No one wants a summer romance to end, especially when it's a match up of frozen watermelon cubes -- sweet, juicy and pink -- whirled in a blender with sweet rosé wine.   

Simplicity is the great thing about the Moscow Mule cocktail recipe -- just three ingredients: lime juice, vodka and ginger beer. The spicy drink with a hint of tang over lots of crushed ice is easy to make and open to all sorts of variations like adding refreshing white wine.

Looking for the perfect summer drink? A little sweet, a little tart and full of light, fizzy fun. Meet the Ruby Sweet Caroline, the official cocktail of summer.
