People are loyal to brands for numerous reasons, one of which is the sense of continuity they offer. For instance, if you have a bottle of Corona in Mexico, it’s pretty much guaranteed to taste the same as the one you consumed in Montreal or Dublin. Draft beer should follow the same rule: regardless of where you consume it, the beer on tap here will taste like the beer on tap there.*
One would assume the same goes for how intoxicated you’ll become from drinking draft: a pint is a pint, and the effect is the same regardless of where it is consumed. Right?
