Abstract
A brewing apparatus with a brew basket for holding ingredients in particulate form that contain soluble flavorants delivers a predetermined amount of hot water to a spray head positioned above said brew basket. The spray head has a multiplicity of openings positioned and configured in such a manner that the hot water is sprayed uniformly over the entire surface of the ingredients at a predetermined rate thereby wetting substantially all of the particles of the ingredients and uniformly extracting said solubles.
Claims9
A brewing apparatus having a brew basket for holding ingredients in particular form that contain soluble flavorants, a heating tank for heating and holding water, and a hot water delivery system for delivering hot water from said tank to said brew basket, said apparatus including a spray head in liquid communication with said water delivery system and positioned above said brew basket, said spray head having a bottom wall in which a first set of openings is positioned to spray water at predetermined rate over a central surface region of the underlying ingredients and a second set of openings is positioned outside of said first set of openings to spray water at said predetermined rate over a remainder surface region of the underlying ingredients, said bottom wall and each of said second set of openings collectively structured so as to distribute water through said second set of openings in a fan shaped pattern over said remainder region thereby wetting substantially all of the particles of the ingredients and uniformly extracting said solubles.
A method of brewing a coffee beverage from ground coffee positioned in a filter basket and delivering the beverage to a decanter comprising the steps of
- positioning ground coffee in a filter basket over the decanter;
- delivering a predetermined amount of hot water to a spray head positioned over the filter basket;
- causing the hot water to be distributed at a predetermined volume rate over a central surface region of the underlying ground coffee in the filter basket;
- and
- causing the hot water to be distributed and sprayed in a fan shaped pattern at essentially the same predetermined volume rate over an outer periphery surface region of the ground coffee.
