ETHANOL // DRINK CHEMISTRY HUD

ETHANOL

Drink chemistry, demystified.

Every pour logged as grams of ethanol and milligrams of congeners: the trace compounds behind a drink's color, aroma, and character. Counts, elapsed time, and a pace read against a fixed rule that learns from prior nights. No sliders. No guesses. A brutalist HUD for what is in the glass.

AZEO // STATUS LINE
LINES AND TRACE FROM THE APP
  • Welcome to ETHANOL. I'm Azeo.
  • I'll drop occasional thoughts and generally hang around while you use the app.
  • I'm mostly benevolent.
  • A still is patience with a copper roof.
  • I have a favorite isomer. I'm not saying which.
  • Ice floats. The Arctic is on the rocks.
  • Bitters are the shadow that lets the light read.
  • I'm not antisocial. I'm a noble gas.
  • Cheers to good chemistry.
AZEO // THE VOICE IN THE CABINET

One line, then the trace

Azeo is the instrument that came with the app and has opinions. One line of dry wit at the top of STATUS (chemistry, bar lore, the lime thief, the vermouth open since June), then back to a quiet green trace. It roasts drinks and trends, never the person holding the phone, and is never impressed by a quantity.

  • A new line on each return to STATUS
  • A tap on the trace brings the next one
  • A long press opens AZEO CHAT
STATUS at rest with Azeo's line at the very top reading “That barrel was a tree for a hundred years before it was a barrel for twelve.”, above tiles reading 27 formulations makeable and 11 bottles in the bar, the featured formulation Royal Bermuda Yacht Club with its spec and an on shelf 2 of 4 tally, a 7-day strip of 06 sessions and 23 drinks, and the START SESSION key

System

[ 02 // WHAT IT TRACKS ]
01

Session Scope

Two traces, both running totals: cumulative grams of ethanol logged, cumulative milligrams of congeners. Counts what was poured, nothing else.

02

Pace Read

Steady or heavy. A fixed rule holds from the first pour; personal history joins it once a few sessions are on record.

03

Telemetry

Drinks, sessions, calories, and spend across 7 / 30 / 90 / 365-day windows. Peaks marked, deltas tracked.

04

Flavor Fingerprint

The congener profile of every pour. The chemistry behind the taste, charted.

05

Menu Scan

A photograph of any drink menu, read into a list of names, prices, and categories. Each item opens to its molecules, strength, and congener load. 5 to start, then 3 a month.

06

The Lab

206 cocktail formulations, custom builds, and favorites. One formulation featured each day.

07

Compendium

41 signature molecules across six families, unlocking pour by pour: gin's terpenes, tequila's methyl anthranilate.

08

The Map

Venues pin to the map, with the night's route drawn between stops. The picker learns the usual spots and suggests the likeliest for the hour.

09

Wrist + Lock Screen

Count and pace mirrored to Apple Watch, widgets, and the Dynamic Island. From the Lock Screen, a widget, or the Action Button, one tap logs a drink.

10

Bar Inventory

What can be made from what is on the shelf. Bottle labels scan straight into stock.

11

Monthly Wrapped

The month compressed to a single telemetry sheet, alongside k-anonymous benchmarks, never an individual.

12

Insights

Pattern, health, and spend signals surfaced from the data. Statistics, not a model. Observed, not nagged.

Surfaces

[ 03 // THE INSTRUMENT ]
TIMELINE // EVERY SESSION, KEPT

A journal of every session

Each session becomes one tile: the day, the count, the drink of the night drawn in its glass, the venue. Months stack newest first, and a tile opens the session's own page with its scope, venues, photos, and cost. Telemetry sits one segment over: drinks, sessions, calories, and spend across 7, 30, 90, and 365 days.

  • One tile per session, by month
  • The drink of the night, drawn in its glass
  • Telemetry: 7 / 30 / 90 / 365-day windows
TIMELINE: a headline reading 103 days, 42 sessions, 05 venues and 41 of 41 molecules, above October 2026's eleven session tiles, each a day of the month, a drink count, the night's drink drawn in its glass and the venue, Kumiko or The Violet Hour
TIMELINE // OCTOBER 2026
INDEX // THE CHEMISTRY OF THE GLASS

The molecule behind the drink

Every pour unlocks the compounds inside it, filed in a periodic table of 41 molecules across six families: structure, formula, mass, and where each one turns up. A field guide to the chemistry, built one drink at a time.

