Craft Cocktail ice is made from a special process. True craft cocktail ice starts with highly filtered water like that from an RO filtration system, thus removing any unwanted tastes and smells. Secondly, it goes through a process called directional freezing, which removes the air that causes ice to melt more quickly. Why is this important, you may ask? If you’re buying expensive spirits or paying premium prices for a cocktail at a bar or restaurant, you want that drink to taste as great as possible, from the first sip to the last. Standard ice molds or crushed ice machines simply can’t duplicate the quality of an actual craft cocktail ice production company.
