A coffee or tea brewing apparatus comprising a hollow cylinder with top and bottom openings, a permeable filter, a filter retaining ring which attaches to the bottom end of the hollow cylinder and encloses the bottom opening of the hollow cylinder with the permeable filter, a support ring to support the hollow cylinder above an open vessel, and a flexible lid. Coffee grounds or tea leaves are mixed with water inside the hollow cylinder which will then drain through the removable filter effectively separating any liquids into an open vessel while retaining undissolved solids within the hollow cylinder. The flexible lid may be used to enclose the top of the hollow cylinder and pressed on to produce a positive air pressure within the filter assembly to force the liquid through the permeable filter when a faster flow rate is desired.

Apparatus for measuring the operating parameters of espresso coffee machines, comprising: a filter-holder body configured to be associated with a water dispensing nozzle of an espresso coffee machine; said body internally defining a chamber for the passage of the water dispensed by said nozzle; a filling element arranged in said chamber and having a cavity for the passage of the water dispensed by the nozzle towards an outlet duct; a water outlet terminal element associated with said filter-holder body downstream of said chamber and defining said water outlet duct; and reading means for the water pressure and temperature values passing from the chamber to the outlet duct; said reading means comprise at least one pressure reading device operatively engaged with said water outlet terminal element and at least one temperature reading device operatively engaged at said cavity obtained in the filling element.

A machine for preparing aromatic beverages by extraction, such as espresso coffee and similar beverages. The machine comprises at least one optimized beverage discharge disposition, in particular presenting a first and second flow sections separated by a throttling section that configures a double deflection of the prevailing flow direction, so that it provides a streamlining of the discharge flow.
