A method of brewing a flash brewed coffee concentrate includes flash brewing ground coffee to brew a hot coffee extract and mixing the hot coffee extract with a frozen concentrated coffee extract to chill the hot coffee extract to a temperature less than 130° F. while increasing the concentration of the hot coffee extract to form the flash brewed coffee concentrate.

A process for producing a liquid coffee concentrate that has a reduced acrylamide content. The process involves contacting a low aromatic aqueous coffee extract with a selectively-permeable membrane to reduce the acrylamide content of the extract, prior to combining the treated extract with a high aromatic aqueous coffee extract. In particular, the process comprises the steps of: a) providing a low aromatic aqueous coffee extract having a first acrylamide content; b) providing a high aromatic aqueous coffee extract; c) contacting the low aromatic aqueous coffee extract with a selectively-permeable membrane to provide a low aromatic aqueous coffee extract having a second acrylamide content; and d) combining the low aromatic aqueous coffee extract having a second acrylamide content and the high aromatic aqueous coffee extract to provide a liquid coffee concentrate, wherein the second acrylamide content is lower than the first acrylamide content.

Disclosed is a portable cold brewer with drinkware for brewing a brewed effluent from a filter bag containing an organic material. The portable cold brewer with drinkware comprises a brewing section, a mid-section, and a lid. The brewing section includes a housing having a brewing section top and a brewing cavity within the housing. The brewing cavity includes an organic material measure marking and a brew line marking. The organic material measure marking is configured to measure an amount of organic material that will fill the filter bag, the brewing cavity is configured to receive the filter bag containing the organic material that was measured by the organic material measure marking, and the brew line marking is configured to measure an amount of water to fill the brewing cavity when the filter bag is inserted into the brewing cavity. The mid-section has a dilution section and a dilution line marking, where the mid-section is configured to cover the brewing section top, and the lid is configured to cover the dilution section.

A brewer system includes a reservoir, a steep chamber movable relative to the reservoir and positioned over a mouth of the reservoir, and a filter tape positioned between the chamber and the reservoir. Brewing substance and water are added to the chamber to form a brewed beverage that passes through the filter tape and into the reservoir through the mouth.

A method of recognizing a type of coffee from reference types of coffee, wherein each of the reference types of coffee is associated with a respective reference signal and wherein each type of coffee is associated to a characteristic combination of volatile organic compounds released from the type of coffee, may include: sensing, by one or more sensors, presence and concentration of one or more volatile organic compounds in a mixture of volatile organic compounds released from the type of coffee; generating a signal representative of the type of coffee according to the sensed one or more volatile organic compounds and the respective concentrations of the sensed one or more volatile organic compounds; comparing the generated signal with the reference signal associated with each of the reference types of coffee; and generating a recognition signal in response to the comparing of the generated signal with the reference signals.

A carafe for holding a liquid includes a body having a cavity that is operable to hold a liquid, and a vent that allows fluid, such as air, to flow out of the cavity to the ambient environment, and from the ambient environment into the cavity, while liquid flows into and out of the cavity. The cavity has a mouth through which liquid flows when the liquid flows into the cavity and out of the cavity. The vent includes a passage that extends into the cavity of the body and has a first opening at a first end of the passage, a second opening at a second end of the passage. The passage's first opening is located in the cavity, the passage's second opening is located at the cavity's mouth. The passage is configured such that only the first opening and the second opening allow fluid access into the passage, and air inside of the cavity flows out of the cavity through the second opening when liquid flows into the cavity through the mouth.
