-       the king of gluten free drinks is undoubtedly the Gin and tonic. It only has two ingredients, they are both gluten-free and you can indulge as much as you want. 

-       Also excellent options are the Mojito, with rum, lime, mint, sugar and soda

-       Margarita, with tequila, triple sec, lime and agave syrup. In these cases we must be careful: if lime, lemon or mint are fresh then it is fine, otherwise we must make sure that the juice is gluten free. 

To understand which cocktails a celiac can drink, you need to pay close attention to fruit juices because they can contain gluten.
