A cold-extraction process 30× longer than standard production — unlocking the aroma sleeping within every leaf.
Conventional bottled tea is brewed fast and hot — optimized for yield, not flavor. ARTERRA's cold-extraction method takes approximately 30× longer than standard PET production, drawing each drop at low temperature to unlock the refined, elegant aroma that high heat destroys before it ever reaches the bottle.
The result is a concentration of theanine — the umami compound responsible for the deep, lingering sweetness unique to fine Japanese tea — alongside a full spectrum of volatile aromatics preserved exactly as nature intended. No preservatives. No added flavorings. No colorants. Just tea leaves and water, given time.
Only select-grade Japanese tea leaves are used. Origin, harvest season, and processing method are verified before any production begins. The quality of the leaf determines everything.
Leaves steep at low temperature for approximately 30 times the duration of conventional brewing — releasing theanine and delicate aromatics that heat-based methods permanently destroy.
No preservatives, no added sugars, no artificial flavoring, no colorants. The extracted liquid is filtered and bottled with minimum intervention — preserving every compound the leaf contains.
Each batch is verified for theanine concentration, aroma profile, color, and microbiological integrity before release. Only product that meets the full specification ships.
