Well, beer in general doesn’t travel well, so I’m going to guess “no”.
I ran across an article about a study by the Institute of Food Technologists (link in the sidebar) which sought to find out if there was any truth to the idea that Guinness served in Ireland tastes better than that which is served elsewhere. Their preliminary results indicate that, yes, Guinness served in Ireland tends to score higher in flavor preference to those outside the country, even after accounting for various variables.
I’m not surprised. In fact, I bet this is the case for most any beer in the world: it’s very likely going to taste better the closer you are to the brewery. This is because there is less transportation and time required to get the beer to various parts of Ireland compared to the rest of the world, meaning less time for the flavor to deteriorate from oxidation and aging. Also, Guinness probably has more influence over local bars and how they maintain their tap lines. This is also related to proximity; there are probably more Guinness reps combing the pubs of Dublin than there are in Boston. They also mention the affect on popularity and the effect on freshness: Irish pubs will probably be going through more Guinness than pubs elsewhere, meaning there is fresher beer on tap since the turnover rate is higher. All of these factors should be no-brainers.
Other thoughts I had when I read this was about the methodology. I haven’t read the paper, but I’m going to assume that all 4 researchers tasted Guinness in a number of different countries, and overlapped their territory, because otherwise there would be no way to control for the “assessor” variable during the analysis. I also note that in the abstract, they say their researchers were “non-expert”. I would have hoped that they would have had some level of beer flavor training, however basic, before undertaking this project. Another thing I wondered about is how they controlled for the “ambiance” variable. While they did mention the possibility that ambiance could affect the assessment of the beers, in the abstract they say the statistical significance remained even after controlling for ambiance. Now, I’m not sure how you can control for ambiance without tasting all the beers in a single location; it doesn’t make sense to me.
I was also a bit irked at the tone from the following passage, which seems to assume that the Journal of Food Science, or beer research in general, might be considered a non-scientific discipline:
That the Journal of Food Science is a serious publication can be inferred from some of the other material in the March issue. One feature is headed: “Technological Optimization of Manufacture of Probiotic Whey Cheese Matrices”. A second reports: “Improved Sauerkraut Production with Probiotic Strain Lactobacillus plantarum L4 and Leuconostoc mesenteroides LMG 7954”.
It’s almost like they needed to convince themselves that Food Science is actually science…
PS: the pint of Guinness I had at the Panorama Sky Bar at the end of the Guinness tour was the most expensive “free” beer I’ve ever had: 17€. But they poured a little shamrock in the head of the beer, so that’s got to be worth something, right? Of course the 17€ was for the tour of the “brewery” (read: “museum”), but really the only worthwhile part of the tour was the view at the top and the pint in your hand.
