Longjing tea, also known as Lion's Dragon Well, is a traditional Chinese tea, mainly produced in the West Lake Longjing Village in Hangzhou, Zhejiang Province. Longjing tea is customarily categorized into two types: green tea and yellow tea, while yellow tea belongs to a relatively small category in Longjing tea.

Yellow Longjing tea is a yellowish-brown color resulting from the fermentation of tea leaves, while green Longjing tea is unfermented green tea. The two teas have slightly different production processes and flavors.

Overall, yellow Longjing tea is more stable than green Longjing tea, with a softer taste, mellower flavor, and long-lasting aroma. Yellow Longjing tea tends to have more aging potential and lasts longer. However, yellow Longjing tea is produced in smaller quantities and is usually priced higher.

Green Longjing tea is known for its fresh aroma, freshness, and more refreshing and lighter taste, with tender green color and mellow flavor. Green Longjing tea is usually more suitable for fresh drinking. In addition, green Longjing tea contains higher levels of caffeine and tannins, which have some refreshing and digestive properties. Green Longjing tea is produced in larger quantities and is relatively more affordable.

When choosing between yellow or green Longjing tea, you can choose according to your personal taste preference and needs. If you prefer a softer taste and higher aging potential, you can choose yellow Longjing tea. If you prefer a tea with a more refreshing taste and a relatively lower price, you can choose a green Longjing tea. Whichever you choose, you will be able to taste the unique flavor of Longjing tea.
