The brewing of pear wine comes from accidental discovery. The story of Li Zhongbin's family is recorded in the sequel to Zhou Mi's Homecoming Miscellanies.

It turns out that there is a pear garden in the Li family, and the annual output of pears is several times that of normal years, which is inexhaustible. So, "I put hundreds of pieces in a big urn, covered with mud, and planned to hide it for a long time." Half a year later, the pear in the urn exudes a fragrant bouquet, so I opened the lid and found that the pear has "turned into water, cold and lovely, and Zhan Ran is sweet".

Yamanashi contains sugar, which can be naturally fermented into wine under the action of microorganisms. Artificial pear wine was first brewed in the Song Dynasty.
