Cantine Florio occupies a long, low building on the coast south of the old town: parallel stone barrel halls more than 150 metres long, filled with thousands of oak casks of Marsala ageing under the wooden roof. The complex is now part of the Illva Saronno group but is still working, and the guided tour is the best of the cellar visits in Marsala.
The visit covers the history of the family — central to 19th-century Sicilian industry and politics — the wine-making process, and a tasting of several styles, from dry Vergine to the dessert Riserva. Reservations are essential; tours run in Italian and English several times a day.
