Koyle operates in Colchagua Valley, the heart of Chile's Rapel Valley region, where volcanic soils and Mediterranean climate shape distinctive red wines. The winery's portfolio centers on Grenache, Cabernet Franc, Carménère, and Syrah—varieties that thrive in this terroir. Los Lingues Vineyard Cerro Basalto Garnatxa, a pure Grenache expression, and Cerro Basalto Cuartel G2, a Cabernet Franc and Carménère blend, represent the winery's focus on single-vineyard precision. Auma, a structured blend of Syrah, Malbec, Carménère, Cabernet Sauvignon, and Petit Verdot, demonstrates the complexity possible from Colchagua's mineral-rich basalt soils. These wines have been assessed by Decanter, Wine Advocate, Wine Spectator, and Wine Enthusiast, reflecting their standing within the critical conversation around Chilean wine.
