A method and apparatus for extracting compounds from raw materials with an extraction column is provided. The control and manipulation of pressure exerted and contained within the extraction vessel or column may be vital in obtaining a certain flavor profile or intensity of the effluent extracted from the raw materials. As such, the method may include directing a flow of pressurized solvent into a base of the extraction column and utilizing the flow of pressurized solvent to create a pressure gradient applied to the raw materials. The method may further include compressing the raw materials with hydraulic compression. As the raw materials become further compressed, frictional heating may result allowing most, if not all, of the volatile aromatic heat sensitive compounds and constituencies to be extracted depending on the pressure strength applied to the raw materials. As such, manipulating the pressure gradients for each extraction process allows for distinct and specific flavor profiles to be extracted from the raw materials.
