Bad wine

Bad wine is obtained when failing an attempt to make wine by using grapes on a jug of water at level 35 cooking. It becomes impossible to fail this process at level 70 cooking. The player will not receive cooking experience if the unfermented [sic] wine turns into bad wine. Bad wine could be considered a useless item if the player does not want to do the wine trick. Consuming the wine only has the negative effects of the good wine and empties the jug.
