The Boutari Winery is easily noted by its Greek white dome and has been producing Greece's wine since 1989. One of the claims to fame is the amazing view of the caldera. Many weddings take place here just for the sheer beauty. The tour includes a look at the winery's grounds, an in-depth look at the wine-making process and of course, the favorite part of the tour, some tasting of their strong, unique, and distinct tasting wines.
FYI: Wines from Santorini, due to the rugged terrain of ancient volcanic subsoil and no rain, are considered "treasures" by some sommeliers of the world.
