Wine preservation comparison
Coravin vs Vacu Vin
They both promise to keep open wine fresh — but they do completely different things at completely different prices. Here's how each one actually works, and which is right for your kitchen.
The short answer
Buy Vacu Vin if
- You finish most bottles within 2–3 days
- You want a $15 fix — no subscriptions, no refills
- You drink mostly mid-priced bottles where a few days is enough
Buy Coravin if
- You pour by the glass and don't finish bottles
- You collect or own bottles you'd hate to oxidize
- You want to taste a special bottle without committing to it
Side by side
The differences that actually matter.
| Feature | Vacu Vin | Coravin Timeless |
|---|---|---|
| How it works | Pumps air out of the bottle | Pours through the cork using argon gas |
| Cork stays in? | No — pulled, then re-stoppered | Yes — never leaves the bottle |
| Freshness extension | 2–4 extra days | Weeks or months |
| Works on sparkling? | No | Only with the dedicated sparkling system |
| Setup time | 5 seconds | 1 minute |
| Ongoing cost | None | Argon capsules (~$3 per pour) |
| Price tier | Under $20 | $200+ |
The mechanism explained
Vacu Vin: remove the air
After pouring, you stopper the bottle with a one-way valve and pump until you hear a click. The pump removes most of the oxygen above the wine, slowing oxidation. Wine still ages — just slower.
- Fast, simple, virtually unbreakable
- No batteries, refills, or maintenance
- Doesn't work on sparkling wine
- A vacuum can pull volatile aromatics out of delicate wines
Coravin: replace the air
A thin needle pierces the cork. As wine pours out, argon — an inert gas heavier than air — fills the space. When you remove the needle, the cork reseals itself. The wine never meets oxygen. Bottles stay drinkable for months.
- Wine ages naturally as if untouched
- Lets you taste expensive wines by the glass
- Significant upfront cost + ongoing argon capsules
- Only works on natural cork (not screw caps or synthetic)
