Whether you consider yourself a wine connoisseur or only enjoy the beverage on occasion, you’ve likely encountered the frustrating drip coursing down the neck of the bottle. Most restaurants solve the issue by wrapping a napkin around the bottle’s neck or using a specialty product, but one biophysicist wasn’t satisfied with those solutions.
Dan Perlman, a biophysicist with Brandeis University, decided that he wanted to create a solution that would resolve the issue of wine spilling down the side of the bottle that didn’t require an investment in other products.
As liquids are poured from the bottle, they tend to curl back, allowing the drip to run down the neck based on the hydrophilic properties of glass. However, Perlman, utilizing his skills as a scientist, decided to craft an alternative bottle design, eliminating the need for napkins or the various contraptions people often have to buy to avoid the issue.
“I wanted to change the wine bottle itself,” said Perlman, according to a report by Popular Mechanics based on information from the university’s website.
“I didn’t want there to be the additional cost or inconvenience of buying an accessory.
Perlman used a diamond-cutting tool to create a groove below the lip of the bottle, ensuring that a drip couldn’t make its way down the glass vessel.
“A droplet of wine that would otherwise run down the side of the bottle encounters the groove, but can’t traverse it,” according to a statement on the university’s website. “Instead, it immediately falls off the bottle into the glass along with the rest of the wine.”
“For a drop of wine to make it across Perlman’s groove, it would have to travel up inside the groove against the force of gravity or have enough momentum to jump from one side of the groove to the other,” the statement added.
