Tap a wine. Find the bottle.
A light breathes gently over the exact column holding it — colour-coded by type, so a Barolo glows red and a Champagne glows pale blue. No crouching, no headlamp, no reading labels upside down.
CellarLume turns an LED-equipped wine rack into a smart cellar. Tap a bottle on your phone and a light breathes over the exact column holding it — and that’s the least interesting thing it does.
The iOS app is free. On TestFlight now, App Store in October 2026.

Inventory apps are a solved and boring problem. CellarLume’s real trick is that the rack itself becomes the interface.
A light breathes gently over the exact column holding it — colour-coded by type, so a Barolo glows red and a Champagne glows pale blue. No crouching, no headlamp, no reading labels upside down.
One tap lights everything that matches — a grape, a food pairing, a country. Countries wave their flag in LEDs across the rack, which is a ridiculous thing for a wine rack to do, and exactly why it’s there.
The heat map paints the wall at once: green means drink it now, amber means soon, red means you waited too long, blue means it’s still sleeping. Ten seconds tells you what six spreadsheets wouldn’t.
The light races the rack, slows, and lands on tonight’s bottle. It settles arguments and it’s a very good party trick, in that order.
Build a tasting flight and the wall pulses the pouring order. Start the decant timer and the wall fills as the wine breathes — glance over from the kitchen and you know how long is left.
Open a bottle and a webhook fires the moment it’s logged. In the reference install that drives a split-flap display running a four-act show: what was opened, where it came from, what to eat with it.
Addressable LEDs run along the rack rails, one per column. A drill guide and stocking map come with the kit so the holes land where they should the first time.
An ESP32-based controller joins your home Wi-Fi and holds the whole catalog itself. It is the only server involved. There is no other server.
Add wines in the app, or arm a bottle and tap NFC tags along the rack to shelve a case without touching the screen once.
The catalog lives on the controller on your own network. There is no account to make, no server of ours to trust, and nothing to keep paying for. If our website vanished tomorrow, your wall would light up exactly the same tonight.
The controller kit and DIY licences open later this year. Leave an email and you’ll hear once — when there’s something to buy.
