A Brief History of Castoreum, the Beaver Butt Secretion Used as Flavoring

In September 2013, popular blogger “The Food Babe” released a video proclaiming that beavers “flavor a ton of foods at the grocery store with their little butthole!" Since then, the internet has been crowded with alarmist posts saying that beaver’s butts are used to flavor everything from soft drinks to vanilla ice cream. The culprit behind this scare is a flavorant called castoreum—but what exactly is it, and is it worth all the fuss?

WHAT IS CASTOREUM?

Castoreum is a substance secreted by male and female Alaskan, Canadian, and Siberian beavers from pouchlike sacs located near the base of their tails (castor is the word for beaver in Latin). Beavers can’t see or hear very well, but they have a great sense of smell—and as a result of their castoreum glands, they also smell great. They use their castoreum in part to mark their territory, secreting it on top of mounds of dirt they construct on the edges of their home turf. (The castoreum squirting out is apparently so loud, you can hear it if you’re standing nearby.) Beavers also use the fatty, waxy secretion to waterproof their fur.

An odorous combination of vanilla and raspberry with floral hints, castoreum carries information about a beaver’s health and helps to make distinctions between family members and outsiders. Beavers are so interested in the smell that historically, fur trappers would bait traps with castoreum.

HOW WAS IT USED?

When castoreum is fresh, it’s a fluid that ranges in color from yellow and milky to grey and sticky, depending on the type of beaver and its gender. In a live animal, this fluid is milked and dried to a solid for perfume making. In a dead animal, the entire castoreum gland is removed and, traditionally, preserved by smoking it over a wood fire.

For much of its history, castoreum was used as a medicine. Roman women inhaled the fumes of castoreum burned in lamps because they believed it would induce abortions (it didn’t). Hildegard von Bingen, a 12th-century Benedictine abbess, mystic, and scholar, wrote that powdered beaver “testicles” drunk in wine would reduce a fever; the castoreum gland, when dried, is easily mistaken for testes. Castoreum has also been used to treat headaches, which makes sense given that it contains salicylic acid, the main ingredient in aspirin.

The colonization of America led into an increase in the availability of beaver pelts, which were used to make fine hats all over Europe, and to a resurgence of interest in castoreum as medicine. Sold in drugstores and pharmacies, it was recommended for earaches, toothaches, colic, gout, inducing sleep, preventing sleep, and general strengthening of the brain. It was also in the 19th century that the substance began to be used in the perfume industry as a fixative—an ingredient that makes other scents smell better and last longer.

By the end of the 19th century, the demand for pelts and castoreum was so great that North American beavers were on the edges of extinction. In 1894, a representative of the Hudson Bay Company, a major beaver pelt and castoreum trading firm, said: "The beaver’s days are numbered. He cannot coexist with civilization.”

IS IT STILL BEING USED TODAY?

According to The Oxford Companion to Sugar and Sweets, castoreum was first used as a food additive in the early 20th century, but is now rarely, if ever, used in the mass-produced flavor industry. Nevertheless, the FDA considers it a “natural flavor,” since it is derived from a natural source, and can be used to add fruity strawberry or raspberry notes, or as substitute for vanilla (the compounds come from the beaver's diet of bark and leaves). One of the few places it's reliably found is the Swedish schnapps BVR HJT.

Beavers are generally no longer hunted for their pelts or castoreum, so to acquire the sticky stuff, beavers must be anesthetized and the castoreum gland milked by a human. The process was described as “pretty gross” by Joanne Crawford, a wildlife ecologist at Southern Illinois University who is no stranger to beaver butts; she noted that the goo has a consistency somewhat like molasses. Due to the inconvenience and expense of harvesting castoreum from live beavers, the substance is now seldom used. According to Fenaroli’s Handbook of Flavor Ingredients, the annual industry consumption is very low—around 300 pounds—whereas the consumption of natural vanillin is over 2.6 million pounds annually. When castoreum is used, it's far more likely to be in the profitable fragrance industry rather than in the foods we eat.

"In the flavor industry, you need tons and tons of material to work with," flavor chemist Gary Reineccius told NPR's The Salt. "It's not like you can grow fields of beavers to harvest. There aren't very many of them. So it ends up being a very expensive product—and not very popular with food companies."

So while it's hard to know what foods or fragrances contain castoreum, there is very little of it out there. It may be worth saving your alarm for another topic—or simply sparing a thought for the beaver.

The $13,000 Epiphany That Made Orville Redenbacher a National Popcorn King

Happy National Popcorn Day! While you’re no doubt celebrating with a bowl of freshly popped, liberally buttered popcorn, here’s something else to digest: Orville Redenbacher originally called his product Red-Bow.

