First Flush
First flush is the first picking of the year on the Indian and Nepali estates, taken when the bushes break winter dormancy in early spring. In Darjeeling it produces a pale, brisk, floral tea that looks and tastes far greener than most people expect black tea to, and it is the flush that made Darjeeling's reputation abroad.

The tea year
Typical windows, not dates. Every one of these moves with the weather, the latitude and the year: the pages say by how much.
What it is
The first of a growing year's flushes, a flush being one wave of new shoots. The vocabulary belongs to the estate systems of Darjeeling, Assam and Nepal, where the bushes go genuinely dormant over a cold winter and then push growth in distinct rounds rather than continuously. The term travels: Assam and Nepal both have a first flush, and both mean something a little different by it, because their winters and their cultivars are not Darjeeling's.
When it happens
Late February through April, opening with the first spring rains. Altitude moves it substantially, and Darjeeling gardens run from roughly 600 to over 2000 metres, so a single district's first flush can be spread across weeks. The rains are the real trigger rather than the date, which is why the window shifts by a fortnight or more between years and why estates announce their first-flush lots rather than scheduling them.
What it does to the leaf
The bush has been dormant through a cold Himalayan winter and pushes its first growth slowly, in cool air and thin light, on stored reserves. That produces the familiar spring chemistry, high amino acids against relatively few catechins, and unusually aromatic young leaf. Darjeeling first flush is then deliberately underoxidised compared to conventional black tea, often well short of full, which preserves the green and floral character rather than converting it, and is why the liquor is pale and the leaf still shows green.
What it tastes like
Light, brisk and floral, with a distinct greenness and a fresh, almost astringent lift that Darjeeling drinkers describe as a spring or bite. The liquor is pale gold rather than red. Alongside a second flush from the same garden it can read as thin, and alongside an ordinary black tea it barely reads as the same category at all.
How to read it on a label
Darjeeling is protected by a geographical indication and genuine estate lots carry invoice numbers, garden names and grades, so at the serious end this is one of the better-documented harvest claims in tea. At the supermarket end the words first flush on a box of blended teabags are marketing and mean approximately nothing. The distinguishing signal is specificity: a named garden and an invoice number is a claim someone can be held to, the bare phrase is not.
What people get wrong
Brewing it like English breakfast. Boiling water and five minutes destroys a first flush, which is underoxidised and delicate and wants cooler water and a short steep, closer to how you would treat a good oolong. Adding milk is the same mistake carried further. The other error is expecting the muscatel character Darjeeling is famous for, which belongs to the second flush and is simply not what this picking does.
