What are tea flushes? A Comprehensive Guide to Understanding Different Harvesting Seasons

Mar 27, 2024
Tea is a gift nurtured by nature. Almost every aspect of your favourite cup of tea is defined mostly by the environment it inhabits. From the serene hills of Darjeeling to the lush fields of China, each tea is unique and vibrant. The climate, soil, or even the wind pattern can result in a unique cup of tea depending on its surroundings. Similarly, tea flushes are also a crucial aspect of tea cultivation. So, we are going to unravel the mysteries of tea flushes and explore the myriad varieties they offer!

What is a tea flush?

Tea flushes refer to the distinct stages of growth in the tea plant (Camellia sinensis), during which new leaves and buds sprout. These flushes are categorised based on the maturity of the leaves and the time of year they are harvested. The three primary flushes are the first, second, and autumn, each offering unique characteristics and flavours.

Understanding Tea Flushes

Flushes play a pivotal role in determining the quality and taste profile of the tea. However, knowing that every tea may not have specific tea flushes is important. Some countries do not experience seasonal variations and enjoy the sun and rainfall throughout the year. This type of tea-growing nation can harvest its teas in very short cycles, such as once a week or even less. Tea-producing countries like Kenya, Ceylon (Sri Lanka), and even some parts of India enjoy the privilege of harvesting the teas throughout the year. However, these countries, too, can have different flavour seasons, depending on specific climatic conditions or the dry seasons.

On the other hand, in seasonal tea gardens, tea plants enter a dormant phase during the Winter months. With the arrival of spring and the warming of the weather, these tea plants gradually awaken, unfurling their leaves and entering a new growth cycle. It's during this awakening that the magic of tea flushes unfolds. Each flush, distinguished by its timing and the maturity of the leaves, contributes distinct flavour profiles to the teas produced. Therefore, the precise moment when the tea is plucked significantly determines its taste and character.

Types of Tea Flushes

The First Flush

  • Characteristics: The first flush, also known as the "spring flush," marks the initial harvest of the year. The leaves harvested during this period are tender and delicate, reflecting the rejuvenating essence of spring. They are typically light green and exhibit a subtle, fresh aroma.
  • Seasonality: First flush teas are harvested in early spring, usually between March and May, depending on the geographical location and climate of the tea-growing region.
  • Popular Regions Producing First-Flush Teas: Some renowned regions known for producing exquisite first-flush teas include Darjeeling in India, Uji in Japan, and Huangshan in China.
  • Flavour Profile: First flush teas are celebrated for their light, floral notes and delicate, nuanced flavours. They often possess a crisp, brisk taste with hints of sweetness and a subtle astringency.
  • Notable First Flush Teas: Notable examples of first flush teas include Darjeeling First Flush, renowned for its floral aroma and muscatel flavour, and Uji Gyokuro from Japan, prized for its vibrant green colour and umami-rich taste.

The Second Flush

  • Characteristics: The second flush, referred to as the "summer flush," follows the first flush and is characterised by the maturation of tea leaves. The leaves harvested during this period are more developed, with a deeper colour and fuller flavour profile.
  • Seasonality: Second-flush teas are typically harvested in late spring to early summer, between May and July in most tea-growing regions.
  • Regions Known for Second Flush Production: Assam in India and parts of China, such as Yunnan and Fujian provinces, are renowned for producing second-flush teas.
  • Flavour Profile: Second-flush teas are prized for their rich, full-bodied flavours and complex aromas. They often exhibit a malty sweetness with hints of fruity notes and a smooth, lingering finish.
  • Notable Second Flush Teas: Examples of second flush teas include Assam Second Flush, known for its bold, brisk character and golden-tipped leaves.

Autumn Flush

  • Characteristics: The autumn flush, also known as the "fall flush," represents the final harvest of the tea-growing season. The leaves harvested during this period undergo further maturation, resulting in a deeper colour and intensified flavour profile.
  • Seasonality: Autumn flush teas are harvested in autumn, typically between September and November, as the weather cools and the days shorten.
  • Regions Where Autumn Flush Teas Are Produced: Regions such as Darjeeling in India, Taiwan, and parts of China, including Fujian and Yunnan provinces, are known for producing autumn flush teas.
  • Flavour Profile: Autumn flush teas often exhibit a robust, earthy flavour with pronounced autumnal notes. They may possess a mellow sweetness with hints of dried fruits and spices, offering a warm and comforting brew.
  • Notable Autumn Flush Teas: Notable examples of autumn flush teas include Darjeeling Autumn Flush, appreciated for its rich, musky aroma and bold, complex flavour profile, and Taiwanese High Mountain Oolong, known for its smooth, creamy texture and floral undertones.

Winter Flush

  • Characteristics: The winter flush, also known as the "cold weather flush," represents a unique harvesting period characterised by slow growth and dormancy of the tea plants. The leaves harvested during this time exhibit a distinctively subtle and nuanced flavour profile.
  • Seasonality: Winter flush teas are harvested during the colder months, typically between December and February, when the tea plants enter a dormant phase.
  • Regions Where Winter Flush Teas Are Produced: Regions such as Nilgiri in India, parts of China, and select areas in Japan and Taiwan are known for producing winter flush teas.
  • Flavor Profile: Winter flush teas are prized for their delicate, nuanced flavours and subtle aromas. They often possess a smooth, mellow taste with hints of floral and herbal notes, offering a soothing and comforting brew.
  • Notable Winter Flush Teas: Examples of winter flush teas include Nilgiri Frost Tea, appreciated for its delicate aroma and refreshing taste, and Japanese Kukicha, known for its light, nutty flavour and creamy texture.

Comparing Flushes

Each flush, from the delicate first to the rare winter, offers a unique sensory experience that reflects the nuances of its origin and harvesting time. Here's a small comparison.
  • Firstly, the flavour and aroma differences among flushes reveal a rich spectrum of taste profiles. The first flush enchants with its floral delicacy, while the second flush captivates with its full-bodied richness. Autumn flush teas exude a mellow earthiness, while winter flush teas offer a complex interplay of subtle sweetness.
  • Furthermore, differences in the tea leaf's appearance also hint at each flush's characters. From the tender, green leaves of the first flush to the coppery tones of the autumn harvest, the appearance of tea leaves can be unique in each season.
  • The nutritional differences among flushes are also interesting to know. First-flush teas, harvested early in the growing season, are prized for their high levels of antioxidants and vibrant, fresh flavours. Second-flush teas, with their fuller body and complexity, also contain notable antioxidant content. Autumn flush teas, harvested towards the end of the growing season, may exhibit slightly lower antioxidant levels but still offer valuable nutritional properties. Although less studied, winter flush teas are believed to retain essential nutrients, providing a nourishing brew during the colder months.

Tea Culture and Flushes

The significance of tea flushes transcends mere taste and aroma; it is deeply intertwined with the tea culture. In regions such as Darjeeling, India, where tea cultivation is not just an industry but a way of life, flushes hold immense importance. The annual Darjeeling tea festivals celebrate the arrival of each flush. It marks the beginning of a new season of tea harvesting and production.
