Claim 4:
5. A capsule for extraction of a coffee-based beverage, having a capsule body made of a water-impervious material, the capsule body defining a chamber, within which is a precursor of the beverage, that comprises soluble coffee and roast and ground coffee, the capsule body being configured so as to have an inlet wall, for introduction of pressurized water into the capsule body, and an outlet wall, for outflow of the beverage from the capsule body,
wherein at least 51 wt % of the precursor is roast and ground coffee having a grain size expressed in x50 comprised between 350 and 800 μm,
wherein a complement to 100 wt % of the precursor is soluble coffee having a grain size expressed in x50 comprised between 1000 and 5000 μm,
wherein the roast and ground coffee is laid out to form a first layer in a lower part of the capsule body, the lower part being in a position corresponding to the outlet wall, and the soluble coffee is laid out to form a second layer in an upper part of the capsule body, the upper part being in a position corresponding to the inlet wall and/or above the first layer,
wherein the first layer of roast and ground coffee is densified, or pressed, within the capsule body, and the second layer of soluble coffee is within the capsule body substantially undensified or unpressed,
wherein the total weight of the precursor is comprised between 5 g and 12 g,
wherein:
the first layer of roast and ground coffee comprises between 5 g and 8.5 g of roast and ground coffee; and
the second layer of soluble coffee comprises between 1 g and 3.5 g of soluble coffee.