In 1951, Redenbacher and his partner, a fellow Purdue grad named Charlie Bowman, purchased the George F. Chester and Son seed corn plant in Boone Township, Indiana. Though Redenbacher’s background was in agronomy and plant genetics, he had dabbled in popcorn, and was friendly with the Chester family.

Eventually, Carl Hartman was brought in to experiment. In 1969, when the trio had developed a seed they felt really confident in, they went to market. They dubbed the product “Red-Bow,” a nod to “Redenbacher” and “Bowman.”

The product was a hit regionally, but by 1970, Bowman and Redenbacher were ready for a national audience and hired a Chicago advertising agency to advise them on branding strategy. At their first meeting, Redenbacher talked about popcorn for three hours. “Come back next week and we’ll have something for you,” he was told afterward.

The following week, he turned to the agency and was told that “Orville Redenbacher’s” was the perfect name for the fledgling popcorn brand. “Golly, no,” he said. “Redenbacher is such a ... funny name.” That was the point, they told him, and they must have made a convincing case for it, because Orville Redenbacher is the brand we know today—and the man himself is still a well-known spokesman more than 20 years after his death.

Still, Redenbacher wasn’t sure that the $13,000 fee the agency had charged was money well spent. “I drove back to Indiana wryly thinking we had paid $13,000 for someone to come up with the same name my mother had come up with when I was born,” Redenbacher later wrote.

11 Secrets of Restaurant Servers

If you enjoy eating at restaurants, it's worth getting to know the waitstaff. Servers are the face of the establishments where they work, and often the last people to handle your food before it reaches your table.

"People think it’s an easy job, and it’s really not," Alexis, a server who’s worked in the business for 30 years, tells Mental Floss. She says, jokingly, "You want a professional handling your food, because we have your life in our hands."

Even if they don't spit on your plate (which thankfully they almost never will), a waiter can shape your dining experience. We spoke with some seasoned professionals about how they deal with rude customers, what they wish more customers would do, and other secrets of the job.

1. Server pay varies greatly.

The minimum wage changes from state to state, but for tipped workers like servers, the difference in pay can be even more drastic depending on where you work. In over a dozen states, if a worker typically makes a certain amount per month in tips (often $20-$30), their employers are only required to pay them a minimum of $2.13 an hour. That’s how much Jeff, a video producer who’s held various jobs in the restaurant industry, made when serving tables in New Jersey. “Usually, if I had a full paycheck of serving I could just put a little bit of gas into the tank,” he tells Mental Floss.

Waiters and waitresses in many states rely almost entirely on tips to make a living—but that’s not the case everywhere. California, Oregon, and Washington each pay tipped employees minimum hourly wages over $10. Jon, who currently works at a casual fine dining restaurant in Portland, Oregon, gets $12 an hour from his employer. Including tips, he typically earns $230 a day before taxes, and brings home about $34,000 a year on a 25-hour work week.

2. They split up tips among the restaurant staff.

Here’s another reason to be generous with your tips: Whatever extra money you leave on the table may be going to more than one person. If you ordered a drink from the bar, or if there was anyone other than your server bringing your food and clearing it from the table, that tip will likely be split up. At one restaurant job, Jeff says he paid food expeditors (workers who run food from the kitchen to tables) 10 percent of whatever tips he earned.

3. Waiters and waitresses know how to handle rude customers.

In addition to taking orders and serving food, servers are often forced to de-escalate conflicts. For many people waiting tables, this means acting sweet and professional no matter how angry customers get. Jon’s strategy is to “treat them like a child, smile, tell them everything they want to hear and remind yourself that it’ll be over soon.” Similarly, Mike (not his real name), a server at a farm-to-table restaurant in Texas, likes to “kill them with kindness." He tells Mental Floss he tries to “be the bigger man and [not] return sour attitudes back to people who don’t treat me with respect. If nothing else I can hold my head high knowing I did my job to the best of my ability and didn’t let their negativity affect my day with other, more pleasant patrons.”

Alexis, who currently waits tables at a family-owned restaurant in California, goes beyond faking a smile and makes a point to practice empathy when serving rude guests. “There’s a hospital near my restaurant, and people come there for comfort food with hospital visitor stickers on their clothes all the time. And I know then that they’re going through something traumatic usually. So when people are acting badly, I put imaginary hospital stickers on their clothes and try to remove my ego.”

