Coffee system

A method of extracting a consumable material from a solid raw material comprising acts of:

• providing a quantity of solid raw material in an enclosed container;
• supplying an aqueous solvent to the enclosed container and the quantity of solid raw material, thereby forming a combination of the solvent and the solid raw material;
• pressurizing the enclosed container and the combination of the solvent and the quantity of solid raw material to a pressure level of at least about 50 psig;
• exposing the quantity of solid raw material to the pressurized solvent and maintaining the pressure level for a desired period of time under non-flow conditions;
• and
• depressurizing the enclosed container and the combination of the solvent and the quantity of solid raw material from the pressure level by opening an outlet valve on an outlet line of the enclosed container and establishing a flow of an aqueous extract from the quantity of solid raw material through the outlet line, which flow is driven, at least in part, by the pressure within the enclosed container.

A method of extracting a consumable material from a solid raw material comprising acts of:

• providing a quantity of solid raw material in a surrounding gaseous environment at a first pressure;
• supplying an aqueous solvent at a second pressure substantially different than the first pressure to the quantity of solid raw material, thereby forming a combination of the solvent and the solid raw material;
• pressurizing the combination of the solvent and the quantity of solid raw material to a pressure level of at least about 50 psig;
• exposing the quantity of solid raw material to the pressurized solvent and maintaining the pressure level for a desired period of time under non-flow conditions;
• and
• establishing a flow of an aqueous extract from the quantity of from the quantity of solid raw material.
