In this week’s do-not-miss world of beer news, it appears the Icelandic brewery Borg Brugghús has created a beer that gets its unique taste characteristics from, yes indeed, sheep dung.

The malted barley that goes into their Fenrir Nr. 26 is smoked over burning Icelandic sheep excrement for several hours, resulting in a brew that is, according to brewmaster Sturlaugur Jon Björnsson, “Þetta er í raun léttur IPA bjór með sítruslegt og ferskt bragð og lykt frá humlunum. Síðan kemur svolítið þyngri, taðreyktur fílingur í þetta en þetta gengur allt saman upp.”

For the non-Icelandic among us, that more or less translates as “It’s a lightweight IPA with fresh citrus and hop notes, then comes a bit heavier taste from the…” Well. You get the idea.

This sort of madness isn’t exactly new—witness Beer Geek Brunch Weasel beer from Denmark craft beer superstar Mikeller, which derived some of its flavor from Vietnamese ca phe chon coffee (beans harvested from civet cat poop). But, you know, it’s still not exactly mainstream.
