Coffee brewing is in the midst of a revolution, and I'm not talking about the AeroPress. It comes in the form of a small 2-by-2-inch single-serving pod that requires a special machine. Keurig, owned by Vermont-based Green Mountain Coffee, makes the most popular pods, called "K-Cups." At the press of a button, the Keurig brewer punctures a small hole into the aluminum lid of an individual plastic cup filled with grounds, flushes it with steaming water, and, voilà! Out comes one hot cup of joe.
When Keurig launched its specialized brewing system in 1998, it might have come off as a bit niche. Not anymore. According to a survey by the National Coffee Association, nearly 1 in 5 adults drank single-cup-brewed coffee yesterday, making it the second most popular way to brew after the traditional drip methods—and far more popular than espresso machines.
Keurig would not tell me what types of plastic go into its #7 blend, saying the information was proprietary.
The single-serve method has experienced impressive growth: According to the Seattle Times, while US consumers bought $132 million worth of coffee pods in 2008, they forked over $3.1 billion for them last year, compared to $6 billion for roasted coffee and $2.5 billion in instant coffee. Keurig also has similar brewing systems and pods for tea and iced beverages, and will roll out a system for Campbell's soup later this year.
What Keurig customers love, proclaims Green Mountain's 2013 annual report, is the system's "Quality, Convenience, and Choice"—and let's be real, it's convenience that trumps for most busy Americans. Keurig systems take under a minute to brew coffee, and cleaning them is laughably easy: Just chuck the used coffee pod in the trash, then press a button, and a "cleansing brew" shoots hot water through the system to clear it of residue.
But critics warn that the packaging needed for these systems comes with environmental and health-related costs. By making each pod so individualized, and so easy to dispose of, you must also exponentially increase the packaging—packaging that ultimately ends up in landfills. (And that's to say nothing of the plastic and metal brewing systems, which if broken, aren't that easy to recycle either.)
Journalist Murray Carpenter estimates in his new book, Caffeinated, that a row of all the K-Cups produced in 2011 would circle the globe more than six times. To update that analogy: In 2013, Green Mountain produced 8.3 billion K-Cups, enough to wrap around the equator 10.5 times. If Green Mountain aims to have "a Keurig System on every counter," as the company states in its latest annual report, that's a hell of a lot of little cups.
Green Mountain only makes 5 percent of its current cups out of recyclable plastic. The rest of them are made up of a #7 composite plastic, which is nonrecyclable in most places. And for the small few that are recyclable, the aluminum lid must be separated from the cup, which also must be emptied of its wet grounds, for the materials to make it through the recycling process. Even then, chances are the pod won't be recycled because it's too small, says Darby Hoover, senior resource specialist at the Natural Resources Defense Council.
Keurig just released a sustainability report announcing that the company plans to make all coffee pods recyclable by 2020, among other ecofriendly efforts. The company says it's evaluating the type of plastic used in the cups, exploring potential biodegradable and compostable packaging, and coming up with an easier way for customers to easily prepare them for recycling.
Some competitors already have recyclable or biodegradable versions of this single-serve pod; Nespresso's lid and pod is made entirely from aluminum. A Canadian brand, Canterbury Coffee, makes a version that it says is 92 percent biodegradable (everything save for the nylon filter can break down). Finding a substitute is an interesting challenge, says Keurig spokeswoman Sandy Yusen, because coffee is perishable, and so the material used must prevent light, oxygen, and moisture from degrading the coffee.
Another reason to look beyond plastic is a concern with what could leach out of the material when heated. Yusen confirmed that the #7 plastic used in K-Cups is BPA-free, safe, and "meets or exceeds applicable FDA standards." But new evidence suggests that even non-BPA plastics can test positive for estrogenic activity. (Our "Frightening Field Guide to Common Plastics" contains more information about this.)
"No. 7 plastic means 'other,'" says the NRDC's Hoover. "You don't know what it is." One concern with this plastic mix is the presence of polystyrene, containing the chemical styrene, which Hoover warns is especially worrisome for workers. A possible carcinogen, styrene can wreak havoc on the nervous systems of those handling it, according to the Centers for Disease Control and Prevention. The chemical also shows up in tobacco smoke and home copy machines, and in the Styrofoam used in food containers.
