The World’s Top 3 Drinks: Coffee, Tea, and Cola

You’ve heard coffee is one of the world’s top three drinks—but what exactly defines it? Why does coffee have such a distinct reputation for bitterness, energy, and aroma? Whether you're new to specialty coffee or just curious about its global role, this guide breaks down everything from flavor profiles to cultivation and brewing.

Coffee ranks among the world’s three most consumed beverages alongside tea and cola. It’s known for its dark color (typically a brewed amber), strong aroma, and complex taste profile including bitterness, acidity, sweetness, richness, and fragrance. Its stimulating effects come from caffeine and other compounds, making it a go-to for energy and focus.

What Is Coffee? Four Tastes and One Aroma

Coffee is more than just a black, bitter drink. It presents a balance of five sensory elements: fragrance (aroma), bitterness, acidity, sweetness, and body (richness). These elements define quality and origin. The fragrance—coffee’s most elusive trait—is considered its lifeblood, reflecting both growing conditions and roast technique. A well-brewed cup can evoke anything from fruity and floral to nutty and chocolatey notes.

Coffee’s Role and Effect on the Body

Beyond stimulation, coffee offers several physiological effects. It acts as a stimulant, boosts alertness, helps with hangover relief, reduces fatigue, improves heart function, and aids digestion. Key chemical components include caffeine, tannic acid, fatty acids, proteins, sugars, water, and various minerals—all contributing to its distinctive impact on the body.

The Origins of Coffee Culture and Equipment

The term “COFFEE” was coined by Arab physician Rhazes (or Al-Razi). The first known coffeehouse opened in Istanbul, Turkey. Coffee brewing has evolved through multiple methods, each affecting flavor and body differently:

• Siphon (Vacuum Pot)
• Italian (Espresso) Maker
• Drip (Water Drop) Method
• Paper Filter Brewing
• Felt (Flannel) Filter
• Ibrik (Turkish Coffee Pot)
• Percolator

Key historical figures include Englishman Robert Napier (siphon inventor), Italian Richard Saliba (espresso pot), and Arab doctor Rhazes (who named coffee).

Where Coffee Grows: Regions, Altitude, and Conditions

Coffee thrives near the equator in tropical and subtropical zones. Major producers include:

• Brazil – ~30% global production
• Colombia – ~10% global production
• Central and South America – ~60% combined
• Africa and Arabia – ~30%
• Asia & Pacific islands – ~10%

Coffee plants grow best at 300–2500 meters altitude, often interspersed with shade trees like bananas, mangoes, and sunflowers. Ideal conditions include 1500–2000 mm annual rainfall, average temperatures around 20°C, and protection from frost, wind, direct sun, and extreme heat.

The Coffee Plant: Species and Characteristics

Wild coffee trees can reach 8 meters, but cultivated varieties are pruned to 2 meters for manageability and quality. Most plants begin fruiting in 3–5 years, remain productive for 5–20 years, and yield 3–5 kg of cherries annually—with only 20% (about 1 kg) being usable coffee beans per tree.

The Three Main Coffee Species

• Arabica (Coffea arabica): Originating in Ethiopia (historically Abyssinia), Arabica grows at high altitudes and is prized for its superior cup quality. It represents the top tier among coffee species.
• Robusta (Coffea canephora, formerly C. robusta): Native to the Congo, Robusta is hardy, disease-resistant, and thrives at lower altitudes. It produces a stronger, harsher flavor and accounts for about 30% of global production, commonly used in instant coffee.
• Liberica (Coffea liberica): From Liberia, this species has a late cultivation history, weaker aroma, and stronger bitterness. It is less common commercially.
