Liquor Beer Calories

What has more calories and is considered more fattening, beer or hard liquor?
I've heard arguments for both. Some say the beer has yeast and is considered high in carbohydrates, while others say hard liquor is more concentrated and has more sugar than beer. What is more fattening?
A general rule for beer and liquor, if you can see through it, then it is lower in calories, if you can not see through it, then it is high in calories. Example: Coors Light and Vodka – Light Amber in calories / porter / stout and Bourbon, Whisky & Spirits – High-calorie Fruity Anything, beer or liquor is high in calories
