Best certified organic.
The label and the reality.

What «certified» actually means

Great Britain runs its own organic scheme since Brexit. Food can only be sold as organic if it is certified by a control body approved by Defra, and the label carries that body’s code, such as GB-ORG-05. Organic goods certified in the EU are recognised for sale in Great Britain, but the EU leaf on its own is not a British certification, and a matcha carrying only JAS, the Japanese standard, cannot be labelled organic here without going through that recognition.

Plenty of matchas on sale in Europe use the word «organic» with no verifiable certification behind it. This ranking only includes those that can produce their certification with a batch number.

The matchas whose certification we checked

Why organic certification does not guarantee sensory quality

Organic certification covers the production process, not the quality of what comes out of it. A matcha can be 100% organic and still be a second harvest with coarse milling and a flat profile. Conversely, some of the best artisan matchas from Uji are not certified, because certifying costs money that many small farms do not spend. Treat certification as one more criterion, never as the only one.
