The Reason Hojicha Aromas Differ: It's Not the Tea Leaves, It's the Water

Have you ever noticed that when you drink hojicha,

you think, "It's the same tea leaves, but it doesn't have the same aroma as the store-bought kind"?

You bought high-grade hojicha.

You're using tea leaves imported from Japan.

You're brewing it correctly.

Yet, something about the taste is different.

The reason that is often overlooked is "water."

In fact, the aroma and sweetness of hojicha can vary greatly not only with the tea leaves but also with the water.

What is Hojicha?

Hojicha is a type of Japanese tea made by roasting tea leaves, such as sencha or bancha, at a high temperature.

It is characterized by its fragrant, roasted aroma, low bitterness and astringency, and is enjoyed by people of all ages.

It is also popular as a tea that can be easily drunk at night due to its relatively low caffeine content.

The Appeal of Hojicha is its "Aroma"

While matcha and sencha are teas enjoyed for their umami and sweetness, hojicha is a tea enjoyed for its aroma.

The roasted aroma produces:

  • A nutty fragrance

  • An aroma like freshly baked grains

  • A gentle, sweet fragrance

are its characteristics.

That's why the perception of its aroma can change depending on the water.

Approximately 99% of Tea is Water

It may be surprising, but most of tea is water.

No matter how high-quality the tea leaves, the taste and aroma will change if the water changes.

This applies to:

  • Matcha

  • Sencha

  • Gyokuro

  • Hojicha

all types of tea.


Japanese Tea Developed in a Soft Water Culture

Japan is a country with unusually soft water globally.

Soft water is water with low mineral content, such as calcium and magnesium.

Japanese tea has developed over a long history in this soft water environment.

Therefore, soft water is said to bring out the original aroma and sweetness of tea.

The fragrant aroma that is the charm of hojicha is very delicate.

When using soft water,

  • The aroma tends to emerge easily.

  • Sweetness is easily perceived.

  • The aftertaste is clean.

  • It becomes easier to drink.

Some people feel these effects.

Because it's a tea drunk daily, you might easily notice the difference.
