Which is Better: Bottles With Cork or Screw Cap?
James Harbertson, a Washington State University professor of enology said..
“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, some high-end wines also use a twist-able top, and a screw cap is by no means an indicator of the quality of your wine. Harbertson also said that the screw-top is just as effective as cork at keeping air out.
Cork vs Screw
Cork is made from bark, although expensive, it forms to the shape of a wine bottle nicely. 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.
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.
According to Harvey Steiman of the Spectator
“Stalwarts such as Chehalem, WillaKenzie, Willamette Valley Vineyards, Maysara, Patton Valley, Raptor Ridge, Boedecker, Sineann, Siduri, Argyle and Roco consistently rate in the 90-plus range in my tastings, employing twist-offs.”
There are some high end and low end producers that may never employ a twist off, no matter any benefit. Although in the end, going for the screw-cap style wine bottle might be the safest way to go… but you may miss the tradition that goes along with popping a cork on your favorite bottle of vino.

Four more thoughts on wine and screw caps (Warning: This gets geeky) – SFGate (blog) Under these circumstances, it’s possible that a wine bottled under a perfectly healthy cork, or under screw cap or synthetic cork, could suffer from TCA. However, TCA from non-cork sources is pretty rare. Wineries no longer clean with chlorine products.