  • 41 molecules across 6 families
  • Structure · formula · mass · sources
  • Unlocks pour by pour
The INDEX: a headline reading molecules 41 of 41 above a periodic table of element cards, each with its number, formula and turning ball-and-stick structure: under alcohols, 01 ethanol and 02 2-phenylethanol; under acids, 03 acetic acid, 04 lactic acid and 05 malic acid

FORMULATIONS // FLAVOR FINGERPRINT

206, built to spec

A catalog of formulations, each broken down to the active congeners that define its taste, with reagents, method, and scaling. All 206 are free.

  • 206 formulations, none gated
  • Active-congener fingerprint
  • Reagents · method · scaling
French 75 formulation: the alpha-pinene, alpha-thujone and citral structures drawn above the name and attributed to the gin, the absinthe and the lemon, a coupe · 16% ABV · ~142 kcal spec line, a favorited mark, a provenance note placing it at Harry's New York Bar in Paris in the WWI era, an abstract naming the chemistry of the build, and a batch scale control
FORMULATION // FRENCH 75
THE LAB // THE BENCH

The shelf, indexed

Formulations, the compendium, the home bar, favorites, and taste evolution, each a live instrument on one bench. A stocked shelf resolves into a count of what can be built from it, and a craft key builds a new formulation from scratch.

  • Five live instruments, one bench
  • Custom builds + favorites
  • Taste evolution, charted
The LAB tab: a wall of instrument tiles reading 27 formulations makeable under a martini glass, a 41 of 41 compendium with a turning molecule, a bar of 11 bottles drawn as outlines, 08 saved favorites listing Last Word, Paloma, French 75, Negroni and Daiquiri, and a taste evolution meter over 13 drinks, above the CRAFT FORMULATION key

MY BAR // THE SHELF

What the shelf can make

The home bar, bottle by bottle: typed in, or read off the cabinet by a camera pass along the shelf. The shelf resolves into what it can build, and the one bottle that would open the most new formulations is named at the top.

  • Built from what is stocked
  • Cabinet scan, bottle by bottle
  • One reagent short: the next bottle, named
MY BAR: Azeo's line reading “Adding rye whiskey to your bar would open up 3 formulations.”, a bar of 12 reagents, a SCAN CABINET control and a field to add bottles by name, a one reagent short panel naming rye whiskey at +3 formulations, and the shelf listing Aperol, Bombay Sapphire, Campari, Cointreau and dry vermouth with their stock levels
MY BAR // ONE REAGENT SHORT
THE WRIST // APPLE WATCH

The count, at a glance

Count, pace and elapsed time on the wrist, under the night's scope as the phone draws it. Water and drinks log in one tap each, the last round repeats by name, and TONIGHT lists every glass. No phone required.

  • Count · pace · elapsed, at a glance
  • + WATER and + DRINK, one tap each
  • The last round, repeated by name
ETHANOL on Apple Watch mid-session at Corner Bar: the night's scope with its ethanol and congener traces, a count of 03 in green beside NEGRONI, STEADY and 01:41 elapsed, a tally reading H2O 01, DRINKS 03, and + WATER and + DRINK keys
THE WRIST // APPLE WATCH
IPHONE DUO // THE SPREAD

Two pages, one instrument

Opened like a book on iPhone Duo, STATUS spreads across both pages: the scope, the count, and the keys on the left; the night's ledger, water, and the safety pair on the right. LAB, TIMELINE, and VAULT open as a list on one page and its detail on the other. Folded, the cover keeps the phone's layout.

STATUS in session on iPhone Duo's inner display, opened as a two-page spread: on the left, Azeo's line, a scope charting 31 grams of ethanol against 895 milligrams of congeners, a count of 03 drinks at The Violet Hour and the + DRINK and SCAN MENU keys; on the right, the night's ledger of a pilsner, a boulevardier and a negroni, a collect specimen control, a water tally, the don't drive after drinking notice, the GET HOME key and END SESSION

THE POSTURE

Counts, not verdicts. The HUD logs what was poured (grams, congeners, minutes) and scores no one, clears no one, and never calls a drive safe. Any amount impairs. The HUD reports. The operator decides.
