## About

Beer. It’s What We Do.
You tend to do what you love in life. Or at least that’s been a motto that Brian Oliver, Poseidon’s co-proprietor and head brewer, has made a point to live by. As far back as 2007, when he was stationed in Iraq, he discovered craft beer—and that he loved it. So in his downtime, he researched homebrewing…and got the craving to pursue it himself.

From Launch to Legit
No surprise, making a batch didn’t seem too difficult for this Navy-trained underwater construction diver. Right after returning to Ventura County, California, Brian took up the hobby with his wife, Vinita, who also appreciated high-quality beers.

Together, the couple sampled their brews with friends and neighbors, noticing the compliments, good times, and strong sense of community their hobby fostered. It inspired them so much that Brian, now nearing the end of his 23-year Navy career and feeling confident in his craft, took a leap and launched Poseidon Brewing Co., with Vinita’s support.

Bona fide Beer—and a Buildin’
Brewery immersion courses. Tons of planning and paperwork. Navigating challenges. Building a brand. Renovating the perfect location. The tasks seemed endless.

But in just six months, they made it happen, opening the brewery doors to a long line of thirsty beer lovers in summer 2014. Shortly after, the 500-square-foot brewery started pouring at local events and appeared on tap at restaurants and bars across Ventura County.
