1. A method for preparing a beverage, the method comprising:
providing a capsule comprising containment walls forming an interior cavity containing a beverage precursor for mixing with a liquid in the interior cavity, wherein the beverage precursor comprises a combination of non-compacted beverage extractable powder and pellets of compacted beverage extractable powder, and a largest dimension of each pellet is at least 3.5 millimeters, wherein the containment walls comprise a liquid inlet wall and a beverage outlet wall, and all of the pellets of compacted beverage extractable powder are positioned closer to the liquid inlet wall than to the beverage outlet wall;
feeding the liquid under pressure in the interior cavity containing the beverage precursor to form the beverage; and
extracting the beverage out of the capsule, wherein a portion of the beverage is obtained from the pellets of compacted beverage extractable powder,
the beverage precursor is essentially roast-and-ground coffee, the pellets are also essentially roast-and-ground coffee, and a percentage of the pellets to a total weight of the roast- and-ground coffee in the cavity is between 20 and 80 wt. %,
the pellets are compacted from loose roast-and-ground coffee powder with an average diameter D4,3 comprised between 600 μm and 1000 μm, and the non-compacted beverage powder is roast-and-ground coffee with an average diameter D4,3 between 160 μm and 1000 μm; and
an envelope density of the pellets of compacted beverage extractable powder is between 500 g/1 and 800 g/l.
