Sobacha
Roasted buckwheat groats, infused as a nutty golden drink in Japan, Korea and China. Buckwheat is not a grass and not related to wheat — it is a knotweed relative, and the seed is a fruit.

Character
Nutty and gently sweet, lighter than barley and with a distinctly buckwheat character. The groats are sometimes eaten after brewing.
Notes: roasted nut, buckwheat, toast
History
Buckwheat was domesticated in south-west China and carried across East Asia and into eastern Europe. Its use as a roasted infusion is strongest where it is also a noodle grain, which is a fair indication that the drink began as a use for broken or surplus groats.
How it is drunk
Served in soba restaurants in Japan, often alongside the noodles made from the same plant. Korean memil-cha is a household drink, and Chinese tartary buckwheat tea is a distinct and more bitter variety.
Production
Hulled groats are roasted until golden brown. Tartary buckwheat is a different species with a more bitter, more strongly flavoured seed, and is sold separately where the distinction is understood.
Preparation
Roasted grain infusion
Boiling and decoction
1–3 g/100 ml · 98–100 °C · 10 min
What gets confused
Common and tartary buckwheat are both sold as buckwheat tea and taste noticeably different. Tartary is more bitter and more strongly coloured.

Comparisons
- Tartary buckwheat vs common buckwheat — Two buckwheat species sold as one drink. The Chinese highland species is genuinely bitter — its name says so — and the Japanese one is sweet and round, and buying either expecting the other is a surprise.
- Job’s tears vs buckwheat tea — Two roasted seed drinks with a nutty body, both far heavier than a leaf infusion, and neither is a cereal in the grass-family sense that the names imply.
- Buckwheat tea vs roasted rice — Two roasted seeds that Japanese drinking handles very differently: one is served as a drink in its own right and the other exists almost entirely as a blending component.
Evidence for this page
The botanical name, family and distribution above are checked against an external authority. Fagopyrum esculentum Moench — GRIN-Global Taxonomy record— retrieved and read, not countersigned by a named human. That source covers naming and distribution only. Everything else on this page — history, culture, production, flavour, preparation and buying advice — is TeaHQ’s own synthesis with no external source behind it.
Brewing parameters here are typical practice for the category rather than measurements of this plant, and each set says so.
This page makes no safety claim. It describes what Sobacha is, where it comes from and how it is prepared — not what it does to a person. The absence of a safety note here is not a statement that the plant is safe. How TeaHQ handles this.
