Where Did Coffee Originally Come From?

Coffee originated in the forests of the Kaffa region of Ethiopia, where Coffea arabica grew wild as an understory shrub. The plant’s red cherries and seeds were first consumed by the Oromo people, who crushed the cherries with animal fat to create energy-dense food balls for warriors and hunters.

The most famous origin story involves a 9th-century Ethiopian goatherd named Kaldi. He noticed his goats became unusually energetic after eating red berries from a certain bush. Kaldi brought the berries to a local monastery.

The monks rejected the beans, throwing them into a fire. The aroma of roasting coffee filled the air. The monks raked the beans from the embers, crushed them, and steeped them in hot water, creating the first cup of coffee.

This legend, first recorded in writing in 1671 by Antoine Faustus Nairon, a Maronite professor in Rome, may or may not be true. What is certain is that the coffee plant evolved naturally in Ethiopia’s highland forests between 1,500 and 2,000 meters above sea level. Ethiopia remains the only place where Coffea arabica grows in the wild as a native species.

How Did Coffee Spread From Ethiopia to the World?

Coffee moved from Ethiopia to Yemen sometime between the 13th and 15th centuries. Sufi monks in Yemen used coffee to stay awake during long nighttime devotional prayers. They called it qahwa, a word previously used for wine.

The port city of Mocha (Al-Makha) became the center of the coffee trade. By the late 15th century, coffee was being cultivated on terraced hillsides throughout Yemen. The Arabs maintained a strict monopoly on coffee production for nearly 200 years.

They did this by parboiling all exported beans so they could not germinate. No fertile coffee seeds left Yemen legally. This monopoly made Yemeni coffee the most valuable agricultural commodity on the Arabian Peninsula.

Coffee houses called qahveh khaneh spread rapidly through the Islamic world: Mecca, Medina, Cairo, Damascus, Baghdad, and Constantinople. By 1555, the first coffee house opened in Constantinople (modern Istanbul).

Coffee became so central to Ottoman life that Turkish law allowed a woman to divorce her husband if he failed to provide her daily coffee. The Turkish coffee tradition developed into a ritualized brewing method using extremely fine grounds boiled in a cezve or ibrik, often with cardamom and sugar.

Today, you can experience this centuries-old method with a traditional copper Turkish coffee pot and extra-fine Turkish grind coffee at home.

What Role Did Coffee Houses Play in European History?

Venetian traders brought coffee to Europe around 1615. The first European coffee house opened in Venice in 1645. Within 50 years, coffee houses transformed the intellectual and political life of every major European city.

London’s first coffee house opened in 1652. By 1700, London had over 2,000 coffee houses. These establishments earned the nickname “penny universities” because for the price of a cup of coffee (one penny), you gained access to hours of intellectual discussion.

Different coffee houses attracted different professions. Lloyd’s Coffee House on Tower Street became the gathering place for ship captains and merchants, eventually evolving into the insurance giant Lloyd’s of London. Jonathan’s Coffee House in Exchange Alley became the venue where stockbrokers created what later became the London Stock Exchange.

In Paris, Café Procope (opened 1686) hosted Voltaire, Rousseau, Diderot, and Benjamin Franklin. The intellectual ferment of the French Enlightenment brewed in Parisian coffee houses. In Vienna, coffee arrived after the failed Ottoman siege of 1683, when the retreating Turkish army left behind sacks of coffee beans.

Coffee houses changed how Europeans did business, discussed politics, and consumed news. They also concerned authorities. King Charles II of England tried to ban coffee houses in 1675, calling them “places where the disaffected met and spread scandalous reports concerning the conduct of His Majesty and his Ministers.” The public outcry forced him to revoke the ban after just 11 days.

If you want to understand modern Italian espresso culture that evolved from these early European coffee traditions, our deep dive into Italian coffee rituals covers the evolution from early cafés to today.

How Did Coffee Become a Global Commodity?

The Dutch broke the Arab coffee monopoly in 1616 when Pieter van den Broecke smuggled live coffee plants out of Mocha. The Dutch East India Company established coffee plantations in Ceylon (Sri Lanka) and Java (Indonesia) by the late 1600s.

A single coffee plant from Java was brought to Amsterdam’s botanical garden in 1706. Its offspring were gifted to King Louis XIV of France in 1714. That plant’s progeny would populate nearly all coffee plantations in the Americas.

