Kukicha, Japanese green tea low in theine: origin, properties, benefits, recipe

Have you heard of kukicha tea? This variety of Japanese green tea is made from the leaves of Camellia sinensis, which, according to legend, have been on the plant for at least three years. However, this doesn’t exactly work like that today.

Now, what makes kukicha different from other types of Japanese tea? To begin with, the raw material used to prepare it. Instead of selecting new shoots or small leaves, kukicha is made by separating those stems and petioles that are discarded when preparing bancha, another famous Japanese tea. In this way, this infusion has a higher concentration of tannins, being stronger than its “cousins”: bancha or sencha.

How kukicha tea is made

Kukicha is native to Japan, one of the world’s largest producers of green tea despite having very little land to cultivate. In fact, for this reason, the Japanese have become wonderful users of the raw material. That is to say that absolutely nothing is wasted (neither leaves, nor petioles, nor stems) from the tea plants.

Thus, after the flowering of the plant, its leaves are harvested for the preparation of sencha and the lower quality leaves are separated to make bancha. In the following selection process, the branches and petioles are separated but not thrown away, but reserved to make kukicha.

After mechanical separation, the branches and petioles are cut and a short-term, controlled oxidation process begins. Then, in Japanese fashion, they are steamed on bamboo trays to stop oxidation. After this process, they can be subjected to roasting or directly to air drying, and then rolled up and take on the appearance of traditional tea.

A tea with hardly any theine

A striking curiosity about kukicha is its minimal theine content: between 0.5 and 1% caffeine per cup. 

This is because this variety is prepared mainly with petioles and stems and a smaller number of leaves, which is where the highest concentration of caffeine in the plant occurs. So now you know: kukicha is a good option to drink at night, during pregnancy or lactation. And even to offer to children!

In addition, it is worth noting that its calcium content is not negligible at all. In fact, some publications indicate that a cup of kukicha would contain more calcium than a glass of milk. However, we have not found compelling scientific studies that corroborate these data.

The taste of authentic kukicha

By mainly using branches and petioles, whose exposure to the sun has been greater, the amount of tannins in this infusion is higher than that of other varieties. 

Kukicha tea has an astringent taste, with a noticeable hint of straw if it has been roasted or grassy if it has been directly dried without roasting. Its color in the cup is yellow-green and its aroma is fresh and subtle.

Health properties

Being a slightly oxidized tea, it has the same benefits as green tea. That is to say that, for example, it is rich in antioxidants. Let us remember that these substances fight against free radicals, protecting our body from different chronic diseases such as Alzheimer’s, cardiovascular problems and even cancer. 

Likewise, its antioxidant properties would prevent premature aging.

On the other hand, it is considered to have a great alkalizing power, helping to neutralize acidity and favoring good digestion. For this reason, its intake is usually recommended after heavy meals.

Kukicha tea is also rich in minerals and vitamins. Its long permanence in the plant has given it the opportunity to store a good dose of nutritional components recommended for humans.

Like green tea, kukicha has a diuretic effect that recommends its inclusion in diets to lose weight as well as in the usual menu of those with fluid retention and hypertension.

How to prepare a cup of kukicha

Whether you want to prepare roasted or unroasted Kukicha, the procedure is the same. We recommend you let yourself be advised by your trusted herbalist to acquire the variety that best suits your tastes.

Now, to prepare the infusion, you must heat the water to 80 °. It is very important that you respect the temperature since green teas are very delicate and, when faced with boiling water or at a high temperature, they can become bitter (remember that in a previous article we told you how to prevent green tea from becoming bitter). Once you have the water at the right temperature, infuse the kukicha for two minutes.

Let yourself be surprised by the subtle and different flavor of kukicha. You will see how this Japanese tea does not leave you indifferent both for its flavor and for its nutritional contribution and health benefits.

Origin of Kukicha tea

A long time ago there was not enough Sencha and Matcha so their prices were very high.

Like everything related to teas, there is great confusion and legends but, in this case, all sources indicate that it is a tea of ​​Japanese origin that comes from the production of the famous matcha tea.

The hard parts of the tea crop that could not be ground in the stone mill to make matcha were called “oremono”, and people used it to make their tea.

This was later called “shiraore”, because the stems and twigs are generally a much lighter color, close to white, than the leaves. Later it was called “kukicha”.

So we can consider that the origin of kukicha tea comes as a by-product of the manufacture of matcha tea.

However, everything evolves and today, “Kukicha tea” is considered in the West as one of the most appreciated and valued drinks, thanks to the macrobiotic diet, which considers this green tea as one of the healthiest drinks.

To make Kukicha tea, the tea leaves are collected and steamed exactly like Bancha, Sencha or Gyokuro tea.

There is confusion in considering that Kukicha and Bancha teas are the same type of tea, but it is not true because although they both come from the same plant and the same production process, Kukicha is the part that has the highest proportion of petioles than leaves and having fewer leaves has less protein content since it is in them where it accumulates. It also has a higher tannin content because it has more wood than Bancha.

Te Kukicha is also made from the production of Sencha.

When it comes from the production of Gyokuro it is called karigane or shiraore.

That is, the tea leaves are collected, they go through a mechanical selection process where the stems and twigs are separated from the leaves.

The pruned branches and stems of the tea plant are steamed and then dried.

In order to obtain the perfect drying, they are subsequently stored in bags for 3 years to achieve their aging (hence the name of three-year-old tea).

Throughout the curing or aging process, the twigs and stems are cut and classified according to their quality.

This is how the unique and indescribable flavor of “Kukicha Green Tea” is achieved: “A light flavor, with notes of walnuts and slightly creamy”.

“A light flavor, with notes of walnuts and slightly creamy”

 Although you can’t smell or taste it yet, can you imagine its aroma and taste?

 As much as you imagine it, when you try this Tea, it will exceed your expectations.

 There is also a variety of roasted kukicha or hoji-kukicha, very popular in macrobiotic circles and known simply as kukicha. But it is a roasted tea and not the most accurate way to refer to it.
