I did this last weekend but my recollection is a bit fuzzy. I think that Germany won.
#1 Germany - Warsteiner is great beer.
#2 USA - The Rogue beer was something special and I'm going to try as many Rogue varieties as possible. I've already bought more Dead Guy Ale. The other beer was terrible but I made a mistake in buying gluten-free so I will take that out of the competition.
#3 Switzerland - Lowenbrau is actually brewed in Germany but it is a good beer.
#4 France - this one surprised me. I remembered Boris being a lot worse and I did not remember Kronenburg tasting this smooth or having this much character. For the price Kronenburg could become my regular beer.
#5 England - I really really like Hobgoblin and I buy it semi-regularly but the Innis&Gunn was terrible. Oak-aged beer is not a good idea and this was the most expensive beer, maybe it's an acquired taste so I'll give it the benefit of the doubt.
#6 Japan - Sapporo and Asahi are very smooth very light beers. I like them as summer beers.
Inoffensive: Brazil, Holland, Slovenia, Africa, Mexico. Brama, Heiniken, Lasko, Tusker and Negra Modelo are all blah. Nothing special about any of them. But not terrible.
Last place. The bad beers:
Italy - Moretti is just terrible. It tastes like it is just about to go skunky. I've had it many time and it is the standard taste of Moretti.
Denmark - even though Tuborg is ok Denmark is in last place because of Faxe. This is a dark beer that should never have been made. It was 7.7% so I expected it to taste a little strong but it was overpowering and ghastly.
