The Jumilla from Casa Castillo is made from younger vines sourced mainly from La Valle vineyard where the soils are silty and the grapes have more of a varietal expression than his rockier vineyards. Once labeled Monastrell José Maria has been incorporating increasing amounts of Garnacha into this wine so that now it is about 80% Monastrell with 20% Garnacha. After a natural fermentation in tank the wine is aged for 8-9 months in neutral 500 liter French oak barrels, and foudres.
