Abstract

Coffee brewing cycle time is improved by contacting roasted ground coffee with a brief interval of steam, e.g. 3 seconds. The steam is preferably introduced prior to contact with brewing water and may be followed by a brief interval of pause prior to introducing the water. Steam and water are preferably introduced under a moderately elevated pressure. Improvements in appearance, color, flavor, aroma and yield can be achieved along with reduced cycle time.
