We’ve seen some pretty strange beer flavors—from spicy Sriracha to peanut butter and jelly ale, even a cornucopia of candy flavored brews.

But a new concoction from Icelandic brewery Steðji seems to defy all sense of taste logic with an unconventional ingredient—whale testicles.

For its winter ale “Hvalur,” the brewery teamed up with a local whaling company of the same name. According to the product website, the beer is made with “Pure Icelandic water, malted barley, hops and sheep shit smoked whale balls.” We’re not sure if something is lost in the Nordic translation but according to Steðji, this is a traditional method of smoking that has been used in Iceland since the Vikings were in charge.

The beer ends up with an “excellent smoke taste, a smoke taste you haven’t tryed [sic] before…”

Animal rights activists, including Vanessa Williams Grey of the Whale and Dolphin Conservation (WDC), are critical of the brew.

“Reducing a beautiful, sentient whale to an ingredient on the side of a beer bottle is about as immoral and outrageous as it is possible to get,” Williams Grey told the Guardian.
