Entertaining doesn't get simpler than filling a cooler with beer.

But if you'd like to more options with minimal hassle, consider the squeeze bottle.

We've put together three mixtures that are great when they're added to cold beer. Make them ahead of time and label the bottles accordingly, then let guests create their own beer concoctions by squirting one of the mixtures directly into their beer cans. Bottoms up!

Mixer One
In the squeeze bottle: equal parts fresh lime juice and Worcestershire sauce
In the can: lager or pale ale
To serve: Take a hearty sip, then squeeze in a small amount of the mixer; add one dash of hot sauce. Sprinkle the can's rim with salt, then serve.

Mixer Two
In the squeeze bottle: equal parts fresh orange juice and Campari
In the can: IPA
To serve: Take a hearty sip, then squeeze a small amount of the mixer into the can and serve.

Mixer Three
In the squeeze bottle: equal parts soy sauce and fresh ginger juice
In the can: wheat beer
