The present disclosure relates generally to preparing ground coffee beans for use in producing café style beverages.
As specialty coffee beverages such as espressos, cappuccinos and lattés increase in popularity, the sophistication of coffee preparation has also advanced. To those skilled in the art of coffee preparation, once novel processes and procedures are now becoming standard practice.
In the preparation of espresso beverages, coffee is usually ground directly into a portafilter, tamped down using a plunger like device, and then affixed to an espresso machine that pumps hot water through the compacted coffee grounds at a predetermined pressure. Instead of grinding directly into a portafilter, sometimes an intermediary vessel such as a cup is used. Using this method allows for the grounds to be stirred, weighed, etc., before being transferred into a portafilter. The stirring process in particular is relevant to this invention.
As coffee is ground and allowed to settle directly into a vessel, denser particles of ground coffee tend to accumulate at the bottom of the volume and the lighter particles at the top. In addition, particles of various sizes of coffee grounds are unevenly distributed within the volume. Brewing a dose of ground coffee, with an un-homogenized particle distribution for espresso, yields undesired results. Channeling—where hot water preferentially flows through a path of low resistance and sprays out of the portafilter without properly brewing the coffee, spritzing—where jets of inadequately brewed coffee sprays from the bottom of the portafilter basket, or sub-optimal tasting coffee can occur.
Those skilled in the art of specialty coffee preparation often choose to redistribute or mix the grounds to homogenize the particle distribution. This process is quickly being adopted as an accepted process for producing higher quality espresso. This invention aims to streamline and improve the intermediary process of redistribution in a separate vessel.
Embodiments will now be described with reference to the following drawings, which are provided by way of example, and not limitation.
In general, the present disclosure relates to a vessel, which allows for the redistribution or homogenization of particles of ground coffee, and filling of a secondary vessel such as a portafilter. Ground coffee with particles not redistributed or homogenized is referred to as “un-homogenized.”
