Brewing

The Brewing tab is the live brew-day surface — the screen you keep open at the kettle. A countdown timer at the top drives the session step by step; below it a status strip holds your targets, the brew sheet lists every step in order, and a Readings card and Brew day notes timeline capture what actually happened. Unlike Planning, most of what you touch here is measured, not prepared.

Readings and notes save the moment you log them. The status strip's strike temp, mash pH, and pre-boil gravity are read-only targets from the recipe — log your actual measurements in the Readings card.

Brew-day timer

The console at the top of the tab runs one step at a time. The top line reads Step N of M and a status — not started, in progress, or paused — with the active step’s name beside it.

Readout

Countdown: the large mm:ss is the time left on the active step. An untimed step (no set duration) shows ——:——. The final seconds turn the readout amber as a warning.
elapsed: time counted on the active step so far.
next: the step that will activate when this one finishes — or finish on the last step.
total: the active step's full duration.
Progress bar: fills from 0 to 100% as the step's time elapses.

Controls

Start / Pause / Resume: the primary button. With nothing running it reads Start and activates the first step; while running it pauses; while paused it resumes. Disabled when the sheet has no steps.
Prev step: steps back to the previous step and restarts its timer. Disabled on the first step.
Next step: marks the current step done and activates the next — the same advance the timer makes at 0:00. Disabled on the last step.
Reset: restarts the current step's timer at 0:00. Disabled when no step is active.

Every step in the sheet is in one of three states, which the timer and the brew sheet share:

State	Meaning
Upcoming	Not yet reached. The sheet shows its step number and an eta time.
Active	Running now — the timer counts it down. The sheet labels it now.
Done	Completed. The marker shows a check and the sheet labels it logged.

How the timer keeps time

The countdown is reconstructed from the clock and stored on the server, so a refresh, a closed laptop, or a second device all pick up the exact same remaining time — nothing is lost. When a step hits 0:00 the timer advances once on its own: it marks the step done, activates the next one, restarts at 0:00, plays a chime, and announces “[step] complete”. The last step simply stops the timer. If the network hiccups at the moment of advancing, the step parks at 0:00 — tap Next step to move on.

Brew day status

A five-cell strip under the timer:

Brew started: the clock time the brew began — set when you first start the timer.
Elapsed total: wall-clock time since the brew started, with the current step N of M below it.
Strike water: read-only target strike / mash temperature.
Mash pH: read-only target mash pH.
Pre-boil gravity: read-only target pre-boil gravity.

Brew sheet

The left card lists every step of the brew in order. The header counts progress (for example, 2 of 9 done).

Marker: the circle at the left of each row. It shows the step number, or a check once done. Tap it to change the step's state: an upcoming step marks done, the active step advances to the next, and a done step goes back to upcoming.
Time: each row is prefixed eta (upcoming), now (active), or logged (done), with the step's time beside it.
Name + description: the step name with a short description; the description hides while a done step is collapsed.
Stage chip: a coloured tag for the step's stage (see below).
Additions: ingredients dosed at that step — name and amount — for example hops at a boil step.

The stage chip names what kind of step it is:

Chip	Stage
mash	Mashing in and mash rests.
boil	The boil and boil additions.
whirlpool	Post-boil whirlpool / steep.
chill	Chilling the wort.
transfer	Moving the wort to the fermenter.

Done steps tidy themselves away. Once steps are complete the header offers Show N done to expand them all (and Collapse done to hide them again). A single done step that has additions also carries a small chevron to peek at its details without expanding the rest.

Readings

The Readings card on the right logs your actual measurements over the brew. Each metric gets one row; log the same metric more than once and the row keeps the history.

Row summary: the metric name, how many readings you've logged, a trend arrow (▴ rising / ▾ falling) across them, and the current value.
Delta vs target: a dot and signed difference against the recipe target — green when the reading is within tolerance, accent when it's out.
History: click a row to expand its readings (time and value). Click set current on any entry to pin it as the row's current value instead of the latest.

Log a reading. The row at the bottom takes a time (now, or an HH:MM you type), a metric, and a value, then Log. The metric picker covers Mash temp, Mash pH, Pre-boil gravity, Pre-boil volume, OG (post-chill), Post-boil volume, and Strike temp.

Brew day notes

A running timeline of timestamped notes for anything the readings don’t capture — a stuck sparge, a boil-over, a smell worth remembering. Type in the box at the bottom and press ⌘ + ↵ (Ctrl + Enter) to log; each note is stamped with the time.

How to run a brew day

1Press Start on the timer to activate the first step.
2Work the brew sheet — let each step auto-advance at 0:00, or use Next step (or tap a row's marker) to move on manually.
3Log your strike temp, mash pH, gravities, and volumes in the Readings card as you take them, and check each against its target.
4Drop a note for anything unusual.
5When the wort is in the fermenter, advance the batch to 03 · Ferment.
