Assam Second Flush Tea: A Complete Guide

Assam tea has several harvest seasons but not all harvest seasons are the same. Assam’s tea grows at low altitude with its tea estates benefitting from the flood plains of the Brahmaputra river. Centuries of silt deposits have left the soil rich, alluvial and naturally fertile which provides a strong foundation for the tea bushes' growth. In Assam, tea is harvested from March to mid December. Four distinct harvest seasons, made up of growth periods called a “flush”, with resting periods between flushes, called the “bhanji”. While every season presents its unique teas, the most famous are the ones produced in spring called the “second flush”.  Assam teas are known for their robust flavor, malty notes and deep amber color, making them an ideal choice for chai lovers.

What Is Second Flush?

Assam tea is harvested in flushes or picking seasons, throughout the year and each one produces a noticeably different cup. Assam’s second flush represents the peak season and is typically harvested between mid May and June. It is during this short window that the early monsoon heat and humidity push the leaves into a growth spurt that concentrates flavour rather than diluting it. This monsoon heat is shaped by a few key factors working together : warm temperatures in the range of 25 to 30 degrees Celsius, moderate sunshine, high humidity, and well-distributed rainfall rather than continuous downpours. Together, these conditions allow the shoots to grow steadily, producing mature shoots while developing a high concentration of flavour. As a result, they produce a rich colour when brewed. The more the second flush tea leaves mature, the stronger their aroma is. A cup of second flush tea has a malty flavour, is full bodied, bold and brisk. 

Why Does Second Flush Tea Tastes So Different ?

The second flush tastes the way it does because several things happen at once during this brief window. The rising heat speeds up the tea bush's metabolism, concentrating the sugars and aromatic compounds inside the leaf rather than diluting them, while the arrival of the monsoon brings the humidity needed to sustain vigorous new growth. Second flush tea is made in two styles, Orthodox and CTC. Each has its own character, but both carry the same signature richness. At the same time, the orthodox leaves reach a stage of maturity where golden tips emerge, adding sweetness and complexity to the final cup. CTC, short for Crush, Tear, Curl, is made by passing the leaves through machine rollers that shred them into small, uniform pellets rather than rolling them whole. This process ruptures more of the leaf's cell structure, giving CTC its quick, punchy strength and a cup that stays bold even with milk.  This window is prime time for these tips which are the sweetest and the most flavourful part of the plant. Together, these conditions are what give second flush its signature malty richness, full body and deep amber colour,  a flavour profile that simply can't be replicated in any other harvest. Second flush leaf can go either way and the choice really comes down to what you're after. Orthodox for a more refined, sip-and-savor experience, or CTC for a bold brew that holds its own taste against milk and spice. 

How to Brew It

Assam second flush is forgiving, but a few adjustments bring out its best qualities.

For a straight cup (no milk for orthodox tea):

• Water temperature: 95 – 100°C (just off the boil)

• Leaf: About 2 teaspoon per 200ml cup

• Steep time: 3 – 4 minutes

• Longer steeping brings out more malt but also more tannin, so adjust to taste

For milk tea or chai ( CTC ) :

• Use a CTC grade, since milk mutes flavor

• Steep 4 – 5 minutes, or simmer briefly if making chai

• Add milk after steeping, then sweeten to taste

A note on water: soft water brings out more of the tea's sweetness, while very hard water can emphasize bitterness. If your tap water is heavily mineralized, filtered water will noticeably improve the cup.
