Light roast timer for clean, repeatable coffee

Roast planning

Use light roast timer as part of a repeatable roasting routine

The value of a roast timer comes from capturing decisions while the roast is happening, then turning those decisions into a profile you can compare later. Before charging the beans, choose a target roast level, batch weight, expected first crack window, and a rough drop target. During the roast, record the events that affect flavor: turning point, dry end, first crack, development time, drop time, and any temperature notes you can capture without distracting yourself from safety.

After the batch cools, add context while it is still fresh. Note whether first crack arrived earlier or later than expected, whether the roast coasted or accelerated near the end, and what you would change on the next attempt. A short note such as "drop ten seconds earlier" or "stretch drying by thirty seconds" is often more useful than a long paragraph written days later. When you taste the coffee, connect the cup result back to the timing instead of keeping those observations separate.

Coffee Roasting Timer is designed for that loop: plan the roast, mark the important moments, save the record, then use history to decide the next adjustment. The goal is not to force every coffee into the same profile. It is to make each roast easier to understand, so changes in sweetness, acidity, body, and roast flavor can be traced back to the choices you made at the roaster.

For a practical routine, review the previous roast before starting the next one and choose only one or two changes. Changing charge temperature, heat setting, airflow, batch size, and drop time all at once makes the result hard to read. A cleaner approach is to keep most variables stable, adjust the timing or endpoint you care about, and write down why you made that choice. Over several batches, those small records become more useful than memory because they show what consistently improved the cup and what only sounded good during the roast.

A useful saved record should answer three questions: what profile did you intend to run, what actually happened minute by minute, and what should change next time. When those answers are attached to the same roast, every batch becomes easier to repeat or deliberately improve.
