Pu-erh tea cakes are traditionally made in a standard size of 357 grams, but why?
The weight and packaging of pu-erh tea cakes are based on a measurement unit used in China, known as ‘jin’ (斤). One jin is equal to 500 grams. Pu-erh tea cakes are traditionally pressed into cakes that weigh 357 grams each, and they are often packed in sets of 7 cakes, resulting in a total weight of 2499 grams or 2.5 kilograms. This is equivalent to 5 jin, which is a round number that is easy to count during trade.
