1. A system for preparing a predetermined quantity of beverage suitable for consumption using an extractable product, comprising: a first exchangeable capsule, being a closed capsule, having a bottom and having a first length;a second exchangeable capsule, being an open capsule, having a bottom comprising an entrance filter and a second length, said first length being larger than the second length;a first apparatus comprising a receptacle with a support surface for holding the first capsule, the receptacle of the first apparatus having a shape complementary to a shape of the first capsule the first apparatus having bottom piercing means intended for piercing the bottom of the first capsule, and having a fluid dispensing device for supplying an amount of a fluid under pressure to the first capsule, the bottom piercing means of the first apparatus being displaceable together with the receptacle of the first apparatus from a retracted position to an extended position, said bottom piercing means of the first apparatus being arranged for in the extended position piercing the bottom of the first capsule when the first capsule is placed in the receptacle of the first apparatus, the receptacle of the first apparatus being further configured to hold a second capsule, the shape of the receptacle of the first apparatus being partly complementary to a shape of the second capsule, wherein the bottom piercing means of the first apparatus are arranged for in the extended position being positioned at a distance from the bottom of the second capsule when the second capsule is placed in the receptacle of the first apparatus, so that the entrance filter of the second capsule, when being used in the first apparatus, is not pierced by the bottom piercing means of the first apparatus and the bottom of the second capsule stays intact; anda second apparatus comprising a receptacle with a support surface for holding the second capsule, the receptacle of the second apparatus having a shape partly complementary to the shape of the second capsule, the second apparatus comprising lengthened bottom piercing means and a fluid dispensing device for supplying an amount of a fluid under pressure to the second capsule, the lengthened bottom piercing means of the second apparatus being longer than the bottom piercing means of the first apparatus, the lengthened bottom piercing means of the second apparatus being displaceable together with the receptacle of the second apparatus from a refracted position to an extended position, said lengthened bottom piercing means of the second apparatus being arranged for in the extended position piercing the entrance filter of the second capsule for creating at least one opening in the entrance filter of the second capsule when the second capsule is placed in the receptacle of the second apparatus, the receptacle of the second apparatus being further configured to hold the first capsule, the shape of the receptacle of the second apparatus being complementary to the shape of the first capsule;wherein upon retraction of the receptacle of the second apparatus the second capsule is moved in a refraction direction of the receptacle. 2. The system of claim 1, wherein the second capsule comprises a circumferential wall, wherein the bottom is provided at a first end of the circumferential wall, and a lid at a second end of the circumferential wall opposite the bottom, wherein the wall, bottom and lid enclose an inner space comprising the extractable product, and wherein the lid comprises an exit area and the second apparatus comprises an outlet which, in use, is in fluid communication with the exit area for draining the prepared beverage from the second capsule and supplying the beverage to a container. 3. The system of claim 2, wherein an initial connection force between the lengthened bottom piercing means of the second apparatus and the entrance filter of the second capsule is larger than a sticking force between the lid of the second capsule and at least part of the support surface of the receptacle of the second apparatus. 4. The system of claim 2, wherein the lengthened bottom piercing means of the second apparatus comprises at least one piercing element having a length that is chosen such that a piercing end of the piercing element, in use, extends at least partially through the entrance filter of the second capsule. 5. The system of claim 4, wherein the length of the at least one piercing element is chosen such that it, in use, pierces the second capsule over at least 2.7% of its length along a longitudinal central axis of the second capsule from the entrance filter towards the lid of the second capsule. 6. The system of claim 4, wherein the length of the at least one piercing element is adapted to, in use, pierce the first capsule over at least 21.7% of its length along a longitudinal central axis of the first capsule from the bottom towards a lid of the first capsule. 7. The system of claim 6, wherein the first length of the first, capsule is 30 mm along a longitudinal central axis of the first capsule. 8. The system of claim 1, wherein a thickness of the entrance filter of the second capsule is approximately 0.65 mm to approximately 0.75 mm. 9. The system of claim 1, wherein the second length of the second capsule is 23.5 mm 23.9 mm along a longitudinal central axis of the second capsule. 10. The system of claim 1, wherein the entrance filter of the second capsule is selected from the group consisting of a flexible porous sheet, a flexible foil provided with a plurality of entrance openings, a polymeric film provided with a plurality of entrance openings, and a plurality of entrance openings provided in the bottom of the second capsule. 11. The system of claim 1, wherein the bottoms of both the first and second capsules are substantially flat, wherein sidewalls of the first and second capsules generally taper from the bottom to a top, and wherein the tops of the first and second capsules have larger surface areas than the bottoms of the first and second capsules.
