# Plan the roast before you light the burner.

A structured worksheet that computes first crack, development, and drop from your bean — then keeps the plan next to what actually happened.

## Time Ledger

1.4 First crack anchor 9:30
5.6 Bean-condition refinement+0:10
4.3 Development base 2:15
Drop time 11:55

## Built around the worksheet, not a generic form

Every field ties back to the same time-ledger math professional roasters already use on paper — now it computes itself.

### The Time Ledger

Anchor first crack by cultivar, then let refinements, bean condition, and batch size sum into a plan you can defend.

✓

### Sanity checks

Drying, Maillard, and development ratios validated against known bands before you roast.

### Plan vs. actual

Log milestones at the machine, attach an Artisan .alog reference curve, and see plan against reality.

## Three steps, every roast

### Describe the coffee

Cultivar, process, bean condition — the worksheet pulls in the right reference numbers automatically.

### Review ledger & checks

Watch first crack, development, and drop compute live, with every ratio checked against known-good bands.

### Roast and record

Log milestones as you go, then compare against an Artisan reference curve after the roast.

## Plan your next roast properly.
