Tea has been a central part of human culture for millennia, enjoyed for its diverse flavors, soothing properties, and health benefits. From ancient ceremonies in China to contemporary cafes in every corner of the globe, tea continues to unite people in moments of relaxation, reflection, and social connection.
History and Origins
Tea originated in ancient China, where legend credits Emperor Shennong with discovering it around 2737 BCE when tea leaves accidentally drifted into his boiling water. Over centuries, tea cultivation and processing evolved:
- Tang Dynasty (618–907 CE): Tea became China’s national drink and spread to Japan via Buddhist monks.
- Song Dynasty (960–1279 CE): Innovations in tea preparation, including powdered tea and whisking techniques.
- Ming Dynasty (1368–1644 CE): Shift from powdered to loose-leaf tea and introduction of new processing methods.
- Global Spread: European traders introduced tea to Britain in the 17th century, where it became a cultural staple and spurred the establishment of tea plantations in India and Ceylon (Sri Lanka).
Types of Tea
All true teas are derived from the leaves of the Camellia sinensis plant. The key distinctions arise from how leaves are processed:
Green Tea
Green tea leaves are quickly heated (by pan-firing or steaming) to halt oxidation.
- Flavor: Fresh, vegetal, with grassy or seaweed notes.
- Examples: Sencha, Matcha, Longjing (Dragon Well).
Black Tea
Black tea undergoes full oxidation, which darkens leaves and intensifies flavor.
- Flavor: Bold, malty, sometimes fruity or smoky.
- Examples: Assam, Darjeeling (Second Flush), Earl Grey.
Oolong Tea
Oolong is partially oxidized, placing its profile between green and black teas.
- Flavor: Complex, floral, with varying degrees of roastiness.
- Examples: Tieguanyin, Da Hong Pao.
White Tea
White tea is minimally processed and rarely oxidized, using young buds and leaves.
- Flavor: Delicate, sweet, with light floral notes.
- Examples: Silver Needle, White Peony.
Pu-erh Tea
Pu-erh undergoes microbial fermentation and aging, resulting in earthy, mellow flavors.
- Flavor: Deep, woodsy, sometimes mushroom-like.
- Types: Raw (sheng) and ripe (shou) pu-erh.
Health Benefits
Tea is celebrated not only for its taste but also for its wellness-promoting compounds:
- Antioxidants: High in polyphenols like catechins (in green tea) and theaflavins (in black tea), which combat free radicals.
- Heart Health: Regular tea consumption may support healthy blood pressure and cholesterol levels.
- Cognitive Function: L-theanine, an amino acid found in tea, can promote relaxation and sharpen focus.
- Digestive Support: Certain teas (e.g., peppermint, ginger) soothe the stomach and aid in digestion.
- Hydration: Despite containing caffeine, tea contributes to daily fluid intake.
Brewing Methods
Proper brewing maximizes flavor and health benefits. Key variables include water temperature, steeping time, and leaf quantity.

| Green Tea | 75–85 °C | 1–3 minutes | 2 g per 200 ml |
| Black Tea | 95–100 °C | 3–5 minutes | 2–3 g per 200 ml |
| Oolong Tea | 85–95 °C | 2–4 minutes | 2 g per 200 ml |
| White Tea | 80–85 °C | 4–5 minutes | 2–3 g per 200 ml |
| Pu-erh Tea | 95–100 °C | 2–3 minutes | 3 g per 200 ml |
