The Coupette is designed for drinks that include a small juice content or mixer as well as alcohol. As a result, this glass holds a slightly larger capacity than the Cocktail glass. The phrase Coupette originates from the French 'coupe', which means bowl or goblet. Blocked ice is not normally used in this glass, though it is popular for frozen drinks where ingredients are mixed in a blender with ice and served as a sorbet-like mass. This product is made of clear crystal glass. SPIEGELAU has created the perfect series for those who want to raise the bar in their lives. With help from internationally renowned mixologist Stephan Hinz, the Perfect Serve Collection bar glasses are expertly sized to accommodate every cocktail, whether classic, inventive, or whimsical, so now you too can bring a little bit of bar culture into your home. This product is machine-made. Due to the manufacturing process small tolerances in the measurements are possible.
