Green tea is a type of tea that is not fermented, preserving the green pigments and natural components of the leaves. This is why dried tea leaves are green, and the brewed tea and leaf residues often appear green as well. Green tea enjoys immense popularity worldwide; it is not only an essential part of daily life for Chinese people but is also widely loved by people across different countries. The flavor profile of green tea is characterized by a fresh aroma, refreshing taste, slight bitterness, and sweetness. Different varieties and processing methods of green tea lead to a diverse range of tasting characteristics.

Types of Green Tea

Green tea is the most produced tea category in China, and based on the methods of fixation and drying, it can be categorized into the following types:

  1. Steamed Green Tea: This type is fixed using high-temperature steam, which retains the green color and fresh taste of the leaves. Common steamed green teas include Enshiyulu. It features the characteristics of “green dry leaves, green brewed tea, and green leaf residues,” with a refreshing aroma and smooth taste, though it may carry a strong grassy note.
  2. Pan-Fried Green Tea: This variety is fixed by pan-frying and dried primarily through this method. Depending on the shape of the finished tea, it can be categorized into long-fried, round-fried, and flat-fried, such as West Lake Longjing and Biluochun. It has a rich aroma and the fried green tea is fragrant and delicious, with a bright yellow-green color.
  3. Baked Green Tea: This type is primarily dried through baking, like Huangshan Maofeng and Liuan Guapian. It has a pronounced aroma and a richer taste, with a clear and bright color.
  4. Sun-Dried Green Tea: Fresh leaves are fixed and rolled before being sun-dried, such as Dianqing. The grassy note is quite evident but fades over time, resulting in a richer flavor during the later stages.

What Does Green Tea Taste Like?

Green tea, as an unfermented beverage, retains the original green color and rich natural substances of the tea leaves. The flavor characteristics of green tea are diverse and mainly include the following:

  1. Fresh and Clean: This type of green tea typically has a fresh aroma and a refreshing taste. It is delicate with a high proportion of buds, releasing a crisp sweetness upon sipping, providing a clean and refreshing experience. Fresh and clean green teas may correspond to specific varieties or regions, where the processing preserves more natural substances, resulting in pronounced fresh characteristics. Steamed green tea often exhibits this quality, as the steaming process helps retain the natural nutrients and active compounds in the leaves.
  2. Aroma: The aroma of green tea is not limited to a single note; different varieties and regions exhibit various aromatic characteristics. For instance, pan-fried green teas (like West Lake Longjing and Biluochun) often have notes of beans, chestnuts, and flowers, while steamed green teas (like Japan’s Yulu) might present a fresh seaweed or nori aroma.
  3. Bitterness: The bitterness of tea leaves is closely related to their processing. Improper control of fixation temperature and time can impact the extraction and transformation of bitter compounds. Spring teas generally have lighter bitterness, while summer teas tend to be more bitter due to the higher accumulation of tea polyphenols caused by strong sunlight. High-quality green tea should have a balance of bitterness and freshness, with the bitterness quickly transforming into a pleasant sweetness.
  4. Color: The color of green tea is a crucial quality characteristic. Typically, the dried tea leaves should be emerald green, the brewed tea bright green, and the leaf residues should be tender green. The color is influenced not only by the contained substances but also by the processing methods and storage conditions. For example, prolonged exposure to oxygen and light may lead to the degradation of chlorophyll and oxidation of catechins, impacting the tea’s color.
  5. Leaf Residues: The leaf residues should be bright green, indicating freshness and tenderness. They should be soft and elastic, reflecting the quality of the leaves. Leaf residues should remain intact with clear veins and minimal breakage. They should emit the distinctive fresh aroma of green tea; any off-odors may indicate quality issues. The shape of the leaf residues should align with specific green tea characteristics, such as the “one flag, one gun” shape of Longjing tea.

Factors Affecting the Taste of Green Tea

The taste of green tea is influenced by various factors, including the growing environment, production methods, and storage and brewing techniques.

1. Varieties

  • Sencha: The process of making Sencha involves roasting and grinding the tea leaves into powder, followed by boiling water at a specific temperature to extract the essence of the leaves.
  • Matcha: Matcha is a special powdered green tea made from shade-grown fresh leaves that are steamed, dried, and then ground into a fine powder. It contains beneficial components such as tea polyphenols, caffeine, chlorophyll, and proteins.
  • Gyokuro: Gyokuro is a traditional steamed green tea characterized by its tightly rolled, needle-like leaves with a prominent white fuzz, deep green color, clear and bright infusion, fresh aroma, smooth taste, and tender green leaf residues.

2. Location

  • China: The flavor profile of Chinese green tea typically features a bright, refreshing taste, complex aromas, and a pleasant aftertaste. It tends to develop aroma and flavor through pan-frying or baking.

How to Avoid Bitterness in Green Tea

To prevent bitterness in green tea, it is essential to control the brewing temperature, tea quantity, and steeping time. Here are some specific tips:

  1. Use Suitable Teaware: Using breathable teaware, such as glass or ceramic cups, can help regulate water temperature and prevent the tea from becoming too hot and bitter. Additionally, using wide-mouthed teapots allows for better heat dissipation, reducing bitterness.
  2. Freshness of Tea Leaves: Choose fresh green tea, as freshness directly affects aroma and taste. Store tea away from high temperatures, humidity, and odors to maintain its quality.
  3. Adjust Tea Quantity: The amount of tea used also influences the flavor of the infusion. Using too much tea can make it bitter. A general recommendation is a tea-to-water ratio of 1:50, meaning 1 gram of tea per 50 milliliters of water. Adjust according to personal taste.
  4. Control Water Temperature: Green tea is delicate and should not be brewed with boiling water, as this can extract excessive bitterness. It is recommended to brew with water at 70-85°C to better preserve the fresh flavor and aroma while minimizing bitterness.
  5. Pay Attention to Water Quality: The quality of water can affect the taste of the infusion. Using purified or spring water for brewing green tea can enhance the flavor, as tap water may contain chlorine or other chemicals that can alter the taste.
  6. Control Brewing Time: Avoid steeping for too long; the first infusion should be consumed within 1-3 minutes. As you brew more times, you can extend the steeping time slightly. Quick infusions can reduce the extraction of bitter components, keeping the tea fresh.
  7. Use a High Pour Technique: Pouring water quickly increases the surface area of the tea leaves in contact with the water, helping to better release the aroma of green tea.
