番茶

Bancha is a grade of Japanese green tea made from the same plant as sencha but harvested later in the growing season, in summer or autumn. The name is written 番茶 in Japanese. The character 茶 means tea. The first character, 番, is more complex: in this context it means ordinary, common, or coarse, though the same character in other compounds means number, turn, or foreign. The compound 番茶 translates roughly as common tea or everyday tea.

The distinction between bancha and finer teas became institutionalized in Japan during the Edo period (1603–1868), when the tea trade was well organized and grades were commercially significant. First-flush leaves harvested in spring, used for gyokuro and high-grade sencha, commanded premium prices. Later harvests produced larger, tougher leaves with more tannins and less sweetness. These became bancha: cheaper to buy, coarser in texture, and lower in social standing. Yet they were drunk by more people, more often, than any of the premium grades.

The lower caffeine content of bancha is partly a function of the later harvest. Young spring leaves are metabolically active and accumulate more caffeine. Older leaves harvested in summer or autumn have lower concentrations. This made bancha the tea most commonly served in Japanese homes throughout the day, to children, elders, and guests alike, without concern about disrupting sleep. In traditional Japanese medical thought, it was also considered easier on the stomach than sencha.

Bancha is the base for hojicha, produced by roasting it over charcoal, and for some versions of genmaicha, where it is blended with roasted brown rice. It holds a structural role in the Japanese tea system that its modest reputation does not fully reflect. Western markets encountered it later than sencha or gyokuro, partly because its plainness was hard to market as premium, but it is now available in specialty stores as a deliberate choice for daily drinking.