French naval officer Gabriel de Clieu carried a seedling from King Louis XIV’s tree across the Atlantic to Martinique in 1720. He shared his water ration with the plant during the difficult voyage. From that single seedling, coffee spread throughout the Caribbean and Central America.

Brazil entered the coffee trade through an unusual route. In 1727, Francisco de Melo Palheta was sent to resolve a border dispute in French Guiana. He seduced the governor’s wife, who gave him coffee seeds hidden in a bouquet of flowers. Brazil began cultivating coffee shortly after.

Brazil now produces roughly 35 percent of the world’s coffee, a position it has held for over 150 years. To understand how coffee beans from different origins taste and how to choose among them, our complete coffee bean guide covers origin characteristics, processing methods, and roast levels.

How Did the 20th Century Transform Coffee Culture?

The 20th century saw coffee transform from a locally roasted commodity to an industrial product. In 1901, Satori Kato of Chicago invented the first soluble instant coffee. By 1938, Nestlé launched Nescafé, and instant coffee became a wartime staple.

Italian inventor Luigi Bezzera patented the first espresso machine in 1901, using steam pressure to force water through coffee grounds. Desiderio Pavoni bought Bezzera’s patent and commercialized the machine. Achille Gaggia added the lever piston in 1945, creating modern espresso with crema.

If you want to try making authentic espresso at home, we have tested and ranked the best espresso machines across every budget from entry-level to prosumer setups. The Breville Barista Express gives you a built-in grinder and consistent extraction at a mid-range price point.

The 1960s and 1970s brought the “second wave” of coffee. Alfred Peet opened Peet’s Coffee in Berkeley in 1966, emphasizing dark roasts and bean origin. Zev Siegl, Jerry Baldwin, and Gordon Bowker founded Starbucks in Seattle in 1971. By the 1990s, Starbucks had thousands of locations and introduced millions of Americans to espresso-based drinks.

Coffee consumption exploded during this period. The automatic drip coffee maker became standard in American kitchens. Home brewing reached new levels of convenience with machines like the Mr. Coffee, first introduced in 1972.

For those building a complete home coffee setup, our comprehensive guide to the best coffee makers covers drip, pour over, French press, and single-serve options for every budget and brewing preference.

Myth vs Fact

Coffee History — Common Myths Debunked

Separating fact from fiction on the most common coffee history misconceptions

✗ Myth

Espresso is a specific type of coffee bean or roast level.

✓ Fact

Espresso is a brewing method, not a bean or roast. Any coffee bean can be used for espresso. The term refers solely to forcing water through finely ground coffee at 9 bars of pressure for 25-30 seconds.

✗ Myth

The Dutch legally obtained the first coffee plants for cultivation.

✓ Fact

Pieter van den Broecke smuggled the plants out of Mocha in 1616 in violation of Yemeni export laws. The Dutch East India Company built its coffee empire on contraband plants that broke the Arab monopoly.

✗ Myth

Instant coffee was invented for soldiers during World War II.

✓ Fact

Satori Kato invented soluble instant coffee in Chicago in 1901. Nestlé’s Nescafé launched in 1938. Instant coffee was already widely available before WWII, though the war greatly expanded its use in military rations.

✗ Myth

Coffee caused the Enlightenment because intellectuals gathered in cafés.

✓ Fact

Coffee houses provided the physical space for intellectual exchange, but they were a venue, not a cause. What mattered was that coffee replaced alcohol as the daytime social beverage of choice. People switched from ale to coffee, and clear-headed discussion replaced inebriated argument.

✗ Myth

The Kaldi goat story is a verified historical fact.

✓ Fact

The Kaldi legend was first recorded in writing in 1671 by Antoine Faustus Nairon, roughly 800 years after the events it describes. No contemporary evidence confirms the story. Coffee consumption by the Oromo people predates any written record, but the goat-discovery narrative is likely a charming origin myth rather than documented history.

