After the autumn Tea harvest ends in late October, the Extreme Border Tea Garden, with its increased temperature fluctuations between day and night in the high-altitude region, enters a five-month frost period.
The extended frost period is a unique natural endowment of the highland tea garden.
The Extreme Border tea is grown at an altitude of 1,900 to 2,500 meters, where temperatures tend to be lower, especially during the evenings and early mornings, often dropping below the freezing point.
The lush vegetation surrounding the Extreme Border highland tea garden releases moisture into the air, increasing humidity and providing ample water for frost formation.
The extended frost period plays a decisive role in the superior quality of the Extreme Border highland tea.
Nutrient Accumulation in Tea Plants —
The low temperatures during frosty weather help slow down the growth rate of tea plants and extend their growing season. This also enhances the efficiency of photosynthesis during the growth period, contributing to the formation of richer nutrients in the tea leaves.
Frost also indicates higher air humidity, which benefits the absorption of nutrients from the soil by the tea plant roots. This aids in the accumulation of minerals and organic substances in the tea leaves, enriching their nutritional content.
Taste and Aroma of Tea Leaves —
Frosty weather prompts tea plants to enter dormancy earlier, slowing down their physiological activities. This leads to a relative accumulation of polyphenols, amino acids, and other substances in the tea leaves, affecting their taste and aroma, making them fresher and more fragrant.
Color of Tea Leaves —
Frosty weather may result in a tenderer green coloration of the tea leaves. This color change is often considered an indication of the quality of high-altitude tea, reflecting the slow maturation process in a relatively cooler environment.
How white is the frost, illuminating the highland tea.
Fragrance scatters across heaven and earth, all things are imbued with spring's grace.
