Mutantis Brewery & Bottle Shop was founded in 2019 by Jason “Igliashon Jones” Yerger, often known as “Igs” by those who appreciate brevity.

Born and raised in the San Francisco Bay Area, Igs developed a passion for craft beer while earning his philosophy degree at UC Santa Cruz.  He initially took up homebrewing after learning about ancient unhopped herbal beers known as “gruits”, but after learning the hard way about the unpleasantly bitter and vegetal flavors of a lot of those old brewing herbs, he decided to shelve the brewing equipment and focus on other hobbies.

Diagnosed with celiac disease in 2008, shortly after his 25th birthday, Jason soon came back to homebrewing, in a quest for better gluten-free beer than he could find at the time.  His gluten-free experiments faired much better than his earlier hop-free experiments, and before long his passion had become an obsession.  Documenting his experiments on his blog, as well as the gluten-free forum, he eventually caught the attention of a couple of fellows from Seattle, WA.  Through a strange turn of events, Igs suddenly found himself relocating to Seattle to partner with them in launching Ghostfish Brewing Company in 2013.

In 2018, after five years of making award-winning gluten-free beer at Ghostfish, Igs decided to leave the company to pursue smaller things.  He relocated to Portland, OR—the global epicenter of gluten-free craft brewing—and swiftly got to work on starting Mutantis, where his whimsical brewing experiments will be right at home!
