TV1

The first clonal cultivar released by the Tocklai Tea Research Institute in Assam, and the beginning of systematic clonal planting in India. It remains widely grown for its vigour and heavy cropping.

Where it sits in the botany

TV1 is recorded under Camellia sinensis var. assamica, the variety group one level above cultivar. It is associated with India, which is where it was selected or is most widely planted rather than the only place it grows.

Registration code: TV1. A breeding or registration code identifies the selection in an institutional register and is often the name a grower uses when the trade name is not.

Also transliterated as: tocklai vegetative 1.

What the plant is like

Assam’s shift from seed-grown gardens to clonal ones is what made single-estate consistency possible, and TV1 is where that shift starts.

Why a grower plants it

Yield, hardiness, when it buds, what it resists and whether a machine can cut it. This is the half of a cultivar’s identity that decides what is actually in the ground, and it is usually left out of writing aimed at drinkers.

Vigorous, heavy-cropping and easy to propagate, which is the whole reason a first clone succeeds: it has to convince planters that a cutting is worth the trouble against seed they can collect themselves. It suits the Assam pattern of a hard first and second flush with a monsoon crop behind it, and it tolerates the valley's heat and humidity. Its real agronomic significance is not any single trait but what a clone makes possible — a field where every bush breaks bud within a few days of every other, which is the precondition for machine plucking, for a scheduled factory and for a garden that can promise the same tea twice.

What it does in the cup

Reported as giving a full, strong, coloury liquor suited to both CTC and orthodox manufacture, in the ordinary Assam idiom rather than as a distinctive tea. It is a base rather than a signature.

How much of this is really the cultivar?

An Assam is decided by flush, by manufacture and by how much tip the sort leaves in, in roughly that order, and the clone comes some way behind all three. The shift from seed to clone did change the district's tea, but the change was toward uniformity rather than toward any particular flavour — a modern Assam garden tastes more like itself year to year than it did, which is a different thing from tasting like TV1. Second-flush character in particular tracks the season and the leaf's exposure to jassid feeding rather than the plant.

Cultivar, growing site and processing all shape a cup, and the cultivar is very often the smallest of the three. It is also the one that fits on a label, so almost every commercial incentive runs toward overstating it. This section is on every cultivar page that has been reviewed for it, including the ones where the honest answer is “less than you would think”.

What it is usually made into

The categories this cultivar is typically processed into. It is a statement about common practice, not a limit — processing decides the category, and a cultivar can be taken down more than one route.

Black tea — Tea taken deliberately through full enzymatic oxidation, giving the dark leaf, amber-to-red liquor and malty or brisk character most Western drinkers think of as simply 'tea'.

Guides covering this cultivar

Climate change and tea: what changes, and what adaptation looks like — Tea is a long-lived perennial pinned to a specific hillside, grown in a climate envelope that is narrower than most crops. This page sets out the mechanisms by which a changing climate reaches the bush, and what the available responses actually involve.
Bush age, replanting and carbon in a tea field — A tea bush is a decades-long investment that eventually stops paying. What a producer does about that — nothing, infilling, rehabilitation or full replanting — has consequences for yield, for soil and for the carbon held in the field, and the decision is almost always financial.
Reading a cultivar code: TV1, TRI 2043, TRFK 31/8, Taicha No. 18 — Half the world’s tea plants are known by codes rather than names, and the codes are not arbitrary. Each one records which institution made the selection and, often, where in its programme the plant sits.

Written comparisons

Where TeaHQ has set this cultivar against something it is routinely confused with, and argued the differences out in full.

AV2 vs TV1 — The clonal cultivars that mark the shift from seed-grown gardens to propagated ones in India’s two most famous regions. TV1 is where that shift starts in Assam; AV2 is what it produced in Darjeeling two generations later.
TV1 vs TV23 — Two Assam clones released decades apart into an industry that changed what it wanted in between. TV1 is where Assam’s shift from seed-grown gardens to clonal ones begins; TV23 is what that programme produced once CTC had become the destination for most of the crop.
