Many embodiments described herein prevent an aged spirit from degrading due to the oxygen trapped in the headspace without the use of a pump. The aged spirit preservation system may have a cork with an open top, an open bottom, and a channel extending from the open top to the open bottom. The cork may be sized couple to an internal portion of a bottle. The system may even include a sealing device coupled to an outer portion of the cork between the open top and the open bottom. Additionally, the system may include a replaceable cartridge containing an adsorbent media, iron, a salt, and a color-changing indicator. Oxygen from the bottle may be allowed to enter the cartridge and react with the iron via a non-reversible reaction, thereby preventing the degradation of the spirit.

Aged spirit preservation systems and devices

A filter medium for use in filtering a mobile fluid made from at least a bicomponent fiber. Other fibers, particles, or other materials can also be entrained in the filter medium. The filter medium has a substantial thickness compared to filters of the prior art. The fiber length and diameter dimensions are selected to obtain desired filter characteristics including thickness, basis weight, pore size, filtration efficiency, pressure drop, burst strength, and manufacturing efficiency. Further, a multilayer filter medium can be provided with ease. Each layer can have a different composition, pore size, basis weight, and so forth, thus providing the ability to build multiple functionality into the filter media of the invention.
