A farmer tends to a field of white cabbages in Geispolsheim, eastern France on August 06, 2015. Elevated evening temperatures, strong heatwaves and a lack of precipitation has blocked their growth, resulting in what some farmers call a "white year." The annual cabbage harvest occurs from August until December, and with estimated September precipitation levels, expect output will be 25 to 50% of normal amounts. The Alsace region accounts for 70% of sauerkraut consumed in France, accounting for approximately 60 farms and 700 hectares of land.
