Darjeeling Flushes: A Seasonal Guide to Himalayan Tea

Darjeeling is the rare tea where harvest timing is the primary quality variable, and the flush system exists to describe it.

Why Darjeeling is unusual

Grown at 600 to 2,000 metres in West Bengal, on steep Himalayan slopes with cool temperatures and persistent mist, Darjeeling produces very low yields of small, slow-grown leaves.

Most Darjeeling comes from Chinese small-leaf var. sinensis rather than the assamica used across the rest of India — a legacy of the region's origins and a major reason it tastes nothing like Assam.

The flushes

First flush (late February to April). The year's first growth after winter dormancy. Pale, greenish, floral and astringent, with the "muscatel" character only lightly present. Lightly oxidised, closer to a green or white tea than to conventional black. The most expensive and most sought after.

Second flush (May to June). The classic Darjeeling. Fuller oxidation, amber liquor, and the pronounced muscatel note — a grape-like sweetness with a faint spiced edge. For many drinkers this, not first flush, is the tea at its best.

Monsoon flush (July to September). Heavy rain produces rapid growth and diluted flavour. Mostly used for blends and bagged tea.

Autumn flush (October to November). Cooler weather, slower growth, a rounder and darker cup with less delicacy but real depth. Often good value.

Muscatel and the insect story

The muscatel character of second flush is associated with the tea jassid, a small insect whose feeding on the leaves triggers a defensive response in the plant that alters its chemistry.

This is the same mechanism behind Taiwanese bug-bitten oolongs. It means the most prized character in Darjeeling depends on a degree of insect damage, which sits awkwardly with heavy pesticide use — a genuine tension in the region.

Authenticity

Darjeeling has protected geographical indication status, and considerably more tea is sold as Darjeeling than the region produces. Look for the certification mark and, ideally, a named garden.

Brewing

First flush wants cooler water and a shorter steep than a typical black tea — treat it closer to a green. Second flush takes hotter water and around three to four minutes.

Milk is conventionally omitted. Second flush can carry it, but it buries the muscatel note you paid for.
