Thanks a lot for pointing out that the summer beer festival is on! I just checked with two 7-11 in my street, and indeed the festival is on. Unfortunately one didn't have any of the special beers refrigerated, the other only one of them: A blue marbled can of "Kirin honkaku karakuchi mugi". I am drinking it as I write, and its not bad... but not my favorite at all: Not too weak taste, not too bitter, pretty refreshing - but: Dry, dry, dry.
In the non-refrigerated area there seem to be more: one "Bear Beer Strong Lager Denmark" went straight to the fridge, I will report back later. Funnily the little booklet which introduces the beers shows a German flag next to this undoubtly Danish beer. I guess it's as German as the Blue Girl :no-no:
Speaking of German beers... they also feature two definitely German products: Oettinger Hefeweizen and Öttinger Radler. First of all, I am afraid that Oettinger is, while well known and probably the best selling brand, rated VERY lowly in Germany. It is amongst the cheapest brews you can get, also owing to the fact that they do not advertise at all. It is often considered to be synonymous with "Pennerglück" (Hobo's delight) or Schädelbräu (Headache Brew). The two brews 7-11 carries are a Hefeweizen or wheat beer, which is pretty different from most other beers you get around here. Look it up on wikipedia. I did not try it, and surely will not pay, but a Hefeweizen in my opinion is an easy beer to make well, and also an easy beer even for non-beer-drinkers to like. So you might want to try this, but don't expect the epitome if German Braukunst The other one is a Radler (also known as Alsterwasser by the noth German Preissn), meaning a mix of beer and lemonade. This is a true favourite in summer days all over Germany, especially if you still have to drive (50% beer means you can dring 2x as much as of pure beer hehe). Should be VERY refreshing, but again I will not pay premiums for known sub-standard beers in Taiwan, so I leave the tasting to you guys.
