the Luna Negra Cocktail

Every so often I come up with cocktails. The Luna Negra is a drink I made last spring, it's really best as a spring or summer drink but it can be enjoyed any time. 

It was inspired by a song of struggle by Los Cojolites. The Luna Negra recipe is made of everyday things but is dense with mystery.

How to make the Luna Negra:
stir in Old Fashioned glass with ice
2 oz 100% agave silver tequila
Juice from one quarter a lime
3 dashes orange bitters
root beer (w real sugar)
