Roasted soybean
Soybeans roasted until dark and nutty, brewed as a drink in Korea and ground into kinako in Japan. It is a legume rather than a grain and behaves like one — the body is heavier and the flavour rounder than any cereal drink.

Character
Nutty and full with a malty sweetness, heavier in the mouth than barley or corn tea. Kinako whisked into hot water is thicker again and closer to a drink than an infusion.
Notes: roasted nuts, cereal, malt
History
The soybean has been cultivated in northern China for over three thousand years and reached Korea and Japan early, where it underpins a large part of both cuisines. Roasting whole beans for a drink is a domestic practice rather than an industrial product, and it is far less common than the fermented and curdled uses.
How it is drunk
Brewed at home in Korea, and roasted soy flour — kinako — is dusted over Japanese mochi and warabimochi and whisked into hot drinks. It is often blended with barley or corn rather than drunk alone.
Production
Beans are roasted whole until deep brown and split, then brewed or ground. Roasting removes the raw beany note that untoasted soy carries, and under-roasted material tastes green and flat.
Preparation
Roasted grain infusion · Whisked
Herbal infusion (tisane)
2–4 g/100 ml · 95–100 °C · 6 min
Category-typical for roasted grain drinks rather than measured for this grain. Roasted material is already cooked, so the usual failure is under-dosing rather than over-steeping.
What gets confused
Kinako and brewed roasted soy are different preparations of the same roasted bean. Kinako varies in roast depth between producers more than most people notice.
Common mistakes
- Under-roasting. Raw or lightly roasted soy has a green beany note that no amount of brewing removes.

Comparisons
- Roasted soybean vs barley tea — Two deeply roasted seed drinks with a malty sweetness, both drunk at the table rather than as a speciality. The legume is heavier in the mouth than the grain by a clear margin.
- Job’s tears vs roasted soybean — Two heavy roasted-seed drinks of Korea and Japan, both thick enough to be a light meal in their powdered forms, and neither is a cereal in the way its name suggests.
Evidence for this page
The botanical name, family and distribution above are checked against an external authority. Glycine max (L.) Merr. — 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 Roasted soybean 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.
