Definitions

  • the invention is applicable to the beverage brewing industry.
  • the present invention relates to beverage brewing and in particular to a brewing device for hot or cold brewing of beverages.
  • beverage infusions such as coffee, tea, yerba mate, and herbal infusions (tisane)
  • hot water is typically used.
  • cold brewing that is, infusion of the beverage material in cold or room-temperature water rather than in hot water
  • bitterness and acidity can be avoided when brewing certain teas by steeping in unheated water rather than hot water.
  • Such cold brewing is accomplished by submerging a portion of brewing material in unheated water for a period of time to allow the brewing material to infuse the water. While the steeping process may provide a desired result, the time required for cold brewing is longer than that required for brewing in hot water.
  • Adding an agitation or rotation feature to the cold brewer has been shown to reduce the cold-brewing time.
  • Another manner of speeding the process would be to increase the flow of brewing liquid through the brewing material.
  • Some conventional devices use a gravity feed to draw water through the brewing material using a percolator-type action, which speeds brewing time somewhat.
  • these systems tend to have a motorized system outside the brewing container to provide the gravity action, resulting in a brewer having a large footprint that takes up considerable counter space.
  • a reliable, rapid cold-brewing system that uses a fluid feed to increase the fluid flow would provide an overall improved brewing experience it would also be advantageous if such a system could be configured as a compact unit, preferably a unit that could be portable. Flexibility would be provided if the brewing system can also be used to hot-brew a beverage, or if it can be used to warm a beverage that had been cold- brewed by the system, in order to serve a warm or hot beverage that has the cold-brew taste. Such a system that uses the beverage serving vessel as the source of the fluid used to brew the beverage would make the unit more compact and simple to use and clean.
  • a system having a simple feature allowing the brew line to be cleaned quickly between brews would reduce the potential for pathogen buildup, would make it easier to brew beverages of different types with the same system without cross-flavoring the beverages, and would keep the brewed beverages fresher tasting.
