Genmaicha: green tea with roasted rice, mild and nutty

Genmaicha is Japanese green tea mixed with roasted rice. It is one of the most drinkable teas in Japanese daily life, and the first one many people fall in love with if they find regular green tea too grassy or sharp. The aroma is warm and grainy, almost like freshly baked bread or popcorn, and in the cup, the fresh green note is met by a round, nutty sweetness from the rice.

Among the rice grains, there are often some that have cracked open during roasting and look like small popcorn. This is why the tea is sometimes called popcorn tea. The taste is softer and fuller than that of pure green tea, with hints of roasted grain, butter, and a faint sweetness reminiscent of warm porridge.

Genmaicha also has a low caffeine content, as the rice makes up a large part of the blend. This makes the tea easy to return to throughout the day and into the evening. With us, genmaicha is included in our Japanese tea tasting box along with sencha and hojicha, precisely because it is such a good introduction to Japanese tea.

What is genmaicha

The word genmai means brown, unpolished rice. Genmaicha is therefore green tea with roasted rice, and the name says exactly what it is. The rice is roasted until it turns golden brown and nutty in aroma, and then mixed with the tea leaves in roughly equal parts.

The tea has simple, humble roots. Rice was originally a way to extend the tea so that it lasted longer, but the blend turned out to be something unique. The roasted rice balances the tea's freshness and provides a taste that is easy to like from the first cup. Today, genmaicha is drunk daily in Japanese homes and is often served with meals.

Traditionally, bancha is used as the base, a tea harvested late in the season when the leaves have grown larger and milder. Finer varieties are made with sencha, which results in a lighter and slightly sweeter tea. There is also matcha-iri genmaicha, where a little matcha has been whisked into the blend. It gets a greener color, a creamier feel, and a fuller taste.

Why roasted rice gives a mild and nutty taste

The difference between genmaicha and pure green tea lies in the rice, both in taste and caffeine. Since a large part of the blend consists of rice, there are simply fewer tea leaves per cup. The caffeine in tea comes from the leaves, so a cup of genmaicha often lands around 20 to 30 milligrams, significantly lower than a cup of sencha or a cup of coffee.

When the rice is roasted, the same thing happens as when bread browns in the oven or coffee beans darken. The Maillard reaction forms new aromas that lean towards nuts, roasted grain, and popcorn. These notes form a warm layer on top of the tea's green freshness and at the same time soften the slight bitterness that green tea can otherwise have.

The result is a tea that feels balanced and relaxed. The low caffeine content means you can drink it late in the day without disturbing your sleep, which is one of the reasons it is so common with evening meals in Japan.

Bancha or sencha as base

Which tea base is used is clearly noticeable in the cup. Bancha gives a soft, round, and very easy-to-drink genmaicha with a distinct roasted character. Sencha as a base instead provides a lighter and fresher brew with more umami and slightly more caffeine, as the leaves are younger and picked earlier in the season.

Our own sencha has a background worth mentioning here. Uogashi Sencha belongs to the deep-steamed tradition from Shizuoka that became known through Uogashi Meicha, a teahouse founded in 1931 near the Tokyo fish market. Their idea is simple: good tea brews golden. High-quality deep-steamed leaves give a brew with a warm, golden tone instead of pale green, and it is the same fresh base that elevates a genmaicha made with sencha.

How to brew genmaicha without bitterness

Genmaicha is forgiving but does not like boiling water. Water that is too hot extracts too many catechins from the tea leaves, and then the taste tips over into bitterness while the rice sweetness disappears. Aim for around 80 degrees Celsius, roughly as when you let freshly boiled water cool for a short while.

Use about 2 grams of tea per 1.8 deciliters of water and let it steep for approximately one to two minutes. Taste your way, as the degree of roasting varies between different teas. The leaves and rice also hold for several infusions, so save them and pour new water for a second cup which often turns out just as good.

In the summer, genmaicha is great as cold-brewed tea. Place tea and cold water in a pot and let it stand in the fridge for a few hours, the same method we describe in the guide to mizudashi sencha. You can find brewing temperatures for all three varieties collected on our page about Japanese tea.

Genmaicha with food and in everyday life

Few teas pair as well with food as genmaicha. Its nutty, roasted tone goes well with rice, grilled dishes, fish, and everyday meals, and its mild taste cleanses the palate between bites without overpowering. In Japan, it is a natural table tea for this very reason.

It is also a grateful tea to start the day calmly with, or to brew a large pot of when several people are sharing. For those who find sencha a little too intense or matcha too much, genmaicha is a soft middle ground. It provides the Japanese green character but in a warmer, more relaxed form.

Genmaicha, sencha and hojicha

The three teas in our tasting box complement each other. Sencha is the fresh, grassy everyday tea with clear umami. Hojicha is roasted over high heat and leans towards nuts, chocolate, and wood. Genmaicha falls somewhere in between, with green tea at the base and roasted rice on top.

Tasting them side by side is the easiest way to understand what you like yourself. If you want to compare the unroasted varieties more closely, you can read our guide on sencha vs matcha.

Genmaicha is available from us in Cha Cha Cha, our Japanese tea tasting box, along with sencha and hojicha. It's an easy way to taste three Japanese teas and find your favorite.
