ABSTRACT:
A process for preparing infusions of aromatic substances such as coffee and tea comprising the steps of confining a predetermined mass of discrete particles of said substance in a closed water permeable supporting and filtering container of predetermined dimensions, and repeatedly submerging said container with the substance therein within a predetermined volume of hot water, the relationship of the container dimensions and the mass being such that when the container is submerged in hot water the thickness of the mass therein is maintained less than a predetermined critical thickness of irreversible self-compactness, the repeated submerging and withdrawing of the container effecting repeated admission and drainage of hot water from the container thereby promoting successive states of decompaction and reversible compactness of the particles in the confined mass, until a desired degree of concentration of the infusion is attained in the body of water, and containers for carrying out the process.
