will it hurt you to drink a lager 2 years out of date ? 10 points?!
It probably would. And most lagers are cheap enough - just get fresh beer.
It will probably make you sick, not only because of the taste, but the yeast cultures would stir up something nasty when they are that old.
It shouldn't hurt anything but possibly your taste buds.
I would, but go out and have a drink its Friday
