The United Kingdom loves its tea. But if Oliver Cromwell's head hadn't ended up on a spike
0:05
coffee might have remained the country's most prevalent pick-me-up. And while countless
0:10
half-completed screenplays have been penned in the world's 30,000-plus Starbucks locations, cafe culture might not have spread throughout the globe if Islam permitted its adherents
0:19
to imbibe alcohol. Collectively, coffee and tea have been credited as catalysts for everything
0:24
from the Enlightenment to the Opium Wars. Tracing the fascinating history of these
0:29
caffeinated beverages, touches on brain chemistry, the emergence of global capitalism, and deep-seated
0:35
cultural beliefs, both edifying and destructive. But it's none of my business
0:44
Wait, no, that actually is my business, what this whole video is about. You know what? Let's just
0:48
get started. Hi, I'm Justin Dodd. Welcome to Food History. The origins of both tea and
0:59
coffee have been mythologized. According to a Chinese legend, tea was discovered by Emperor
1:04
Shenang around the year 2732 BCE. As the story goes, the emperor was boiling water beneath the
1:10
tree when the wind blew some leaves into his pot. The plant infused into the liquid, and when he
1:16
sipped it, he was filled with a pleasant, energizing sensation. The tree from the story
1:20
was Camellia sinensis, a plant native to the borderlands of north Myanmar and southwest China
1:25
All true teas come from this plant, which is why herbal teas like chamomile should technically be
1:30
referred to as infusions or tazans. Coffee doesn't come from leaves, and it technically
1:35
doesn't come from beans either. The source of all things coffee is the fruit that grows on the
1:40
tropical kaffia plant. These so-called coffee cherries are small and red with a hard stone-like
1:46
core. The bean we use to brew the beverage is actually the fruit seed. There are usually two
1:51
inside each cherry. Legend attributes the adoption of coffee into human diets to a goat herder
1:56
named Chaldee around 850 CE. Sometimes the story is said to take place in what is today Ethiopia
2:03
other times Yemen. The gist of it is that Chaldee's goats started dancing one day after nibbling
2:07
berries from a kaffee-ish rub. Chaldee tried the fruit for himself and experienced the plant's
2:12
stimulating effects. Thrilled about his discovery, he brought the coffee cherries to a nearby
2:16
monastery or mosque. The people there didn't share his excitement. After calling the fruit
2:22
the Devil's work, they tossed the berries into the fire. As the coffee beans roasted, the skeptics were intoxicated by the scent and regretted
2:29
their decision. They crushed the beans by stomping out the flames and added the grounds
2:34
to hot water to preserve them, thus brewing the world's first pot of coffee. After giving
2:38
it a try, they decided that the drink's ability to keep them awake for hours of prayer canceled
2:43
out any satanic properties it may have had. It's a charming story, but no version of it has ever been verified by historians
2:50
When coffee writer Ken Davids performed an unscientific experiment to gauge Yemeni goats
2:55
interest in coffee cherries, he found they preferred dried grass in the leaves of the
2:59
local cat tree. Davids did note that he later saw goats in Ethiopia happily eating coffee tree leaves
3:05
but the lack of contemporary accounts of Chaldi's exploits cast the story into some serious doubt
3:10
Still, the myth, if it is a myth, points to a real part of coffee's history
3:15
Caffea arabica, the most popular species of the plant, probably did originate in the plateaus of Ethiopia, where it continues to grow in the wild today
3:23
The other most popular species of coffee is Caffea canifora, often called Robusta
3:28
It's cheaper to produce and contains significantly more caffeine than arabica. That high caffeine level might actually help ward off pests
3:35
For many years, the Western coffee world has considered Robusta an inferior product
3:40
which is why you're much more likely to see a higher-end coffee bag brag about containing 100
3:45
Arabica beans. Industry opinions may be evolving, though, as more professionals come to recognize
3:50
the two species as distinct, but not necessarily better or worse. Robusta, for its part, has long been enjoyed in some of the countries in which it's grown
3:57
like Indonesia and Vietnam, where its tendency to taste more bitter might have helped give rise to
4:02
delicious iced coffee drinks sweetened with condensed milk called Cafe Surada. Making coffee
4:08
on a large scale is complicated by the quirks of the Kaffia plant. It ripens unevenly, and
4:13
the Arabica plant especially grows on steep terrain, so harvesting coffee cherries at
4:18
peak ripeness often has to be done by hand. That's why it's not unusual for coffee
4:23
farmers supplying some of the world's largest corporations to earn less than $3 a day
4:28
To stay competitive these farmers often have to sell their coffee cherries at a price that doesn match the labor required to cultivate them It a bit beyond our historical lens to fully dive into this topic but if you interested you should definitely look into how your coffee is sourced and how the farmers are
