Escanyavella
Escanyavella is a white Catalan wine grape variety planted primarily in DOQ Priorat. The name literally translates from Catalan as "old lady strangler" and coughing is often a common reaction to those who eat the raw grapes. While grown in small numbers in Priorat, there are a number of wineries that use it as part of their blends and one that makes a wine completely from the grape although.
It is a thick skinned grape with high acidity and is harvested later than other white varieties.
Despite not being an officially recommended grape for DOQ Priorat wine certification, there has been an effort recently by several cellars in the region to recuperate and revitalize this nearly lost grape.
