Pu-erh tea soup color is slightly turbid for eight reasons:

1. Pouring water too vigorously or too quickly when brewing tea.

2. Tea in a changing phase (sun-dried green tea aged 1-2 years, baked green tea around 4 years).

3. Newly made ripe Pu-erh tea brewed immediately.

4. Using overly mixed tea leaves (rainy season material).

5. Mold contamination or poor storage ventilation.

6. An abundance of fine hairs on the tea leaves, i.e., more visible fuzz, common in spring tea buds.

7. Tea leaves broken too finely, or too many broken tea fragments added.

8. Higher quality Pu-erh tea is more likely to exhibit turbidity after cooling.
