This is what good wine from the Jaén Blanco grape tastes like

The Jaén Blanco is a relatively unknown grape variety that has been cultivated in Spain and Portugal for many centuries. You rarely see wines made from it. Yet, it's an important grape, as it has developed a wide variety of descendants in this region over the centuries.

In Spain, it's called Jaén Blanco, Cayetana Blanca, or Pardina; in Portugal, it's called Mourisco Branco. All are genetically the same ancient grape. Nowadays, it's mainly found in the Spanish regions of Extremadura and Castile. Elsewhere, it's still occasionally distilled.

It's not entirely clear where this ancient grape originated. It could be near the southern Spanish town of the same name. There are also indications that it originated in Alentejo, southern Portugal. Over the centuries, several (spontaneous) crossbreeds with other grape varieties have occurred. Among others, Gouveio, Síria, Antão Vaz, and Castelão all descend from Jaén Blanco.
