Ideal for picking up subtle nuances in fine wine, this red wine glass set is scientifically engineered for aged and tannin-rich red wines. Each glass undergoes strict sensory analysis tests, making it the ideal choice for international wine tasting. The shape of the bowl has been designed to enhance or balance the characteristics of a specific type of wine. The stem is strengthened with a patented anti-abrasion treatment that reinforces the glass surface of the stem with titanium, thus offering permanent protection against abrasion and diminishing substantially the fragility of the stem during daily usage. These wine glasses are produced in ultra-clear lead-free crystal glass that offers unbeatable transparency and brilliance for a professional finish as well as providing added resistance to mechanical shocks making them suitable for intensive daily use or use in commercial settings such as restaurants and bars.
