Nilgiri
The Nilgiris are the Blue Mountains, a high plateau in the Western Ghats and the largest tea district in southern India. It is tropical and high at the same time, which is the whole story: the bushes never go properly dormant, so leaf comes off them in every month of the year, and yet the tea the district is actually judged on is made in the few cold weeks when growth finally slows down.
What grows here
Nilgiri black tea, bright and brisk and mostly headed for blends, in both CTC and orthodox form. The cold-season lots are the specialty end, frost tea above all. A small number of gardens also make green, white and oolong-style teas from the same bushes, which is a recent development here rather than a tradition.
The ground
Gardens run from roughly 1,000 m up to over 2,400 m at Korakundah, the highest tea garden in India, on a plateau that catches two monsoons: the southwest from June to September and the northeast from October to December. Between and after them sit the cool dry windows, and that is when the good tea is made. The district also sits at about eleven degrees north, where the shortest day is still close to eleven and a half hours, never short enough to trigger the winter dormancy that shuts Assam and Darjeeling down at twenty-seven degrees. Continuous growth is a yield advantage and a quality problem at the same time.
The bushes
Counterintuitively for tea grown this high, most of the planting is assamica-derived rather than the China-type bushes Darjeeling uses, and that is part of why a Nilgiri is brisk and full rather than delicate. On top of the older seedling stock sit the UPASI clones, bred in the south for southern conditions and selected mainly for yield and resistance rather than for aroma.
Harvest seasons
Picking runs the whole year, which is unusual in India and is why Nilgiri is a blender's staple: supply does not stop. Quality does move, though. The monsoon months give volume and little else, while the cool dry season from around December into February gives the concentrated aromatic lots, with frost tea at the sharp end of it, made from leaf that has sat through nights below freezing in January and February. Buying Nilgiri without asking when it was picked is buying the average of a year.
How it is made here
Most Nilgiri leaf is not processed by the person who grew it. Smallholders cut and deliver green leaf, often with shears rather than by hand, to a bought-leaf factory that pools it and runs it through a CTC line the same day. UPASI, the southern planters' research body, recommends alternating shears with hand plucking, because shearing measurably cuts the theaflavins a black tea is judged on. That chain sets the ceiling: coarse plucking and pooled leaf make a serviceable blending tea and cannot make a fine one. The orthodox and frost lots come from the minority of gardens that control their own leaf from bush to dryer, which is why they are a separate product.
What to look for
Nilgiri is a trading category before it is an origin, so the useful questions are orthodox or CTC, which garden and which month. The estates that grow the leaf, run their own factory and sell under their own name are the ones worth learning, Chamraj, Craigmore, Havukal and Glendale among them, because they are the exception to the pooled-leaf norm rather than an example of it. Frost tea is the most copied claim in the district, because the word is worth more than the leaf: it should come with a specific garden and a named winter behind it, not just the word frost on a packet.
