The diamond-shaped machine-made cocktail glass is an ideal to give as gift or to enjoy yourself. The steeply rising sides of this glass best benefit the spirits of Martini.The Extreme glasses are named after their extreme contours. The bowls mimic polished diamonds and their wide angles allow plenty of room for the wine to breathe. They are specifically designed to enhance and emphasize the pleasant softness and generally fruity notes of the New World wines.
