The inner wall is pasted with hemp paper, coated with pig blood, and then coated with a certain proportion of egg white, beeswax, cooked vegetable oil and other materials, and dried, which is called "wine sea". This kind of storage container is different from other wineries' wine storage containers and has originality.

It is characterized by low cost, large inventory, low wine consumption, good aging, strong leakage resistance and suitable for long-term storage.

The original "wine sea" has different capacities, ranging from 50 kilograms to 5-8 tons. With the popularization of large containers, the compilation capacity of "Nine Seas" has gradually increased, and now there is a 50-ton "Nine Seas".
