I never actually stopped to think about there being a difference. I know the cans get colder, at least they seem too, but didn't know there was a difference in taste. I always gravitated to the bottles just because I liked the look of them lol.Don't waste your time on the bottles. get the cans... The widget seems to work better, and just seems to be a "draft like" taste... the bottle still taste great!!! but seem to fall flat, maybe not enough nitrogen? I dunno...
