How Firestone Walker went from a vineyard shed to a global craft beer brand

Firestone Walker, the San Luis Obispo County brewery that started in the shed of a Santa Ynez vineyard, has grown from modest roots into a juggernaut that, after three decades, has firmly established its name in the craft beer world.

This year, it’s celebrating its 30th anniversary, kicked off by a period of new expansion, as it continues to acquire labels, add new beers and widen its already impressive national reach and international reputation.

The family-owned Firestone Walker partnership has brewed its way into award-winning history with such beers as its 1996 DBA (Double Barrel Ale, partially fermented in oak barrels and still unchanged, going strong) and its flagship brew, 805, a pale blond ale that remains the company’s No. 1 seller, even 14 years after its introduction in 2012.

The brewing titan spent the last 30 years developing new beer flavors and styles with constant trial and error

Those have taken Firestone Walker to reputational heights beyond what was dreamed of by its founders, Adam Firestone and David Walker.

So just how did they do it?

Walker, now 62, and Firestone, 64, are friends and brothers-in-law, linked initially through Polly Firestone, who is David Walker’s wife and Adam Firestone’s sister.

Then, the guys’ shared love of beer, a yen for a decent locally brewed ale and a burning desire to find or develop their own perfect brew turned their passion into an itch to do it themselves.

Adam Firestone has since passed his family’s portion of the partnership to his son Nick Firestone, who’s now the Firestone Walker CEO.

But according to his 64-year-old dad and Walker, the patriarch remains active in the brewery, with equal measures of participation and pride in what they’ve all accomplished.

The men talk “at least daily,” Adam Firestone told The Tribune. “Nick is clearly at the helm, but David regularly interrupts him.”

The brewery, which is the latest chapter in the century-plus Firestone family dynasty, has grown into a major operation in Paso Robles, expanding in the location that was the former brewhouse for SLO Brewing Company.

And it only continues to push further forward, with 2026 turning out to be a very busy year for Firestone Walker, especially in April.

That month, Nick Firestone and Walker bought Stone Brewing Company in San Diego, a subsidiary of Sapporo USA, plus four Stone Brewing hospitality locations in Southern California.

Right before that, Firestone Walker inked a deal to buy the U.S. rights to brew, market and sell a popular Austrian pilsner that’s been made in Berkeley since 2004.

Trumer Pils is a division of 400-year-old Trumer Privatbrauerei in Salzburg, Austria, an international craft brewing company that has been owned and operated by the Sigl family for eight generations.

It’s clear Firestone Walker continues to not only innovate and grow, but also have fun doing it.

Just last month, the company’s sold-out, three-day 2026 Invitational Brew Fest and Block Party on May 29-31 drew a crowd of 4,000 enthusiasts to the Paso Robles Event Center, according to a spokesman.

And a new brew, SLO CAL pale ale, an ode to SLO County, was launched at the event by longtime brewmaster Matt Brynildson, 55, (nickname “The Wizard,” which is why a wiz is a symbol for the Brew Fest).

Firestone Walker is still ‘a familial, proprietary brewery’

Firestone Walker Brewing Company’s reputation draws on a century of a patriarchal dynasty that started in 1900 with Harvey Firestone’s namesake tire company.

The industrial and commercial legacy continued and grew at Firestone Winery and Vineyards in Santa Barbara County with son Leonard and grandsons Brooks Firestone (a former California winemaker and politician) and Adam Firestone. The latter then expanded the family’s reputation as co-founder of Firestone Walker.

Then, in 2015, Belgium’s Duvel Moortgat USA, another family-owned brewery, acquired a majority ownership of Firestone Walker. That created a partnership that, according to the Firestones and Walker, has allowed the Central Coast brewery to expand without taking on generational debt.

“Firestone Walker went from being owned by two families to being owned by three families,” Nick Firestone said.

He defined Duvel as being “great partners, sort of involved when we need them, but they keep out of the day to day. They come in to remind us, they’ve been in business for a very long time, through two world wars, which gives us a real perspective on our woes.”

Walker said the Duvel deal came along at just the right time.

“Duvel was another piece of serendipity,” Walker said. “We needed a financial partner to help us keep up with 805’s growth, and we were fussy about who that partner might be.”

The Belgian brewer “is around four times bigger than us, so they brought some simpatico, stability, understanding of our challenges and real resources to help us grow,” he said. “More importantly they needed us to remain engaged as we were and healthy.

