Those pretentious beer snobs may be right: Ever get told that, to really appreciate a Guinness, you have to travel to Ireland? Four researchers took it upon themselves to travel the globe and find out, collecting "data on the enjoyment of Guinness and related factors." The enjoyment of the stout was tested in 71 pubs spread over 14 countries, and the conclusion is that it really is more enjoyable on its home turf, a finding that "remained statistically significant after adjusting for researcher, pub ambience, Guinness appearance, and the sensory measures mouthfeel, flavor, and aftertaste." However, the researchers admit that their study has some limitations, so they're hoping to expand on it a bit.
