Exploring the Taste of Green Tea: From Varieties to Benefits

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.