4:43
compensated. Because much of the product's value has historically been seen as arising later in the
4:48
production process, those farmers often don't have much leverage to negotiate with. Once coffee
4:53
cherries are harvested, they get processed and dried to remove excess moisture. At some point
4:58
It varies depending on the processing technique being employed. The fruit is removed
5:03
Then the beans get roasted. Somewhere around 400 degrees Fahrenheit, they start releasing an oil called caffiol
5:09
which is partly responsible for the rich taste and fragrance we associate with coffee
5:13
Coffee also develops its deep brown color during the roasting process. Roasted beans are ready to be ground
5:19
and ground beans are ready to be brewed into a cup of coffee, or espresso, or a pumpkin spice latte, or whatever your preferred coffee beverage is
5:27
Green tea, white tea, oolong, and black tea all come from the leaves of the same tea plant
5:33
Camellia sinensis, but the way those leaves are prepared can create distinct beverages
5:38
The leaves that become black tea are crushed before they're dried, which exposes the chemicals in their cells to increased levels of oxygen
5:44
During oxidation, the chlorophyll that makes plants green degrades into pheophytans and
5:49
pheophorbides, which gives tea leaves a black or brown appearance. Other compounds like lipids
5:53
amino acids, and carotenoids break down as well, changing the flavor profile of the plant
5:58
Tea manufacturers know when to stop the oxidation process to achieve the flavor
6:03
and aroma they want for their product. To make green tea, they stop oxidation early. Oolong is
6:09
semi-oxidized, and black tea is considered fully oxidized, which gives it its bold flavor
6:14
White tea is made from young Camellia sinensis leaves that haven't fully opened, and they're
6:18
oxidized the least of the four main varieties you're likely to encounter at the local market
6:23
Given their proximity, it may not have taken long for coffee to get from Ethiopia to Yemen
6:28
Like the monks from the legend, Sufis in Yemen really did use coffee to get through
6:31
nighttime prayers and devotions. The beverage quickly spread throughout the Muslim world
6:36
It played a social role as well as a spiritual one when coffeehouses emerged in the Islamic world
6:41
during the 16th century. These businesses became community hubs where men from all levels of
6:46
society could come together and discuss important topics. In a culture where alcohol was banned
6:51
coffee houses function as community taverns. The drink was even called kaveh, which is sometimes
6:56
said to be an Arabic word for wine. Like coffee, tea was seen as something sacred
7:01
following its discovery in China. Buddhist monks were drawn to it for the same reason
7:05
that Sufis drank coffee. It kept the mind clear and alert for extended meditation sessions
7:10
Just the process of pouring water and brewing tea became a spiritual, meditative act for followers
7:16
of Buddhism. Both coffee and tea have caffeine, to thank for their popularity with religious types
7:21
and anyone else who's ever needed a pick-me-up. The natural stimulant is found in both the
7:25
coffea plant and camellia sinensis, and thanks to coffee and tea's global success, it's the most
7:30
widely consumed drug on Earth. Though it feels like it wakes you up, it would be more accurate
7:35
to say that caffeine stops you from getting sleepy. The chemical is similar in size and
7:40
shape to an inhibitory neurotransmitter called adenosine. Throughout the day, adenosine builds
7:45
up in the brain and makes you feel tired. When you drink coffee or tea, caffeine settles into
7:50
the receptors shaped to fit adenosine, which blocks the neurotransmitter from getting in
7:54
and bringing down your energy. A standard 8-ounce cup of coffee contains around 95mg of caffeine
8:00
which is more than double the 47mg of caffeine in an average cup of black tea. That could be a mark
8:06
against coffee if you're afraid of headaches or jitteriness, or it could be a plus if your main
8:10
concern is getting through the first hour of work without falling asleep at your desk
8:14
The word tea comes from the Chinese word tu, which means bitter vegetable. Tu also gives us
8:19
thus the Mandarin word cha, which first appeared in print circa 760 CE when a Chinese scholar left
8:25
out a cross-stroke when writing out the character for tea. Today, the word for the drink used in
8:30
almost every language derives from one of these two terms. In general, whether a Western country
8:35
says it drinks tea or cha today depends on whether it traded with China by sea or land
8:40
centuries ago. The Dutch East India Company imported its tea from an area of China where
8:45
they called it something like Tay. From there, it traveled to Western European countries like
8:50
France, England, and Germany. But not Portugal. They had their own trading links with China in a
8:55
region where people said Cha. That's what the Portuguese call the drink to this day
8:59
