Genmaicha: Japanese tea with toasted rice

The teapot in our family kitchen in Kyoto is a small earthenware kyusu, brown with a darker glaze on the rim. My grandfather used it every afternoon for genmaicha, the tea with toasted rice. He would tip in two heaped scoops, pour in water that had cooled a moment, and wait, looking out at the small persimmon tree in the garden. The smell that came up was something like popcorn and grass, warm and a little sweet.

Genmaicha is one of the more humble Japanese teas. It does not have the high status of gyokuro or the formal ceremony of matcha. It belongs to the everyday kitchen, to lunchboxes packed for school, to the small thermos a farmer takes out into the fields.

The origins of the toasted rice

The standard story is that genmaicha was first made by households mixing leftover toasted brown rice with their green tea to make a small supply last longer. Whether this is fully accurate or partly folklore, the practice was clearly common in Japanese homes by the late Meiji and early Showa periods, when ordinary tea could be expensive and rice was a kitchen staple.

What began as a way to stretch the tin became a recognizable category. By the mid-twentieth century, blenders were preparing it deliberately, with carefully roasted rice and chosen leaves, and selling it in shops as its own product. The accidental blend had become an intentional one.

What goes into the cup

Two ingredients carry it. The first is a green tea base, usually bancha (the more workaday late-harvest leaves) or sometimes sencha (the more refined daily green). The second is roasted brown rice, sometimes with a small number of grains that have popped open like miniature popcorn during the toasting process.

Some versions, called matcha-iri genmaicha, also have a small amount of powdered matcha mixed in, which gives the brew a brighter green colour and a slightly fuller mouthfeel. Whether one prefers it depends on the household. My grandfather considered the matcha version a little showy. My aunt insisted on it.

“The rice quiets the tea. The tea quickens the rice. Neither asks the other to leave.” (loose translation of a phrase from a small Kyoto tea shop, 2017)

Brewing without burning

Japanese green tea is sensitive to water temperature. Boiling water makes it bitter. For genmaicha, the standard is water that has come to a boil and then been allowed to cool for one or two minutes, so it lands somewhere around eighty to ninety degrees Celsius. The leaves and rice are placed in the kyusu, water is added, and the pot is left for thirty to sixty seconds.

It is a fast brew. Over-steeping does not benefit it. The first pour goes into small cups, and the leaves are kept for a second and sometimes a third infusion. Each one is slightly different. The first is greener, the second rounder, the third quietest, with the rice character settling forward.

The kyusu, briefly

The traditional pot is small, fitted with a built-in side handle that keeps the hand at a comfortable angle. The strainer is built into the spout. There is no separate infuser to lift out. The shape is designed to pour cleanly into small cups, and to be rinsed quickly when the round is done.

The smell, and what it does to a room

The strongest character of genmaicha is its aroma. Pour hot water onto the leaves and the kitchen takes on a smell of warm toasted rice, something between popcorn and freshly cooked grain. It is a soft, low-pitched scent. Unlike the bright, almost grassy smell of pure sencha, genmaicha smells like a kitchen rather than a garden.

This is part of why it suits ordinary meals. It does not insist on attention. It pairs with rice and pickles, with grilled fish, with a small piece of fruit. Readers interested in daily wellness routines may find that this is one of the easier teas to make a calm habit of, because nothing about it asks for special equipment or special ceremony.

When to drink it

Genmaicha has caffeine, though less than sencha because the rice dilutes the proportion of leaf in the cup. Many Japanese drink it in the afternoon, with lunch or after, when a brighter green tea would feel too sharp. It is also one of the teas more often given to elderly relatives and to children, exactly because it is softer than a strong sencha.

In our family it accompanies the second half of the day. The morning is for sencha if there is energy, or hojicha if not. The afternoon, when the light slants and the work softens, is for genmaicha. The pot is small. The cups are smaller. A round takes perhaps twenty minutes.

Seasonal notes

The tea suits autumn and early winter especially well. The roasted rice character feels right with the first cool air, the change in the persimmon leaves, the lighting of small heaters under the table. Readers who follow our notes on seasonal living often write about adopting genmaicha around October, when nothing about a cup of cold water feels quite right anymore.

This is not the same as saying it is a winter-only tea. In summer it can be brewed cold, the leaves and rice left overnight in a jug of cool water in the refrigerator. The result is lighter, the rice character coming forward over the green, quietly refreshing.

A small word of care

As with any green tea, the caffeine is real, modest but present. People sensitive to caffeine, or pregnant, or on medication, will sensibly check with someone qualified before making it a long daily habit. The Japanese kitchen takes these things calmly, but it does not pretend they are nothing.

The pot, when the round is done, is emptied of leaves and rice into a small bin. It is rinsed with hot water and set upside down on a clean cloth. The persimmon tree, outside, continues to do whatever it is doing.

The afternoon shortens. The kettle has cooled. The pot waits, used and patient, for tomorrow.
