The Strange Science Behind Why Alcohol Burns

If you’ve ever taken a shot of alcohol, you know that it comes with certain unexpected consequences—the surprising heat you feel as the liquid slides down your gullet, for instance.

The folks over at SciShow recently tackled the “why” behind alcohol’s burn, and the answer is surprising. It all starts with a receptor known as VR1, contained in our mouths and throats. High temperature foods trigger VR1, which then tells our nerves and brain what’s going on, and results in a burning sensation.

Capsaicin, found in spicy foods, interacts directly with these receptors, as does alcohol ethanol, though in a different way. Ethanol just makes them more sensitive. Your VR1 receptors activate at about 107°F, but ethanol lowers that to just 93 degrees. See where this is going? Body temperature is normally around 98.6°F, so when you feel that burning sensation, it’s because your body itself is now beyond the threshold for those heat receptors.

As host Hank Green says in the video above: “The next time you take a shot and your eyes start watering, just remember it’s not the booze that’s hot, it’s you”—which just might be the best brainy pickup line of all time.

New Pop Chart Lab Poster Is a Boozy Blueprint For Making Classic Cocktails

Pop Chart Lab

Pop Chart Lab's posters combine design with data, and their latest offering—a full breakdown of the ingredients in 60 classic cocktails—is no exception. From the exact ratio of gin and tonic that should go into a G & T (2 ounces and 4 ounces, respectively) to the garnishes you'll need to make a proper Tom Collins (a maraschino cherry and a lemon twist), the 3-foot-by-2-foot "Constitutions of Classic Cocktails" artwork teaches mixology basics you'd typically learn in bartending school, sans tuition fee.

In addition to mainstays like the Negroni and the Whiskey Sour, the poster also includes relatively obscure drinks (ever heard of the Golden Dawn, or the Journalist?), which you can attempt after drinking your way through your favorite concoctions. Before you know it, you'll be explaining to your friends the intricacies of why you should stir martinis instead of shaking them (sorry, James Bond), or the difference between a highball and a Collins glass. Bottoms up!

"Constitutions of Classic Cocktails" costs $37, and is currently available for pre-order. Shipping begins on Friday, October 20, 2017. (To see the poster's details up close, visit Pop Chart Lab's website and click on the diagram.)

Attention Beer Lovers: A London Brewery Is Hiring a Professional Taste-Tester

Beer lovers aren’t given many chances to discuss their passion for imbibing at job interviews. But a new open position at London's Meantime Brewing Company lists that expertise as one of the top qualifications. As Fortune reports, the brewery is seeking a professional beer taster to help improve its products.

The brewery’s part-time employee will “join the panel brewers as they taste, discuss, and pass opinion on a range of different beers,” according to the job listing on LinkedIn. On top of steady access to free booze three hours a week, the taster will receive a competitive salary “with beer benefits.” As the description reads: “Yes, this could just be the best job in the world.”

Meantime isn’t just considering any casual beer drinker for the role. Their ideal candidate will have a precise palate that can distinguish “chocolate malt from dark malt” and “Fuggles from Cascade hops.” They will also have an understanding of global consumer markets, a functioning knowledge of English, and an extensive beer vocabulary. The brewery is located in the London borough of Greenwich, so applicants who aren’t local should be willing to relocate.

Founded in 1999, the Meantime Brewing Company made its name on the beer scene with signature beverages like their London Lager, London Pale Ale, and Yakima Red. If you’re interested in joining the team, post 30 words on your LinkedIn profile explaining why you deserve the gig, along with any photos or videos that may help your case, with the hashtag #pickmemeantime. The company will narrow down the pool to three candidates for an in-person beer tasting before deciding their top pick. Meanwhile, you can prepare for the job by brushing up on your beer facts.
