Quick Answer: Opened wine lasts from about 1 to 7 days, depending on the style, when it is stored properly. Kendall-Jackson gives 1 to 3 days for lighter reds and sparkling wine, 2 to 3 for full-bodied whites, 3 to 5 for lighter whites and 4 to 5 for full-bodied reds. Bonterra's ranges are close but not identical. Black Box says boxed wine keeps up to six weeks once opened and refrigerated.
There is no single answer to how long wine is good after opening, because the style matters more than the label. This guide gives the ranges two wineries publish, what moves a bottle up or down within them, how to tell when it has turned, and what the fridge and a stopper change. How to close the bottle in the first place is covered in the bottle sealers guide. A sealed bottle is a different question: Kendall-Jackson says most wine is meant to be drunk within a year or two of purchase.
How long does each style of wine last after opening?
The table shows the two ranges side by side. Sources: Kendall-Jackson's guide to storing open wine (updated December 2024) and Bonterra's guide (March 2025), both read September 2026.
| Style | Kendall-Jackson | Bonterra |
|---|---|---|
| Lighter-bodied reds, such as Pinot Noir | 1 to 3 days | 2 to 3 days |
| Medium-bodied reds, such as Merlot and Zinfandel | Not given | 3 to 4 days |
| Full-bodied reds | 4 to 5 days | 4 to 5 days |
| Full-bodied whites | 2 to 3 days | 4 to 5 days |
| Lighter, crisp whites | 3 to 5 days | 5 to 7 days |
| Dry rosé | 3 to 5 days (blush rosé up to 7) | Not given |
| Sparkling wine | 1 to 3 days | 1 to 3 days (prosecco and other tank-method wines within 24 hours) |
Both are wineries describing guidelines, not a standard. Bonterra's page also carries a summary list with different figures, such as 4 to 7 days for full-bodied reds and 3 to 5 for full-bodied whites, so treat every range as approximate.
What makes one open bottle last longer than another?
Air, mainly, and how the wine is built. Bonterra says tannin, acidity, alcohol and residual sugar all help a wine hold up, and that older wines are more fragile once open. Kendall-Jackson says a fuller bottle keeps better than a nearly empty one, every reopening shortens the life, and wines labeled no or low sulfur tend not to last. Bonterra adds that a screw cap closes tighter than a cork. Pouring leftovers into a 375 ml half bottle cuts the air the wine touches, according to Kendall-Jackson.
How can you tell an open bottle has turned?
Look, smell, then take one small sip. Kendall-Jackson says opened reds turn brick or brown and whites turn darker yellow or gold, and to check whether the fruit still smells lively or the wine smells like vinegar. Bonterra also lists cloudiness and unexpected bubbles in a still wine, which point to refermentation. Kendall-Jackson says a wine that turns simply becomes vinegar.
Do the fridge, a stopper or a pump make it last longer?
The fridge does. Kendall-Jackson says to refrigerate opened whites, rosés and reds, and to take a red out about half an hour before serving. Bonterra says refrigeration slows oxidation and keeps most opened wines lively for up to a week. Stoppers and pumps are also recommended by Kendall-Jackson, whose informal week-long trial of wine preservers found that a hand pump kept a Chardonnay and a Cabernet closest to freshly opened. That was one taster and two wines, not a lab study.
What about boxed wine, port and sherry?
They follow different rules from bottled table wine. Opened spirits are a separate subject, covered on pourspoutcover.com.
| Format | Guidance | Source |
|---|---|---|
| Boxed wine, opened | Up to six weeks, refrigerated | Black Box Wines |
| Vintage port, opened | 2 to 3 days | Kendall-Jackson |
| Fresh sherry such as Fino and Manzanilla | An exception to the long life of fortified wine; no figure given | Kendall-Jackson |
| Fortified and sweet wines in general | 2 days to years, depending on the wine | Kendall-Jackson |
The Black Box page is one brand's guidance. It adds that the coolest part of the house is the fallback if the fridge is full, at the cost of a shorter life.

Frequently asked questions
Does opened wine go bad?
Yes. Kendall-Jackson says a wine left open too long turns into vinegar. Before that it fades: the fruit goes flat and the color darkens. Sniff it, then taste a small sip, and trust what you find.
How long does wine last after you open it?
Kendall-Jackson says anywhere from a day to several weeks, depending on the type. For most table wines that means about 1 to 7 days. Boxed wine is the long one, at up to six weeks refrigerated according to Black Box.
How long does wine stay good after opening in the fridge?
Bonterra says refrigeration keeps most opened wines lively for up to a week. Kendall-Jackson also says to refrigerate. Its style ranges run from 1 to 3 days for delicate reds and sparkling wine to 5 days for fuller reds and lighter whites.
Does wine expire?
Kendall-Jackson says most wine is meant to be drunk soon after you buy it, certainly within a year or two. An open bottle changes faster, so use the ranges above once the cork is out.
When does wine go bad?
Once it has had too much air or heat. Bonterra lists browning, cloudiness, a stewed-fruit or sherry-like smell and a vinegar smell as signs an opened wine has passed its peak. Kendall-Jackson says wines labeled no or low sulfur tend not to stay fresh long after opening.
Should I refrigerate red wine after opening?
Kendall-Jackson says yes: the cold slows oxidation, and a red can come out of the fridge about 30 minutes before you serve it. It warns that delicate reds such as Pinot Noir can taste flat after a few days there.
How long does boxed wine last after opening?
Black Box says up to six weeks when the opened box is kept in the fridge. Its bag collapses as wine is dispensed, which limits air. Kept warmer, the same page says the shelf life may be shorter.