Quick Reference

Coffee History — Key Terms Explained

Quick reference for the historical terms used throughout this guide

Qahwa
— Arabic word for coffee, originally used for wine. The term was adopted by Sufi monks in Yemen to describe the brewed coffee beverage they used for nighttime devotions.
Coffea arabica
— The species of coffee plant that originated in Ethiopia’s highland forests. Accounts for roughly 60 percent of global coffee production. All specialty coffee is arabica.
Mocha
— Port city in Yemen (Al-Makha) that was the center of the global coffee trade from the 15th through 17th centuries. The term later became associated with a chocolate-coffee drink, unrelated to the port’s history.
Penny universities
— Nickname for London coffee houses in the 17th and 18th centuries. For one penny (the price of a cup), any man could join hours of intellectual discussion with writers, politicians, and scientists.
Second wave coffee
— The period from roughly 1966 to 2000 when companies like Peet’s and Starbucks popularized dark roasts, espresso drinks, and coffee as an experience rather than just a commodity.
Third wave coffee
— The movement beginning around 2000 that treats coffee as an artisanal product. Emphasizes single-origin beans, light roasts, direct trade relationships, and precise brewing techniques.
Cezve / Ibrik
— A small copper or brass pot with a long handle used to brew Turkish coffee. Grounds are boiled with water and sugar, producing a thick, unfiltered coffee with foam on top.
Coffee rust (la roya)
— A fungal disease that devastated coffee plantations in Ceylon (Sri Lanka) in the 1860s, ending coffee production there and shifting British tea drinking habits. Still a major threat to coffee crops today.
Direct trade
— A sourcing model where roasters buy directly from coffee producers, bypassing commodity markets. Pays farmers higher prices for higher quality beans, a key principle of the specialty coffee movement.
Green coffee
— Raw, unroasted coffee beans after processing and drying but before roasting. Green coffee is the form in which coffee is traded internationally as a commodity.

What Is the Third Wave Coffee Movement?

The third wave coffee movement began around the year 2000 and treats coffee as an artisanal food product rather than a commodity. Every step from the farm to the cup receives attention: variety, growing conditions, processing method, roasting profile, and brewing technique.

Third wave roasters roast lighter to preserve origin character. They label bags with the farm name, producer, variety, processing method, and elevation. Baristas weigh every dose, measure every yield, and time every extraction. The goal is to highlight what makes each coffee unique rather than produce a consistent dark-roasted blend.

The Specialty Coffee Association (SCA) defines specialty coffee as scoring 80 points or above on a 100-point scale by a certified Q Grader. Only about 10 percent of the world’s coffee qualifies as specialty grade. The rest is commercial grade, sold as a commodity on the C market.

Key equipment from this era includes burr grinders for precise particle size control, pour over drippers like the Hario V60, and digital coffee scales with built-in timers for measuring brew ratios precisely.

For the full picture of how modern coffee brewing works across every method, our complete coffee brewing guide covers every technique from French press to pour over with step-by-step instructions and recommended gear for each method.

How Did the Colonial Coffee Plantation System Shape Global Production?

European colonial powers built coffee plantations using enslaved labor throughout the Caribbean, Brazil, and Southeast Asia. By the early 1700s, French plantations in Saint-Domingue (modern Haiti) produced half the world’s coffee. The Haitian Revolution of 1791 ended that dominance.

Brazil filled the gap. Brazilian coffee plantations expanded rapidly using enslaved African labor until abolition in 1888. After abolition, Brazil turned to European immigrant labor and continued expanding. Brazil’s coffee output grew from roughly 1 million bags in 1850 to over 15 million by 1900.

Coffee rust disease destroyed Ceylon’s coffee industry between 1869 and 1879, ending coffee production on the island. Ceylon switched to tea. The British, who had been coffee drinkers, became tea drinkers. This single plant disease reshaped British beverage culture permanently.

The commodity coffee system established in the colonial era persists today. Most coffee farmers earn well below a living income. For every $3.50 latte sold in a café, the farmer who grew the beans typically receives between 2 and 5 cents. Direct trade and fair trade certifications attempt to address this imbalance, though results vary.

To explore how different coffee origins, processing methods, and roast levels affect what ends up in your cup, our ultimate coffee guide walks through bean selection, brewing ratios, and flavor development in detail.

How Did Coffee Culture Evolve Differently Across Countries?

Every coffee-consuming country developed distinct traditions. Italy standardized espresso as a quick, standing-at-the-bar experience. A traditional Italian espresso is a 1:2 brew ratio: 7 grams of coffee yielding 14 grams of liquid in 25 seconds at 9 bars of pressure.

