To a certain extent, the more expensive the wine and the better the vintage, the more likely it is to last for longer than a cheap and cheerful bottle of plonk. Quality red wines with high levels of tannin are more resilient and reliable. Sadly though, without a wine preservation system, even that bottle you dusted off from the cellar to celebrate your engagement will degrade so if you do love wine, then it makes complete sense to invest in a wine sealing system of some description.\r
