Sencha Tea

Sencha tea is a type of Japanese green tea that is widely appreciated for its balance of sweetness and astringency. It is made from the first or second flush of Camellia sinensis leaves, which are the same leaves used to make many other types of teas.

After harvesting, these leaves undergo minimal processing. Unlike other green teas, Sencha leaves are steamed, a method that preserves their green color and fresh flavor. This steaming process typically lasts between 15 to 45 seconds and prevents oxidation, thus maintaining the tea’s vibrant color and delicate, vegetal taste.

The steamed leaves are then rolled, shaped, and dried, which creates the needle-like appearance characteristic of Sencha. The quality of Sencha can vary significantly, often reflected by its color—bright green being a typical indicator of higher quality. Below is a brief outline of Sencha’s key characteristics:

  • Origin: Japan
  • Processing: Steamed, Rolled, and Dried
  • Flavor Profile:
    • Sweetness
    • Astringency
    • Vegetal Notes
    • Oceanic Undertones

Indulging in a cup of Sencha, you'll taste the nuanced flavor resulting from this meticulous process. You're likely to experience a complex blend of flavors, encapsulating earthy notes with a pleasing, lively finish.

When brewing, water temperature and steeping time are crucial to extract the perfect balance of flavors. Hot, but not boiling, water is recommended, and steeping typically lasts for one to two minutes. This precise preparation yields a refreshing cup of Sencha tea, emblematic of Japan's tea culture and tradition.

History of Sencha Tea

Originating in the 17th century, sencha is a Japanese green tea that you might recognize by its distinctive, needle-shaped leaves. Unlike matcha, which is ground into a powder, sencha leaves are infused to create a clear, green-hued tea.

The method of steaming fresh tea leaves to prevent oxidation was brought to Japan by Sō Shitsu VI, an influential tea master. This introduced you to the unique taste profile of sencha: a balance of sweetness and astringency.

By the 18th century, as cultivation techniques improved, sencha became accessible to the general public. This growth in popularity made it an integral part of your daily life in Japan, enjoyed for its refreshing flavor and health benefits.

Key Milestones:

  • 17th Century: Introduction of sencha by tea master Sō Shitsu VI
  • 18th Century: Widespread popularity among the masses
  • Today: Presence in global markets as a premium healthy beverage

Your understanding of sencha tea would be incomplete without acknowledging Nagatani Soen, often credited with perfecting the sencha processing method in the 1730s, influencing how you enjoy sencha today. His innovation involved steaming, rolling, and drying the leaves in a way that preserves their color and taste.

The tale of sencha is one of evolution and adaptability, grounded in tradition yet embraced in modernity. With each sip, you're part of a historical journey from past to present.

Production Process

The production process of sencha tea involves a series of meticulous steps, each critical for achieving its distinctive taste and quality.


You'll find that sencha tea plants thrive in well-drained, fertile soil. These plants are often grown in full sun but can be shaded for a period before harvesting to alter the flavor profile, resulting in a milder, sweeter tea.


The harvesting of sencha leaves typically occurs in the first or second flush, when the leaves are young and tender. The precise timing of the harvest is crucial, as it influences the final taste and aroma of the tea.

  • First Flush: usually in late April to early May
  • Second Flush: often in June or July


Immediately after harvesting, sencha leaves undergo steaming for about 15 to 20 seconds. This quick process halts oxidation, preserving the green color and fresh flavor.

  • Purpose: to stop oxidation, maintain color
  • Duration: short, precise timing


Post-steaming, the leaves are rolled. This step shapes the sencha leaves into their distinctive slender, needle-like form and also helps in developing flavor.

  • Technique: gentle and precise
  • Outcome: needle-like leaves, enhanced flavor


Rolling is followed by drying, where the moisture content of the leaves is reduced, which safeguards the tea from deterioration and locks in the flavor.

  • Objective: reduce moisture content
  • Method: carefully controlled drying process


Finally, the dried leaves are sorted to ensure uniformity and quality. This includes removing any stems, broken pieces, and varying leaf sizes.

  • Criteria: size, shape, and quality
  • Tools Used: sieves and sorting machines

By systematically following these steps, your sencha tea is transformed from fresh, vibrant leaves to the final product ready for brewing.

Types of Sencha Tea

Sencha tea, a popular Japanese green tea, comes in various types distinguished by processing techniques, steaming time, and harvest periods. Your experience with sencha can vary significantly depending on these factors.


Shincha is the first flush tea of the season, celebrated for its freshness and vibrancy. Harvested in early spring, the young leaves contain a higher concentration of nutrients and sweetness due to the winter dormancy period.


Asamushi, also known as light-steamed sencha, undergoes a short steaming process, typically for about 30 seconds. This results in a more delicate flavor and a light green hue. You'll find it has a subtle sweetness with a crisp finish.


Chumushi is medium-steamed sencha, a balance between Asamushi and Fukamushi. With steaming times around one minute, Chumushi retains a rich color and a fuller body than Asamushi, with a moderating balance of sweetness and astringency in its profile.


Fukamushi refers to deep-steamed sencha and is steamed for double the time of Chumushi, sometimes more. The extended steaming breaks down leaf structure, which in turn leads to a cloudier tea with a deeper green color and a more robust flavor. Your palette will discern a pronounced sweetness with reduced bitterness.

Brewing Sencha Tea

To achieve the perfect cup of sencha tea, precise control over water temperature, steeping time, and choosing the right utensils is vital.

Water Temperature

For sencha, the ideal water temperature is between 70-80°C (158-176°F). Excessively hot water will extract too many tannins, resulting in a bitter taste, while too cool water won't release the full range of flavors.

  • 70°C (158°F): a smoother, milder flavor
  • 80°C (176°F): a more robust flavor

Steeping Time

Steeping sencha requires attention to timing to balance flavor and astringency. Use the following guide:

  • 1st infusion: steep for 1 minute
  • 2nd infusion: steep for 20-30 seconds
  • Additional infusions: slightly increase the steeping time


Selecting the proper utensils will enhance your sencha brewing experience.

  • Teapot: A small, Japanese kyusu teapot is recommended for efficient tea leaf movement.
  • Cups: Small, handle-less cups help appreciate the tea's temperature and aroma.
  • Measuring scoop: A bamboo scoop, or shashaku, ensures consistent tea measurement.
