Assam
Black tea
About this tea
Assam tea is a bold, malty, and full-bodied black tea from the Brahmaputra River valley of northeastern India — the world's single largest contiguous tea-growing region. Made from the native Camellia sinensis var. assamica, a broad-leaved variety that thrives in tropical lowland conditions, Assam produces deeply colored, rich infusions with a distinctive malty sweetness. It forms the backbone of nearly every English and Irish Breakfast blend and is the most widely consumed tea variety in India's beloved chai.

Origin & Production
The Assam tea region stretches along both banks of the Brahmaputra River in northeastern India, spanning over 300 kilometers at near sea-level elevation (45–120 meters). Upper Assam around Dibrugarh and Tinsukia produces the finest single-origin teas, while Lower Assam around Nagaon and Darrang yields the bulk production used in blending. The monsoon climate — with heavy rainfall (2,500–3,000 mm annually), high humidity, and temperatures between 20–35°C — creates ideal conditions for the assamica tea plant.
Production process
Plucking
Two leaves and a bud are machine- or hand-plucked during the growing season (March–November), with the second flush (May–June) yielding the most prized 'tippy' golden leaves.
Withering
Fresh leaves are withered for 12–18 hours on troughs with warm air flow, reducing moisture by 60–70% and softening them for processing.
CTC or orthodox rolling
Most Assam is processed via CTC (Crush, Tear, Curl) machines that produce small, uniform granules ideal for tea bags. Orthodox rolling produces larger, twisted leaves for premium grades.
Full oxidation
Assam teas are fully oxidized for 2–4 hours in humid, temperature-controlled rooms, developing their characteristic deep copper-red color and malty flavor.
Firing & sorting
Leaves are fired at 90–95°C to halt oxidation, then sorted by size into grades: whole-leaf FTGFOP, broken BOP, fannings, and dust.
History & Tradition
The discovery of tea growing wild in Assam changed the course of the global tea trade, breaking China's centuries-old monopoly and launching India as the world's largest tea producer.
Robert Bruce's discovery
Scottish adventurer Robert Bruce encountered wild tea plants growing in Upper Assam's jungles, guided by Singpho tribal chief Bessa Gam. He collected samples but died before they could be scientifically analyzed.
First Assam tea at London auction
The Assam Company shipped the first commercial batch of Assam tea to London, where it was sold at auction — marking the birth of the Indian tea industry.
Plantation boom
British planters rapidly expanded tea gardens across the Brahmaputra valley. By 1870, Assam had over 300 tea estates, producing thousands of tons annually.
CTC revolution
The adoption of CTC processing machines transformed Assam production, enabling the fast-brewing, strong tea that would dominate tea bags and Indian chai stalls worldwide.
Health Benefits
High caffeine energy
Assam var. assamica naturally contains more caffeine than var. sinensis — a typical cup delivers 60–90 mg, making it one of the most stimulating non-espresso beverages available.
Theaflavin-rich
Full oxidation of assamica leaves produces exceptionally high levels of theaflavins — antioxidants shown to reduce LDL oxidation and support immune cell function.
Mental sharpness
The combination of robust caffeine and L-theanine in Assam provides a powerful yet smooth cognitive boost — improving alertness, reaction time, and task focus.
Heart health support
Regular Assam tea consumption has been linked to improved endothelial function and healthy blood pressure regulation, attributed to its rich flavonoid and polyphenol content.
Metabolic activation
Black tea polyphenols from Assam have demonstrated ability to modulate gut microbiota composition and promote short-chain fatty acid production, supporting metabolic health.
Grades & Varieties
