Root beer is a sweet, carbonated beverage that is traditionally flavored with sassafras or sarsaparilla. It often contains a mix of other herbs, spices, and sweeteners, giving it a unique taste that sets it apart from other soft drinks. Root beer can be enjoyed on its own or used as a base for floats, which combine it with ice cream. Originally, root beer was made at home using various roots and herbs, and it has a long history in North America. Today, it is widely available in bottles and cans, with many brands offering both alcoholic and non-alcoholic versions. Popular brands include A&W and Barq's.
