Take a Collins glass, or any glass that is about 10 to 12 ounces, and fill it up with crushed ice. Over fill it, as the ice will sink when we start adding in the hooch.
Add three ounces of root beer. I won't name names, but I suggest a high quality root beer. This cocktail is all about the spices and you want a soda that is rich and complex.
Now let's add in the booze! Add 1 ounce of each spirit: spiced rum, vanilla vodka, Bourbon, and Tequila. Juice half of an orange, and top it off with a splash of Grand Marnier and a splash of simple syrup. Here's a recipe, just omit the lavender.
Now float the Thai tea on top. You want brewed tea, as in this Thai iced tea recipe, but only the tea. To float it, simply pour the 2 ounces of tea slowly over an upside down spoon.
