In the mountains of northern Vietnam, where the air is cool and clean and the mists curl gently through the trees, something special is growing

Our GABA tea begins here—on small tea farms nestled among the hills, where every leaf is harvested by hand with care and reverence. But what makes GABA tea so unique isn’t just where it comes from. It’s how it’s made

What makes GABA tea different?

Most teas are oxidized as part of their processing. The leaves are exposed to oxygen, which alters their chemical composition and flavor. GABA tea takes a different path. After harvest, the leaves are placed in an anaerobic chamber—a sealed environment where the oxygen is replaced with pure nitrogen

This oxygen-free process does something fascinating: it triggers a transformation in the tea’s chemistry. Inside the leaves, an amino acid called glutamic acid is converted into GABA (gamma-aminobutyric acid)—a naturally calming neurotransmitter that our brains use to regulate stress and nervous system function

Unlike traditional fermentation—which involves microbial activity—this process is anaerobic, not microbial. No bacteria or fungi are breaking down the tea. Instead, the nitrogen-rich environment prevents oxidation and promotes this natural conversion of glutamic acid to GABA

The result? A tea that is smooth, nutty, and grounding, with functional benefits for mental clarity, relaxation, and nervous system balance

The steps of the GABA tea journey

Harvest
Young, tender leaves are picked by hand, typically from high-elevation farms in the Vietnamese mountains. These higher altitudes promote slower leaf growth and greater complexity of flavor

Withering
Leaves are gently laid out to lose some of their moisture while preserving their integrity

Anaerobic Processing
This is the heart of GABA tea. Leaves are sealed in a nitrogen-rich, oxygen-free chamber for 6 to 12 hours (sometimes longer), depending on the producer’s technique. This is not fermentation in the traditional sense—it is a carefully controlled, oxygen-free chemical transformation

Drying & Rolling
After the anaerobic stage, the leaves are carefully rolled and dried to lock in flavor and preserve the tea

Finishing Touches
Some GABA teas are lightly roasted or steamed, depending on the desired final profile—nutty, grassy, sweet, or floral

From the mountains to your cup

Our GABA tea is sourced from the lush mountains of Vietnam, where it’s crafted using this distinctive anaerobic technique. The process retains the freshness of the tea while boosting its GABA content, resulting in a tea that’s lower in caffeine than many black teas—but high in calming, cognitive benefits

Because no microbes are involved, GABA tea is not fermented in the way pu’er or dark teas are. But its transformation is just as remarkable. It’s a tea born of chemistry, care, and tradition—a quiet innovation that nourishes both mind and body

A tea with intention

What you get in your cup is more than a calming tea—it’s the result of innovation, care, and deep knowledge of plant chemistry. GABA tea is one of the few teas that has been scientifically refined to enhance wellness on a neurological level, while still delivering all the antioxidant and polyphenol benefits of a high-quality oolong or black tea

So the next time you sip, know that it’s not just a drink.
It’s a quiet revolution—in a cup
