Wine Preservation Systems Compared
Opened wine oxidises. Air is the enemy — once a bottle is open and partially drunk, avoiding oxidation means either removing the air, blanketing the surface with gas, or chilling to slow the reaction.
Preservation products range in ambition from the humble stopper to argon-based systems that can safely 'sip' from an unopened bottle for months. Knowing their limits saves money and frustration.

The cheap fixes that actually help
Closing the bottle with its own cork and moving it to the fridge adds several days of life to whites and young reds — cold slows oxidation more than people credit.
A vacuum pump costs little and helps; gas-in-a-can systems (Private Preserve) do the same job more reliably by blanketing the headspace in inert gas.
The Coravin revolution
Argon injection systems like Coravin pierce the cork and withdraw wine while replacing the volume with inert argon, letting you taste a bottle without ageing the rest. Expensive, legitimately brilliant, and the ultimate dinner-party flex.
- Vacuum pumps: cheap, mild benefit.
- Inert-gas sprays: better, a few dollars per can.
- Coravin-style: luxury, but lets you 'sip' and save the rest for months.
The honest verdict
For most people the best preservation is simply finishing the bottle sooner — or choosing a smaller format. Between a fridge and a vacuum pump, 72-hour freshness is realistic. Only Coravin unlocks week-plus preservation of fine wines.
