The key to aging tea lies in the transformation of specific tea varieties, with significant variations in transformation rates under different storage conditions,
In Kunming, where the average annual temperature is 15-17 degrees Celsius and the average humidity ranges from 40-60%, tea leaves undergo slower transformation. It typically takes about 15 years for them to develop the characteristics of aged tea.
Represented by the Pearl River Delta region in Guangdong, where the annual average temperature reaches 20-25°C, summer temperatures often exceed 35°C, and the relative humidity remains at 70%-80% year-round, surpassing 90% during the rainy or plum rain season. Under such high temperature and humidity conditions, tea stored for over 10 years exhibits distinct aging characteristics: the stimulating effect fades, leaving behind a pronounced aged aroma and a mellow, harmonious taste profile.

The most typical characteristic of aged tea's aroma is its mellow, aged fragrance, also known as "old-aged" scent, which includes some unique notes such as medicinal and camphor-like aromas.
The stimulating effect of the tea liquor gradually diminishes as the storage time increases, as the tea polyphenols in the leaves undergo extensive transformation, resulting in a mellower and smoother tea liquor.
During the long-term aging process, substances such as tea polysaccharides and tea pigments undergo significant transformation, resulting in a richer taste of the tea infusion. Additionally, the throat resonance deepens and the breathy sensation intensifies. Beyond this, the fullness and weightiness of the tea infusion also improve with age, leading to a more harmonious and stable overall performance.
These changes not only reflect the charm of natural tea aging but also enhance the unique drinking value of aged tea.
