India as an origin
Indian Coffee Varieties: S795, Sln 9, Cauvery and Kent
An Indian offer list names varieties most European buyers have never seen. They are not obscure — they are the product of a century of breeding for leaf rust in a country that had it early and badly.
Latin American variety names travel: Bourbon, Typica, Caturra, Geisha. Indian ones do not, and a buyer reading an Indian offer list for the first time usually recognises none of them.
The reason is history. Coffee leaf rust reached India in the nineteenth century and devastated the arabica plantings. What followed was a long institutional breeding programme aimed at resistance, and the varieties on Indian farms today are its output.
S795
The most widely planted arabica in India, and the one you are most likely to be offered.
A selection from a Kent × S288 cross, S288 itself carrying Coffea liberica ancestry — which is where the rust tolerance comes from. Released in the mid-twentieth century and still dominant on estates that value cup over yield.
In the cup: heavier bodied than most Latin American arabica, with cocoa, spice and a rounded low acidity. It is the variety most responsible for the Indian arabica profile European buyers describe as "soft".
Sln 9
A Hibrido de Timor cross — Timor being the natural arabica × robusta hybrid that underpins most modern rust resistance worldwide — developed at the Central Coffee Research Institute.
More resistant than S795 and generally higher yielding. Selection 9 has performed well in Indian cupping competitions, which is unusual for a rust-resistant line and worth knowing if you carry the standard assumption that resistance costs cup quality.
In the cup: cleaner and brighter than S795, with more defined acidity. Where an Indian lot surprises a buyer on the table, it is often this.
Cauvery
The Indian name for Catimor — Caturra × Hibrido de Timor.
Short, high yielding, strongly rust resistant, and planted widely where the economics of the farm matter more than the top of the cup. Catimor's reputation globally is that it trades cup quality for productivity, and that is broadly fair here too, though it varies a great deal with altitude and processing.
In the cup: functional. Fine in a blend, rarely the star.
Kent
The oldest of the four, named after the planter on whose Mysore estate it was selected in the 1920s. It was among the first rust-tolerant selections anywhere and is an ancestor of S795.
Little is planted now. Where it survives it is usually on old blocks nobody replanted.
In the cup: sweet and delicate compared with its descendants, but low yielding and no longer resistant to current rust races.
Robusta varieties
Robusta plantings are less formally differentiated, though S274 is the long-established Indian robusta selection. The more useful questions for robusta are processing and picking rather than variety — see Indian robusta.
A summary table
| Variety | Parentage | Rust resistance | Yield | Cup |
|---|---|---|---|---|
| S795 | Kent × S288 | Moderate | Moderate | Body, cocoa, spice |
| Sln 9 | Hibrido de Timor cross | High | Good | Cleaner, more acidity |
| Cauvery | Catimor | High | High | Functional |
| Kent | Selection | Low now | Low | Sweet, delicate |
What to ask
Variety is less predictive in India than in, say, Colombia, because shade cover and processing shift the result more than the plant does. Ask about variety, but weight the answer accordingly.
The more useful questions are usually: which blocks, at what altitude, picked how many times, and processed how. A well-picked Cauvery from a high shaded block will beat a carelessly stripped S795 every time.
Hoysala’s blocks run from 900 m to 1,450 m in Chikmagalur, with about 65% of the estate under shade — a spread wide enough that the same variety behaves differently at the top and the bottom of it.
