Provided is a novel roasting method that is effective for improving the flavor of roasted coffee beans. The present invention provides a method for producing roasted coffee beans, including a step of roasting coffee beans, wherein a ratio of lightness (lightness ratio) of the coffee beans is 0.65 or more, and a temperature increasing rate of a roasting temperature is retained at −0.15° C./second to 0.15° C./second.

Method for producing roasted coffee beans and roasted coffee beans

A roasted plant extraction apparatus is provided which is capable of selectively reducing excessive bitterness in an extract liquid obtained by water extraction from a roasted plant raw material while preserving desirable flavor ingredients and body. A beverage extraction apparatus includes a granule containing part adapted to contain granules for extraction of a beverage, a pouring device for pouring an extraction solvent into the granule containing part from a first direction, and a collecting device for collecting an extract liquid extracted by means of the extraction solvent. The granule containing part comprises a detachable restraining member for placing the granules in a substantially sealed state. The beverage extraction apparatus further comprises a rotary mechanism for rotating the granule containing part.
