In a cocktail shaker combine the vodka and citrus juices and shake well.
Fill two tall collins glasses with ice layering a few lemon and lime slices with the ice. Divide the vodka between the glasses and then top each glass with coconut water.
Stir slightly and serve
Notes
This cocktail is awesome with just lemons or just limes or even a little orange juice/orange slices. If you prefer sweeter - add in a little simple syrup - about one teaspoon to each cocktail. This cocktail is also really good with 1800 coconut tequila, which I might even prefer over the vodka.Simple Syrup is a 1:1 sugar to water mix. Heated up until the sugar is dissolved. I make a batch a few times a year and keep in a jar in my fridge. Its great to have on hand for cocktails, lemonades etc.