France developed the café crème and café au lait tradition. The French press (cafetière) became the home brewing standard. Scandinavia developed some of the world’s highest per-capita coffee consumption, with light roasting styles that preserve origin character and delicate acidity.

The United States developed drip coffee culture and later invented the Frappuccino. Australia and New Zealand perfected flat whites and created café cultures that rival Italy’s in quality. South Korea turned coffee shops into 24-hour social spaces. Vietnam became the world’s second-largest coffee producer and created its own tradition of slow-dripped coffee with sweetened condensed milk.

Japanese coffee culture deserves special mention. Japan imported coffee culture from the Dutch in the 18th century. By the 1960s, Japanese kissaten (traditional coffee houses) served meticulously prepared siphon and pour over coffee. Japanese pour over equipment from companies like Hario defined the third wave aesthetic.

For an immersive look at two of the world’s most influential coffee traditions, our guide to Italian coffee culture explains espresso rituals, regional variations, and the cultural rules that govern when and how Italians drink coffee. Our Turkish coffee deep dive covers the UNESCO-recognized tradition, fortune-telling customs, and the brewing method that has remained unchanged for 500 years.

How Much Do You Know About Coffee History?

6 questions · Takes about 2 minutes · See your result at the end

Why Did Coffee Shift From Being Brewed at Home to Being Purchased in Shops?

Home coffee brewing declined in quality throughout the mid-20th century. Pre-ground vacuum-packed coffee replaced fresh-roasted, fresh-ground beans. Automatic drip machines replaced manual brewing methods. Convenience won, but flavor lost.

The second wave coffee chains responded by offering espresso-based drinks most people could not make at home. A latte with steamed milk and flavored syrup required commercial equipment and training. The coffee shop became the default source for quality coffee.

The third wave reversed this trend by making pro-level brewing accessible at home. A Baratza Encore burr grinder costs roughly the same as a year of daily coffee shop visits and produces dramatically better coffee than pre-ground beans. A variable temperature gooseneck kettle lets you control water temperature to within 1 degree Fahrenheit for precise extraction.

The home espresso market exploded as well. Modern home espresso machines deliver café-quality shots at a fraction of the per-drink cost. A Gaggia Classic Pro with a proper burr grinder can produce espresso that rivals most cafés.

What Role Did Innovation Play in Coffee’s History?

Every major shift in coffee history was driven by a technological innovation. The cezve (Turkish coffee pot) in the 16th century made coffee brewing portable. The French press (patented 1929) gave home brewers control over steep time. The espresso machine (1901, improved 1945) created an entirely new category of coffee beverages.

The burr grinder replaced the blade grinder as the essential home tool. Blade grinders chop beans randomly, producing uneven particles from boulder-sized chunks to fine powder. Burr grinders crush beans between two abrasive surfaces, producing uniform particles essential for even extraction.

You can see the difference in the cup. Coffee ground with a conical burr grinder extracts more evenly, producing sweetness and clarity instead of the mixed sour-bitter taste that blade-ground coffee gives. This happens because uniform particles all extract at the same rate. Mixed particle sizes create simultaneous under-extraction and over-extraction in the same brew.

Digital scales and precision coffee scales with 0.1g accuracy eliminated guesswork from brewing. A 1-gram dose variation changes extraction yield by approximately 0.5 percent, enough to shift flavor from balanced to noticeably sour or bitter. Weighing both dose and yield made consistency achievable for anyone, not just trained baristas.

Can You Trace Coffee’s History Through What You Drink Today?

Every cup of coffee you drink carries its history. A Turkish coffee prepared in a traditional copper cezve connects you to the 16th-century Ottoman coffee houses where the ritual originated. An Ethiopian single-origin pour over connects you to coffee’s birthplace and the forests where arabica still grows wild.

An espresso at a 1:2 brew ratio (18g dose to 36g yield in 25-30 seconds) connects you to Achille Gaggia’s 1945 lever machine and the Italian post-war café culture that perfected the method. A cold brew steeped for 18 hours connects you to the 17th-century Dutch traders who brewed cold coffee concentrates for long sea voyages.

Coffee history is not finished. The specialty coffee movement continues to evolve, with new processing methods (anaerobic fermentation, carbonic maceration), new varieties, and new brewing techniques emerging regularly. The World Atlas of Coffee by James Hoffmann provides an excellent current reference for exploring coffee origins and culture in depth.

