What’s in 99 Brand Shots?

According to my nerdy calculations based on 1.5oz of 99 proof liquor, about 123 calories come from pure alcohol and each shot is 155 calories total, which means only 22 calories come from something else…If that something else is just added sugar then there’s only like 5g sugar in each airplane bottle (4 calories per gram). What’s in this stuff?? I can’t find the ingredients anywhere…Just curious😂
