Founded in 1981 by winemaker Johnny Graham, who represents the fifth generation of his family to make wine in the Douro Valley, Churchill's remains a family-owned independent producer. Quinta da Gricha, Churchill's flagship vineyard, is located in the heart of the Cima Corgo in the Douro Valley and features "lagares" dating back to 1852. Benefiting from a north-facing exposure, Quinta da Gricha produces wines with a raw vibrancy and excellent natural acidity.
