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.
