Set at the foot of the Andes is Santiago's most interesting winery. Aquitania works with tiny quantities and sky-high quality.
From Grecia metro station (Línea 4), take bus D07 south from bus stop 6 and get off at the intersection of Av Los Presidentes and Consistorial (you need a Bip! card). Aquitania is 150m south. Note that Viña Cousiño Macul is located only 2km away.
