The Science of "Breaking the Seal"

If you like beer, and like it in large quantities, this might be a familiar scenario: You sit down at the bar, get a beer and drink it. You drink another one. Maybe a third. Things have gone well up to this point, but now you have to pee. So you go. Once you return to your seat and keep drinking, though, it feels like you’ve crossed a point of no return, and you have to pee again and again.

You’ve "broken the seal." After that initial pee, you seem to have to run to the bathroom every 15 to 20 minutes for the rest of the night, and the urine just won’t stop flowing. What’s going on?

Part of what makes you pee so much while boozing is that alcohol inhibits arginine vasopressin, also known as antidiuretic hormone or ADH. ADH is made in the part of the brain called the hypothalamus, and then stored and released from the pituitary gland at the base of the brain. Its job is to conserve water in the body by reducing its loss in urine. It binds to receptors on the kidneys and promotes water reabsorption, a decrease in the volume of urine sent to the bladder, and excretion of more concentrated urine.

Alcohol throws a wrench into the works, though, and blocks certain nerve channels that help get ADH secreting out into your system. Without ADH carrying on about conserving water, the kidneys don’t reabsorb water as easily and excess water winds up getting dumped into urine to leave the body. With alcohol keeping ADH from doing its job, you produce a lot more water-diluted urine, which fills the bladder quickly and makes you have to pee more often.

So, there’s really no seal to break, no dam to crack open. If anything, the damage was done when you took your first drink and started suppressing your ADH, not when you took your first pee.

Keep Going

But how come you can hold your pee just fine until that first bathroom break, and then it seems you have to go constantly?

First, it takes a little bit of time for alcohol to suppress ADH and for the kidneys to ramp up the water works. When you crack open your first beer, you may have some urine in your bladder already, but also some ADH in your system to keep things from getting out of hand. As you continue to drink, though, your ADH levels drop and your urine production increases. By the time your bladder has filled and you're ready to go to the john, you’ve probably had a few more drinks. Your ADH is more suppressed and your kidneys are working at full tilt, so you’re going to have to go more often.

Additionally, alcoholic beverages can be a bladder irritant for many people and the carbonation of drinks like beer and champagne can cause gas and pressure that contribute to that irritation. As your bladder fills up again after the initial pee, all that irritation can create a very strong urge to pee some more and make your bladder feel fuller than it really is, sending you running to the bathroom over and over again throughout the night.

11 Common Misconceptions About Beer
Original image

If beer only conjures up images of frat boys pounding cans of the cheap stuff or doughy sports fans reveling in the alcoholic refreshment before, during, and after a big game, think again. Beer has come a long way, baby, and many of the preconceived notions about the beverage are decidedly unfair, as evidenced by the following 11 fabrications.

1. BEER SHOULD BE SERVED ICE COLD.

All of those neon ice cold beer signs are actually bad news for beer drinkers. To properly enjoy their beer, it should be served at 44 degrees Fahrenheit (with a little leeway depending on the type of beer you’re drinking—a barrel-aged Stout, for example, should be served only lightly chilled). The reason is that taste buds become dead to the taste of the drink when it is served any colder, which means you’re not really tasting anything or getting the most enjoyment out of your beer.

2. FROSTED BEER MUGS KEEP IT CLASSY.

Piggybacking on the falsehood that beer should be guzzled cold, it also shouldn’t be served in a frosted beer mug. Would you serve wine in a frosted glass? No. An intensely cold beer mug will also numb your senses to the taste of the beer.

3. ALL DARK BEERS ARE HEAVY.

If you’ve been avoiding dark beers because you fear their intensity, you’ve been sorely misguided. “People naturally assume they are heavier,” says Hallie Beaune, a rep for Allagash Brewing Company and author of The Naked Pint: An Unadulterated Guide to Craft Beer. “I think it’s that connection to Guinness, which promotes itself as creamy and almost like a meal, that’s the feeling they give in their commercials. For a lot of people that’s the first dark beer they’ve had so they assume they’re all similar when, really, dark beers are just dark because of the roast level of the malt that’s used in the beer.”

4. GUINNESS IS INHERENTLY FROTHY.

Sure, Guinness is served all creamy and delicious-looking, but Beaune explains it has less to do with the beer itself and everything to do with the tap most stouts use, which has more nitrogen than the standard tap (generally a mix of nitrogen and CO2). To deliver all that frothiness, a stout faucet, which has a long, narrow spout, is used.

5. DRINKING BEER FROM THE BOTTLE IS THE BEST WAY TO ENJOY IT.

Sure, a bottle may look more refined than a can, but it’s still not the appropriate vessel. “Drinking beer from the bottle is another no-no, mostly because what you taste comes from your olfactory senses from your nose, so if you take a sip of something from that kind of bottle your nose isn’t participating at all,” says Beaune. “It’s too small for you to get a whiff of the beer. Just like if you were drinking red wine out of a wine bottle, you wouldn’t really be able to evaluate that wine.”

