Calcu winery is the same as Viña Maquis and is also located in the heart of Colchagua, focused on producing fresh and energetic wines. Viñedos Calcu was originally established in 2000 by the Hurtado family as they bought more vineyards in Colchagua to create wines of a quality similar to their wines from the Maquis vineyard. The vineyards stretch from Colchagua Costa to Colchagua Andes.
Cabernet Sauvignon and Cabernet Franc are top, although Calcu has a range of Bordeaux red and white varieties.
