So, what are the factors that form the unique quality style of Anxi Tieguanyin? Combined with the research results of some experts and scholars, let’s talk about some superficial views. 1.

This unique geographical environment creates a suitable ecological environment for the growth of Tieguanyin tea trees. 1. Climate conditions in Anxi Tieguanyin: Climate conditions are one of the main factors affecting the growth of tea trees and the quality of tea products. Most of the Tieguanyin tea gardens in our county are located between 500 and 1,000 meters above sea level.

They have relatively low, high and variable temperatures. The climate characteristics of clouds and mists provide a unique natural environment for the formation of the excellent quality of Tieguanyin. The relative climate results in slow growth of buds and leaves, which is conducive to the synthesis of soluble nitrogen compounds, amino acids and aromatic substances in shoot tissues. Alpine tea gardens have a lot of diffuse light. It is also conducive to the synthesis of aromatic substances. At the same time, the large temperature difference between day and night is conducive to the accumulation of photosynthetic products, which increases the content of sugar compounds, proteins, amino acids and vitamins, thus forming the unique aroma of Anxi Tieguanyin with a high and long fragrance and a rich and sweet taste. quality.
