Provided is a coffee composition having an excellent hypotensive effect. The coffee composition has the following components (A) and (B): 0.01 to 1 wt. % of chlorogenic acids (A), less than 0.1 wt. %, based on the weight of the chlorogenic acids, of (B) hydroxyhydroquinone.

A method of brewing a beverage, such as freshly brewed coffee, in an electrical, automatic beverage brewer (10) with a rotatable mixing chamber (12) for mixing water (109) from a hot water tank (28) with dry beverage ingredient (108) having a closed top (7) and an open bottom (3, 66) to which is releasably mounted a brew basket (14) with an open top (19) for fluid communication with the mixing chamber (12) through the open bottom (3, 66). Before mounting, the brew basket (14) is loaded with a filter (105) and dry beverage ingredient (109). The mixing chamber (12) with the brew basket (14) attached is then automatically turned upside down (FIG. 6) to dump the dry beverage ingredient (109) out of the filter (105) and onto the closed top (7) of the rotatable mixing chamber (12). A preselected amount of water (109) is then infused into the mixing chamber (12) to a level beneath the open bottom (3) and filter (105) and onto the dry beverage ingredient (109) for mixing therewith. After a preselected mixing time period is passed the mixing chamber (12) and mounted brew basket (14) is automatically turned right side up to pass the beverage (110) through the filter (105) and out of the drain hole (90) of the brew basket (14). After the mixing chamber (12) has been returned to an upright position, pressurized air (44, 46, and 48) is automatically injected into the mixing chamber (12) to hasten the passage of beverage (110) through the filter (105) and out of the drain hole (90).

Provided is a coffee composition having an excellent hypotensive effect. The coffee composition has the following components (A) and (B): 0.01 to 1% by weight of chlorogenic acids (A), less than 0.1% by weight, based on the weight of the chlorogenic acids, of (B) hydroxyhydroquinone.

The present invention provides refined roasted coffee beans having a Hunter L value of 10 to 30 and a hydroxyhydroquinone content of not higher than 30 mg / kg by contacting an aqueous solvent with raw material roasted coffee beans. The invention also provides a process for producing refined roasted coffee beans, which includes contacting raw material roasted coffee beans having a Hunter L value of 12 to 35, with coffee bean-derived extract-containing water selected from water containing an extract derived from roasted coffee beans having a Hunter L value of 40 or more and water containing an extract derived from raw coffee beans.

The present invention provides a method for producing roasted coffee beans useful as a starting material for a coffee beverage having rich body, suppressed in unpleasant taste and reduced in the amount of hydroxyhydroquinone. The method for producing roasted coffee beans of the present invention includes placing starting material roasted coffee beans in an airtight container and subjecting the roasted coffee beans to a heat treatment at from 100 to 160° C. under humidified conditions.