For a complete foundation in modern coffee knowledge, our ultimate coffee guide covers everything from bean selection to brewing techniques and will help you apply centuries of coffee history to your daily cup.

Did the Ottoman Empire Really Execute People for Drinking Coffee?

Sultan Murad IV of the Ottoman Empire banned coffee in 1633 under penalty of death for repeat offenders. The ban was enforced through brutal patrols. People caught drinking coffee were beaten, thrown into the Bosphorus, or executed. The ban lasted until Murad IV’s death in 1640.

This appears extreme but had a political logic. Coffee houses were places where people gathered to discuss politics and criticize the government. Murad IV saw coffee houses as centers of sedition. The ban was about controlling political dissent, not caffeine. Similar bans were attempted in Mecca (1511), Cairo (1532), and by Charles II of England (1675), all motivated by fear of coffee house political conversation.

How Did Coffee Survive Being Banned Multiple Times Across Different Empires?

Coffee survived every ban because demand consistently overwhelmed enforcement. In Mecca, the 1511 ban was overturned when Cairo’s Sultan, a coffee drinker himself, ordered the governor of Mecca to allow it. In the Ottoman Empire, the ban died with Murad IV. In England, the public outcry against Charles II’s proposed ban forced its revocation in 11 days.

Coffee also survived because it had become economically essential. The coffee trade generated enormous tax revenue. Coffee houses employed thousands. Banning coffee meant destroying a significant portion of the economy. Economic reality consistently defeated moral and political objections to coffee.

What Is the Difference Between First Wave, Second Wave, and Third Wave Coffee?

First wave coffee (1800s through 1960s) treated coffee as a cheap commodity. The goal was mass distribution and low price. Brands like Folgers and Maxwell House dominated. Quality was secondary to convenience and shelf stability. Instant coffee was the pinnacle of first wave innovation.

Second wave coffee (1966 through late 1990s) treated coffee as an experience. Peet’s and Starbucks introduced dark roasts, espresso drinks, and the concept of the coffee shop as a “third place” between home and work. Coffee became a luxury product with Italian names and higher prices. Origin started to matter, though dark roasting often obscured origin character.

Third wave coffee (2000 to present) treats coffee as an artisanal food product. Roasters buy direct from farms, roast light to preserve origin flavor, and label bags with farm names and processing methods. Baristas weigh every dose and yield. Consumers are expected to know variety, processing method, and elevation. The goal is expressing terroir, not consistency.

Why Does Some Coffee Taste Fruity and Other Coffee Taste Bitter?

Fruity, bright flavors come from lighter roasting and specific processing methods (washed or natural) that preserve the coffee cherry’s organic acids. Bitter, dark flavors come from darker roasting where the Maillard reaction and caramelization produce roasted, smoky compounds. The same green coffee bean can taste like berries when roasted light or like dark chocolate and smoke when roasted dark.

Origin also matters. Ethiopian coffees naturally contain high concentrations of floral and citrus compounds. Brazilian coffees tend toward chocolate and nut flavors. Processing method changes everything. Natural processed coffees, where the cherry dries around the bean, develop intense fruity flavors. Washed coffees, where the fruit is removed before drying, produce cleaner, brighter cups that showcase the bean itself.

Can I Taste Coffee the Way Professional Tasters Do?

Yes, you can cup coffee at home with minimal equipment. You need a burr grinder, hot water at 200°F (93°C), several small bowls, spoons, and fresh whole bean coffee. Grind each coffee at a medium-coarse setting. Add 12 grams of coffee to each bowl. Pour 200ml of hot water directly onto the grounds. Wait 4 minutes. Break the crust with a spoon and smell. Skim the foam off the top. Taste with a spoon, slurping to spray the coffee across your palate.

Professional Q Graders use this exact method to score coffees on a 100-point SCA scale. They evaluate fragrance, flavor, aftertaste, acidity, body, balance, sweetness, cleanliness, and uniformity. You can practice at home with two different coffees side by side. The differences become obvious when tasted next to each other in a controlled way.

Did Coffee Really Fuel the Industrial Revolution?

Coffee did not cause the Industrial Revolution, but it played a supporting role. Before coffee arrived in Europe, daytime drinking meant ale or beer because water was often contaminated. Workers operated machinery, kept accounts, and made decisions under the influence of alcohol. Coffee replaced alcohol as the daytime beverage of the working class during the 18th century.

