In 2005 the Tillman Family planted Alta Colina Vineyard at an elevation of 1600’-1800’ on Adelaida Rd. The soils are a combination of Gazos and Santa Lucia which are silicious shaly loams and have a lower pH than limestone soils. This soil chemistry creates wines with less acidity and more richness and texture. The Mourvedre planted on top of the hill is clone 369, which tends to be more brooding with lots of dark fruit qualities. Alta Colina is always one of the first vineyards to see bud break, flowering, and veraison due to its high elevation.
