Did you know that current wine bottle design dates back to the 1800s? That means, for over 200 years, absolutely nothing has changed, including a wine bottle's tendency to drip. Imagine if modernists hadn't modified cars since the Model-T. No one would stand for it. Similarly, it is time to have our wine bottles, who protect our favorite precious liquid, improved. Especially since they still have that nasty habit of dripping everywhere.
Anyone who drinks wine knows how frustrating it is to have those stray drops tumble off the side of a wine bottle neck. Despite your very best efforts, there always seems to be a stain or two on your table at the end of the evening.
Sure you could really class up the presentation and wrap a napkin around the neck of the bottle to catch the drips. You could even purchase one of those handy wine bottle inserts to help you pour drip-free.
However, all of that requires an extra step that can just seem so cumbersome when all you really want is a nice glass of adult grape juice after a long day at work.
An Inventor Solves the Problem
Thankfully, inventor Daniel Perlman devised a solution. As an oenophile and an inventor, naturally, his irritation with dribbles inspired him to invent a drip-free wine bottle.
Perlman claims he set himself to the task because he didn't want consumers to have to take an extra step to prevent drips after they had taken their bottle home. "I wanted to change the wine bottle itself," he told Brandeis. "I didn't want there to be the additional cost or inconvenience of buying an accessory."
For the last three years, this inventor has dedicatedly studied the physics of wine bottle dribbles from every angle. In slow motion, double time, and upside-down, he observed how people poured wine. Eventually, he concluded that wine tended to curl backward over the lip and run down the side because of the bottle's glass, which is hydrophilic. That means it actively attracts water.
To solve this problem, he concluded that it was best to break the continuity of the glass. Using a diamond-studded tool, he carved a groove around the circumference of the bottleneck just below the lip. He discovered that while a droplet of wine would normally run down the side of the bottle, if it encounters this groove, its path is effectively stopped. Instead of continuing downward, it will fall into the glass below.
In order to ensure that this pattern held true for every pour, Perlman experimented with several variations on depth and height of the groove. In the end, he found the perfect width to be roughly 2 millimeters, and the depth to be roughly 1 millimeter.
Now he is working with bottle manufacturers to have his design adopted into mainstream production. That means that soon your average at-home-sommelier may be able to enjoy a drip-free pour any day of the week.
