Koyle Costa Cuarzo Colchagua Costa Sauvignon Blanc 2021

Koyle is the new project of the Undurraga family (Max, accounts, Alfonso, sales and Cristóbal, viticulture and winemaking), who have sold the company that bears their name and bought a lovely estate near Los Lingues, called Viña Koyle, in Alto Colchagua to make, principally, fine red wines.

They planted 50 ha in 2006/7 (cabernet sauvignon, carmenère, syrah, malbec, petit verdot, mourvèdre, tempranillo) and a further 30 ha in 2010 (cabernet franc, merlot, carignan, grenache, sangiovese and petit syrah) totalling thirteen varieties. The vineyards are at the base of some hills at 400-550m altitude in quite a windy situation, particularly in summer, where the maximum average temperature in the hottest month is about 26ºC. Annual rainfall is between 500-700mm and may allow some vineyard blocks to be “dry farmed” once the young vines have established deep roots. The soil is red clay over friable granite soils.

The vineyard faces north-west and is divided into three terraces. The bottom terrace has more clay and alluvial soils, while the middle and upper ones have decreasing proportions of clay and increasing amounts of stones and friable granite. The altitude gives a 2ºC difference in temperature.

The vineyard is currently undergoing a transformation to biodynamic viticulture. There is huge potential to make lovely wines here; Cristóbal, who lives in a house built on the property, has a real feeling for vineyards and viticulture and is also a very experienced winemaker, having worked in Australia at Rosemount with Phillip Shaw, in Bordeaux at Château Margaux with Paul Pontallier and in Mendoza for Kaiken with Aurelio Montes. The early stars have been carmenère and mourvèdre. One can sense great quality potential here.
