Wine Preservation 101: How to Keep an Open Bottle Fresh
Opened wine's enemy is oxygen — it oxidises fresh fruit into tired, flat flavours within a day or two. Preservation is about removing or shielding from oxygen.
Here's the honest ranking of open-bottle technology, from the $5 hack to the serious tools.

The preservation toolbox
The simplest effective move is recorking and refrigerating — cool slows oxidation dramatically, and within 2–3 days most wines stay fine. Neutral gas (argon) sprays and 'wine savers' displace oxygen for wine that must last a week. Vacuum pumps help modestly; storage balls and nitrogen taps are the serious end.
- Recork + fridge — 2–3 days, free and effective
- Argon gas spray — 4–7 days, easy
- Vacuum pump — modest gain
- Professional taps (Coravin) — months, at a price
What not to do
Don't pour wine back into its original half-empty bottle after days, don't leave a nearly-empty bottle of fine red at room temperature, and accept that mousy, oxidised wine is best in the cooking pot.
