Under a blanket of snow, the vineyards of France's Côte d'Or region seem asleep in winter. However, it's during this season that their destiny is played out: the vines are pruned and fires are lit to protect them from frost. The coopers make barrels for the next harvest, with a know-how that has earned them international success. Down in the cellars, day after day, oenologists and their keen senses supervise the wine ageing in the barrels.
