There’s no official grade called ceremonial, in Japan or anywhere else. We use it for matcha that’s shaded for three weeks or more, stone-milled, and good enough to drink with nothing but water. Ours is first-harvest leaf from Kagoshima, picked in May 2026.

Each 30 g pouch is sealed in Japan and we never open it. Sealed and kept cool, matcha holds up for about a year. Once you open it, it starts to fade, so finish it within about 30 days. That’s why the pouches are 30 g.

No. It’s heat-sealed in Japan and goes into the tin still sealed. The strip across the lid is there so you can check.

About 32 mg per gram, so roughly 64 mg in a 2 g cup. For comparison, Health Canada puts a cup of brewed coffee at about 135 mg.

About 15 cups at 2 g, or 10 lattes at 3 g. One a day means two pouches every four weeks.

Choose 1, 2 or 3 pouches per delivery and how often. Your first box brings one tin to keep (the first pouch is inside it) and any other pouches sealed. After that, refill pouches only. Skip or cancel anytime.

Subscriptions are billed on the day each box ships. You’ll get an email three days before, so you can skip or change it.

If your first order isn’t for you, tell us within 30 days of delivery and we’ll refund it in full. It doesn’t matter if you’ve opened it, and you don’t need to send it back. After your first order, unopened tins can be returned within 30 days.

Plain matcha counts as a basic grocery in Canada, so it carries no GST or HST.
