This cooperative is the region's largest wine producer and also boasts the country's largest wine cellar, with a capacity of 18 million litres. Since its formation back in 1922, the cooperative has been the driving force behind Goriška Brda's viticulture tradition, and has also taken an active role in promoting the region throughout Slovenia and abroad. Highly educational tours of the cellar along with wine tastings start at only €2.50 per person.