“We retained enough of the brewery for us to continue building and operating our vision for a generational craft brewer,” Walker said. “It’s still our child. … Call it a modern family.”

Firestone Walker’s backstory is all about relationships

Firestone Walker was born in 1976, in a ramshackle shed on the “back forty” of Firestone Winery in Santa Ynez, using “borrowed equipment and a lot of belief,” Walker said.

“Adam and I often see the world differently,” he said of his former partner in a 30th anniversary essay on the brewery’s website. “He builds patiently and protects what matters. I can be restless, wandering just far enough ahead to see what else might be possible. That difference was never a liability. It became our strength.”

By 1981, production demanded larger quarters, so they moved the operation to a warehouse in Buellton, which has remained a taproom and the so-called “Barrelworks,” out of which the partnership runs their wild ale program.

Eventually, “Adam converted the original outbuilding back to a wine building, and it’s now contract space for another winemaker,” Brynildson told The Tribune.

Then, in a healthy dose of good fortune in 2001, the large Paso Robles location became available.

Firestone Walker’s brave expansion was “a life-changing event,” Adam Firestone told The Tribune.

“(It was) massively risky for us as we were so financially burdened,” he said. “But we made the decision to decamp from our first modest brewery (located in an old warehouse) and channel all our energies into 1400 Ramada.”

“Fortune favored the bold — it turned out to be the best decision we ever made,” Firestone said of the move.

From there, it’s been onward and upward for the craft brewery, with three locations and many different beer brands of various types, such as IPAs and pale ales, blondes and wheat ales, lagers and pilsners, stouts and barrel-aged varieties.

As of May, the brewery touted 32 different labels on its website. Some are variations of the same brand, such as Mind Haze. Some are vintage flavors. Even the brewery’s most famous ale, 805, has a couple of variations, including the nonalcoholic 805 Zero.

And as always, there’s more to come.

Who are the Firestones, Walker and Brynildson?

The brewery is the much-loved life’s work for Walker, Nick Firestone and Brynildson.

“Adam came from the wine industry ... he knew sales,” Brynildson said. “David came more from the tech side and is great at the front of the house.”

When he switched employment from SLO Brewing to Firestone Walker in 2001, Brynildson said, “I was the guy who knew how to run a brewery. It was a wonderful partnership between the three of us.”

Brewing would have seemed a stretch for Walker, after his earlier careers in vineyards and developing businesses in the world of high tech.

“Neither of us had any belief that it would grow to what it has become,” he told The Tribune. “When we started the brewery, there were 300 brewers in America. Today there are nearly 8,000 … but this brewery has a great personality.”

That would seem to reflect “the fierce pride of the Central Coast,” Walker said, plus the passionate, articulate nature of the three men now at the helm, as well as cofounder Adam Firestone.

“We weren’t strangers to that world,” Walker said. “Adam was running a third-generation family winery, and I was living on a vineyard growing grapes on the Central Coast. … It wasn’t a huge leap. The fact we both loved beer and drank it as often as wine might have been the real driver. Make wine, make beer!”

For Nick Firestone, the alchemy is what makes the business special.

“There’s something magical about fermentation,” he said. “It’s alive, it’s a process, it has its own personality traits.”

His fermenting experience isn’t limited to wine and beer, he said. “I bake bread, have a starter in my kitchen. It’s amazing how the process is.”

In the initial partnership, “David was the dreamer, the big picture guy. He’s fun, gregarious and connects well with people,” Nick Firestone said.

His dad, he said, “was always more anchored and focused. He wasn’t patient. Dad is very structured in his thinking, a dynamic guy … at the dinner table, he still always has plenty of opinions.”

Between the two co-founders, their creation probably was a blend of experiment, whim, test run and a carefully planned-out business venture, Nick Firestone said.

“It was somewhat whimsical,” he said. “They were prospecting on an adventure. I think of myself as a hybrid between them.”

Despite his decade doing other things — his first jobs there in the so-called “dish pit” dishwashing/sanitizing sinks, warehouse and taproom — “I was always interested in coming back to the family business.”

“I always loved the energy of the place, and even more so, the people,” he said. “So, I bounced around between the U.S. Naval Academy and the Marine Corps, grad school and a handful of finance and strategy jobs for about 10 years before eventually finding my way back.”

As for Brynildson, “I naturally got interested in beer as a college student,” he said with a laugh. After getting a degree in organic chemistry, he attended the Siebel Institute of Brewing Technology, the oldest brewing school in the United States, and then went to a brewery job.

