If you want to freeze soft drinks for use at a later date, it is better to freeze juice such as orange, apple, tomato, or mixed fruit juices. Other soft drinks which are better for freezing include lemon or peach iced tea, and flavored water. They will all taste the same as before you put them in the freezer. Non-carbonated lemonade is also a good choice as are herbal infusions and coconut water. Many of these are healthier than carbonated drinks.
