Lethea

Functional Darjeeling tea for the rhythm of the day.
Case study

Darjeeling tea, rebuilt as a daily ritual: one for the morning, one for the night.

RoleResearch, naming, wordmark, illustration, packaging system, campaign, retail & testing
ContextMA Graphic Branding & Identity, UAL London College of Communication, 2026
01Challenge

Darjeeling’s origin is legally protected, but the people who pick it are invisible at the shelf, and wellness brands sell vague functional promises.

02Insight

People already use tea to switch on and switch off. The ritual exists; it just needs a system.

03Idea

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.

04Outcome

Naming, custom wordmark, picker illustration, stamp system, gummies, cold brew, 20 ml sachets, capsules, cartons, campaign and retail. A/B tested with real participants.

The story

Some things should be passed down. Others shouldn’t.

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.

Capsules & concentrate

The ritual, in a single drop.

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.

Stamp system

Every pack traces its estate.

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

Sachets

One sachet. One ritual.

Flavours

Mandarin by day. Plum by night.

First Flush for the morning ritual, Second Flush for the evening.

Rush hour,
rhythm within.

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