# Pour-over timer

Set your dose and ratio, then follow the steps with big numbers you can read from the kettle.

## How the schedule is built

The water is your dose times the ratio: 22 g at 1:18.2 makes 400 g, the same as the SCA’s guide for a two-cup pour-over. The bloom uses about 2¼ times the coffee’s weight in water (that guide uses 50 g for 22 g) and lasts 30 seconds unless you change it. The rest of the water is split into equal pours that start at even intervals, leaving the last stretch for the drawdown, so the brew finishes around your total time.

Each step shows what the scale should read when you finish pouring, not how much to add, so you can keep the scale tared to the empty dripper and just pour to the number. Press Start as you begin the bloom. With the chime on, you hear two soft notes at each new step and three at the end. While the timer runs, the page asks your browser to keep the screen awake; if it can’t, a note says so. Real brews drain faster or slower depending on the grind, so treat the drawdown time as a target and grind finer or coarser next time if you are well off it.

## Questions

**Why bloom the coffee first?**

Freshly roasted coffee holds gas that bubbles out when it first gets wet. Wetting all the grounds and waiting about 30 seconds lets that settle before the main pours, which is the step the SCA’s pour-over guide starts with.

**How many pours should I use?**

Three is a comfortable start for a one- or two-cup dripper. More, smaller pours keep the water level lower and steadier; fewer pours are simpler. The total water stays the same whichever you choose.

**Does the timer work with the screen off?**

The timer keeps counting from the moment you pressed Start, so it is right again when you come back. While it runs it asks the browser to keep the screen on; chimes need the page to stay open.
