Make Your Own Genmaicha Tea

I’m a coffee drinker that also loves tea. When I chat with other coffee drinkers they often don’t share my love for tea. One of the big reasons I believe is that often their only experience is with low grade bagged tea or that dreadful Genmaicha tea served at many sushi restaurants. In a future article, I’ll extend my hand and guide the coffee enthusiast into the world of quality loose leaf tea. For this post, I’m just going to tackle Genmaicha.

Genmaicha tea is a Japanese green tea that is blended with toasted brown rice. The history of the tea was that poor families added the rice to stretch out the tea and save money. I believe the toasted rice also serves a secondary function and that is to cover up defects in the tea itself. The most common defect being staleness.

Earlier this year, if you would have asked me what my least favorite tea was, I would have said Genmaicha. Then I challenged my assumptions. What if I made my own at home and got each step right? Would it be enjoyable?

Now I know some people who like the Genmaicha tea served at restaurants. Good for you. I think it is nasty and can be greatly improved when you make your own. I’ve discovered 4 reasons why Genmaicha tea can taste awful.

  1. Low grade or stale tea.
  2. Too much rice. Stale rice?
  3. Brewed at too high of a temperature.
  4. Steeped too long.

Source Fresh Bancha Tea

Bancha is a Japanese green tea that comes from the same tree as sencha tea. It is harvested later and has a lower market price. When I started this experiment, I first chose sencha tea. Many Genmaicha blends use sencha, but in my tests I preferred bancha. Sencha tastes wonderful by itself, whereas I felt the bancha complimented the toasted rice better.

Low grade tea is often used to make Genmaicha and some producers know that the toasted rice flavor can cover up defects or staleness, so be sure to find a fresh source of bancha tea. Many tea enthusiasts say that Japanese green tea has a maximum shelf life of just 6 months. Other teas such as oolongs and black can keep longer.

Toast Your Own Rice

Get out a skillet and place the heat on medium high. Pour out a few tablespoons of brown rice. It will get toasty brown and a few of the grains might even pop into what appears to be popcorn. Genmaicha is sometimes called popcorn tea. That “popcorn” isn’t corn, it comes from heating the brown rice. In order to prevent burning what I did was pull most of the rice once it got a toasty look to it. Then I returned some of the rice to the skillet and cooked a little longer until the grains started popping. Afterwards, I post blended the popped rice with the unpopped rice.

Once you have your own supply of toasted rice, you can add as much or as little as you like. My personal taste is to use just under 1 teaspoon for a single 14 ounce mug. I get the toasty flavor and can still appreciate the brightness of the tea. I keep my toasted rice in a sealed container. I don’t know how long it will keep fresh past roasting, so I only toast up what I’ll need for the next few weeks.

Brewing Method

Japanese green tea is the most sensitive tea to heat. You want a lower temperature. I use the range of 165-175F. The Pino Digital Kettle Pro allows you to enter the exact temperature you wish to heat your water and then shuts off when it hits that temperature.

The standard brewing ratio for tea is 3 grams of tea for every 8 ounces of water.

In addition to using a lower temperature, the steep time will be shorter. About 90 seconds is all you need. When you brew at a higher temperature or steep longer, the tea becomes more bitter. My brewing parameters can be tweaked to your liking. I have found that the lower temperature and steep time allow me to get an additional one or two steeps, whereas a longer steep or higher temperature may only yield a single good cup of tea.

A Good Genmaicha?

Two months ago I couldn’t stand Genmaicha tea. Now I am a fan. Not the swill they serve at sushi places, but the stuff I make at home. It is super easy to do. Give it a try and if you want to make it even better you can add a little powdered matcha, but that is optional.

Michael Allen Smith fell in love with coffee while attending college. Shortly after graduating college, he found himself in the Tampa Bay area far away from the good coffee he had at The Ohio State University. That is when he starting home roasting coffee. Less than a year later in April 1999, he launched the coffee website has been going strong ever since with hundreds of articles and tutorials submitted by over one hundred contributors.

In 2007, Michael moved to America's coffee capitol Seattle, Washington. He has visited close to three hundred different coffee places in Seattle, Portland,Vancouver and San Francisco and met many of the top roasters and baristas in the country. Since 2009, Michael has been the Organizer of the Coffee Club of Seattle, which is a Meetup group of over 800 coffee enthusiasts. Besides the social aspect of the group, the Coffee Club of Seattle partners with local coffee professionals for educational events such as coffee cuppings, brewing demonstrations and roasting tours.

Unrelated to coffee, Michael has a personal blog at which covers several topics including fitness, cooking and economics.
