1ozJose Cuervo Tequila
In a tall beer glass (20 oz.) mix the OJ, beer, and tequilla (in that order). NO ICE, but make sure the beer and OJ is cold. then add in the grenadine.
When the sunrise effect takes place due to the layers you now chug the whole glass. You can actually taste the different liquors go by and by the time the bottom hits, the grenadine makes it all go down nice.
The record for the most Nuclear Sunrises consumed in an evening is 11.
PS The larger the glass the better. (just don’t forget to put MORE of everything in.
