D.O.C. stands for "denominazione di origine controllata," which refers to the controlled designation of origin for Italian quality wine. Committed to quality, the eponymous tasting glass collection by Luigi Bormioli Italy was developed in collaboration with professional sommeliers. The glasses are very thin-walled and slightly tapered at the top, allowing for better assessment of the wine's consistency when swirling and optimal release of its aroma. Thanks to Luigi Bormioli Italy's sparkx effect, the glasses are particularly clear, providing an almost completely unobstructed view of the wine's color.
