Booze Without the Burn? An Enzyme-Tinkering Startup Aims to Make Spirits Smoother

Booze Without the Burn? An Enzyme-Tinkering Startup Aims to Make Spirits Smoother


In the world of professional spirits reviews, “smooth” is something of a dirty word. Consumers, on the other hand, absolutely love to use it.

The implication of “smooth” is simple; it suggests a product doesn’t hurt when you drink it. It’s such a sought-after quality that the distilling industry will do just about anything to achieve it. Some methods are respectable, like aging a whiskey for 15 years to file down its rough edges. Some are less so, like dumping in loads of chemical additives. Some are more successful than others, but none can completely eliminate that burning sensation in your mouth.

But it wasn’t until Joana Montenegro and Martin Enriquez, the spousal founders of Voodoo Scientific, that anyone really asked: Why does alcohol burn, anyway? And, most importantly, is there a way to get rid of that gasp-inducing burn altogether?

Conventional wisdom and common sense would suggest that ethanol is what makes that ill-advised shot of firewater sear your mouth and throat so badly, but it turns out that’s not the case. During the months of Covid-19 lockdown, Enriquez, a former telecom executive, says he and Montenegro, essentially on a lark, had the idea to dig deep into this question. They started by scouring the scientific journals to see if anyone had pinpointed the reason why whiskey and its ilk can cause an unpleasant burn. No one had. “Nobody could describe the compounds that make that harsh, painful bite,” he says. “No one could really identify what it is that attacks you and creates pain.”

Montenegro, a veteran food scientist from General Mills and Land O’Lakes, said they decided to go deeper. “We said, ‘Let’s go back and find the specific receptor in the mouth that’s being triggered by the spirit,’” she says.

To do that, the duo started by contacting David Julius, the head of physiology at UCSF, to discuss the line of inquiry. Masked and 6 feet apart in a Starbucks, Montenegro says, Julius didn’t comprehend why someone who was part of the team that patented Go-Gurt had an interest in pain receptors. Nevertheless, the duo persisted, and Julius eventually guided them on how to research the concept and determine which receptor was being activated to cause a pain response. Eventually Montenegro and Enriquez found it, a receptor called TRPA1.

Once a negative receptor like this is identified, traditional food science has a solution for dealing with it: You block the receptor with a chemical. It’s the typical way that sweetness and bitterness can be masked in foodstuffs, by just covering it up with something stronger. Alas, that didn’t work for hiding the burn of alcohol. “This receptor has a very unique property called reversible bonding,” says Montenegro. “It’ll bond to a thing, it’ll give you a jolt, and it’ll let it go—and then it’ll bond to another one.” This is why alcohol continues to burn sip after sip.

“In other words, you can’t block it,” she says. “It’s designed to continuously alert you that you’re consuming something that is an irritant.”

The Best Babbel Promo Codes and Deals for April 2026


I’ve been trying to become fluent in Spanish for the last decade. After spending most of my adult life surrounded by multilinguals, I often feel like I’m playing an impossible game of catch-up. Like everyone else, I’ve tried to become regimented with practicing on an in-phone app like Duolingo, which attempts to ‘game-ify’ language learning, but mostly ends up with a sad and sick-looking green bird icon guilting me to practice every time I open up my phone.

Babbel aims to help people actually learn the language through practical conversation and grammar, using proven pedagogical methods and speech recognition technology. Each lesson is short, with 10 to 15 minute lessons developed by a team of over 150 linguists.

No more excuses—we’ve got a Babbel promo code and a Babbel coupon to help you hit your goals. Maybe you’ll be fluent by your next vacation (or at least able to order a chopped cheese with confidence at the bodega).

Robotaxi Outage in China Leaves Passengers Stranded on Highways

Robotaxi Outage in China Leaves Passengers Stranded on Highways


An unknown technical problem caused a number of robotaxis owned by the Chinese tech giant Baidu to freeze on Tuesday in the middle of traffic, trapping some passengers in the vehicles for more than an hour.

