Understanding Tea Flushes: A Guide to Seasonal Tea Harvests
Tea dances through the seasons. Each harvest — or "flush" — produces leaves with a distinct flavour profile shaped by temperature, rainfall, and how much time the plant has had to rest and rebuild since the last picking. Understanding flushes helps you make more intentional choices about which teas to drink and when.
1. First Flush: Spring's Delicate Prelude
The first flush marks the beginning of the harvest season, typically arriving in late February to April in Nepal's eastern hills as temperatures begin to rise after winter dormancy.
These young buds and first leaves are among the most prized in tea. They are light in the cup, high in amino acids (especially L-theanine, which hasn't yet converted to other compounds through summer growth), and carry the freshest aromatic character of the year. First flush teas are often the most expensive because they are the most limited — the plant has produced nothing since the previous autumn.
Flavour profile: Light, floral, delicate. Bright pale liquor. Examples: Nepal Hills' Floral Green Tea and Floral White Tea showcase this spring character.
2. Second Flush: Summer's Bold Statement
The second flush arrives in June and July, once the spring growth has matured. Leaves are bigger, the plant's chemistry has shifted, and the resulting tea is bolder and more complex.
This is the flush that produces Nepal's famous muscatel teas — the honey-grape, dried apricot character that develops as summer warmth interacts with the leaf. In Darjeeling, second flush muscatel is the most sought-after tea in the world. Nepal's Ilam produces its own version with comparable complexity.
Flavour profile: Malty, full-bodied, sometimes muscatel. Amber liquor. Nepal Hills' Muscatel Black Tea — honey-grape, dried apricot, light rose — exemplifies this second-flush character.
3. Monsoon Flush: Rain's Influence
From July through early October, the monsoon delivers heavy rainfall to Nepal's eastern hills. Tea plants grow quickly during this period, but dilution from rain and accelerated growth produces leaves with less concentrated flavour.
Monsoon flush teas are typically earthier and mellower — less complex than first or second flush. They're often used for blending or everyday drinking rather than specialty single-origin teas. Nepal Hills does not source monsoon flush teas for this reason.
Flavour profile: Earthy, mellow, medium-bodied. Best suited to everyday blends.
4. Third Flush / Autumn Flush: The Season's Golden Close
As monsoon rains ease from October to mid-November, a final flush emerges. Autumn teas have a distinctive character: the cooler temperatures and drier air produce leaves with woody, nutty notes and a warm coppery liquor. These are often well-balanced, easy-drinking teas.
Nepal Hills' Special Black Tea (Theba Black) from Taplejung — dark chocolate, dried plum, pine resin — captures the complex aromatic depth that autumn harvesting at 6,000 ft produces.
Flavour profile: Rich, woody, nutty. Warm coppery liquor. Less astringent than second flush.
5. Dormant Stage: Tea's Winter Rest
From mid-November through February, Nepal's tea plants enter dormancy. Growth slows dramatically and no meaningful harvest is possible. This rest period is critical to the plant's health and to next year's first flush quality — the plant rebuilds its amino acid reserves and resets for a new season.
Pruning is typically done during dormancy: removing old branches and shaping the bush encourages vigorous new growth and ensures the first-flush buds emerge from productive young wood rather than old woody stems.

Frequently Asked Questions About Tea Flushes
What is first flush tea?
First flush is the first harvest of the tea season, typically occurring in late February to April in Nepal and Darjeeling. These are the youngest, most delicate leaves of the year — the first buds that emerge after winter dormancy. First flush teas are prized for their freshness, light floral character, and high amino acid content. They are typically the most limited and expensive of the annual harvests.
Why is second flush tea bolder than first flush?
By June and July, tea leaves have had more time to mature and develop a different chemical profile than spring buds. Summer temperatures trigger the development of theabrownines and other compounds that produce malty, full-bodied flavours. The muscatel character — honey-grape notes found in Darjeeling and Nepali summer teas — is specifically a second-flush phenomenon driven by warmth and specific leaf biochemistry.
How many flushes does Nepali tea have per year?
Nepal's tea calendar includes four main seasons: first flush (spring, February–April), second flush (summer, June–July), monsoon flush (July–October), and autumn flush (October–November), followed by winter dormancy. First and second flush teas are generally considered the highest quality. Nepal Hills sources primarily from first, second, and autumn flush harvests.
What does dormancy mean for tea quality?
The winter dormancy period (mid-November through February) is when the tea plant rests and rebuilds its nutritional reserves. Without this rest, the first-flush leaves would not develop the same delicacy and amino acid richness. Dormancy is directly linked to the freshness and complexity of spring teas. It also allows farmers to prune and shape plants for the upcoming season without disrupting active harvest.
