Roast Planner

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.

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.
