Before dawn, rows of candles flickered on the icy vines of Chablis. When the sun rises, the ice crystals shine through the vines. Some vintners have tried to warm the vines with electrical wires or spray the vines with water to prevent frost. This water forms a thin layer of ice first, ensuring that the temperature of the vine stays near freezing, but doesn't drop too much.
