A coffee machine is described. The coffee machine has a removable coffee vessel for fitting to a docking area. A closing piston is driven laterally relative to the coffee vessel into a side opening of the coffee vessel. The closing piston has a water delivery channel leading to its end face.

A coffee grinding apparatus includes a removable holder assembly having first and second arms that are spaced-apart from one another to define an open receiving area therebetween. The arms each include upper and lower tabs that extend inwardly into the open receiving area first and second distances, respectively. The first and second distances of the upper and lower tabs are configured to retain and support portafilter assemblies of various sizes for filling with coffee grounds using the coffee grinder apparatus. Another holder assembly for use with the coffee grinding apparatus may include opposed abutment surfaces for engaging inner and outer surfaces of a cup portion of various sized portafilter assemblies. Each disclosed holder assembly is configured to attach to a pedestal portion of the coffee grinding apparatus in use, and can be stored in a support base of the coffee grinding apparatus when not in use.

An espresso machine has a built-in coffee grinder. A coffee grinding apparatus cooperates with a removable portafilter having a handle, the apparatus including: a cradle for supporting the portafilter; an actuator adjacent to the cradle for co-operating with the portafilter; a downward facing ledge engages a front tab of the portafilter for resisting imbalance of the portafilter when supported by the cradle. Wherein, when the portafilter is supported by the cradle and advanced forward, the front tab of the portafilter further contacts the actuator to operate an electrical switch, thereby causing a signal to be sent to a microprocessor for delivering coffee grinds to the portafilter.

A coffee dispenser comprises an inlet for receiving ground coffee, a ground coffee holder that receives ground coffee from the inlet, and a porta filter carriage for receiving a porta filter. The porta filter carriage is movable relative to the ground coffee holder between a closed position and a dispensing position. When a porta filter is received in the porta filter carriage, movement of the porta filter carriage from the closed position to the dispensing position causes coffee to be dispensed into the filter basket. Movement of the porta filter carriage from the dispensing position to the closed position causes a scraping action to occur across the coffee disposed in the filter basket, thereby removing excess coffee from the filter basket.

Provided is an apparatus for preparing a coffee beverage portion from a volume of water and a mass of coffee beans. The apparatus includes a brewing chamber for containing the ground coffee. The chamber admits water via an inlet. The water contacts the ground coffee contained within the chamber, and exits the chamber via an outlet. A ground coffee supplier dispenses coffee beans to the chamber, and a water supply supplies water to the chamber. A controller controls the ground coffee supplier and the water supply such that the coffee beverage portion is brewed in a plurality of brewing steps. Each brewing step includes passing a fraction of the water volume through the chamber so as to contact a further fraction of the coffee beans mass during a time period equal to the desired brewing time. Further provided is a method of preparing a coffee beverage portion.
