10 Things You Might Not Know About Wine

Between the vine and the liquor store, plenty of secrets are submerged in your favorite bottle of wine. Here, Tilar J. Mazzeo, author of Back Lane Wineries of Sonoma, spills some of the best. Here are a few things you might not know about wine.

1. Digital eyes are everywhere in today's vineyards.

Certain premium estates in Bordeaux and Napa are beginning to look a little more like army bases—or an Amazon.com warehouse. They’re using drones, optical scanners, and heat-sensing satellites to keep a digital eye on things. Some airborne drones collect data that helps winemakers decide on the optimal time to harvest and evaluate where they can use less fertilizer. Others rove through the vineyard rows, where they may soon be able to take over pruning. Of course, these are major investments. 

2. Modern vineyards also bury a lot of cow skulls. 

They’re not everywhere, but biodynamic farming techniques are on the rise among vintners who don’t want to rely on chemicals, and this is one trick they’ve been known to use to combat plant diseases and improve soil PH. It’s called Preparation No. 505, and it involves taking a cow’s skull (or a sheep’s or a goat’s), stuffing it with finely ground oak chips, and burying it in a wet spot for a season or two before adding it to the vineyard compost.

3. Ferocious foliage is a vintner's secret weapon.

The mustard flowers blooming between vineyard rows aren’t just for romance. Glucosinolates in plants like radishes and mustard give them their spicy bite, and through the wonders of organic chemistry, those glucosinolates also double as powerful pesticides. Winemakers use them to combat nematodes—tiny worms that can destroy grape crops.

4. Roses in a vineyard are the wine country equivalent to the canary in the coal mine. 

Vintners plant roses among their vines because the flowers get sick before anything else in the field. If there’s mildew in the air, it will infect the roses first and give a winemaker a heads-up that it’s time to spray.

5. Birds of prey help protect the grapes.

Small birds like blackbirds and starlings can clear out 20 percent of a crop in no time. But you know what eats little birds? Big birds. Falconry programs are on the rise in vineyards from California to New Zealand. Researchers have found that raptors eat a bird or two a day (along with a proportion of field mice and other critters) and cost only about as much to maintain as your average house cat.

6. Small bugs become big problems in wine tasting rooms.

Winemakers are constantly seeking ways to manage the swarms of Drosophila melanogaster that routinely gather around the dump buckets in their swanky showrooms. You know these pests as fruit flies, and some vintners in California are exploring ways to use carnivorous plants to tackle the problem without pesticides. Butterworts, sundews, and pitcher plants all have sweet-sounding names, but the bug-eating predators are fruit fly assassins, and you’ll see them decorating tasting rooms across wine country.

7. Wine needs to be filtered. 

Winemaking produces hard-to-remove sediments. Filters can catch most of the debris, but winemakers must add “fining agents” to remove any suspended solids that sneak by. (Unwanted compounds in the wine bind with the fining agents so they can be filtered and removed.) Until it was banned in the 1990s, many European vintners used powdered ox blood to clean their wines. Today, they use diatomaceous earth (the fossilized remains of hard-shelled algae), Isinglass (a collagen made from fish swim bladders), and sometimes bentonite (volcanic clay). Irish moss and egg whites are also fine wine cleaners.

8. Wine is ever so slightly radioactive (that's a good thing).

About 5 percent of the premium wine sold for cellaring doesn’t contain what the label promises. So how do top-shelf buyers avoid plunking down serious cash on a bottle of something bunk? Most elite wine brokerages, auction houses, and collectors use atomic dating to detect fraud. By measuring trace radioactive carbon in the wine, most bottles can be dated to within a year or two of the vintage.

9. MRIs can determine the fine from the funk.

Even with atomic dating, there are certain perils involved in buying a $20,000 bottle of wine. Leaving a case in the hot trunk of your car is enough to ruin it, so imagine what can happen over a couple of decades if a wine isn’t kept in the proper conditions. Back in 2002, a chemistry professor at University of California at Davis patented a technique that uses MRI technology to diagnose the condition of vintage wines. This technique may soon be used at airport security, meaning you’ll be able to carry on your booze.

10. Wines can be aged instantly.

If you end up with a bottle of plonk, Chinese scientists have developed a handy solution. Zapping a young wine with electricity makes it taste like something you’ve cellar aged. Scientists aren’t quite sure how it happens yet, but it seems that running your wine for precisely three minutes through an electric field changes the esters, proteins, and aldehydes and can “age” a wine instantly.

Indoor heaters not only provide a boost of heat for drafty spaces, but they can also be a money-saver, allowing you to actively control the heat based on the rooms you’re using. Outdoor heaters, meanwhile, can help you take advantage of cold-weather activities like camping or tailgating without having to call it quits because your extremities have gone numb. Check out this list of some of Amazon’s highest-rated indoor and outdoor heaters so you can spend less time shivering this winter and more time enjoying what the season has to offer.

6 Punctuation Marks Hated by Famous Authors

Punctuation marks are not the most important tools in a writer's toolkit, but writers can develop some strong opinions about them. Here are six punctuation marks that famous authors grew to hate.

1. The Oxford Comma

The Oxford comma, also known as the serial comma, inspires passionate emotions on both sides, but more frequently on the pro side. James Thurber, a writer for The New Yorker and author of The Secret Life of Walter Mitty, made a case against the Oxford comma to his editor Harold Ross, in a discussion of the phrase “the red, white, and blue.” Thurber complained that “all those commas make the flag seemed rained on. They give it a furled look. Leave them out, and Old Glory is flung to the breeze, as it should be.”

2. The Comma

Gertrude Stein had no use for the Oxford comma, or any kind of comma at all, finding the use of them “degrading.” In her Lectures in America, she said, “Commas are servile and they have no life of their own … A comma by helping you along and holding your coat for you and putting on your shoes keeps you from living your life as actively as you should lead it.”

3. The Question Mark

The comma wasn't the only piece of punctuation Stein took issue with; she also objected to the question mark [PDF], finding it “positively revolting” and of all the punctuation marks “the completely most uninteresting.” There was no reason for it since “a question is a question, anybody can know that a question is a question and so why add to it the question mark when it is already there when the question is already there in the writing.”

4. The Exclamation Point

In Beloved Infidel, Sheilah Graham’s memoir of her time with F. Scott Fitzgerald in his later years, she describes the things she learned from him about life and writing. In a red-pen critique of a script she had written, he told her to “Cut out all these exclamation points. An exclamation point is like laughing at your own joke.”

5. The Apostrophe

Playwright George Bernard Shaw thought apostrophes were unnecessary and declined to use them in words like don’t, doesn’t, I’ve, that’s, and weren’t. He did use them for words like I’ll and he’ll, where the apostrophe-less version might have caused confusion. He made clear his disdain for the little marks in his Notes on the Clarendon Press Rules for Compositors and Readers, where he said, “There is not the faintest reason for persisting in the ugly and silly trick of peppering pages with these uncouth bacilli.”

6. The Semicolon

Kurt Vonnegut, in his essay “Here Is a Lesson in Creative Writing” (published in the book A Man Without a Country), comes out forcefully against the semicolon in his first rule: “Never use semicolons.” He insults them as representing “absolutely nothing” and claims “all they do is show you’ve been to college.” Semicolon lovers can take heart in the fact that he may have been kidding a little bit—after using a semicolon later in the book, Vonnegut noted, “Rules take us only so far. Even good rules.”