4. Your waiter (probably) won’t spit in your food.

While most servers have had to deal with a customer who treats them poorly, they rarely retaliate. On the old urban legend of servers spitting in their customer’s food, Alexis says, “Never seen anybody mess with anybody’s food out of spite or malicious intent. I’ve never seen it happen and I’ve never actually done it. I don’t need to get back at people like that.”

5. Servers do more than wait tables.

Most customers just see one aspect of a server's jobs. When they’re not refilling your drinks and bringing you condiments, they're doing side work—either before the restaurant opens, after the last guest leaves, or in between waiting tables. “It could be rolling silverware, filling sauces, cutting lemons, rotating salad bars, stuff like that,” Jeff says. “It’s not just serving and you leave; there’s usually something else behind the scenes that the server has to do.”

Alexis says that in addition to hosting and serving, she has to prep to-go orders, bus tables, and wash dishes. "We’re expected to be working every moment,” she says.

6. Waiters have some wild stories.

Though parts of the job are tedious, servers are bound to see interesting things. Alexis recalls a husband and wife who were regulars at the restaurant where she worked in the 1990s; the man was later arrested for murder. “I found out when a newspaper reporter started asking me questions about them,” she says. “I’m quoted on the front page of the LA Times as saying ‘A waitress in a local coffee shop said they were a nightmare!’”

Other stories are lighter. “When I worked at Red Robin there was a lady that came in every morning and would ask to sit in the same booth," Jon says. "She carried a bag [of] stuffed animals (mostly dragons) and situated them around the booth, always in the same spots, she’d talk to them throughout her dining experience.”

7. Waiters hate it when you don't know what you want.

The simplest way to get on your server’s good side is to know exactly what you want when you tell them you're ready to order. That means not wasting their time stalling as you speed-read the menu. If you haven't decided on a dish, let your server know and trust that they'll return to your table in a few minutes. “Don’t tell your server you’re ready to order if you’re not ready to order,” Alexis says. “I’m like ‘Come on, I know you’re not ready. I’m going someplace else and I’ll be back.’”

It also means not asking your server to make several trips to your table in the span of a few minutes. Mike says that customers asking for items one at a time is one of his biggest pet peeves. “[Customers will say] ‘I need salt. I need hot sauce. I need another [...] drink.’ I was away from the table for 30 seconds each time. Those requests could easily be fulfilled in one trip to the kitchen.”

8. Waiters hate when you ask to move tables.

Next time you get seated in a restaurant, think twice before asking your server to switch tables. Restaurants divide their floor plan into sections, and each server is responsible for a different group of tables. The hosts in charge of seating rotate these sections to distribute guests evenly to servers; by asking to move, you may be depriving one server of an hour’s worth of tips while creating extra work for a server who’s already swamped. According Jon, the worst time to complain about where you were seated is when a restaurant is busy: “Sometimes this isn’t a problem if we’re slow, but if it’s a Friday/Saturday chances are you were put there for a reason.”

9. Servers work when everyone else gets the day off.

Servers have to be prepared to work a different schedule every week, work late into the night, and work on weekends. This can make maintaining a normal social life challenging. “My schedule can be troublesome, my girlfriend/friends have the opposite schedule as me so I’m never able to make it out on weekends or holidays,” Jon says.

And on the days many 9-to-5 workers go out to celebrate, servers have to wait on them. “Where I currently work I have worked Christmas Eve, Christmas, New Years Eve, New Years Day, and I will have to work on Mardi Gras (in the South),” Mike says. “I was leaving for work as my family arrived at my house for Christmas. I missed a New Years party in my house. If I hadn’t requested if off as soon as I began working there I’m almost certain I’d have to work 15 [hours] on my birthday.”

10. Your server might give you a free drink if you order it at the right time.

Asking your server for a free stuff likely won’t get you anywhere, but there is one thing you can do to possibly have a drink taken off your bill. If you wait until after your meal is served to order something cheap like a soft drink, Alexis says there’s a chance you won’t get charged for it all. “Not alcoholic drinks, but I’m talking about a cup of coffee or a soda or something like that, especially if you’re already paying for other beverages,” she says. “The server might get too busy or might not be inclined to go back to the POS [point of sale] system and add them on to your bill. It’s more trouble than it’s worth sometimes.”

11. Waiters want you to learn their names.

There’s a reason most servers introduce themselves before taking your order: They’d much rather you use their real names than a demeaning nickname. “Don’t call me sweetheart! I’m wearing a damn name tag,” Alexis says. “Sometimes I respond well, and other times no.”

And if your server doesn’t introduce themselves and isn’t wearing a name tag, Jon says it doesn’t hurt to ask. “Ask what the servers name is and refer them by name when you’re talking to them.” He says it’s “refreshing when a guest does this.”
