Viña Maquis is located in the heart of the Colchagua Valley between the Tinguiririca River and the Chimbarongo Creek. Both waterways act as pathways for coastal breezes that protect the vineyards from frost damage in spring and moderate the warm summers. These breezes have an important effect on lowering the maximum summer temperatures by 2º–3ºC. This affects the characteristics of the grapes and hence the wines by increasing the fresh fruit and floral aromas, making the wines more vibrant on the palate and moderating the alcohol levels.
