Claim 6:
7. A method for obtaining a capsule for preparation of a coffee-based beverage according to claim 1, comprising the steps of:
a) providing the capsule body that defines the chamber designed to receive the precursor of the beverage and having the outlet wall for outflow of the beverage from the capsule;
b) introducing into the chamber the beverage precursor in powder form, which includes soluble coffee powder and roast and ground coffee powder; and
c) providing the capsule body with the inlet wall for introduction of water into the capsule,
wherein step b) comprises the operations of:
b1) introducing into the chamber an amount of roast and ground coffee powder having a grain size expressed in x50 comprised between 350 and 800 μm, to form a lower layer;
b2) densifying the roast and ground coffee powder of the lower layer via mechanical pressing; and
b3) introducing into the chamber an amount of soluble coffee powder having a grain size expressed in x50 comprised between 1000 and 5000 μm, to form an upper layer without mechanical pressing,
wherein the roast and ground coffee powder of the lower layer forms at least 51 wt % of the precursor in powder form, and the soluble coffee powder of the upper layer forms a complement to 100 wt % of the precursor in powder form.
