Matcha: The Vivid Green Tea Shaking Up the Global Palate

From Los Angeles to London, Paris to Sydney, a vibrant green powder is becoming the signature order at trendy cafes. Matcha, the finely ground green tea steeped in Japanese tradition, has evolved into a global wellness and lifestyle phenomenon. But as its popularity soars, the centuries-old Japanese producers at its source are facing the immense challenge of meeting unprecedented international demand.

Here’s a deeper look at the world of matcha, a drink that bridges ancient ceremony and modern influencer culture.

What Exactly is Matcha?

The word “matcha” (抹茶) literally means “ground tea.” Unlike traditional green tea, where leaves are steeped and discarded, matcha involves consuming the entire leaf in a powdered form. This is whisked with hot water to create a frothy, emerald-green beverage, or blended with milk for the now-ubiquitous matcha latte.

Green tea first arrived in Japan from China in the 9th century, primarily used by Buddhist monks to aid meditation. However, matcha as we know it emerged centuries later. In the 16th century, the tea master Sen no Rikyu codified the “Way of Tea” (茶道, sadō or chadō), a spiritual and aesthetic discipline centered around the meticulous preparation and consumption of matcha. This transformed it from a simple beverage into an art form.

Today, matcha is categorized by grade:

• Ceremonial Grade: The highest quality, made from the youngest tea leaves, stone-ground to an incredibly fine powder. It’s intended to be enjoyed on its own, with a delicate, sweet, and umami-rich flavor.

• Premium Grade: High-quality matcha suitable for daily drinking, balancing flavor and cost.

• Culinary Grade: A more robust, slightly bitter matcha designed specifically for baking, cooking, and blending into lattes and smoothies, where its flavor stands up to other ingredients.

The Meticulous Art of Matcha Production

Creating authentic matcha is a labor-intensive process that can take weeks.

It begins with the cultivation of tencha leaves. Several weeks before harvest, the tea fields are shaded with black netting or traditional reed screens. This technique, known as oishita-en, forces the plants to produce more chlorophyll (giving matcha its vivid color) and boosts levels of L-Theanine, the amino acid responsible for matcha’s unique, calming energy.

“Shading the plants requires the construction of a complex structure with poles and a roof to filter the light,” explained Masahiro Okutomi, a tea producer in Sayama, northwest of Tokyo. “It’s this step that builds the foundation for matcha’s signature flavor and health profile.”

After being hand-picked, the tencha leaves are steamed to halt oxidation, then dried and aged in cold storage to deepen the flavor. Crucially, the stems and veins are meticulously removed. The remaining leaf material, known as arae-cha, is then slowly ground between two granite stone mills. This traditional method prevents the tea from overheating and losing its delicate qualities.

The output is painstakingly slow—it can take an hour to produce just 40 grams (1.4 ounces) of premium powder. This intricate process makes high-quality matcha, on average, at least twice as expensive to produce as standard green tea leaves.

A Powerhouse of Flavor and Function

Many are drawn to matcha for its complex, vegetal taste—a balance of sweet, bitter, and umami notes. But its rise is also fueled by its impressive nutritional portfolio.

Matcha is a potent source of antioxidants, particularly catechins like EGCg, which are linked to numerous health benefits. Its caffeine content provides a sustained energy boost without the jitters or crash often associated with coffee. This is due to the presence of L-Theanine, which promotes alert relaxation.

“One cup contains on average 48 milligrams of caffeine, slightly less than a drip coffee but nearly twice as much as standardly brewed green tea,” said a nutritionist. “The combination with L-Theanine creates a unique ‘calm alertness’ that is highly sought after.”

For many, the appeal is as much cultural as it is chemical. “Matcha is often seen as being good for your health,” said Shigehito Nishikida, manager of the Tokyo tea shop Jugetsudo. “But people are also attracted to the Japanese culture around tea: the ritual, the time taken, the aesthetics. In a fast-paced world, making a bowl of matcha is a moment of mindfulness.”

A Global Phenomenon, A Local Strain

The numbers tell a story of explosive growth. Japan produced 4,176 tons of matcha in 2023—a staggering 190% increase from the 1,430 tons produced in 2012. According to the agriculture ministry, more than half of this powder is now exported, with the United States, Southeast Asia, Europe, Australia, and the Middle East leading demand.

Social media has been the primary engine of this boom. Millions of videos on TikTok, Instagram, and YouTube showcase the hypnotic ritual of whisking the powder, the photogenic appeal of a bright green latte, and reviews of traditional tools like the bamboo whisk (chasen) and scoop (chashaku).

“I feel like Gen Z really drove this enthusiasm for matcha, and they heavily relied on social media to do so,” said Stevie Youssef, a 31-year-old marketing professional, at a matcha bar in Los Angeles.

The trend has also expanded beyond the teacup. Matcha is now a star ingredient in kitchens worldwide, flavoring everything from artisanal chocolates, ice cream, and cheesecakes to savory dishes like soba noodles and salad dressings.

“The clientele is incredibly diverse,” observed Nishikida of Jugetsudo. “Some customers simply enjoy drinking it, others like preparing it themselves for a moment of peace. And of course, many buy it as a gift—authentic Japanese matcha is always appreciated.”

The Challenge Ahead

This global craze, however, puts immense pressure on Japanese producers. The meticulous, time-consuming nature of traditional matcha production limits how quickly supply can scale. Climate change, an aging farmer population, and the risk of lower-quality imitations from other countries pose significant threats to the industry’s sustainability and standards.

As the world’s thirst for matcha grows, the future of this vibrant green tea hinges on balancing its newfound global popularity with the preservation of the ancient traditions that made it so special in the first place.
