The Denomination of Origin Bierzo is a small region in the western part of the province Castilla and Leon in Spain. Famous for the use of the native Mencia variety. The name of the region was derived from the pre-Roman city Bergidum. The Romans already developed not only agriculture in this region, but also planted the first vines of Vitis Vinifera. With the growth of the monasteries - especially Cistercian - in the middle ages, viticulture also grew a lot. Initially, the wines were sold to the regions of Galicia and Asturias. Bierzo suffered much from the plague of phylloxera in the 19th century, but some wineries - such as Luzdivina Amigo - still have some plots with native pre-phylloxera vines. The Denomination of Origin Bierzo was officially recognized in 1989.
The annual average temperature is only 12 ° C, With minimum in the winter of 3.5 ° C and maximum in the summer of 24 ° C. The vines receive about 2,200 hours of sunshine per year, and there is about 700mm of rain a year.
