Simple hack to keep leftover wine fresh dubbed ‘life-changing’: ‘I swear by this’

No need to whine if you have leftover wine.

Sommelier Warner Boin Dowlearn is going viral for her easy at-home hack that allows you to keep leftover wine tasting its best.

The first winemaker she worked for taught her to pour it into a smaller, half-bottle and recork it, but since most people don’t have a half-bottle lying around at home, she modified the method the trick to make it accessible to everyone.

She revealed her Mason jar method on TikTok, where she’s known as @confidenceuncorked, and has garnered over 2.7 million views

“I know it sounds crazy but if you ever have an instance where you have leftover wine, don’t put the cork back in the bottle,” she began the video, which was originally posted in 2023 and has gone viral again.

Dowlearn explained that if you were to put the cork back on a bottle of wine that’s half empty, half of it still has oxygen inside of it, and since corks are porous, it will allow more oxygen to get into the wine, which is “not great.”

She shared that the trick to keeping leftover wine tasting good is reducing the oxygen-to-wine ratio — and she recommends using a Mason jar to do so.

The hack is simple: Pour your wine into a Mason jar or any airtight container, like a kombucha container, and seal it tightly.

When the wine is in something airtight like a Mason jar, there is significantly less oxygen than there would be in the bottle.

“I swear by this,” she declared. “It will make your wine still taste fresh even a couple of days after you’ve opened it.”

“Don’t knock it ’til you try it.”

Many comments laughed at the idea of having leftover wine — and Dowlearn did quip in the video that “leftover wine might sound like a myth, but for some people it happens.”

But many people shared that they use this trick, too, as well as suggesting some other storage methods.

“I do this all the time! I’m glad it’s sommelier approved,” one person wrote.

“I use a clean beer bottle with a bottle capper, myself. keeps a long time,” a user suggested.

“I just tried this and highly recommend. I will be doing this from now on,” one shared.

“Yes!! This works so much better! Though it’s usually the glass I’m too tired to finish,” another said.

“This information is life-changing,” someone commented.

“This is the mason jar meal prep content I’ve been waiting for,” someone joked.
