Whether you call it soda or pop, you’re probably familiar with Coke, Pepsi, and Dr. Pepper. While these three sodas seem to dominate discussions about soft drinks, you might be surprised to know that none of these are the oldest soda in the world; instead, that distinction goes to a lesser-known beverage.

The oldest soft drink in the world was created by Jacob Schweppe, who founded Schweppes in 1783 in Switzerland. Schweppe refined the carbonation of mineral water and patented the process, before moving the company to London in 1792, where it became the official drink of the Great Exhibition of 1851.

Schweppes has roots in ginger ale, tonic water, and club soda, and the company stays true to those roots today even though it is now owned by the Dr. Pepper Snapple Group. While Schweppes was the first soda, it wasn’t until Coca-Cola that carbonated drinks became popularized as a casual beverage rather than a medicinal tonic.