Central Asia also picked up Cha According to University of Pennsylvania professor Victor H Mayer it seems that Cha got adopted by the Mongol Empire which used Persian as a common language In Persian chai got an alternate form chai which spread throughout much of Asia
9:15
Today, chai and tea are two words for the same beverage, so when you ask your barista for a chai
9:20
tea, you're technically repeating yourself. The spice drink you're looking for actually
9:25
corresponds pretty closely to a beverage called masala chai in India. Coffee had some hurdles to overcome before it would be embraced in Europe
9:32
Because it was viewed as a Muslim product, xenophobic Christians branded it as the
9:37
bitter invention of Satan. Catholics called upon Pope Clement VIII to condemn it officially
9:42
but he was said to have had a surprising reaction when he took his first sip. He reportedly called the devil's drink delicious and proposed cheating the devil by baptizing the
9:50
beverage. That story is almost certainly a myth, but it reflects real concerns about coffee
9:55
consumption at the time in Europe. Still, despite those misgivings, the drink's popularity skyrocketed
10:02
Unlike beer, which had been the continent's morning beverage of choice, coffee boosted energy levels
10:07
and sharpened the mind. Drinking coffee quickly became a social activity as well as a way to start
10:12
the day. The coffee houses that originated in the Ottoman Empire began popping up across Europe
10:17
By the mid-1600s, there were 300 such establishments in London alone. Much like today, coffee houses
10:24
were places where creative minds went to find inspiration. Some were known as penny universities
10:29
Establishments where patrons paid a penny for their coffee and had access to free reading
10:33
material and intellectual conversation as a bonus. Some argue that the cross-disciplinary
10:38
exchange of ideas facilitated by coffeehouses helped foment the intellectual revolution known
10:44
as the Enlightenment. In The World of Caffeine, Bennett Allen Weinberg and Bonnie K. Beeler
10:49
discuss how a coffee club in Oxford counted amongst its founding participants Edmund Haley
10:54
Isaac Newton, and Hans Sloan, whose personal collection formed the basis of the British
10:58
Museum. According to Weinberg and Beeler, the three men are said to have dissected a dolphin
11:03
on a table in the coffeehouse before an amazed audience, which, for the record, is generally
11:08
frowned upon in coffeehouses today, apparently. Economist Adam Smith worked on The Wealth of
11:13
Nations in a coffeehouse, meaning the beverage didn't just affect the global economy and
11:17
arguably contributed to one of the most influential books in the history of economics itself
11:22
Sometimes the building themselves even made history. The original London Stock Exchange started at a coffeehouse
11:28
Vienna also saw the rise of a vibrant coffee culture around this time. Legend has it that when the Turks tried to take the Austrian capital in the Siege of Vienna in 1683
11:37
they left behind a bag of coffee beans. That bag was the seed that sprouted the city's centuries-long love affair with the beverage
11:44
Today, Viennese coffeehouses are thought of as extensions of people's homes. Guests are encouraged to take their time and drink in the atmosphere
11:51
alongside the expertly made brews. I personally have not experienced this rich culture for myself
11:57
but I did see the movie before sunrise, so, you know, kind of the same thing
12:01
Today, tea is as British as William Shakespeare or Mr. Bean, but it wasn't accepted into the
12:06
culture immediately. By the time tea arrived in Europe in the 17th century, coffee had made
12:11
significant inroads amongst the continent's caffeine addicts. I mean, connoisseurs. Portugal was much quicker to embrace tea. The country had a direct trade route to China via
12:20
its colony in Macau, and it was viewed as a luxury by the Portuguese upper class, including
12:25
Princess Catherine of Braganza. Her future husband, Charles II, was busy restoring the
12:30
Stuart monarchy in England after five years of Oliver Cromwell's rule as Lord Protector of the
12:35
Commonwealth. Two years after ascending to the British throne in 1660, Charles married Catherine
12:40
in a politically advantageous arrangement. When Catherine came to England, she brought her fondness
12:45
for loose-leaf tea with her. She didn't introduce the beverage to the country, as is sometimes
12:49
claimed, but the new queen was a trendsetter. Drinking tea quickly became an indicator of
12:54
luxury and class. It would be more than a century before tea became the drink of the people
13:00
Though royals and nobles could afford the stuff, high taxes made it prohibitively expensive for
13:05
the majority of the population. Soon, an illegal smuggling market grew to meet the nationwide
13:09
demand for cheap tea. William Pitt the Younger put an end to this when he reduced the tea tax
13:14
from 119% to 12.5% upon becoming prime minister in 1783. Britain's legal tea market exploded
13:23
and tea smuggling was no longer lucrative—in Britain, at least. Hold that thought for later
13:27
