I'll check with our Salesmanager for Spain and see where exactly folks in Spain can buy it. I'll answer your email concerning the other info you needed sometime next week, going to be quite busy after the Vinexpo. I'll try to be quick about it.
Quite interesting the whole article but I would like to clarify a few (2) things. Cariñena variety is the "Mazuela", it's the common farmer name given to the grape by the folks of Cariñena.
Concerning the Bodegas Ignacio Marín (not available in US)... we have the "Barón de Lajoyosa Gran Reserva" but not very extended around the US, matter of fact it's one of the wines I gave you to taste along with the MARIN OLD VINE GARNACHA.
Just a quick observation, in September (mid month, I'll double check exactly when) in Cariñena the main holidays are the FIESTA DE LA VENDIMIA, and we have an OPEN HOUSE for everyone to come visit the bodega, taste our wines and come to enjoy the town holidays where we have the main fountain pouring out wine for everyone.
