A method and apparatus provides a coffee beverage having a reduced terpene content, where a brew chamber has a brew area A is provided and a volume of water is provided to flow through the coffee grounds in the brew chamber and out of the brew chamber to provide a coffee beverage, and where the flow rate of water provided through coffee grounds in the brew chamber is F and the ratio of F/A is about 0.15 cm/s or less.

The present invention relates to a method for processing coffee cherries using deep seawater and microorganisms. The method processes coffee cherries by using microorganisms and deep seawater, such that the amount of defective coffee cherries are reduced, a processing time of green beans is shortened, and a content of trigonelline which is a precursor of an aroma component of coffee is increased.

The present invention relates to a device 1 for refining the taste of beverages 7 with an irradiation chamber 2, wherein the irradiation chamber 2 is configured to receive a beverage vessel 6, in particular a beverage glass or a beverage bottle, and at least one radiation source 9, the at least one radiation source 9 being arranged within the irradiation chamber 2 and is configured to emit a first radiation 10 with a wavelength out of a wavelength range between 270 nm and 450 nm, wherein the beverage vessel 6 is providable in the irradiation chamber 2 to be irradiated with the first radiation 10.

The present technology provides a method for preparing an acid-reducing filter that includes depositing a mineral blend layer to a filter substrate, where the mineral blend layer comprises calcium carbonate and magnesium carbonate at a weight ratio of about 1:10 to about 10:1, the mineral blend is free of soluble halide or hydroxide salts of alkali or alkaline earth metals, and the mineral blend layer is insoluble in water.

Disclosed herein is a method for processing green coffee beans, including: (1) loading unroasted green coffee beans on a mesh-like plate, placing in a container the mesh-like plate having the green coffee beans loaded thereon, introducing water into the bottom of the container so as to be spaced apart from the lower surface of the mesh-like plate, and closing the lid of the container to seal the container; (2) placing the sealed container in a heating cabinet, and then steaming the green coffee beans at low temperature for 10 to 12 days while maintaining the internal temperature of the heating cabinet at 70 to 80 C.; and (3) opening the lid of the container, and then drying the steamed green coffee beans for 4 to 6 days while maintaining the internal temperature of the heating cabinet at 38 to 43 C.

The present invention relates to a method for preparing aroma-infused coffee beans. Further aspects of the invention are roasted aromatic alcoholic beverage-infused coffee beans having low levels of ethyl carbamate, as well as the use of reduced-alcohol aromatic alcoholic beverage to infuse coffee beans.

A coffee degassing device is disclosed and method. The coffee degassing device comprises a coffee bin and a hollow tree within the bin. The hollow tree has an opening in communication with the interior of the coffee bin. The tree provides an exit path for carbon dioxide off-gassing from the coffee. The device may have a diffusion gas supply conduit. The diffusion gas supply conduit is in communication with the hollow tree and is configured to supply nitrogen, or another diffusion gas, to the degassing tree for accelerating the degassing of coffee.

A bean roasting system includes a roasting chamber, a blower, a variable diverter and a controller. The roasting chamber, the blower and the variable diverter each is disposed at least partially within a recirculating gas flow path. The blower is configured to provide a flow stream of gas through the recirculating gas flow path. The variable diverter is configured to split the gas flow path into at least two flow paths including a treated flow path and a bypass flow path. The treated flow path includes a series arrangement of a gas heater and a catalytic converter. The variable diverter is configured to control a percentage of a flow stream of gas that is diverted into the bypass flow path. The controller is configured to activate different predetermined operating modes for the bean roasting system by controlling a state of the variable diverter and a state of the heater.
