But which is actually better: bottles under cork, or bottles under screw cap?
Business Insider recently spoke with James Harbertson, a Washington State University professor of enology - that's the study of wine - to ask him some of our most embarrassing questions about wine. On the topic of screw-cap wines, his answer was clear: No, they are not inferior to corked wines, and in some ways might actually keep your wine from spoiling.
While many bulk wines use screw caps - which is likely where the stigma originated - a screw cap is by no means and indicator of the quality of your wine.
In fact, any high-end wines also bear a twist-able top. For example, New Zealand has been transitioning to the twist-off style in recent years. Harbertson said that the screw-top is just as effective as cork at keeping air out.
Why wine bottles typically use cork
There are lots of reasons to use cork instead of a screw-cap. Cork is made from bark, which makes it a renewable resource. Plus, it can form to the shape of a wine bottle, making it an incredibly appealing way to seal wine.
But there's a drawback: Occasionally bad cork can get into the wine, something called "cork taint." It's not going to harm you necessarily, but it will make the wine taste or smell a little funky, like moldy cardboard. Some people are fine drinking that wine, but others - like Harbertson - can't stand it. It's why New Zealand decided to switch from cork to screw after getting fed up with bad cork that kept causing this cork taint.
And interestingly enough, a 2013 study that looked into why cork tainted wine smells so bad found that it was because a certain chemical called "2,4,6-trichloroanisole" that's known to induce cork taint actually suppresses smell rather than create the off-putting odor.
So in the end, going for the screw-cap style wine bottle might be the safest way to go. Unless you'll terribly miss the pop of a cork coming unstopped.
