Dogfish Head (the brewery) is right here in little 'ol Delaware. Even if it weren't my hometown microbrewery of choice and there was no bias, I think I'd still be a fan after trying their line of IPAs.
Dogfish Head is well known for their crazy beers. One of my favourites is the Midas Touch, not mentioned in the article, but one of the first attempts at recreating ancient beers.
Is this even technically a beer? I know that there are beers made with rice (like Budweiser), but they are still barley-based. In Germany, this would definitely not be considered a beer...

Germany may be a more diverse place than you're aware. The Reignheitsgebot originated in Bavaria and was a condition of the German unification in 1871. However, many areas of Germany have long traditions of non-Reignheitsgebot beers, for example, wheat beers and spiced beers in northern Germany.