The shift from alcohol to caffeine as the industrial workforce’s drug of choice mattered. Caffeine increases alertness and reaction time. Alcohol impairs both. A workforce drinking coffee instead of ale was more productive, made fewer mistakes, and had fewer workplace accidents. Coffee provided a legal, socially acceptable stimulant that aligned with the demands of industrial production.

What Happened to the Coffee Plantations After Slavery Was Abolished?

After slavery was abolished (British colonies in 1834, French colonies in 1848, Brazil in 1888), coffee plantations faced a labor crisis. Different regions responded differently. Brazil turned to European immigrant labor, particularly Italians, who were offered passage and land in exchange for plantation work. Conditions remained harsh and pay was low.

Other regions never recovered. Haiti’s coffee industry collapsed after the revolution of 1791. Ceylon switched to tea after coffee rust destroyed the plantations. Many Caribbean islands shifted to other crops. The legacy of colonial plantation economics persists. Most coffee-growing countries remain developing nations, and most coffee farmers live below the poverty line despite producing a product that generates over $200 billion annually in retail sales.

How Long Can Green Coffee Beans Be Stored Before Roasting?

Green coffee beans can be stored for 6 to 12 months under proper conditions without significant quality loss. Proper conditions mean 60 percent relative humidity, temperatures between 60°F and 75°F (15°C to 24°C), no direct sunlight, and protection from pests. Beans stored in GrainPro bags or vacuum-sealed containers at stable conditions can remain viable for up to 18 months.

After about 12 months, green coffee begins to fade. Acidity drops first. Floral and fruity notes diminish. The coffee tastes flat and woody. This is called “past crop” flavor. Roasters can compensate slightly by roasting darker, but the original character is gone. This is why specialty roasters pay attention to harvest dates and ship by air rather than sea when freshness matters for competition coffees.

What Was Coffee Like Before the Invention of the Espresso Machine?

Before the espresso machine (patented 1901), all coffee was brewed using some form of steeping or percolation. Turkish coffee was boiled in a cezve. French press steeped grounds and water together. Drip methods used cloth filters. Percolators cycled boiling water through grounds repeatedly. Each method had its own flavor profile, but none produced the concentrated, crema-topped shot we recognize as espresso.

The defining characteristic of pre-espresso coffee was lower concentration and longer brew times. A typical cup was 6 to 8 ounces (180-240ml) brewed over 3 to 5 minutes. Espresso compressed the entire experience into 1 to 2 ounces (30-60ml) extracted in 25-30 seconds at high pressure. This concentration enabled milk drinks like lattes and cappuccinos that had no pre-espresso equivalent.

Can Mold Grow in Coffee Beans or a Coffee Grinder?

Mold can grow on green coffee beans if moisture content exceeds 12.5 percent during storage. This is why proper drying after processing is essential. Once roasted, coffee beans are nearly sterile and dry enough that mold cannot grow on them under normal storage conditions. Ground coffee is more vulnerable to moisture absorption. Store ground coffee in an airtight container away from heat and humidity.

Coffee grinders can accumulate stale coffee oils that go rancid over time. These oils trap moisture and old coffee particles, creating an environment where mold can grow, especially in humid climates. Clean your grinder burrs every 2 to 4 weeks using grinder cleaning tablets or a brush. For espresso machines, backflush with water after every session and use a cleaning detergent weekly to prevent rancid oil buildup in the group head.

What Is the Single Most Important Innovation in Coffee History?

The burr grinder is arguably the single most important innovation for coffee quality. Every brewing method depends on uniform particle size for even extraction. The burr grinder made uniform grinding accessible and affordable. Before burr grinders, home coffee drinkers used blade grinders or bought pre-ground coffee, both of which produce uneven extraction and mixed sour-bitter flavor.

A close second is the espresso machine, which created an entirely new category of coffee beverages. The combination of fine grind, high pressure, and short contact time produces concentration and crema impossible to achieve with other methods. Every latte, cappuccino, flat white, and macchiato exists because of the espresso machine. The two innovations together (burr grinder plus espresso machine) created the modern coffee landscape.

The history of coffee continues evolving with every innovation in farming, processing, roasting, and brewing. Understanding where coffee came from enriches every cup you drink.
