The capsule of claim 1, wherein the area of the opening region is from 100 mm2 to 250 mm2. 5. The capsule of claim 1, wherein the lines of weakness partially surround the opening region so that the opening region of the lid forms a flap once the lid is opened. 6. The capsule of claim 1, wherein some of the lines of weakness are arranged along a first curve and others of the lines of weakness are arranged to extend from ends of the first curve along a second curve, so that the resulting opening is approximately elliptical in shape with a short axis aligned along the radial direction of the capsule and a perpendicular long axis. 7. The capsule of claim 6, wherein the short axis has a length of from about 8 mm to about 18 mm, and the long axis has a length of from about 25 mm to about 35 mm. 8. The capsule of claim 1, wherein the lines of weakness are perforations. 9. The capsule of claim 1, wherein the lid is an aluminium foil/polyethylene laminate lid and the cut:tie ratio of the perforations is from about 1:1 to about 1:3. 10. The capsule of claim 1, wherein the lines of weakness are equally divided into a first group defining the opening region and a second group defining a second opening region; and wherein the opening region and the second opening region are on opposite sides of the capsule. 11. The capsule of claim 1, wherein the cavity is filled with from 25 to 60% by volume of tea material. 12. A method of preparing a tea-based beverage in a brewing device using a capsule according to claim 1, the device comprising: an infusion chamber with a bottom rim which defines an opening;a capsule holder for receiving a capsule, the capsule holder comprising a sidewall defining an internal volume and having an upper rim, a filter coupled to the sidewall below the upper rim, the filter spanning across the internal volume, and an openable and closable passage extending through the sidewall at a location below the filter; andmeans for opening the opening region of the capsule lid;the method comprising steps of:a) inserting the capsule into the capsule holder;b) connecting the upper rim of the capsule holder to the bottom rim of the infusion chamber;c) introducing liquid into the capsule and releasing the tea material from the capsule so that the liquid and tea material mix and flow into the infusion chamber so as to brew the beverage; andd) after brewing has taken place, opening the passage in the capsule holder to allow the beverage to flow from the infusion chamber through the filter and out through the passage;wherein the opening region of the capsule lid is opened by the opening means during step b). 13. A brewing device containing a capsule according to claim 1, the device comprising: an infusion chamber with a bottom rim which defines an opening;a capsule holder for receiving a capsule, the capsule holder comprising a sidewall defining an internal volume and having an upper rim, a filter coupled to the sidewall below the upper rim, the filter spanning across the internal volume, and an openable and closable passage extending through the sidewall at a location below the filter;means for moving the capsule holder and/or the infusion chamber so that the upper rim of the capsule holder is connected to the bottom rim of the infusion chamber;means for opening the opening region of the capsule lid;means for introducing liquid into the capsule so that the liquid and tea material can mix and flow into the infusion chamber so as to brew a beverage; anda valve for opening the passage in the capsule holder to allow the beverage to flow from the infusion chamber through the filter and out through the passage. 14. A multipack containing a plurality of capsules according to claim 1. 15. A method of preparing a tea-based beverage in a brewing device using a capsule, the capsule being for use in the brewing device, the capsule comprising: a body part, which defines a cavity;a lid which is attached to the body part and which closes the cavity, the lid having lines of weakness which define an opening region having an area of from 75 mm2 to 300 mm2, the lines of weakness interspaced by a plurality of distances; andtea material enclosed within the cavity, wherein at least 75% by weight of the tea material particles have a size of from 2 to 10 mm;the brewing device comprising:an infusion chamber with a bottom rim which defines an opening;a capsule holder for receiving a capsule, the capsule holder comprising a sidewall defining an internal volume and having an upper rim, a filter coupled to the sidewall below the upper rim, the filter spanning across the internal volume, and an openable and closable passage extending through the sidewall at a location below the filter; andmeans for opening the opening region of the lid;the method comprising steps of:e) inserting the capsule into the capsule holder;f) connecting the upper rim of the capsule holder to the bottom rim of the infusion chamber;g) introducing liquid into the capsule and releasing the tea material from the capsule so that the liquid and tea material mix and flow into the infusion chamber so as to brew the beverage; andh) after brewing has taken place, opening the passage in the capsule holder to allow the beverage to flow from the infusion chamber through the filter and out through the passage;wherein the opening region of the lid is opened by the opening means during step b). 16. The method of claim 15, wherein the flap thus formed opens inwardly into the cavity of the capsule. 17. The method of claim 15, wherein the capsule has a top face positioned proximate to the upper rim and a bottom face opposite the top face; and wherein the top faces comprises the lid having lines of weakness. 18.
