Would you believe this island has a microbrewery? Well, it does indeed. The Rise Bryggeri makes 3 types of brew: Ærø Pilsener, Ærø IPA, and Ærø Dark Ale. I tried the first two -- they were both quite good. The beer is available in bottles at the Ærøskøbing Bakery, as well as many restaurants around town, including Restaurant Ærøhus.
As you walk, bike or drive around Ærø, you'll see several stands selling various farm products. Prices are posted next to the items. The way it works: you take what you want, you leave what it costs. I'd expect this would work for about 15 seconds in most of the world, but it seems to work just fine here.
In the picture you can see the doubled mirror on the window. You know why is it there? The people sitting at their homes can look at the mirror and observe the whole street even without opening the window or going out. So be careful, even if you can't see anybody around you, maybe somebody is watching you! :)))
Now perhaps this is an opportunity to inroduce you with some village culture. You may find some handicrafts in front of some doors where the prices are written and if you feel like you may buy giving the exact change in the pot. Its common in villages that people often put something on sale with the appropriate price with no attandance.
If you happen to tour the island of Aero by bike, you will probably need to stop at one of the typical woodden stalls where the farmers sell their fresh products. You put the money in the safe box and you just take what you want. Actually, this method is one of the most civil I have ever encountered... Just think of it in Italy!! The whole stall would disappear in a few seconds...
