1. An insert for a mechanical clamping cap of a screw and crown type, for closure of bottles, said insert comprising a sealing element capable of being compressed in one part between a body of a bottle cap and a portion of said bottle when said cap is closed over said bottle, and comprisinga permeating element, said permeating element being impermeable to liquids and having a permeability to oxygen measured at 20° C. of between 10−6 and 10−10 Ncm3*cm/cm2*cmHg*s, wherein said permeating element is of a compact type,said permeating element being positioned and configured to close a passage made in said bottle cap between an inside and outside of the bottle, and having a thickness and surface such as to control the flow of oxygen between the inside and outside of the bottle, with the cap fitted, between 0.1 and 5 milligrams per month; said permeating element being positioned such that passage of air between the outside and inside of a bottle over which said cap is closed, occurs only through the permeating element, so as to enable a flow of oxygen into and out of said bottle sufficient for the process of aging wine contained in the bottle;wherein said insert is configured to be fixed to a portion of a surface of said body of said bottle cap. 2. The insert according to claim 1, wherein said permeating element has a permeability to oxygen measured at 20° C. of between 10−7 and 10−10 (Ncm3*cm/cm2*cmHg*s). 3. The insert according to claim 2, wherein said sealing element comprises a material that is substantially impermeable to oxygen and said permeating element comprises a membrane extending to close at least a portion of a passage crossing said sealing element and capable of placing the interior of said bottle in communication with an environment outside the bottle. 4. The insert according to claim 3, wherein on said sealing element there is at least one communication channel between the environment outside the bottle and said passage from the side of said membrane that faces an environment inside the bottle. 5. The insert according to claim 4, wherein said at least one communication channel comprises at least one groove made on a surface of said sealing element designed to face said body. 6. The insert according to claim 3, wherein said passage comprises a first and second edge opposite each other, said first edge being designed to be closed by said surface of said body of the cap and said second edge being closed at least in part by said membrane. 7. The insert according to claim 6, wherein said membrane is integrally fixed to said sealing element. 8. The insert according to claim 6, including a closing element closing off said second edge of said passage, there being a through-hole, in said closing element, closed by said membrane. 9. The insert according to claim 8, wherein said closing element has at one end a recess, inside which said membrane is housed. 10. The insert according to claim 8, wherein said closing element includes a perimetric projection for fixing to said sealing element. 11. The insert according to claim 8, wherein said closing element is made in one piece with said sealing element by moulding. 12. The insert according to claim 8, wherein said closing element is obtained by co-moulding with said sealing element or by over-moulding said sealing element. 13. The insert according to claim 8, wherein said membrane is fixed to said closing element by means selected from the group consisting of over-moulding, ultrasound welding, and gluing. 14. The insert according to claim 1, wherein said sealing element is part of said permeating element and forms a single and homogeneous body therewith. 15. The insert according to claim 14, wherein said sealing element is connected to a film that is impermeable to oxygen over the entire surface except for a region with a pre-defined area, through which the controlled passage of oxygen occurs. 16. The insert according to claim 15, wherein said region has a reduced thickness. 17. The insert according to claim 14, wherein said sealing element has a substantially uniform thickness and is made of a material selected from the group consisting of rubbers, block styrene-based copolymers and cellulose derivatives. 18.
