Mencía or Jaen is a grape whose origin is associated with the Iberian peninsula. In the past, it was believed that Mencía and Jaen are two separate varieties, but recent research has shown that they are genetically identical.
In Spain, the grape is mostly associated with the Bierzo appellation that is located in the province of León. While for most of its history, Mencía was used in the production of light, somewhat bland table wines, some winemakers have seen the potential to produce more concentrated and better quality varietals with a medium body and good natural acidity.
While the former varietals made from Jaen were mostly of low-quality, better production methods provided aromatic, juicy, and fruity wines with soft tannins, bright acidity, hints of mineral and herbaceous character as well as typical aromas that are reminiscent of red and dark berries.
