Discrimination of advantages and disadvantages of Rosa roxburghii

The appearance of finished Rosa roxburghii in the sun should be yellow-brown, with less surface damage and hard shell. On the contrary, the defective products are dirty, black, with many impurities and excessive color difference.

Observe the color of the soup

Good tea is brewed with boiling water, and the soup color should be yellowish brown, reddish brown, clear and translucent. On the contrary, color turbidity is defective.

sip tea and appraise its flavour and quality

Good Rosa roxburghii tea brewed with boiled water has a unique fragrance, which is sweet and sour, while it is sour when brewed with warm water (warm water can reduce the loss of vitamin C, so it retains more sour taste). The second kind of fruit tea has a strange smell, and the sulfur-smoked Rosa roxburghii Chaze has a bitter feeling.

smell

Grab a handful of loose fruit and put it under your nose for a while. If you can smell the pungent and choking smell, you can be sure that it has been fumigated by sulfur. For the sealed Rosa roxburghii, the first time you open the package, you should immediately smell the unique fragrance of Rosa roxburghii. On the other hand, if there is a strange smell or pungent smell, it is a defective product or smoked sulfur fruit.
