Behold the drip-free wine bottle!

Wine drip stains on white tablecloths have a new nemesis and his name is Daniel Perlman. The biophysicist at Brandeis University discovered that all it took to eliminate the bane of (red) wine pourers everywhere is to etch a small groove at the top of the bottle under the lip. We can but hope this catches on widely.

Professor Perlman studied slo-mo videos of wine being poured from a bottle. He found that drips cling to side of a bottle because bottles are hydrophilic! Now if that sounds more than PG-13, don’t worry: it just means that the glass of the bottle attracts the drops of water (or wine) that then annoyingly cling to the side and make a big mess. He found that cutting a 2mm groove in the bottle with a diamond-studded cutting tool just below the lip was sufficient to break up the attachment issues between the glass and the wine. Behold the drip-free wine bottle! No wonder Perlman has 100 patents.

If this is effective and can be widely commercialized, then Perlman would have earned our enduring admiration–as well as a hallowed place at the eternal (stain-free) table aside Bacchus.

Editor’s Note: Every Thursday — call it Throwback Thursday if you’d like — we’ll pull a story from the more than a decade of NYCR stories and republish it. This week, I chose one of science editor Tom Mansell‘s great references pieces “Fermentation Winespeak.” Have you ever smelled grape juice? Not Concord or Niagara juice but grape must that’s about to become wine? It doesn’t smell like much. It’s kind of like fresh mown grass. How does this relatively un-aromatic juice evolve into complex, aromatic wine? Most everybody’s grapes are in (except for the ice wine grapes) and it’s now time for…
