With half of Spanish wines coming from these regions, it would be remiss to ignore them, but they have suffered from a poor reputation over the years. Most of the wine goes through co-operatives and is sold on cheaply to be drunk immediately.
The main grape variety is Airen in La Mancha and it is nothing to write home about.
Wines from Valdepenas tend to be of much better quality and made from the Tempranillo grape. They therefore age well and benefit from a few months in oak barrels to give them a more rounded and smoky flavour.
