National Beverage Day traces to 1921, when an unnamed contributor to The Re-Ly-On Bottler, a trade magazine for beverage producers, encouraged bottlers to promote the purity and wholesomeness of carbonated drinks. By 1925, the American Bottlers of Carbonated Beverages declared it an annual event.
From fizzy water to a $170 billion industry
The scientific foundation was laid in 1767, when English chemist Joseph Priestley discovered that water could be infused with carbon dioxide by suspending it above a beer vat. Johann Jacob Schweppe commercialized the process in 1783. By the late 19th century, pharmacist-inventors were adding flavored syrups to carbonated water — Coca-Cola in 1886, Pepsi-Cola in 1893.
Prohibition (1920-1933) transformed the non-alcoholic beverage industry. With alcohol banned, Americans turned to soft drinks, coffee, and tea. Coca-Cola's market position strengthened dramatically during this period, and the habit of reaching for a carbonated drink instead of a beer outlasted the 18th Amendment.
