The Bierzo DO has a special microclimate, which is optimal for viticulture. The low altitude means that the grape harvest is usually about one month earlier than in Castile, with the minimum in winter of 3.5 ºC and maximum in summer of 24 ºC. The average annual rainfall is just over 700 mm, and the vines receive about 2,200 hours of sunshine per annum.
