Quick Answer: Kendall-Jackson puts opened lighter-bodied whites at 3 to 5 days and oaked, full-bodied whites at 2 to 3 days. Bonterra gives 5 to 7 days for crisp whites such as Sauvignon Blanc and 4 to 5 for full-bodied Chardonnay, so the two disagree on fuller whites. Both say to refrigerate the bottle. These are winery guidelines, not a safety limit.
How long is white wine good for after opening? White wine gets the fridge by default, which helps, but the style still decides how many days you have. This post covers the ranges for whites and rosé, where to keep an open bottle, and how to tell when it has turned. For all styles together, see the general guide to how long wine lasts after opening. Reds have their own post: how long red wine lasts after opening.
How long does opened white wine last by style?
The figures come from Kendall-Jackson (updated December 2024) and Bonterra (March 2025), both read September 2026.
| Style | Kendall-Jackson | Bonterra |
|---|---|---|
| Lighter-bodied and crisp, such as Sauvignon Blanc | 3 to 5 days | 5 to 7 days |
| Full-bodied, such as oaked Chardonnay | 2 to 3 days | 4 to 5 days |
| Dry rosé | 3 to 5 days for lighter colors, 4 to 5 for darker | Not given |
| Blush or off-dry rosé | Up to 7 days | Not given |
The two wineries disagree most on full-bodied whites. Kendall-Jackson says oak-aged whites should often be enjoyed sooner and tend to smell flat more quickly, while Bonterra says a full-bodied Chardonnay can hold 4 to 5 days. Bonterra's own summary list differs from its sections, giving 3 to 5 days for full-bodied whites and 5 to 7 for light whites and rosés. Treat the ranges as approximate.
Where should you keep an open bottle of white wine?
In the fridge, with the closure back on. Kendall-Jackson says refrigerating open wine is close to all upside, since cold significantly delays oxidation, though the wine keeps changing. Bonterra suggests steady refrigeration at 45 to 50°F (7 to 10°C) for crisp whites, and says to avoid temperature swings. Kendall-Jackson's wine storage guide says a refrigerator hovers around 40°F (about 4°C). Neither names one exact setting, so the point is cold and steady.
Does a screw cap or cork make a difference?
A little. Bonterra says screw caps generally close more tightly than corks, which minimizes oxygen exposure, and that wider-necked bottles let in more air than narrow-necked ones. It notes that Burgundy-style bottles, used for Chardonnay, have wider necks than Bordeaux-style bottles. Kendall-Jackson says lighter whites closed with a screw top often benefit from a day or two of extra air, because most screw caps let less oxygen through than corks do.
If the cork will not go back in, Kendall-Jackson suggests keeping a few spare corks or glass stoppers, and using plastic wrap with a rubber band as a last resort. The options are laid out in the bottle sealers guide. Esatto does not sell wine stoppers. Its Pour & Seal pourers are made for bar bottles, not for wine.
How can you tell white wine has gone off?
Check the color, the smell, then one small sip. Kendall-Jackson says opened whites turn a darker yellow or even gold, and to check whether the fruit still smells lively or the wine smells like the vinegar in your pantry. Bonterra adds browning, cloudiness, unexpected bubbles in a still wine, which point to refermentation, and a nutty, sherry-like character as oxidation sets in.
When are these ranges wrong?
When the bottle is older, low on wine, or opened often. Bonterra says older wines are more fragile once open. Kendall-Jackson says more wine left in the bottle keeps better, each reopening shortens the life, and wines labeled no or low sulfur tend not to stay fresh long after opening. Pouring the leftovers into a 375 ml half bottle, filled to the top, reduces the air the wine touches.
Frequently asked questions
How long does white wine last once opened?
About 2 to 7 days depending on style, if refrigerated. Kendall-Jackson gives 2 to 3 days for oaked, full-bodied whites and 3 to 5 for lighter ones. Bonterra gives 4 to 5 for full-bodied and 5 to 7 for crisp whites.
Does white wine go bad after opening?
Yes. It darkens toward yellow or gold, the fruit fades, and it can start to smell like vinegar, according to Kendall-Jackson. Bonterra adds cloudiness and a nutty, sherry-like note. Smell it, then take one small sip.
Should you refrigerate white wine after opening?
Yes. Both wineries say so. Kendall-Jackson says cold significantly delays oxidation reactions in open wine, and Bonterra says refrigeration slows oxidation and keeps most opened wines lively for up to a week.
How long does Chardonnay last after opening?
The wineries differ. Kendall-Jackson gives 2 to 3 days for full-bodied whites fermented or aged in oak, which often smell flat sooner. Bonterra uses its Chardonnay as the example for 4 to 5 days.
How long does Sauvignon Blanc last after opening?
Bonterra gives 5 to 7 days and names Sauvignon Blanc as an example of a crisp white with acidity that helps it hold. Kendall-Jackson puts lighter whites with little or no oak at 3 to 5 days.
How long does rosé last after opening?
Kendall-Jackson says dry rosé is 3 to 5 days when it is light in color and 4 to 5 when darker, and blush or off-dry rosé can last up to 7 days. Bonterra's timeline groups light whites and rosés at 5 to 7 days.
Does a screw cap keep opened white wine longer than a cork?
Possibly. Bonterra says screw caps generally close more tightly and may extend freshness. Kendall-Jackson notes that most screw caps let less oxygen through than corks. Neither gives a number of extra days.
