A cap 1 adapted to cover an end of a cask for maturation of a spirit, comprises a body 10 having an outer plate 11 and a flange 13 extending from the outer plate, and an inner plate 30 spaced from the outer plate. The inner plate lies between the outer plate and the end of the cask when the cap is in place on the end of the cask. A layered or ridged spacer 40, 41 can separate the plates, and can permit fluid transfer in the space between the plates. The inner plate can be resistant to vapour transfer, and can be pressed against the outer surface of the end of the cask when the cap is in place on the end of the cask, and leaves an annular area of the end of the cask uncovered. A collar 20 supports the flange 13, and at each side on the circumference of the outer plate, the material of the body is scored or creased or otherwise treated or constructed to form a hinge between the outer plate and a flange segment 14, allowing the flange segment to bend. The collar can reinforce the flange, and incorporates a sequential arrangement of wall segments 21 interconnected by hinges in the form of creases 22. |
