Nendo Designs Dual-Tab Beer Can for the Perfect Pour

It yields a 7:3 beer-to-foam ratio

The Japanese market has a taste for both beer and precision. In an effort to check both boxes, Nendo has designed a beer can with a two-tab system that enables, in their reckoning, the perfect pour.

To explain their goal:

"Beer heads are considered essential for having beer taste better, at least in Japan. It is because a layer of foam with adequate thickness acts as a lid to prevent beer from coming into contact with the air, and keeps it from releasing aroma, flavor, and carbonation."

"There are two main [bubble-causing factors]: the sudden drop in pressure inside the can when it is opened and the friction that occurs between the can and the liquid when pouring. Through our study, it has been found that if the pull tab doesn't fully open the can, the pressure is concentrated in the narrow opening. At the same time, when pouring, the area of the beer in contact with the lid increases, which facilitates the formation of bubbles.

"Based on the research, a new can was designed with two pull tabs…. Slightly different distances between each pull tab and the lid change the degree of opening. When the can is opened by the first tab, the lid opens a little to create more foam. Once the glass is about half full of bubbles, stop pouring and wait for the bubbles to settle. Then open the second tab, which opens the lid to the fullest, and gently pour the rest under the foam. In this way, a glass with a liquid-foam ratio of 7:3, so-called golden ratio, can now be easily achieved with canned beer."

It's a safe bet that should this invention be commercialized, it will not make its way to U.S. shores; it requires both reading instructions and patience, which aren't exactly American traits.

The majority of the population is also right handed, so if they're not diligent with the directions are more likely to open tab 2 first since it's closest to that tab releasing pointer finger.

This sounds entirely like an education problem, if we can truly call this a "problem" worth solving. Once you know that the tab needs to be pushed further back after half the pour, the need for the 2nd tab becomes unnecessary. And the thing is, this isn't even an intuitive design! Every beer drinking bro out there would need to have it explained to them for it to even work... I just checked to make sure this wasn't posted on April 1st, but nope, it's "real."

Pretty much the dumbest thing ever. You either know how to pour a beer or are ain't care.

The beer most people drink in the US is yellow water. This won't help.
