Coffee roaster having multiple roasting stages

A method of roasting coffee beans in a roasting chamber of a roasting apparatus, comprising the steps of:

• controlling a temperature of an airflow supplied to a roasting chamber to follow a predetermined temperature curve, said following of said temperature curve including;
• roasting the beans in a first stage in which a roasting temperature is set to a first predetermined level for a first predetermined time period;
• roasting the beans in a second stage in which said roasting temperature is set to a second predetermined level that is higher than said first predetermined level,
• said second stage including a plurality of stages including a current stage in which said roasting temperature is set to a current predetermined level for a current predetermined time period and a subsequent stage in which said roasting temperature is set to a subsequent predetermined level that is higher than said current predetermined level for a subsequent predetermined time period.

A roaster for roasting coffee beans comprising:

• a roasting chamber having a top and a bottom for holding coffee beans when the beans are being roasted;
• a cover seated on said top of said roasting chamber;
• a base on which said bottom of said roasting chamber is seated;
• an inlet airflow control assembly provided on said base for controlling an amount of ambient air entering said base;
• means provided in said base for supplying an airflow into said roasting chamber;
• and,
• control means for controlling said airflow supplying means to generate a roasting temperature inside said roasting chamber.
