It's the same thing with other foodstuffs too. For example if someone eats a very different diet from yours, eating a lot of foodstuffs you don't eat at all, you can smell it on them. Some people from foreign cultures might smell "spicy", and I've heard that Asians (actually living in Asia and not eating western food, not just by race) often think that westerners smell of milk due to the high content of milk, cream, ice cream, cheese, yogurt etc dairy products in their diet whereas dairy is almost nonexistent in trad. Asian cuisine.
Essentially, people smell change, people smell of what's in their bodies, and people who don't have the same stuff that you do in their bodies will smell it on you. So, sober people will smell high booze content in your blood off you no matter how much you gargle with mouthwash.
