Old legend says that while St. Martin was visiting a monastery, his donkey enjoyed itself eating the grape vines outside in the vineyard. When the monks perceived the destruction they uttered loud cries believing the vineyard was ruined beyond redemption. But the grape vines recovered, and to the monks’ absolute amazement, the grapes that autumn produced a wine unlike anything they had ever produced before. Today, 1,500 years later, Touraine wine-makers are still growing grapes where St. Martin’s donkey regaled itself on the noble vines.
Tradition also dates the pruning of grape vines to these ravages by St. Martin’s donkey. Since grape harvests after pruning has been done are so superior, vineyard owners have widely adopted this practice.
