The present disclosure relates to methods and/or techniques for the production of cold-brew coffee extracts, which enable continuous and rapid extraction and simultaneously improved yield of aromatic constituents and nutritionally beneficial components (e.g., polyphenols, antioxidants, and/or sugars) when compared to known cold-brew techniques. The method enables continuous processing within a shortened time frame, while producing extracts with improved flavour yield, intensity and body. In addition, cold-brew coffee extracts and instant powders prepared by said methods are described.

The present invention relates to a dried coffee powder obtainable by a process comprising membrane filtration of a low temperature extract of roasted and ground coffee beans to reduce the concentration of low molecular weight components and drying the filtered coffee extract.

A method of forming frozen beverage blocks from a liquid beverage. The method may include introducing a beverage into a hot beverage reservoir of a beverage receiving subsystem to initiate the process. Next, the beverage may flow from the hot beverage reservoir of the beverage receiving subsystem into a cooling subsystem. The flow from the hot beverage reservoir into and through the cooling subsystem may be done entirely via gravity. Cool air may be blown across the cooling subsystem to cool the beverage as the beverage flows through the cooling subsystem. Upon the temperature of the beverage being measured at or below a predetermined lower threshold temperature, the beverage may be permitted to flow, via gravity, from the cooling subsystem into a cool beverage reservoir of a freezing subsystem. The freezing subsystem may be configured to convert the beverage from a liquid into frozen beverage blocks.

A coffee milling process comprising the steps of: a) introducing particles of a roasted coffee precursor into a milling chamber; b) introducing particles of soluble coffee into the milling chamber; c) jetting a gas into the milling chamber to mobilise the particles of the roasted coffee precursor and soluble coffee; d) thereby producing a milled and blended coffee product by comminuting the particles of the roasted coffee precursor by self-collision of the particles of the roasted coffee precursor and by collision of the particles of soluble coffee with the particles of the roasted coffee precursor within the milling chamber. Processes and products incorporating milled and blended coffee products are also described.
