Arctic Ice Chillin&'; Brew was specifically designed with the beer drinker in mind, but is excellent for cooling anything you want kept cold. Chillin&'; Brew&';s freezing point of 28 degrees Fahrenheit makes it uniquely suited for keeping beer or any other beverage at its coldest point possible. Chillin&'; Brew is reusable for a lifetime, making it a very economical choice for years of "colder than ice" coolers. Chillin&'; Brew can also be used with ice to keep ice frozen up to 50 percent longer than an equal weight of ice would last alone. Chillin&'; Brew should be stored in a freezer for ease of access and will re-freeze in about 6-8 hours. Chillin&'; Brew panels are also top-rack dishwasher safe.