6. YOU CAN STORE BEER ANYWHERE.

Think again! All beer should be stored in a refrigerator. It responds best to cold, dark storage.

7. "SKUNKY" IS JUST A CUTE WORD FOR BEER GONE BAD.

There is actually a reason why seemingly rancid beer is termed "skunky." “Light can hurt beer—they call it lightstruck,” says Beaune. “The light interacts with the hops in beer (the four ingredients in beer are malt, water, hops and yeast), and it can actually have this chemical reaction that creates a smell that’s the same as a skunk gives off, which is why you hear about skunky beer.”

8. ALL BEER BOTTLES ARE CREATED EQUAL.

Darker bottles are important. Clear or green bottles may be pretty, but they’re not doing much to protect your beer from light. Dark beer bottles work best to help retain its intended flavor.

9. CANNED BEER MEANS CHEAP BEER.

Cans are actually a great way to protect beer, but in the old days they would often give the beverage an aluminum taste. “Most of the cans the craft breweries are using nowadays have a water-based liner so the beer isn’t actually touching the aluminum,” says Beaune. “It can be really good for beer. Cans heat up and cool down very quickly, too, so you obviously want to keep them cold.”

10. BEER IS MUCH SIMPLER THAN WINE.

You’ve got your four ingredients—malt, yeast, water and hops—what could be more basic than that? Manipulating those ingredients in various ways will give you different varieties, but breweries are doing some really cool stuff by adding flavors you’d never dream would work so well in beer. “A lot of the flavor in beer comes from the malt or the hops or yeast, but then there’s all of this freedom in beer,” says Beaune. “We did a beer at Allagash called Farm to Face, which is a pretty tart and sour beer. We added fresh peaches to it from a local farm. You can’t do that with wine—you can’t add peaches. People add everything you can imagine to beer like pineapple, coconut, every fruit—there are no rules. That’s one of the fun things about beer, it’s a lot like cooking, you can add rosemary, you can add whatever you want. Everybody experiments. It keeps the beer world really interesting.”

11. BEER WILL GIVE YOU A BEER BELLY, BUT COCKTAILS WON'T.

Sure, anything in excess will contribute to weight gain, but beer is hardly the most calorie-laden drink you’ll find in a bar. Much of the flack beer gets (i.e. the “beer belly”) goes back to the fallacy that beer is particularly heavy. “Most glasses of wine are pretty high in alcohol and a lot of cocktails are way higher in calories,” says Beaune. “If you drink a margarita that’s one of the highest calorie things you can drink.”

Spain's Famous Blue Wine Is Coming to America
Original image
Gïk

Last year, a Spanish startup caused a stir when it introduced its electric-blue wine to markets in Europe. Now, after receiving preorders for more than 30,000 bottles from American customers, the eye-catching beverage is finally ready to make its way to the U.S., Eater reports.

The bright blue drink, dubbed Gïk, is the creation of six young entrepreneurs with no previous experience in the winemaking industry. They collaborated with University of the Basque Country and the food research department of the Basque Government to make the product.

Gïk is made from a blend of red and white grapes with a non-calorie sweetener added in. Though the color resembles something you'd find in the cleaning supplies aisle, the ingredients that create the effect are all natural. A pigment found in grape skin and indigo from the Isatis tinctoria plant (commonly known as woad) are responsible for the wine's alarming hue.

The shade—which according to co-founder Aritz López represents "movement, innovation, fluidity, change, and infinity"—is intended to appeal to Millennial buyers. With an alcohol content percentage of 11.5, Gïk is comparable to a white zinfandel or prosecco, and a pack of three bottles retails for $48.

The Basque region of Spain is traditionally known for its sparkling, acidic wine, but Gïk was designed to stand out from the current options. In 2016, López told Eater that his team felt the Spanish wine scene was "missing a little revolution," so they set out to create something innovative. But it turned out to be a little too innovative for the company's own good: According to Spanish law, only red or white wine can be sold in local markets, and Gïk was fined €3000 (about $3600) for violating the rule. Following the controversy, they were forced to drop the "wine" label and start branding the concoction as "99% wine and 1% grape must."

Standards are less strict in the U.S., and when bottles reach markets stateside they will be flying under the wine banner once again. Gïk will make its U.S. debut in stores in Miami, Boston, and Texas before hopefully expanding to retailers in New York, New Jersey, Michigan, Washington, California, and Nevada. And while they may have the blue wine market cornered, there's at least one blue-hued beer brand out there Gïk will be competing with.
