MEET OUR MAKERS: Geoff Seideman, Honolulu Beerworks

“Especially on Oahu, being the only independent brewery, we have that luxury of saying, ‘Okay let’s experiment, let’s have fun.’"

Four years ago, Geoff Seideman’s wife, Charmayne, gave him a home brew kit for Christmas.

It was the start of an obsession.

Today, Geoff and Charmayne are the owners of Honolulu Beerworks, Oahu's premier, independent brewpub. Our Kaka‘ako is a long way from Philadelphia, where Geoff grew up. He took a Hawai‘i vacation 15 years ago with Charmayne and they left the frigid weather of the Jersey Shore behind ever since.

With a taste for home brewing, Geoff started volunteering at local breweries. He became the assistant brewer of Aloha Beer's Dave Campbell for 2 1/2 years.

When the opportunity to open his own brewpub in Our Kaka‘ako came along, he used all of his skills—his Kapiolani Community College culinary degree, his construction background, even his experience as a certified mechanic—to build Beerworks from the ground up.

“I was kind of selfish, in a way. I built a place I wanted to go drink at and hang out at. I was hoping everybody else would feel the same way.”

Using retrofitted garages and warehouses in Portland and San Diego as inspiration, he transformed a boarded up, Kaka‘ako warehouse into Honolulu Beerworks, mostly by himself. He built interior walls, a grain room, a walk in cooler and a massive bar. It took about nine months from demo to completion.

Today, Honolulu Beerworks is open and is perfecting the art of brewing special release beers. For instance, when Kamehameha Schools asked Honolulu Beerworks to create a special beer for their Mahi‘ai gala, supporting local farmers, they created a Mahi‘ai Cezanne. It used local oranges, lemons, limes, tangerines, lemongrass and Big Island honey. The Mahi‘ai Cezanne is now one of their number one sellers.

“Out of that little collaboration came one of our flagship beers which highlights local ingredients.”

And collaboration is one of the things Geoff loves about being one of the founding makers of Our Kaka‘ako.

“Everybody’s supporting everybody else, which is great. We feel lucky that we’re in this type of neighborhood and community. We’re kind of on the ground floor. Not a lot has been built out yet, but it will be.”

What started in an abandoned warehouse is now growing. Honolulu Beerworks is in the midst of an expansion to increase capacity for future distribution to craft pubs, restaurants and hotels. Geoff’s come a long way since unwrapping that home brew kit not so long ago.

“In five years we want to be canning, we want to have a world class barrel aging program. We want to be Oahu’s craft brewery.”
