A picture taken on November 25, 2011 in Voiron, shows the biggest liqueurs' cave in the world with barrels of Chartreuse, an old French liqueur. The liqueur is named after the Monks' Grande Chartreuse monastery, located in the Chartreuse Mountains in the general region of Grenoble in France. The liqueur is produced in a factory in the nearby town of Voiron (Isère). Chartreuse gives its name to the color chartreuse. It is one of the handful of liquors that continues to age and improve in the bottle. AFP PHOTO / JEAN-PIERRE CLATOT (Photo credit should read JEAN-PIERRE CLATOT/AFP/Getty Images)
