RIO can be drunk with beer.

Cocktails usually use rum, gin, tequila, vodka, whiskey, brandy and other spirits or wine as the base wine, and are supplemented with juice, egg white, bitters, milk, coffee, sugar A mixed drink made by stirring or shaking other auxiliary ingredients, and finally can be garnished with lemon slices, fruits or mint leaves.

RIO cocktails are already mixed alcoholic drinks. If you need to mix liquor and beer, you can just add the required amount and mix evenly, just like adding sugar to coffee. The premise is that the things added do not cause any drug or adverse conflict with those already used, and are harmless to people. This is enough.

Extended information

Cocktails originated in a tavern in Elmsford, New York, in 1776, decorated with cocktail feathers. One day when the tavern was almost sold out of all kinds of drinks, some officers came in and wanted to buy drinks. A waitress named Betsy Flanagan poured all the leftover wine into a large container, plucked a feather from a big rooster, stirred the wine and served it to the guests.

The officers looked at the quality of the wine and couldn't tell what it tasted like, so they asked Betsy. Betsy replied casually: "This is a cocktail!" An officer listened. With this word, he happily toasted and shouted: "Long live the cocktail!" From then on, the name "cocktail" came into being. This is the origin recognized in America.
