When José Maria’s grandfather purchased Casa Castillo in 1941, there was already a winery, cellar, and some scattered vineyards on the property dating to the 1870s, established by French refugees fleeing the plight of phylloxera in their native land. In 1985 José and his father began to replant the vineyards and expand them with the goal of making wine on the property. In 1991 they bottled their first commercial vintage.
In selecting the grapes to grow on their land, they chose the indigenous Monastrell to be the primary variety. Native to the region, it was perfectly adapted to the hot, dry climate. Originally Cabernet Sauvignon and Garnacha were selected for the more gravelly soils, while Syrah is grown on more sheltered sites rich in chalk. The largest vineyard, Valle, is a hot, rocky terroir planted exclusively with head-pruned Monastrell. Val Tosca is a sloped vineyard, its white chalky soils gleaming in the sun and planted with ungrafted Syrah that José received from Jean-Louis Chave. On the slope facing Val Tosca is Las Gravas, named for its deep, gravelly soils. Soil is loosely applied here since it resembles nothing more than a pile of rocks. Las Gravas is planted with Monastrell and Garnacha – as José Maria has grafted his Cabernet over to Garnacha, preferring the native variety over the foreign interloper. Finally, there is La Solana, an ungrafted Monastrell vineyard on sandy decomposed limestone that was planted in 1942. La Solana is the source of the scarce Pie Franco, which dwindles in quantity each year because while the soil is resistant to phylloxera, it is not immune. Due to the climate, José Maria can farm his vineyards without needing chemical treatments.
Everything is harvested by hand and brought promptly to the cellar for sorting and fermentation. Fermentations are in stainless steel tanks, concrete vats, or stone lagars. Pigeage is done by foot, and whole clusters are increasingly used – up to 50% in the Pie Franco. Aging follows in concrete, foudre, and 500L French oak demi-muids.
