Premium is a timeless collection created with the exclusive collaboration of AIS, the Italian association of sommeliers. Each is created with a specific shape and design to complement each type of wine and beverage. This is ideal for serving "bubbles", such as sparkling wines and champagne, as it enhances their large aromatic, and gustatory qualities. The stem of the glass is produced in one piece with the bowl, this is obtained through a particular hot-pulling process of the stem. A very uniform and linear rim is achieved by using a laser beam (rim cutting). This technology improves the quality of the products and is specifically designed to meet the needs of professionals and high-quality wine tasting.