The New York Times determined that single-brew coffee ends up costing more than $50 a pound, even for Folgers.
Keurig would not tell me what types of plastic go into its #7 blend, saying the information was proprietary, nor would it confirm or deny the presence of polystyrene in the mix.
Keurig does make a plastic and mesh reusable coffee filter. But why use a filter that necessitates cleaning—and also requires a fancy-schmancy brewing system—over the traditional method? As Hoover points out, "you're essentially giving up the convenience of the little teeny tiny cup."
It's not just convenience that's sacrificed. By my calculations, a K-Cup-worth of coffee will run up your tab way more than grounds and a filter (not including the cost of the brewer); a standard pod of Green Mountain coffee costs 68 cents, while one cup of the company's Vermont Blend brewed the traditional way costs about 44 cents, filter included. The New York Times did a more comprehensive analysis of the actual price of single-brew coffee, and determined that it ends up costing more than $50 a pound, even for standard brands like Folgers, compared to the less than $20 you can expect to pay for a bag of roasted beans. Call me a cheapskate, but I'll stick to freshly ground coffee that doesn't require a bulky brewer and billions of plastic pods to be delicious.
But despite its pervasiveness, we still understand little about the stuff. It doesn't help that the beverage industry hopes to keep it that way; for instance, though energy drink sales have skyrocketed in recent years, their manufacturers aren't required to label how much caffeine their products contain. Meanwhile, emergency room visits related to energy drink use increased more than tenfold between 2005 to 2009.
In his new book, Caffeinated: How Our Daily Habit Helps Us, Hurts, and Hooks Us, out March 13, journalist Murray Carpenter takes on this mysterious substance. He toured Colombian coffee fields, Chinese tea lounges, and factories pumping out synthetic caffeine for soft drinks, interviewing FDA regulators, industry spokesmen, neuroscientists, and cacao cultivators. I chatted with Carpenter about how much caffeine is healthy, where the industry stands on labeling, and the most pretentious coffee preparation he's observed. Here were some of the biggest takeaways.

1. A healthy daily dose of caffeine can be very different depending on who you are.
"When doctors talk about moderate caffeine use, they talk about somewhere in the range of 300 to 400 milligrams. Most coffee drinkers tend to be in that range. Beyond that: 300 milligrams to one person might be perfect, but it might send another one through the roof. It varies so much, depending on your size, if you're a smoker, if you have a genetic predisposition to metabolize caffeine slowly. It would be foolish to say X is the perfect amount or X is too much.
"Women on birth control metabolize caffeine twice as slowly—which means they get double the jolt from the same cup of coffee. And smokers metabolize it twice as fast. There are some people with a genetic predisposition to metabolize caffeine slowly. Those are the people who are going to be super sensitive to caffeine."
2. There's no standard amount of caffeine in each cup of coffee—even within the same brand.
"Starbucks gives an approximation of 20 milligrams per ounce. One 16-ounce cup of Starbucks puts you at about 320 milligrams of caffeine. One 16-ounce cup of Starbucks is for many Americans a good daily dose of caffeine.
As the world gears up for the Sochi Games, we reached out to these three amazing women to talk about everything from their first runs to high-speed crashes to race and gender politics. The opening ceremonies take place on Friday, February 7. Here's the complete schedule of events.
Jazmine Fenlator, 28, bobsled
A lot of people think I'm on the Jamaican bobsled team. It's a question every black bobsledder gets, even if you're wearing a USA shirt. My dad used to love watching Cool Runnings with me. When I told him I got an invite to try out for the US bobsled team, his first words were: "Sanka! You dead, mon? Let me kiss your lucky egg!" Growing up biracial, I never really thought about things: I mean, you have some acceptance issues, but I grew up in a predominately white town. The side of my family I'm closest with is all white, so it's not necessarily a topic of conversation. You get a lot of naive questions, but I welcome those. The more people I can teach and tell about bobsled, the more cheers we'll have in Sochi. Not many people can relate to bobsled, and it's hard to spectate. It's a grueling, blue-collar sport. To support my bobsled habit, I've sometimes worked three jobs in the offseason. We do all the work on our sleds. We carry our sleds. There's no caddy, there's no pit crew. We handle all those things on top of trying to be the best athletes within our sport in the world.

