Soda pop

Soda pop (commonly known as a soft drink or simply pop or soda) was a carbonated beverage that was sweetened by various means. They were so named since they contained no alcohol, as opposed to hard beverages such as whiskey or beer which did contain alcohol. Examples of soda pop were root beer and cola.

Sodas were also known on Miri's planet, where they had been on sale in the Palmerton Cafe in the 1960s. 

In 2267, while poking fun at Pavel Chekov about his beverage of choice, vodka, Montgomery Scott noted to him that where he came from, vodka was called "soda pop". 

Soft drinks such as root beer were among the many beverages available at Quark's.
