I like the idea of vacuum sealing or removing as much air as possible from the casings. I think oxidation from air exposure contributes to the degradation of the casing even when kept cold and salted. I have seen some tubed casing packed submerged in a saturated brine solution, which seems like a good idea. Keeping unused casing clean before repacking should help with extending their shelf life.

Thanks Joe & Jonathan, I’ll try both ideas on the next round coming up this weekend.
