Chillin’ Brew’s™ freezing point of 28°F makes it uniquely suited for keeping any beverage at its coldest point possible. With the addition of Chillin’ Brew™ to a cooler, the contents don’t have to be just cold, they can be colder than ice! Chillin’ Brew™ has been shown to keep coolers under 32°F for days! 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% longer than an equal weight of ice would last alone. For your convenience, 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!
