Moisture Content and Start Temperature

Green coffee moisture content can be used as one input when choosing a roast start or charge temperature. Community guidance from denis6004 suggested treating the roast according to the coffee’s moisture content: lower-moisture coffees can use a colder start, while higher-moisture coffees can use a hotter start. source

If You Do Not Have a Moisture Meter

If you do not have a moisture meter, denis6004 advised asking the importer for the coffee’s moisture content. Treat importer-provided values as useful starting information, while remembering that storage and time can affect the actual moisture of the coffee by the time it is roasted. source
