What you need to know before talking about matcha-iri genmaicha caffeine

Before we get started on matcha genmaicha caffeine, we need to talk about a few things. Let’s briefly discuss what this tea is, how it’s made and what it tastes like.

What is matcha iri genmaicha

Matcha iri genmaicha like the Matcha Genmaicha Shizuoka is essentially made by combining genmaicha with matcha powder. As you may know, genmaicha is already a combination of green tea leaves and toasted rice. This means that matcha iri genmaicha is actually made from 3 distinct ingredients. 

While the tea leaves and the toasted rice brew inside the teapot, the matcha powder is released directly into the water.

This makes the color of the infusion a bright shade of green, and it also has certain advantages when it comes to the flavor and health benefits of the tea. It also of course affects the matcha genmaicha caffeine.

What does matcha iri genmaicha taste like?

If you’ve ever had matcha-iri you’ll know that the flavor is far more intense than a typical genmaicha tea.

This is because when you drink it, you are consuming actual powdered tea leaves in addition to the brewed tea. Of course this in addition to a higher matcha-iri genmaicha caffeine content, you also get more flavor as well.

This can definitely be a good thing as the complaint a lot of people have about certain genmaicha is that it tastes mostly like rice, without as much of this classic Japanese green tea flavor. This is fixed with the addition of the matcha powder, which more than compensates for the flavor.


Why the matcha iri genmaicha caffeine is so much higher

How matcha is produced

To produce matcha tea, a farmer first has to cut the tea leaves off from sunlight for 3 weeks. This puts the plant under a lot of stress, and causes it to produce more caffeine, as well as more of this sweet and savory theanine.

Step 1 - Harvesting the matcha

Next, the farmer selects the top 3 sprouts of the tea plant. These are selected because they are the smoothest in flavor, but they also happen to be the highest in caffeine.

Step 2 - Removal of the stems

Next, the farmer will actually remove the stems from the leaves, which raises the caffeine even further because there is less caffeine in the stems.

Step 3 - Grinding the powder

Finally, the tea is ground into a fine powder in a large stone mill and mixed directly into water. This means you get all the caffeine at once rather than releasing it slowly over the course of a few infusions.

So next time you wonder why the matcha genmaicha caffeine content is so high, you’ll understand it all comes down to how the matcha powder is produced.
