An improved coffee brewer and brewing method are provided for producing brewed coffee with improved flavor. The coffee brewer includes a brew basket having jet ports connected to a source of heated water and positioned to deliver hot water streams into the brew basket at a location beneath the level of coffee grounds contained therein. These hot water streams turbulently agitate and stir the coffee grounds to produce a substantially fluidized bed of water- borne coffee grounds for improved flavor extraction and enhanced aroma, This fluidized bed is directed against one or more mesh filter elements forming a wall portion of the brew basket for outward passage of the thus-brewed coffee which is then directed into an underlying carafe or the like. In one preferred form, a portion of the brew basket may incorporate a window to permit visual observation of the fluidized bed therein.

L'invention concerne un infuseur à café amélioré et un procédé d'infusion permettant de produire un café infusé présentant un goût amélioré. Cet infuseur à café comprend un panier-filtre possédant des orifices d'éjection reliés à une source d'eau chaude et se trouvant en dessous du niveau du marc de café contenu dans celui-ci. Les jets d'eau chaude agitent et remuent de manière turbulente le marc de café, d'où la production d'un lit sensiblement fluidisé de marc de café en suspension dans l'eau permettant d'obtenir une extraction de goût améliorée et un meilleur arôme. Ce lit fluidisé est dirigé contre un ou plusieurs éléments filtrants à tamis constituant une partie de la paroi du panier-filtre en vue du passage vers l'extérieur du café infusé, lequel entre ensuite dans une verseuse sous-jacente ou analogue. Selon une variante préférée, une partie du panier-filtre peut comprendre une fenêtre permettant de voir le lit fluidisé.
