Why Do Champagne Corks Expand After the Bottle is Opened?

Why do champagne corks expand after opening the bottle?

Kyle Kurani:

It all depends on how long the cork has been in the bottle. Champagne starts its life with a crown cap (a beer bottle top) with a little yeast and sugar inside to make it bubbly. After staying under that cap for at least 15 months (the law in champagne), it then gets disgorged and the cork that we see gets put inside, then shipped over to us. That cork is just one big cylinder, uniformly shaped; they all start out looking like the one below. Since most champagne is consumed relatively quickly, the cork doesn’t have time to compress; it wants to go back to the size it was when it was forced in.

If you ever open an older bottle of champagne—I have had some that has been “on the cork” for 30-plus years—the cork comes out shaped like a mushroom and does not expand at all. It has had plenty of time to get compressed and hold that shape. Even one or two years on the cork will make a noticeable difference in how much it can spring back or not.

As a side note, aging your non-vintage champagne for one year makes a huge difference in how the wine tastes. If you can afford to tuck a case in your closet for a year and start replacing the old ones with new bottles when you drink them, you will be greatly rewarded!

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.
