What Is Charge Temperature in Coffee Roasting?

Definition

The measured temperature at the moment green coffee enters the roaster.

Why it matters

It establishes the initial thermal conditions and strongly influences early heat transfer without, by itself, defining the whole roast.

How it is measured or recognized

Record the relevant machine or environmental reading at charge together with batch size and preheat state.

Roasting tip

Compare charge settings only on the same machine with consistent probes, batch size and between-batch preparation.
