Guides
The Assamica Plant
The complete reference on Camellia sinensis var. assamica, the large-leaf tea plant every cup certified by this office is made from. What it is, where it grows wild, the naming dispute that took taxonomists a century to settle, and how its chemistry builds the strong cup.
Brewing Assam
The Authority's standing method for Assam: boiling water, a measured dose of leaf, and a few minutes left alone. This is the complete reference, covering water, leaf, time, milk, the second steep, CTC versus orthodox, and the test for a properly brisk cup.
The Standard on Briskness
Briskness is the word this office certifies every cup on, and it names something exact, not a vibe: a live, bright character in the liquor that the trade can put a number on. What the word means, the formula behind it, and what raises or dulls it, cup by cup.
Clones and Cultivars
Every named plant in an Assam garden carries a code, TV1, TS 397, TTRI 2, or a garden's own name and a number. The complete reference to what those codes mean, the categories Tocklai sorts its releases into, and how a candidate plant becomes a released clone at all.
Estates and Terroir
Assam tea grows on a hot, low, river-fed floodplain in northeast India. The Brahmaputra valley's heat, monsoon rain, and alluvial soil are what make the leaf malty and strong. This is the terroir, the two valleys, the estate system, and what a single garden's name on the tin actually certifies.
Assam Tea Grades
A grade names the size of the made leaf and how much golden tip rides in it, not the flavor. The complete reference: how a tea is graded, the four sizes, the orthodox lettered alphabet, the CTC codes, and what a grade does and does not promise.
Assam Tea and Health
The Authority's standing record on Assam tea and health, sorted by how strong the evidence is: what the chemistry of the cup actually measures out to, what the human trials and cohorts support, what the FDA and EFSA have and have not allowed on a label, what milk does, where the ceilings sit, and what the health record looks like in the gardens themselves.
The History of Assam Tea
The complete record of Assam tea: the wild assamica plant noted in 1823, the British annexation that opened the valley, the first eight chests sold in London in 1839, the Assam Company, the CTC machine that put Assam in the world's tea bags, and the region that grew into the largest tea producer on earth.
Manohari Gold Tea
An ultra-premium, small-batch orthodox tea from one Assam garden, hand-plucked 25 to 50 grams a day and sold at record prices. What it is, how it is made, and the full auction record, set out plainly.
The Tea Garden Community
Every cup of Assam passes through one workforce first. Who they are, how they came to the valley, what the law obliges a garden to give them, and the festival calendar the labour lines keep on their own terms.
The Assam Tea Trade
Assam tea is grown by two entirely different kinds of producer and sold down two entirely different channels, one of them compulsory by law. The canonical account of who grows it, how it reaches a buyer, what the auction settles that a private sale does not, and the rules that bind both.
The Tocklai Institute
The complete record of the Tocklai Tea Research Institute at Jorhat, the world's oldest tea research station and the office behind nearly every clone, pest study, and quality benchmark this office has ever certified. How a single chemist's post in 1891 became a formal station in 1911, what its eleven divisions do, and the science it has produced since.
Assam Black Tea of the Brahmaputra Valley
The canonical reference on Assam tea: the malty, brisk, full-bodied black tea grown in Assam, the Indian state in the Brahmaputra valley of northeast India, from Camellia sinensis var. assamica. What it is, where it grows, how it is made and graded, and where it ends up.
