Genmaicha Caffeine: Strong Kick or Slight Buzz?

When you think of unique teas, genmaicha might be one of the first that comes to mind. 

The first time I tried genmaicha tea was at a Japanese restaurant. The taste had the green tea flavor I knew so well, but there was a savory twist. I was surprised to find out that this tea combined both green tea leaves and roasted brown rice. 

Since then, it’s become one of the staple teas I enjoy. 

Like most teas, genmaicha does contain caffeine. And one of the questions I get often is about genmaicha caffeine level. Although it is a green tea, its caffeine level is not as high as you’d think.

You might be wondering, will genmaicha give me a strong kick-start to my day or just a gentle nudge?

Well, you’re in the right place! This blog will cover exactly how much caffeine is in genmaicha tea. And if you’re unfamiliar with this tea, this blog is for you. We’ll review its potential health benefits and how to brew this unique tea.

What is Genmaicha Tea?

Genmaicha tea is a unique Japanese tea made by mixing green tea leaves with roasted and popped brown rice. It’s also sometimes called “popcorn tea” because some rice kernels pop during the toasting process and resemble popcorn. 

If you’ve ever had genmaicha tea, you would have tasted the unique flavor and distinct aroma. The infusion of roasted brown rice and green tea leaves gives genmaicha a nutty flavor that differs from other tea varieties.

The name “Genmai” means brown rice, but there are varieties of this tea that use white rice. Of course, the taste will vary depending on the rice used.

Genmaicha isn’t just known for its taste. It also has numerous health benefits because of its antioxidant content. Since it contains green tea leaves, the antioxidants can help fight free radicals that cause damage to the body. 

Origins of Genmaicha Tea 

Genmaicha tea is a traditional Japanese tea that has been enjoyed for centuries. Its origins can be traced back to the Edo period in Japan, which lasted from 1603 to 1868. At that time, green tea was considered a luxury item and was only consumed by the wealthy.

People began mixing green tea leaves with toasted rice to make the tea more affordable. This made the tea more affordable and gave it a unique nutty flavor and aroma. The combination of green tea and toasted rice became known as Genmaicha tea.

Over time, Genmaicha tea became a beloved beverage and continues to be enjoyed today. It’s popular during the colder months, as it’s a warm and comforting drink.

What Does Genmaicha Taste Like?

Genmaicha is often described as having a delightful balance of flavors. At its heart, it’s a green tea, so you can expect those familiar grassy and slightly astringent notes. While the roasted rice imparts a distinctive nutty and toasty flavor to the brew.

When sipped, genmaicha offers a smooth, mild taste. The roasted rice also adds an almost popcorn-like undertone, and sometimes, you might even find actual popcorn grains in the mix.

Does Genmaicha Have Caffeine?

Yes, genmaicha has caffeine however it contains a significantly lower amount due to its combination of green tea and roasted brown rice.

Genmaicha, being a type of green tea, naturally contains caffeine, but typically less than other green teas. Why? Because the inclusion of roasted brown rice dilutes the proportion of tea leaves in the mix, and it’s the tea leaves that contain caffeine.

The rice is solely used to contribute to its aromatic fragrance and balance out green tea’s astringency. The source of caffeine for genmaicha comes from green tea leaves, which come from the Camellia sinensis plant.

How Much Caffeine is in Genmaicha Green Tea?

The amount of caffeine in each tea can vary widely based on factors like the type of tea, how it’s prepared, and how long it’s steeped.

On average, an 8-ounce (240-milliliter) cup of genmaicha contains about 20 milligrams of caffeine. To put that in perspective, a regular serving of green tea contains 30 to 50 milligrams while coffee contains 95 to 200 milligrams.

Other tea varieties, such as black or jasmine tea have more caffeine. Genmaicha caffeine content is much lower, which means it’s a good tea for those sensitive to the effects of caffeine.

Comparing Genmaicha Caffeine Vs. Green Tea

How does genmaicha caffeine stack up against other popular green teas?

Genmaicha tends to sit on the lower end of the caffeine scale when compared to other popular green teas. So, if you’re looking for a milder caffeine experience, genmaicha is a fantastic choice.

Here’s a comparison of the amount of caffeine in a 100g serving of different Japanese green teas.

Type of Tea	Caffeine Content (per 8 oz cup)
Genmaicha	20 mg
Gyokuro	120-140 mg
Matcha	70 mg
Sencha	25-30 mg
Hojicha	10 mg
Oolong	35-55 mg
Jasmine	15-60 mg

As you see in the chart, genmaicha has much less caffeine compared to other Japanese green teas. Gyokuro contains the most caffeine while hojicha contains the least.

