You twist the bottle, or try to yank it up quickly after pouring a glass — we all struggle to drop wine bottles from dribbling down the side of the neck.
But turns out, all it took was some clever engineering to fix the perennial problem.
Daniel Perlman, an inventor and biophysicist at Brandeis University has showed off a bottle with a groove cut into its lip. The groove is what stops the liquid from running down the bottle.
There are already products designed to prevent wine dripping, but Perlman says he wanted to solve the problem without an additional accessary.
“I wanted to change the wine bottle itself,” he says. “I didn’t want there to be the additional cost or inconvenience of…an accessory.”
After numerous tests, Perlman came up with the perfect groove that a wine stream could not get past — measuring roughly 2mm wide and 1mm deep.
He is currently in discussions with bottle manufacturers about adopting his design.
According to Perlman, in order for a drop of wine to make it across the groove, it would need enough momentum to jump from one side of the groove to another, or travel up inside the groove against the force of gravity.
The design of our current wine bottle dates back to the early 1800s and hasn’t changed much since, so it looks like it took us just about 200 years to figure out how to stop wine from dripping.
