Smelling like a “brewery”

So today, Wednesday, my supervisor told me I smell like a brewery. I was perplexed because I didn’t have any beers since the previous Saturday. I had a 6 pack with my friends on Saturday to watch the Supercross race. I don’t drink the day before a work day ever. I’m confused as to what it could’ve been to make me smell that way. I have been eating a lot of saurkraut, garlic, and onions with my food the past few days to help my digestion out. Not sure if that does the same thing. Now all I can think about is him thinking I’m lying about not drinking the night before. Can the smell of beer really last that long on someone?
