A logbook for the ritual of coffee

THE BREWLedger

The pour becomes data

Every drop,
distilled into memory.

As the water falls, the Ledger listens. Weight, flow rate, and time are captured mid-pour and folded into a brew print you can replay, compare, and refine — cup after cup.

  • Live scale sync

    Bluetooth brew-print, drawn as you pour

  • Per-method interfaces

    V60, espresso, immersion, cold brew

  • Numbered entries

    Every cup stamped into your Ledger

Seven instruments, one ledger

    The Bloom

    50g of water, spiralled slow. The bed swells and exhales — forty-five seconds of quiet chemistry.

  2. 0:45→ 150g · spiral

    First Pour

    A steady spiral to 150g. The gauge tracks every gram against the target curve in real time.

  3. 1:30→ 250g · 93°C

    Second Pour

    Centre-weighted, up to 250g. Water holds at 93°C — the Ledger notes the kettle never wavered.

  4. 2:00→ 320g · 1:16

    Drawdown

    One gentle swirl to level the bed. The stream thins; the curve flattens toward 320g.

    Done. Rate the cup, write the note, and the session is stamped into the Ledger — forever replayable.

Inside the Atelier

The Shelf

Your beans, aging gracefully.

Every bag tracked from roast date to last gram. Freshness windows, rest timers, and the best brew each bag ever produced — all at a glance.
