Estimating the term…
The present invention relates to a filter element for the extraction or brewing of beverages. In particular, the filter element facilitates brewing through increased permeability of fluid from a brewed beverage from brewable particles, such fluid including liquid and gas, and the easing of gas build up in a brewing device herein by the removal of gases emitted from a beverage medium housed within a beverage cartridge during brewing. The filter element may be used within a rigid, semi-rigid or soft pod that is insertable within a beverage brewer. The invention particularly concerns the brewing of coffee and coffee products in a coffee brewing machine configured to receive pods holding coffee particles that are injected with water and caused to brew coffee therefrom.

The beverage cartridge of any of the preceding claims wherein said number of microperforations within said filter element ranges from between about 2 to about 1000 microperforations.
The beverage cartridge of any of the preceding claims wherein said filter element comprises open areas positioned on said first surface and said second surface of said filter element that are greater than about 2% of the total surface area of said filter element.
The beverage cartridge of any of the preceding claims wherein each said microperforation comprises an average diameter ranging from between about 0.1 mm to about 0.8 mm.
The beverage cartridge of any of the preceding claims wherein said beverage medium is freshly ground coffee particles having a maximum gas content.
The beverage cartridge of any of the preceding claims wherein said freshly ground coffee is dark roasted.
