The wine cellars of Cricova are the second largest wine cellars in Moldova. (The largest wine cellar in Moldova belongs to Milestii Mici, recorded by the Guiness Book of World Records as having the world’s largest collection of quality wines, 1.5 million bottles). The tunnels under Cricova have existed since the 15th century, when limestone was dug out to help build Moldova’s captial, Chisinau. During the 1950′s, the tunnels were converted into an underground wine emporium. Half of the roadways are used for wine storage. The roads are named by the wines they store. This “wine city” has its warehouses, tasting rooms and other facilities underground. It goes down to 100 metres (330 ft) below ground and holds 1.25 million bottles; with the oldest wine dates back to 1902. Cricova is one of the very few wineries in the world that produce sparkling wines in accordance with the classical French method.
