, exactly as it was issued, to anyone who asks: private customers, professionals and journalists. Just fill in the form on this page.

Like any plant grown in open ground, matcha can contain traces of lead, cadmium, arsenic or mercury from the soil. The laboratory measured these four metals in our matcha, as well as copper, and found mercury and copper compliant. The values are in the lab report, sent on request.

Organic farming bans synthetic pesticides, but it cannot guarantee there are none at all: a neighbouring field or the soil can bring some in. That is why our matcha is tested. In our matcha, the laboratory's multi-residue screening found none of the pesticides on its list, and glyphosate was not quantified.

Not in this lab report, which covers metals, pesticides and hydrocarbons. Our matcha comes from Kagoshima, in the south of the island of Kyushu, more than 1,000 km from Fukushima. If radioactivity matters to you, write to our team and we will tell you exactly which documents we have.

Look on the pouch for the EU organic logo and the control body code printed next to it (ours: FR-BIO-01). Also ask for the seller's certificate, issued in the seller's name. Ours is issued in our company's name, and we send it to you on request.

Our certificate is issued in the name of our company, SKEYL, under Regulation (EU) 2018/848. It covers placing the matcha on the market and storing it, and it is valid until 31 March 2028. We send it to you on request.

Not necessarily. Heavy metals and aluminium come mainly from the soil, whether the crop is organic or not. Organic rules cover pesticides and fertilisers. That is why the organic certificate and the lab report are two different proofs. You can see both: we send them on request.

With every new harvest. The matcha is tested before it goes on sale, and this page is updated the same day.

Because the certificate that makes us accountable to you is ours, issued in our company's name. Our matcha is grown in Kagoshima, Japan, and every operator in the organic chain holds its own certification. We answer for what we sell, to every customer.

A lab test only looks for what it is asked to look for. Ours does not cover nickel, perchlorate and chlorate, pyrrolizidine alkaloids, microbiology, radioactivity or caffeine (caffeine is given in the technical data sheet). If any of these matters to you, write to our team and we will tell you which documents we have.
