GABA content

The tea farmer ensures that a high GABA content is achieved through careful selection of the best leaves and his unique processing method.

GABA Amino Acid

GABA (γ-aminobutyric acid), is a natural amino acid and an important non-proteinogenic, endogenous amino acid.

GABA is found in various amounts in certain foods and is also formed in the brain from glutamine. It is found in particularly high amounts in special green tea GABA tea (up to 400mg/100g), tomatoes (up to about 60mg), sprouted rice, certain fermented foods, potatoes (16-60mg), citrus fruits (10-23mg).

Location, Cultivation, Processing

The tea farm is located in a valley by the Ashitaka Mountain, to the southwest of the famous Mt. Fuji. This protected area provides the perfect climate for the tea to grow, with plenty of fog and an optimal provision of water to the soil from the Sudo river, which passes through the valley. This environment, combined with innovative cultivation practices, has allowed the farm to avoid the use of chemical fertilisers and pesticides since 2003. Instead, the farm utilises high-grade organic fertilisers such as kelp and buckwheat husks to optimise the quality of the soil and encourage the growth of healthy, nutrient-rich plants.

Single Origin

This tea is exclusively sourced from the above mentioned tea farm in the Sudo River Valley. Sourced directly from the tea farmer.

Packaging

Packaged for us by the farmer in high quality, airtight, resealable standing zipper pouches.

Recommended Teapot

To serve, a Banko kyusu made from 100% violet original Banko clay is ideal. When fired, this famous clay brings out the gyokuro's flavour, amino acids, chlorophyll and other special ingredients, in the very best way. Vintage kyusus from before 1990 could still be made from 100% original clay from the Banko region. Otherwise, a high-quality shiboridashi, a handleless teapot popular among gyokuro lovers, is suitable for intensive umami infusions.

Recommended Storage

For keeping this tea fresh, a tea caddy made from cherry tree bark (solid wood, kabazaiku chazutsu), an airtight, laquered tea caddy or an elegant, handcrafted metal Kaikado tea caddy are ideal storage solutions.

The purity of our formulas is important to us.
