Is There Any Point in Letting Red Wine Breathe?

At the end of a long day, few things beat simple pleasures like watching a good film, eating a bar of chocolate the size of your head, or drinking a big glass of red wine.

By this point in the evening, most people don’t want to be told that they need to uncork the bottle and let the wine sit for at least 30 minutes before it becomes pleasantly drinkable. Yet that's (by the letter of the unwritten law) what you're supposed to do.

But why? Well, let's start with the assorted historical reasons.

Red wine has been around since the Stone Age. In fact, in 2011 a cave was uncovered in Armenia where the remains of a wine press, drinking and fermentation vessels, and withered grape vines were uncovered; the remains were dated at 5500 years old. Early winemaking often had a ritualistic aspect: Wine jars were found in Ancient Egyptian tombs, and wine appears in both the Hebrew and Christian bibles.

The concept of letting wine "breathe" is, historically speaking, relatively new and probably has its roots in the way wine was once bottled and stored.

Traditionally, sulfur is added to wine in order to preserve it for longer, and if too much is added the wine might well have an ... interesting aroma when first opened—the kind of "interesting aroma" that bears more than a passing resemblance to rotten eggs. Contact with the air may have helped to remove the smell, so decanting wine may once have been a way of removing unwelcome odors, as well as getting rid of the sediment that built up in the bottom of bottles.

It’s also possible that the concept springs from the early 1860s, when Emperor Napoleon III asked Louis Pasteur to investigate why so much French wine was spoiling in transit. Pasteur published his results, which concluded that wine coming into contact with air led to the growth of bacteria, thus ruining the vino. However, small amounts of air improved the flavor of the wine by "aging" it. In bottles, with a cork stopper, the wine still came into contact with a small amount of oxygen, and by storing it for years the wine was thought to develop a deeper flavor.

However, how much of that actually matters today?

Many experts agree that there is no point in simply pulling out the cork and letting the wine sit in an open bottle for any period of time; the wine won’t come into enough contact with oxygen to make any difference to the taste.

However, decanting wine might still be a useful activity. The truth is this: It entirely depends on the wine.

Nowadays we don’t really age wine anymore; we make it with the aim of drinking it quickly, within a year or so. But some types of wine that are rich in tannins (compounds that come from the grape skins and seeds) can benefit from a period of time in a decanter, to soften the astringent taste. These include wines from Bordeaux and the Rhône Valley, for instance.

If you really want to know if a particular wine would benefit from being given time to breathe, try your own experiment at home. Buy two bottles, decant one, and let it breathe for an hour. Do you notice a difference in the taste? Even if you don’t, it's an experiment that justifies opening two bottles of wine.

One word of warning: No matter where a wine comes from, it is possible to overexpose it to oxygen. So remember Pasteur’s experiments and don’t leave your wine out of the bottle for days. That, friends, would be one hell of a waste.

Why Are Shower Doors in Hotel Rooms Getting Smaller?

Shower doors are shrinking in posh hotels, and minimalism is to blame, Condé Nast Traveler reports.

In lieu of hanging shower curtains or providing full shower doors, many newer hotels are opting for glass panels that cover only half the length of the shower. That’s frustrating for many travelers, who complain the growing trend is inconvenient and leaves bathroom floors sopping wet and slippery after shower use.

According to Condé Nast Traveler, the half-door trend began in European hotels in the 1980s. “A lot of it comes down to people trying to design hotel rooms with limited space,” boutique hotel designer Tom Parker told the magazine. “It’s about the swing of the shower door, because it has to open outward for safety reasons, like [if] someone falls in the shower. You have to figure out where the door swing’s going to go, make sure it’s not [hitting] the main door. It’s just about clearances.” A smaller door also has the added benefit of making the space appear larger than it really is, according to the magazine.

The trend is also connected to the birth of minimalist “lifestyle hotels,” which cater to a younger, hipper clientele that gravitates toward sleek lines and modern design. Plus, half-size glass doors are easier to clean than shower curtains, which tend to trap bacteria and need to regularly be replaced, which can add up to significant additional costs for a hotel.

Theoretically, even half-door showers are designed to minimize water spillage. Designers try to level the floors in bathrooms so water doesn’t pool in random areas, and they place shower heads and knobs in areas that are more protected by glass paneling. And where design doesn’t work, hotels try to pick up the slack.

“Hotels tend to mitigate the risks by offering non-slip interior shower mats, cloth bath mats for stepping out of the shower, grab bars, [and] open showers or no-sill showers which avoid having to step up and over the ledge,” designer Douglas DeBoer, founder and CEO of Rebel Design Group, told Condé Nast Traveler.

But the half-door trend still has yet to gain much love from hotel guests. “The older generation much, much prefers having a shower door,” Parker told Condé Nast Traveler. “I’m like a 70-year-old man at heart anyway. I like [a shower door] if it’s in keeping with the style of the rest of the room.”

Does Pushing the Button at a Crosswalk Actually Do Anything?

Since crosswalk signals rarely seem to give you the green light (or more accurately, the white, human-shaped light) right after you press the button, you may find yourself wondering if those buttons actually work. The potentially exasperating answer is this: It depends.

First and foremost, it’s important to understand that crosswalk buttons aren’t designed to have an immediate effect; they’re just supposed to tell the system that a person is waiting to cross. As CityLab explained, some systems won’t ever give pedestrians the crossing signal unless someone has pressed the button, while others are programmed to shorten the wait time for walkers when the button has been pressed. No matter what, the system still has to cycle through its other phases to give cars enough time to pass through the intersection, so you’ll probably still have to stand there for a moment.

During busy traffic times or under other extenuating circumstances, however, cities can switch the system to what’s known as “recall mode,” when pedestrian crossings are part of the cycle already and pressing the button quite literally changes nothing. Unfortunately, there’s no way to tell if a particular button is in recall mode, short of calling your city officials and asking an expert to come inspect it.

But if you feel like a button isn’t doing anything, there’s a pretty good chance it’s been permanently deactivated. As congestion has increased and the systems to manage it have become more advanced over the years, cities have moved away from using crosswalk buttons at all. In 2018, for example, CNN reported that only around 100 of New York City’s 1000 buttons were still functioning. Since actually removing the buttons from crosswalks would be a costly endeavor, cities have opted to leave them intact, just waiting to be pummeled by impatient pedestrians who don’t know any better.

What about 'close door' buttons on elevators, you ask? That depends, too.
