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.
