Alcohol itself is a source of calories. The number of calories in a drink is primarily determined by the alcohol content, rather than the amount of sugar that is added to the drink. That's because alcohol is more calorie dense than carbohydrates.
Alcohol is a source of "empty calories," which means it is calorie dense but does not provide other nutrients, like vitamin and minerals.
This table shows the relative number of calories (calories per gram)
coming from each macro-nutrient group.

So which drinks should have the most calories? Drinks with high alcohol content, larger sizes, and additional sugar and syrup mixers.

Alcohol in the bloodstream causes the pituitary gland in the brain to block the creation of vasopressin. This causes the kidneys to send water directly to the bladder rather than reabsorbing filtered water into the bloodstream. This diuretic effect increases as the blood alcohol content increases, and can lead to dehydration - a contributing factor to hangovers.
Studies have shown that drinking 250 mL of alcoholic beverage causes the body to expel between 800-1000 mL. This means that the body is releasing more than just the liquid being consumed. One way to decrease the effect is to keep your BAC low, and alternate between alcoholic and non-alcoholic drinks (preferably water).