Katie Uhlaender, 29, skeleton
I always challenged men in foot races or whatever as a kid growing up, because it was a way of challenging myself—but you have to accept that men are born with testosterone. You can beat them for so long, but eventually they're gonna catch up. There is a double standard: My father was a major league baseball player, and I grew up thinking I could have the same attitude on the field that he did. When I did that in real life, people thought I was a total bi-atch. [Laughs.] Women are held to a different standard, but there's a reason. Because we are mothers, we have a different role in society. There are certain benefits we get being women—and we deserve them! But don't take advantage of them. You have to walk the line and show that you have self-worth. If you lose yourself, then no one's going to respect you. Miley Cyrus, the girl crossed the line! You can be sexy without licking a hammer.

Maddie Bowman, 20, halfpipe freeskiing
Some people don't understand that you can ski in the halfpipe. They think it's cool and kinda crazy. It's like a polar bear-grizzly bear mix—a pizzly. It's a new species and it's super badass! I was a racer before, but it felt a little too serious. My parents were a little resistant, but then they skied with us and realized we think about things before we jump off of stuff. They definitely get nervous. You can't have my mom video a run at all because it's so shaky—she always misses it! The first time I ever did a "left nine"—it's two and a half spins, and I'm spinning down the wall, rotating to the left—I was so excited I completely forgot the rest of my run; I just sort of made it up. Most skiers, we can think pretty quickly on our feet—or off our feet if we're falling. We like to push the limits, but when the limits push back, it's always a rude awakening. Concussions and injuries are something everyone worries about. But you can't be out there worrying about getting hurt, or else you're more likely to get hurt. If I got hurt, knock on wood, I don't know what I would do. Maybe I'd actually be a real college student.

And in a Facebook post, the organization linked to a Washington Post list of "Seven American Women Who Made a Difference in 2013," including US Health Secretary Kathleen Sebelius. These links were enough to spur John Pisciotta, who runs Pro-Life Waco, to launch a national boycott. "The Girl Scouts were once a truly amazing organization, but it has been taken over by idealogues of the left, and regular folk just won't stand for it," Pisciotta told Breitbart News. Fox News anchor Megyn Kelly also took up the cause with a full-on panel on the offending tweet.
Ultimately, though, the campaign is about more than a couple of social-media postings: On its website, the "CookieCott 2014" campaign argues that the boycott is a protest of the Girl Scouts' "deep and lasting entanglement with abortion providers and abortion rights organizations." This includes, it claims, promoting role models like Gloria Steinem, Betty Friedan, Hillary Clinton, Amnesty International, ACLU, and the National Organization for Women, and supporting "youth reproductive/abortion and sexual rights" via its membership in the World Association of Girl Guides and Girl Scouts.
The bullying seems to have worked: In a blog post Wednesday, Girl Scouts offered "our sincerest apologies," noting, "To be clear, Girl Scouts has not endorsed any person or organization." Is that sort of meekness consistent with the organization's quest to "build girls of courage, confidence, and character"? Ponder that while you try to resist those Samoas.
Jehane Noujaim's The Square, which won an audience award at the 2013 Sundance Film Festival and is on the shortlist for an Oscar this year, delivers a fierce and frenetic portrait of life on the Cairo streets during two years of Egypt's ongoing political unrest. Based on more than 1,600 hours of footage, the film tags along with several revolutionaries—among them Ahmed, a fiery grassroots activist, Magdy, a member of the Muslim Brotherhood, and Khalid, a foreign-born actor—as they struggle against a suffocating regime and attempt to breathe new life into Egypt's governance.
The Square made headlines when it became Netflix's first major film acquisition—it will stream exclusively through the service starting January 17—and also because its only scheduled public screening in Egypt was canceled at the last minute. The country's censorship board still hasn't give Noujaim, whose past work includes Control Room and Rafea: Solar Mama, permission to screen the film in public.
The doc's narrative arc initially hinged on the deposition of Hosni Mubarak and subsequent election of Mohamed Morsi as president. But history is often messier than we would wish to tell it. In January 2013, as Noujaim scrambled to meet her Sundance deadlines, she learned that her main characters "were back in the streets again saying, 'Morsi is using the tools of democracy to create another dictatorship.'" The story wasn't over.
