Abstract
A method of making coffee in a drip-type coffee maker includes introducing steam into coffee grounds, and passing heated water through the coffee grounds to infuse the water. A coffee maker includes a second water passage in which the flow of water is controlled so that it is converted into steam for delivery to the brew basket. The steam enters the brew basket below the level of any coffee grinds in the basket, and causes a substantially helical steam flow path in the grinds.
