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.

drip-free-wine-bottleProfessor 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.

  1. This is quite helpful. To be honest, I was quite reluctant to pour wine with my friends since I might spill it to them. Now this tip can help me.


  2. It will be interesting to see if this invention catches on. I’m not sure how many people are actually concerned about wine spills as they poor. Making a note to myself to see how much “spilling” I do!
