There is the potential that beer labels will have to squeeze in a lot more information onto them in the future. More specifically, allergens and nutrition information. Which is not good for those, like me, who need major magnification just to read what hops are in the beer. And though I like the idea of a QR code that leads you to more detailed information, what percentage of people are going to use that and then what percentage of those will understand the governmental gobbledygook that passes for information?