Camellia sinensis wasn't being grown in England, which meant all the tea consumed by the country
13:32
had to be imported from China. The British and Dutch East India companies were already trading
13:37
goods with China for silks and spices so they were able to transport massive amounts of tea at a profitable rate But while China had plenty of goods that Britain wanted the British didn have much to offer in return To rectify this British merchants began smuggling opium into China to make illegal trades
13:53
The tactic worked, for a while at least. By 1839, opium was funding all of Britain's tea
13:59
The drug was so popular in China that millions became addicted to it, which predictably angered the country's leaders
14:05
This led to the Opium Wars, which were fought between 1839 and 1842
14:09
and again between 1856 and 1860. And the Opium Wars were hardly the only time the tea trade had
14:15
massive ramifications for geopolitics. May I direct your attention to Boston Harbor, 1773
14:22
Six years earlier, Britain had passed the Townsend Acts, which taxed colonists for essential goods
14:27
like tea, paper, and glass. Most of those taxes were repealed soon after, but the tea tax remained
14:32
intact. In 1773, the Tea Act gave a tax break to the East India Company on tea sent to America
14:38
America. This was meant to help the fortunes of the struggling company, and it would have
14:42
brought the price of tea down for colonists. So what's the problem
14:46
Well, much of the tea being consumed in the colonies at the time was actually being smuggled
14:50
in. Some of the founding fathers, including John Hancock, were allegedly merchants-slash-smugglers
14:56
bringing Dutch tea into the colonies. The Tea Act would have undercut this illegal activity
15:01
and, perhaps, habituated Americans into accepting British taxation. As historian Benjamin Karp laid out the argument, you're going to seduce Americans into being
15:10
obedient colonists by making the price lower. A political group called the Sons of Liberty took action
15:16
They boarded ships dressed as American Indians and dumped 340 chests of tea into the harbor
15:21
The destroyed goods were worth £9,659, or roughly $1.7 million today. This marked the colony's most overt act of defiance yet
15:31
In response, England passed the so-called Intolerable Acts, which eventually helped escalate tensions with the colonies into full-on war
15:38
You might read that the Revolution irrevocably turned America away from tea and towards coffee
15:43
It's not that simple, but there is an element of truth there. For a number of years, tea was seen as unpatriotic in the colonies
15:50
John Adams noted in a 1774 letter to his wife Abigail that he was now drinking coffee
15:55
As he said, But America got over its aversion to tea pretty quickly after achieving independence
16:05
Adams himself started drinking it again, and America began trading tea with China, producing
16:10
great wealth for many traders. In fact, it took a number of factors to convert Americans from leaves to beans
16:16
According to most food historians, the War of 1812 led to a rise in tea prices in the States
16:21
Around the same time, Brazil, located not so far from North America, was becoming a coffee powerhouse
16:26
Brazil built a massive industry, largely on the backs of enslaved Africans
16:30
In 1800, the country reportedly exported 1,720 pounds of coffee. By 1820, that figure was nearly 13 million pounds, and by 1830, it was 64 million
16:41
Increased immigration to the U.S. from coffee-drinking countries—as opposed to tea-loving England—may
16:47
have also helped shift national tastes. But the primary factor in our caffeinated conversion was probably the cost advantage
16:53
of Brazilian coffee. By the mid-19th century, coffee's popularity eclipsed tea here in the States
16:59
Of course, there are many Americans today who love tea, and an increasing number of Brits
17:03
enjoy coffee. But those old inclinations have proven surprisingly durable, and the cultural
17:08
implications of the two drinks can go beyond the simple coffee-tea dichotomy. In Britain
17:13
the way one takes their cuppa is said to correlate with social status. Historically, commoners
17:18
drank the strongest brews, while the aristocrats enjoyed weaker but better-tasting tea. The
17:24
so-called builder's tea of the British working class was so bitter that it was often sweetened
17:28
with sugar. That's why, as anthropologist Kate Fox said, taking sugar in your tea is regarded by
17:33
many as an infallible lower-class indicator. The weak tea poured in upper-crust tea rooms was
17:38
perfectly palatable on its own, which is how unsweetened tea gained its fancy reputation
17:43
It's roughly ogous to the difference between a single-source cup of black arabica
17:47
and a regular coffee here in New York City, which is generally made with
17:51
deli-quality java and a healthy dose of milk and sugar. Tea and coffee have been pitted against each other throughout history, but their similarities
17:58
may be greater than their differences. No matter what you drink at home, your loyalties may go out the window when you're jet-lagged
