The Active Cooler Whiskey from Vacu Vin cools your whiskey to the ideal serving temperature, without losing any of its complex flavors. As the cooler does not make use of ice, the whisky won’t be diluted. Compared to Whiskey Stones, the cooler keeps your whiskey at the right temperature longer. The flexible silicone design is inspired by the elegant looks of a rocks glass, which accommodates most size whiskey glasses. It also prevents your glass from getting warm when holding it in your hand. The reusable Whiskey Cooler takes up little space in your freezer.
