It is impossible to make good wine without healthy, quality grapes. The Arzuaga-Navarro winery boasts over 150 hectares of vineyar. Every Setember, the grape monitoring begins for grapes that are harvested in early October. Selected grapes hand-picked and stored in 15-kg crates that are later transported to the cellar where they undergo the winemaking process. The Castillian weather - hot summer days and humid nights - favors a slow and perfect grape ripeness, resulting in a healthy, and sugary fruit with aromatic acidity.
