Peasants' Wine was served at the Teahouse in Tien's Landing by Steeper Yanru. One bowl of Peasants' Wine was worth only a third of a bowl of Imperial Seasoned Spirits. This wine was preferred by Three Sheets Dutong.
The Player can use this wine in game to make Three Sheets Dutong drunk and thus be able to get a confession. A combination of two bowls of Imperial Seasoned Spirits and one bowl of Peasants' Wine does the trick. This helps complete Quest: Old Mother Kwan.
