The Cojón de Gato grape is a traditional grape variety from Somontano, particularly from the Secastilla area, but it also exists in La Mancha, Aragon and other regions. It has never been among the most valued and, in fact, was used for a long time to give consistency to certain wines, as it is strong and even rough. It has a very long grain, so some believe that its name comes from that form.
Due to its "poor" characteristics and more appropriate to a table grape, its cultivation has remained very limited in the regions of Somontano and La Mancha. The few wines that incorporate that grape inside their wines do it mixing it with other grapes very characteristic like the Shyra and the Merlot.