In Wuhan, a city in central China where Baidu has deployed hundreds of its Apollo Go self-driving taxis, people on Chinese social media reported witnessing the cars suddenly malfunction and stop operating. Photos and videos shared online show the Baidu cars halted on busy highways, often in the fast lane.

A college student in Wuhan tells WIRED that she was stuck in a Baidu robotaxi with two friends for about 90 minutes on Tuesday. (She asked to be only identified with her last name, He, to protect her privacy.) The student says the car malfunctioned and stopped four or five times during the trip before it eventually parked in front of an intersection in eastern Wuhan. Luckily, it was not a busy road, and the group was not in immediate danger. The screen display in the car asked the passengers to remain in the car with seatbelt on and wait for a company representative to come “in five minutes,” according to a photo He shared with WIRED.

He says it took about 30 minutes to reach a Baidu customer representative on the phone. “They kept saying it would be reported to their superior. But they didn’t explain what caused [the outage] or let us know how long we needed to wait for the staff to come,” He says. But no one ever came, and after another hour of waiting, the three passengers decided to just get out and go home by themselves (the doors weren’t locked).

On Chinese social media, other passengers also complained about being unable to reach Baidu’s customer support. “I tried every way I could think of to call for help using the options the app showed, but the phone line wouldn’t go through, and when I pressed the SOS button it told me it was unavailable. So then what exactly is the SOS for?” wrote one person in a post on RedNote alongside a video showing the button not working. She said she had to force the door to open and get out of the car as traffic halted to a complete stop behind her robotaxi. “Apollo Go, you really owe me an apology,” she wrote.

Baidu didn’t immediately respond to a request for comment. Local police in Wuhan issued a statement around midnight in China that said the situation was “likely caused by a system malfunction,” but the incident is still under investigation. No one was injured and all passengers have exited the vehicles, the police added. It’s unclear how many of Baidu’s robotaxis may have been impacted.

One dash cam recording posted to RedNote shows a car passing 16 Apollo Go vehicles parked on the road in the span of 90 minutes. On several occasions, the video shows the driver narrowly avoiding hitting the robotaxis by braking or changing lanes at the last minute.

Others were apparently not as fortunate. In another RedNote post, a man claimed he crashed into one of the malfunctioning Baidu vehicles. The man wrote in the caption that he was driving over 40 mph on a highway when the car in front of him suddenly changed lanes to avoid the stopped robotaxi. He couldn’t react fast enough and ended up running into the self-driving car. Photos of the man’s orange SUV being towed away show that the car’s front-right fender was completely torn off, and other parts appeared to have sustained major damage.

Airmega Mighty AP-1512HH

Despite its low price tag and squat stature, the Airmega Mighty is capable of cleaning a substantial amount of space. At full bore, it can handle a 361-square-foot space, although you’ll get the best performance, and save your ears, if you’re closer to a 200-square-foot room. If you don’t want it running constantly, there are built-in timers to automatically shut off after 1, 4, or 8 hours, or you can use Eco Mode, which will run until the Might doesn’t sense any dirty air for half an hour.

That’s right, the Airmega Mighty has a built-in air quality sensor, and it reflects the current state of the air quality using a colored light with three levels. It uses those readings to automatically adjust the fan speed and timing settings on the fly, as well as giving you a peak into how bad the air you’re breathing right now is for you. While it lacks integration with smart home setups like Google Home, it makes up for it by handling all of its own business without Wi-Fi or extra apps on your phone.

While the Coway Airmega Mighty is available in three colors, only the black and silver model is currently discounted, so you’ll have to pay full price if it doesn’t match your living room’s color scheme. We’ve put in the work testing every air purifier we could get our hands on, so make sure to check out the full guide if you’re trying to clean up your space. The Coway is discounted as part of Amazon’s Big Spring Sale, and we’ve got the best deals from products we’ve tested gathered in one place if you want to save some bucks.
