BLU
瑠Pure butterfly pea blue matcha — Clitoria ternatea micro-stone-ground, no green tea. Bistrica still water, sage cold infusion, single lemon-zest spritz at the rim. Caffeine 0mg. The Adriatic evening drink for the subscriber who is done with caffeine by 17:00.
BLU is the answer to a question MA7CHA's subscribers ask within the first month: 'what do I drink at 19:00 when I want the ritual but not the caffeine?' The honest answer used to be 'a glass of water', because every other matcha-coded SKU we offer carries between 30mg (MU) and 120mg (PRIME) caffeine, and the matcha-native palate refuses milk + sugar combinations that pass for evening drinks elsewhere.
Butterfly pea (Clitoria ternatea) is technically not matcha — there is no Camellia sinensis in it. We say so directly. What it is: a caffeine-free flower that micro-stone-grinds to a powder visually indistinguishable from cobalt-azure matcha when whisked, with a faint earthy-floral palate that takes structure beautifully. The Mediterranean theatre is the sage cold infusion: Salvia officinalis picked from the hillside above Bradasevo kitchen the morning of service, cold-infused at 5C for 8 hours, contributes a thin camphor-thyme thread that grounds the floral.
We priced BLU at EUR 10 — the lowest on the live menu — to remove the friction of 'this is a non-caffeine drink, am I paying matcha prices for tea-water?'. The COGS is genuinely lower: no Wako, no adaptogens, butterfly pea at EUR 0.40/g vs Wako at EUR 8/g, sage and lemon are kitchen-foraged. BLU subsidises evening-protocol subscribers staying on the platform past 17:00, when otherwise they'd switch off the brand.
The build.
- 30mlSage cold infusion— fresh Salvia officinalis, 8h cold-infused
- 1 swathLemon zest spritz— expressed over the rim, dropped in
- 250ml chilledBistrica still water
Whisk 3g butterfly pea powder with 30ml warm sage infusion to a smooth cobalt-blue paste. Stir into 250ml chilled Bistrica. Pour into chilled glass or PET. Express one lemon-peel swath over the rim, drop in. Drink within 20 minutes — the blue oxidises slowly toward magenta on contact with citrus pH, that gradient is the visual signature.
Fresh sage forward, faint floral undertone from the butterfly pea, lemon-oil top note from the zest spritz.
Cool, slightly mineral, the butterfly pea contributes structure without sweetness or bitterness.
Long, clean, slight herbal-camphor from sage on the back palate, no caffeine signature.
Light, water-thin, almost saline from the Bistrica minerality. Visual gradient cobalt-to-magenta on contact with the citrus.
The compounds. The mechanism. The dose-response.
Butterfly pea contains anthocyanins (delphinidin glycosides) that contribute the cobalt colour and trace antioxidant activity. Salvia officinalis cold infusion delivers rosmarinic acid and small amounts of carnosic acid — Akhondzadeh 2003 demonstrated mild cholinergic effects on memory in older adults at 60-330mg sage extract daily, but we dose at culinary-aromatic level (sub-clinical) for the palate, not the pharmacology. BLU is explicit: this is a sensory drink, not a nootropic one. Caffeine-free by design.
Sub-clinical. Pharmacology is not the point. The drink replaces caffeine, not adds value to caffeine.

Who orders this. When. Why.
Maja, 34, Kotor Old Town. Done with caffeine by 16:00 because rebuilding sleep architecture after agency burnout. Used to substitute herbal tea bag from a Lipton box. BLU arrives at 19:00 with her standing weekly delivery — same cobalt visual as her morning AOI, zero stimulants, sage from the hillside she walks twice a week. The ritual continues into the evening; the caffeine doesn't.
Marcus, 48, post-charter unwind. Has poured himself a gin at sunset for twelve seasons. BLU is the non-alcoholic alternative he didn't know he wanted — sage and lemon read as gin-coded aromatics, the cobalt-magenta visual gives him something to look at, no caffeine before the 06:00 wake-up. Adds BLU to the BRIDGE pack as the evening SKU. Six other captains have asked since.
Anya's friend, 37, Porto Montenegro, second trimester. Off coffee, off most herbal teas (the obstetrician's list excludes a lot). Butterfly pea is on no exclusion list — no Camellia, no adaptogens, no caffeine, sage at culinary dose is fine post first-trimester. BLU is the drink she can have without checking. She orders one and one for her husband for the pattern of it.
Where it comes from.
matcha terroirNot matcha. Butterfly pea (Clitoria ternatea) is sourced from a Bangkok botanical importer through the same Frankfurt freight line that brings yuzu. EU food-grade certified, no Cambodian or Vietnamese-origin colour-corrected blends. The supplier ships in 5kg vacuum-sealed pouches twice a year.
adriatic elementsSage (Salvia officinalis) grows wild on the hillside above Bradasevo III — the same path that drops to the Bay. Picked the morning of service, cold-infused that day. Lemon from the Tivat Saturday market — small, thin-skinned, locally grown around Bigova when in season, supplemented with Croatian lemons from Dubrovnik nursery stock October-March.
When it works.
- Fresh fish at the table — branzino, orada
- Olive oil and bread
- Yoghurt with honey
- Cucumber on the side
- 17:00-21:00 evening primary
- Late afternoon water replacement
- Wind-down
- Caffeine-free evening
- Pregnant subscribers
- Captain's sunset
Mornings — there's no caffeine here. Save it for evening. Also avoid with hot dairy on the side — butterfly pea pH shifts unpleasantly.
Dominika Miłobędzka frosted-clear small tumbler, 280ml, raw clay foot, hand-cut in Pristina
BLU is built around the visual gradient — cobalt-to-magenta on lemon contact — and that needs transparency to read. Frosted-clear glass with a raw-clay foot lets the colour shift be the focal element. Same hand-cut technique as DRIFT's highball, scaled smaller for the evening water-base format.
Two and a half grams of Wako, one hundred millilitres of soft water at seventy degrees, whisked to a pale jade foam and poured short into a transparent can. Nothing else, on purpose.
Four grams of Wako shaken cold with Yakami yuzu juice, a pinch of Maldon, and Adriatic mineral water, served over a single 5x5cm clear cube. The summer hero. The drink that makes 38C in Tivat survivable.
Ceremonial Wako half-dose (1g), wild olive leaf cold infusion, carob honey pinch, chamomile flower, Bistrica still water. Caffeine ~25mg — lower than a single espresso third. The morning meditation drink for the subscriber who wants the ritual before the focus.
