The Denominacion de Origen (DO) Manchuela, or wine appellation, is located in eastern La Mancha, close to the beautiful town of Cuenca.  This is one of the newest DOs in Spain, formed from the natural break-up of huge La Mancha into more coherent appellations.  Much of the production is still mediocre, but there are more interesting wines being made these days. 
One of the pioneers in the area is Finca Sandoval, a winery which makes consistently excellent wines in a challengingly hot climate. The winery was founded in 1998 and is the personal project of a well known Spanish wine critic, Victor de la Serna.  There search for quality includes traditional open-top fermentation vats with manual punch down…the wines are neither fined nor filtered.  Most of the grapes are local:  Bobal, Monastrell, and Garnacha, but they also have some great Syrah, using clones from Chateauneuf-du-Pape.  There are only two wines:  Salia is a great entry-level option at only about 12 euros.
