The present disclosure is generally related to systems and methods for producing liquid extracts from a solid raw material, as well as related equipment. Certain aspects are related to the production of multiple liquid extract products using a single system by adjusting one or more displaceable fluidic pathway segments within the system to switch between first and second (or more) extraction configurations. In certain embodiments, a first liquid extract can be produced when the displaceable fluidic pathway segment is in a first configuration, and a second liquid extract (different from the first liquid extract) can be produced when the displaceable fluidic pathway segment in in a second configuration (different from the first configuration).

A coffee processing apparatus (100, 200, 300) is disclosed that comprises at least one of a grinding stage (110) for grinding coffee beans (10) into ground coffee beans (20); and a brewing stage (140) for brewing coffee from ground coffee beans; the coffee processing apparatus further comprising a sensor (150) arranged to sense a total concentration of volatile organic compounds released by said coffee beans or ground coffee beans; and a controller (160) responsive to said sensor and arranged to control said grinding stage and/or said brewing stage as a function of said total concentration. Methods of controlling such a coffee processing apparatus are also disclosed.

A method of forming a ready-to-drink coffee product includes contacting a first ground coffee composition with water having a temperature of less than 10° C. for at least 16 hours to form a first cold brew concentrate; mixing the cold brew concentrate and water to form a mixture; heating the mixture to a temperature of less than 100° C. for less than 1 minute to form a pre-fill coffee composition; pouring the pre-fill coffee composition into a cavity; concurrent to pouring, increasing a temperature of the pre-fill coffee composition to at least 82.2° C. and holding the pre-fill coffee composition at the temperature of at least 82.2° C. for at least 30 seconds to form a filled coffee composition; and cooling the filled coffee composition to ambient temperature within the cavity to form the ready-to-drink coffee product. A ready-to-drink coffee product system is also disclosed.

A coffee bean shaving process is utilized herein to produce shaved coffee bean products, such as coffee flakes, coffee shavings, and coffee slices, which may comprise clean and smooth faces and rough edges. Due to the shaving process described herein, the shaved coffee bean products may be produced with larger and fewer surfaces, thereby yielding a coffee product with greater surface area to volume (SA/V) ratios, particularly when compared to coffee grounds produced by conventional burr grinders. Consequently, by optimizing these SA/V ratios, it has been observed that one can maximize the coffee making potential of a coffee bean and reduce the SA/V variances between particles, thereby creating more consistent results.