Sencha is a traditional Japanese green tea known for its bright green color and refreshing taste. With 25 to 30 milligrams per 8-ounce cup, it has a higher caffeine level than genmaicha.

Matcha is arguably the most popular Japanese green tea and contains 30-70 milligrams per 8-ounce cup. It’s a powdered green tea, and because you consume the entire tea leaf when you drink it, it generally contains more caffeine than other green teas.

Gyokuro is shaded for several weeks before harvest which increases the caffeine. With 120-140 mg, it’s one of the highest in terms of caffeine among green teas.

Comparing Genmaicha Caffeine Vs. Coffee

If you’ve ever wondered how the caffeine in your genmaicha green tea stacks up against that morning cup of joe, we’re here to break it down for you in the simplest terms.

When comparing the caffeine content, genmaicha has significantly less caffeine than coffee. Genmaicha caffeine provides a gentle energy while coffee provides a stronger energy boost.

As we mentioned earlier, an average 8-ounce (240-milliliter) cup of genmaicha contains around 20-30 milligrams of caffeine. The caffeine content is a bit diluted due to the presence of the roasted rice, which contains no caffeine.

Coffee, on the other hand, is a heavyweight in the caffeine department. A standard 8-ounce (240-milliliter) cup of brewed coffee packs a more robust caffeine punch, ranging between 95-200 milligrams.

If you prefer calm alertness then genmaicha might be your cup of tea. But if you’re looking for a stronger jolt to kickstart your day, coffee’s got your back.

How To Lower The Genmaicha Caffeine Content

Even though genmaicha already has a modest caffeine content, there might be times when you’d like it even lighter. Here are some quick steps to help you reduce the caffeine in your genmaicha brew:

1. Shorter Steeping Time

The caffeine content in your cup increases the longer you let the tea leaves steep. For a milder brew, you might want to steep your genmaicha for just 30 seconds to 1 minute.

But the drawback is that a shorter steeping time will lead to a less flavorful cup.

2. Cooler Water Temperature

The water temperature can also play a role. Hotter water tends to extract caffeine more effectively. So, rather than using boiling water, aim for a slightly cooler temperature, around 175°F (80°C), when brewing your genmaicha.

Or better yet, try cold steeping genmaicha for a subtle flavor and less caffeine.

3. Use Fewer Tea Leaves

Another method is to reduce the amount of tea leaves you use. By simply using fewer tea leaves, you’ll naturally decrease the caffeine content of your brew.

For instance, if you’ve been using a full tablespoon of leaves, consider trying just a teaspoon.

4. Pre-Rinse the Leaves

You can also give your tea leaves a quick pre-rinse. This involves pouring hot water over your tea leaves, letting them sit for about 30 seconds, and then discarding that water.

After this, you can brew your tea as usual. This initial rinse can help to wash away a portion of the caffeine.

5. Opt for Low-Caffeine Brands

Lastly, while shopping for your tea, be on the lookout for brands that offer low-caffeine genmaicha. Some manufacturers produce genmaicha specifically designed to have a lower caffeine content.

Does Genmaicha Tea Have Caffeine When Prepared Cold?

Yes, genmaicha, whether hot-brewed or cold-brewed, contains caffeine. The source of the caffeine is the green tea leaves in the blend. However, cold brewing generally extracts caffeine at a slower rate than hot brewing.

There’s less caffeine when preparing genmaicha cold because caffeine dissolves faster in hot water. But given the extended steeping time of cold brewing (often many hours), the end caffeine content can be somewhat comparable to hot-brewed tea.

Health Benefits of Genmaicha

Along with being a delicious and refreshing tea, genmaicha contains numerous antioxidants that have been found to have many positive effects on overall health.

The combination provides a rich source of minerals such as phosphorus, iron, potassium, and manganese. Additionally, green tea contains polyphenol antioxidants which can help protect against the onset of some diseases, such as cancer and type 2 diabetes.

Here are several potential health benefits of drinking genmaicha tea:

Reduce Inflammation

According to research, green tea is rich in polyphenols and flavonoids like catechin and potent antioxidants that can help reduce inflammation and fight inflammation against free radicals and may even have anti-cancer properties.

Improve The Immune System

It contains lignans which have been shown to improve immune function and extra vitamins B6, niacin, and pantothenic acid – all of which contribute to a healthier body.

Regular Blood Sugar Levels

Studies show that the caffeine content of genmaicha is lower than most other teas, which helps regulate blood sugar levels and provide an energy boost without stimulating jitters or stress caused by overconsumption of caffeine.

Lower Cholesterol

Studies have also shown that green tea may lower cholesterol levels by binding bile acids stored in fat lipids. This can lower bad cholesterol (LDL) levels while increasing good cholesterol (HDL).
