Darjeeling’s origin is legally protected, but the people who pick it are invisible at the shelf, and wellness brands sell vague functional promises.
People already use tea to switch on and switch off. The ritual exists; it just needs a system.
START (First Flush + Mandarin, 90 mg caffeine) for after waking; RELEASE (Second Flush + Plum, decaf, 54 mg L-theanine) for before sleep. Every pack traces its estate through topographic stamps.
Naming, custom wordmark, picker illustration, stamp system, gummies, cold brew, 20 ml sachets, capsules, cartons, campaign and retail. A/B tested with real participants.







Darjeeling’s name is protected by law. The people who pick it are not. Tea knowledge moves through generations, and so do the labour structures that keep value away from them.
Lethea turns that tension into a daily ritual: START for the morning, RELEASE for the night. Every pack traces its estate, its elevation and its flush, so the origin you taste is the origin you can see.








Darjeeling tea concentrate sealed in soft capsules: amber START for the morning, violet RELEASE for the night. Same estate stamps, same doses, no brewing needed.






87 garden stamps drawn from real elevation data, plus dose, flush and compound stamps that sit on every pack.






Tear, pour, dilute — a 20 ml dose for each end of the day.
First Flush for the morning ritual, Second Flush for the evening.







The city speeds up. You don’t have to. Darjeeling, two hours after waking.
