Device and methods for brewing a beverage from a heated liquid chamber are disclosed in which the kinetic energy of rising air bubbles injected into a water heating chamber or delivery tube entrains the liquid in the water heating chamber to a delivery spout.

In pour-over brewing, a vessel containing water can be suspended over a brew basket so that the water can drain, under gravity, into the brew basket and onto the coffee, and the water level in the brew basket is used to regulate the flow of water from the vessel. A vessel that is closed, other than the mouth thereof, and containing brew-heated water, is suspended over the brew basket so that the water can drain from the mouth of the vessel into the brew basket and into the ground coffee to brew liquid coffee, which drains into a container. Rising of the water in the brew basket causes interruption of drainage of the water from the mouth of the vessel into the brew basket, and lowering of the water in the brew basket causes resumption of drainage of the water from the mouth of the vessel into the brew basket.

A coffee extraction apparatus includes: a grinder grinding whole beans into coffee powder having a preset size or less and discharging the coffee powder, a grinder inlet defined at a first side of the grinder to introduce the whole beans to the grinder, a grinder outlet defined at a second side of the grinder and discharging the coffee powder, and a first extractor. The first extractor includes: a receiver inlet that faces the grinder and that receives the discharged coffee powder, a filter part receiving the coffee powder through the receiver inlet and extracting coffee liquid by rotating the coffee powder with water of a first temperature, the first temperature being equal to or lower than 25 degrees Celsius, and a receiver that receives the water of the first temperature and that is configured to store the water of the first temperature or the extracted coffee liquid.

A method for making cold brew coffee and a system for brewing cold brew coffee is described. A cold brew coffee device may include a water reservoir containing water, a plurality of tubes for transporting water in the water reservoir to a different location, a drip mechanism for receiving water from the water reservoir, a coffee grounds container for receiving water from the drip mechanism, a pump for pumping water from the water reservoir to the drip mechanism, a container for collecting coffee-infused water from the coffee grounds container, a user interface for displaying information and providing alerts, a controller for controlling the pump and user interface, and a battery for providing power to the controller, the pump, and the user interface.

A beverage brewer spray apparatus includes a lid, one or more dispersal members, and a skirt. The lid has obverse and converse surfaces, with at least one recessed region in the obverse surface. The dispersal members extend from the converse surface at open proximal ends. The skirt has a proximal end fixed to and extending outward from the converse surface of the lid. Each dispersal member has a sidewall and a distal end defining an interior of the dispersal member. The sidewall has apertures arranged in a distal section of the sidewall. The lid has through-holes formed between the obverse and converse surfaces, and the dispersal members are fixed to the converse surface such that the through-holes provide fluid communication from the obverse surface of the lid to the apertures through the interiors of the dispersal members. The apertures are configured to direct liquid outward from the dispersal members.

A kitchen appliance for preparing beverage comprises a housing, a basket holder in cooperative engagement with the housing, a filter basket selectively insertable into the basket holder when the basket holder is in an open position, and a ground coffee hopper for holding ground coffee. The hopper is positioned to dispense a desired amount of ground coffee into the filter basket when (i) the hopper is selectively mounted to the housing, (ii) the filter basket is inserted into the basket holder, and (iii) the basket holder is in its closed position. The bottom portion comprises a selectively rotatable doser defining a plurality of dosing cavities. Each dosing cavity is adapted to contain a same, predetermined amount of ground coffee and adapted to dispense the contained ground coffee through a dispensing hole defined in the bottom portion as each dosing cavity is rotated into a position above the dispensing hole.

A machine which contains a housing (14) having a placement surface for the beverage container (13), wherein a removable brewing container (8) having a drain stub (19) and having a drain valve (10) that can be electrically or electromagnetically opened and closed is arranged in the housing (14). The actual brewing process is automatically controlled by a control unit (11). The water is pumped by a vibrating armature pump (16) through a heating system (15) and through a water outlet in the cover (4) having an integrated temperature sensor (24) through the cover (5) into the brewing container (8). A pressure sensor (12) ensures that the water is not heated above the pressure-dependent current boiling point. The control unit (11) can be programmed by means of a control panel (7) on the housing, for at least the brewing temperature, the brewing duration, and the start of a brewing cycle. Furthermore, a radio interface and an associated antenna (9) are present, for the communication of the control unit (11) with a smartphone by means of an established communication standard such as WIFI or Bluetooth, or with a computer or laptop via the internet, such that the machine can be remotely operated.