“When SLO Brewing offered me an opportunity to work in this beautiful place on the Central Coast,” Brynildson leapt at the chance, he said.

After SLO Brewing Co. closed its Paso Robles campus, “Adam and David bought it and brought Firestone Walker in. They asked me to stay as the brewmaster.”

Walker noted what a critical decision that turned out to be.

“Matt brought clarity where there had been instinct, and precision where there had been intuition,” Walker said. “He knew what the beer wanted to be, then helped it come of age.”

The present brewery triumvirate has been in place ever since, making beer history in San Luis Obispo County and beyond.

Where are the Firestone Walker locations, and what happens at each?

Today, the North County campus remains the mother ship for the brewery, according to the three men.

“Paso is where 99% of our beer is made,” Brynildson said.

“We brew a small volume of beer at our brewpubs in Buellton and Venice Beach,” Firestone said, which his brewmaster defined as “satellite locations with pilot projects.”

In March, for instance, the company “brewed and packaged about 150,000 case-equivalents of bottles,” Firestone said in April.

With their approximately 400 employees, Walker estimated Firestone Walker produces “a half-million barrels of beer a year. Each one is 31 gallons. A case of beer holds about 2.5 gallons.”

The Buellton location has remained a taproom with a Propagator brewhouse, now also with a gastropub restaurant. It’s also the brewery’s 7,000-square-foot wild-ale producing “Barrelworks.” The Venice Beach location also serves an experimental role.

“The Propagator is where ideas are allowed to wander before they are asked to behave,” Walker said.

“We make fermentation ‘sour beers’ there, too. They’re more tart than usual and often contain fruit,” Brynildson said. “It’s a whole different kind of brewing, very much based on a Belgian process, and it’s a trend in craft brewing. It uses wine barrels, and grapes when we need to.”

Beyond the brewing facilities and taprooms, Firestone Walker still has to convince the buyers who distribute and sell the beer.

“We have operations in 23 states, and 80% of our beer is sold in the state of California, which is a statistic we are very proud of,” Firestone said in April. “While some of our beers have made their ways overseas, and we have landed awards at beer festivals around the world (Firestone Walker was named 2025 Champion Brewery at the Japan World Beer Cup), we have no international expansion plans as of yet.”

In fact, “Firestone Walker has won awards in all the major competitions that we have entered the past year, including the World Beer Cup, the largest international beer competition in the world with more than 8,000 beers entered from 49 different countries,” Brynildson said.

As for how to have the best beer-drinking experience possible, Brynildson has some advice.

“Foam is an important part of any beer experience. A perfect pour should always include a proper head of foam.” he said. “Foam is the result of CO2 being released and that releases the aromas of the beer to your senses.”

When pouring a glass, he said, “Take your time. Don’t hesitate to, at first, pour the beer down the middle of the glass and create some foam. Let that settle (it can take minutes not seconds) and then complete filling the glass. In the end if you have a couple fingers’ width of foam at the top of the glass, you are ready to taste.

“I love the challenge of meeting someone who claims not to like beer. That usually means they simply have not been introduced to the right beer,” he said.

What’s ahead?

Today, the innovating continues at Firestone Walker, including adding another 5 acres to the solar array behind the building, Nick Firestone said of their emphasis on being sustainable.

“Brewers have been practicing sustainability since it was invented, with a core idea of let nothing go to waste,” he said.

All that said, “beer is fundamentally an art form, a commitment to quality, purity,” the CEO said. “We make beer that’s intentional, artisanal, grounded in beer-brewing tradition. Our motto is ‘Beer before glory.’”

“Thirty years is a long time to do anything the same way,” Walker said on the website. “It feels less like a finish line and more like a brief pause, a chance to look around, take a breath and notice how far the path continues.”

Firestone and Walker never forget that “if the beer sucks, your name is on it.”

“The real story isn’t the beer. It’s not my family,” the Firestone heir said.

“When you walk into our brewery, you’re greeted by smiling people, amazing people who live on the Central Coast,” he said. “We keep the brewery going so those passionate people can continue doing what they love and are good at … making beer. It’s a reflection of the diverse collection of people and SLO County.”

Add dedicated customers all across the country, the fourth-generation brewing Firestone said, “and we feel that, somehow, we hit the lottery to be in the middle of that mixture.”
