Breakside Brewery is releasing a limited-edition brew called “Nature Calls” that’s infused with bear poop. Yep, bear poop. Why Bear Poop Was Used in This BeerAccording to Bro Bible, Breakside Brewery has teamed with Columbia Sportswear for this intriguing concoction. So, where is Breakside getting the bear poop? The poop “was “infused” into water from the Bull Run River before it was processed to make it safe to drink.” Nature Calls is described as having “notes of honey and huckleberry.” Of course, they chose Montana bear poop to use, after all everyone knows it's the best.
