No.1 grade tea is truly "antique tea", which generally refers to the tea produced by private tea brands from the late Qing Dynasty to the early liberation, so the naming method is also named after tea brands. At that time, the main tea brands were Gan Lizhen, Song Pin, Yang Pin, Tongqing, Tongxing, Tongchang and Jingchang. Nowadays, there are few old teas left over from these tea brands on the market.
The tea cake of No.1 grade tea is a "naked cake", which has no paper packaging like that of later grade tea. It is usually just a piece of sticky rice paper with the name printed on it and pressed in the pressed tea, that is, "flying inside".
"Neifei" is an important identification trademark of grade tea. People often say "red label" and "blue label", etc., in fact, it refers to the red flying and the blue flying. Generally, the "red label" is the first choice, followed by the "blue label".
It's not uncommon that the price of No.1 grade tea is more than one million yuan per cake.
