The Appellation of Origin Bierzo was created in 1989 and is located in the northwest of the province of León, within the Autonomous Community of Castilla y León. This area has many peculiarities with respect to the rest of denominations of origin of our country.
It is a geoclimatic zone delimited by a crown of mountains, which makes the climate very benign, without cold winds. In summer there is a very extreme climate in the Bierzo, with high temperatures during the day and very low during the night, which makes the grapes mature slowly and have a better color. The annual precipitations are about 721 millimeters and the average temperature 12ºC.
Despite being the smallest area in the vineyard world, this makes El Bierzo one of the competitive advantages that makes its variety so rich. This old vineyards, in spite of giving less quantity of grape, have much more quality. They are vineyards with atomized plots and terrains with slope, from 450 to 800 meters high, with hills oriented to the four cardinal points.
The local varieties that stand out are, in red wines, the Mencía variety (which represents 74.5% of the grapes grown in the production area) and in white wines, the Godello variety. They are varieties that produce very rich, complex and structured wines. Other varieties such as Garnacha Tintorera, Palomino grape and Malvasía are also produced in El Bierzo. These wines are produced by the 77 wineries attached to the Bierzo Designation of Origin.
