Caliterra sources most of its fruit from its 1000ha Caliterra estate in the Colchaqua Valley.
Caliterra Estate This 1000-hectare estate is situated in the heart of the Colchagua Valley, a sub appellation of the Rapel Valley 150m above sea level and 80km from the coast. 288 hectares of Merlot, Carmenère, Cabernet Sauvignon, Syrah, Malbec and Sangiovese are planted alongside experimental plantings of Petit Verdot, Nebbiolo and Zinfandel. The estate also includes blocks of high-density plantings, which produce the estate's highest-quality grapes.
Hillside plantings have been introduced to reap more of the estate's potential. 32 ha (79 acres) were added to the initial vineyards in 2005 and 46 ha (113.6 acres) of hillside Cabernet Sauvignon, Shiraz, Carmenère and Viognier were added in 2008 for a total of 288 ha (711.1 acres). Rocks are abundant in the estate's medium textured soils that range from clay-loam to sandy-loam, making it possible to obtain wines of different typicities.
For white varieties, grapes are sourced from the Curicó, Leyda and Casablanca Valleys. Caliterra's Teno and Molina Vineyards on the slopes of the Curico Valley benefit from the area's stable climate and soils suitable for producing Sauvignon Blanc and Chardonnay grapes with a high natural acidity. Caliterra's Leyda Vineyards are located only 14 kilometers (8.7 mi) from the Pacific Ocean, where the combination of maritime influence and cool temperatures give birth to extraordinary Sauvignon Blanc grapes. The Santa Marta Vineyard in the Casablanca Valley, one of Chile's most recognized valleys for quality white varieties, is situated only 40 km from the coast and is the source for high end Chardonnay.
