Labatt is a brand name, they make blue, blue light, 50, genuine lager, ice, extra dry, etc. I don't think you need to put "Labatt Blue". If you go into the beer store and say gimme some Blue, they'll know exactly what you mean.
2nd, Molson is also a brand name, if you walked into the beer store and said gimme Molson, they would ask which one. They brew Canadian, Canadian Light, Export, Dry, M and of course the now discontinued Golden.
Don't you know a quizz about beers must be "belgo-centré" ?
