Vietnamese Matcha: How Japanese Tea Tradition Took Root in the Mountains of Son La

Vietnamese Matcha: How Japanese Tea Tradition Took Root in the Mountains of Son La

More than twenty years ago, Japanese tea specialists came to Vietnam looking for something very specific.

Not a factory. Not a cheaper place to produce tea.

They were looking for a landscape.

Somewhere cool enough, high enough and misty enough for Japanese tea varieties to grow well. Their search eventually led them into the mountains of northern Vietnam, more than 1,000 metres above sea level.

There, in Van Ho, Son La, they found what they had been looking for.

Today, long green rows of tea stretch across these highlands. For most of the year, they look much like other tea fields.

Then, shortly before the spring harvest, something unusual happens.

The fields begin to disappear.

When the Tea Fields Go Dark

About 15 to 20 days before harvest, workers cover the tea plants with black shading nets, shielding the young leaves from direct sunlight.

From a distance, entire sections of brilliant green plantation suddenly turn black.

It might look strange, but this period in darkness is deliberate — and it is one of the most important steps in producing matcha.

Instead of simply allowing the tea to grow beneath full sunlight until the day it is picked, the conditions surrounding the plant are changed during its final weeks in the field.

Under the nets, the leaves continue to develop in reduced light.

For Satoen's Premium Matcha, those leaves are harvested in spring, around March and April.

Once they are picked, another race begins.

From the Mountains to the Factory

Freshly harvested tea does not wait.

Natural oxidation begins after the leaves are picked, so they are moved quickly from the fields for processing.

At Van Ho, the journey is unusually short. Satoen's processing facility is located at the tea-growing area itself.

The leaves that were growing on the mountainside only a short time earlier now enter a completely different world of stainless steel, heat and machinery.

One of their first stops lasts only seconds.

Steam.

The fresh leaves are exposed to hot steam for approximately 15 to 20 seconds, halting oxidation and helping preserve the character of the green leaf.

It is remarkably brief considering how important the moment is.

Then the process continues.

The leaves are cooled.

Cut.

Dried.

Separated from stems and other unwanted material.

And somewhere during this transformation, the familiar appearance of a fresh tea leaf disappears.

What remains has another name.

Tencha.

The Tea Almost Nobody Sees

Most people who drink matcha will never see tencha.

It is the quiet middle chapter of the story — after the field, but before the brilliant green powder.

Tencha is the raw material from which matcha is made.

At this point there is still no bowl, no bamboo whisk and no layer of green foam. The processed tea still looks much closer to dried leaves than to the matcha most of us recognise.

Only after further preparation does the final transformation begin.

The tencha enters specialised grinding equipment.

Slowly, the leaf becomes powder.

Finer.

And finer still.

According to Satoen, its matcha is ultimately ground to particles measuring approximately 10 to 15 microns.

To the eye, the structure of the original leaf has vanished completely.

What comes out is an intensely green, exceptionally fine powder.

Matcha.

But the tea itself was grown and transformed into matcha here, in Vietnam.

So How Did Matcha End Up in Vietnam?

That question is what makes Van Ho particularly interesting.

Matcha is deeply connected to Japanese tea culture. The techniques behind its cultivation and production were developed and refined in Japan, and Japan remains its cultural home.

But the tea growing in these fields has another geography.

Satoen Japan began exploring Vietnam more than two decades ago, searching for conditions suitable for cultivating Japanese tea varieties.

Van Ho offered a combination they were looking for: elevations above 1,000 metres, a cooler highland climate, frequent mist and suitable soil.

Japanese tea plants were established here, while cultivation and processing developed with Japanese technical knowledge and the involvement of experienced tea specialists from Satoen Japan.

Yet nothing can transplant the landscape itself.

The rain falling on these fields is Vietnamese.

The mist settling over the mountains belongs to Son La.

The soil beneath the plants is the soil of Van Ho.

And every leaf used to make this matcha begins its life here.

That makes the distinction important.

This isn't matcha trying to disguise where it comes from.

It is Vietnamese matcha shaped by Japanese tea expertise.

From a Leaf to Something You Drink Whole

There is another reason all this processing matters.

Prepare an ordinary loose-leaf green tea and, once the infusion is finished, the leaves remain behind.

Matcha is different.

The leaf itself has been transformed into powder.

Sift a small amount into a bowl, add hot water and whisk it with a bamboo chasen, and the powder disperses through the water until the two become almost impossible to distinguish.

Nothing needs to be removed.

The leaf that once grew beneath black nets on a mountainside in northern Vietnam is now in the bowl.

For Satoen's spring-harvest Premium Matcha, the finished tea has a naturally smooth, gently sweet character and a vivid green appearance.

It can be prepared simply with water, poured over ice or combined with milk for a matcha latte.

But by the time it reaches the cup, almost every trace of the journey that created it has disappeared.

Unless you know where to look.

A Bowl of Matcha, a Vietnamese Mountain

Look at the finished bowl and there is no obvious sign of Van Ho.

You cannot see the mountains.

You cannot see the workers stretching black nets across rows of tea.

You cannot see the harvesting machines moving through the spring fields.

You cannot see the few seconds of steam, the drying leaves or the tencha disappearing into the grinders.

There is only green powder, water and foam.

And perhaps that is what makes its story so unexpected.

Tea has crossed borders for centuries. Plants travel. Techniques travel. Knowledge moves from one culture to another.

Here, Japanese tea knowledge travelled to the mountains of Vietnam.

But what grew from it belongs to the place where it was planted.

Vietnamese matcha does not need to pretend to come from Japan to be interesting.

Its story is interesting precisely because it doesn't.

It already has a place, a landscape and a story of its own.
