I'll tell you, the variation in ease of label removal is remarkable. Around here, I've found the easiest labels are Amber Bock (though the bottles have a raised 'Michelob' on the glass, which isn't removable and makes them ineligible for competition), and the gosh-darndest are Saranac, with not a single clean removal out of a sampler pack.
When we were getting ready to bottle our first batch, I invited a bunch of folks over who had expressed interest in consuming the final product, telling them the ticket price for homebrew was a six-pack of pop-top bottles. No one understood my surprise at their Coronas.
That'll teach me, have to be more specific next time.
