Mingna Baichuan is a tea brand from Yunnan, with a rich variety of green tea products and unique quality characteristics. Here is a detailed introduction:
Origin and raw materials: Mingna Baichuan green tea is mainly produced in high-altitude areas such as Pu'er and Lincang in Yunnan. These areas are shrouded in clouds and mist, with suitable climate and superior growth environment for tea trees. The quality of tea raw materials is high, and the tender buds of Mingqian tea trees are often used. For example, the premium Biluochun tea is made with over 95% of single bud tips, ensuring the freshness and nutritional content of the tea.
Production process: Using traditional techniques combined with modern technology, strict roasting, rolling, baking and other processes are carried out to preserve the original flavor of tea leaves, while improving production efficiency and quality stability.
Product types and characteristics: There are multiple categories, such as premium silver silk, with tender and delicate buds, good aroma, and a sweet taste upon entry. Special grade Biluochun has a clear green and yellow soup, a strong tea flavor, a quick recovery of sweetness and saliva, and a high tolerance for soaking. Green pine needles are Yunnan large leaf green tea, with tender buds, fresh, refreshing, sweet, and long-lasting soaking.
Taste and aroma: The tea soup is mostly light yellow and bright in color, with a large amount of tea leaves suspended in it. The aroma is mainly characterized by the fragrance of tea leaves and tender notes, some of which have chestnut and bean aromas. The taste is fresh and refreshing, but some products may have a strong astringency, such as the 2017 single bud silver silk. Although the tea soup is sweet and refreshing, the tongue surface is noticeably astringent.
Packaging and Specifications: There are various forms of packaging, including boxed and bulk, with different options such as 250g and 500g to meet the needs of different consumers.
