A former Budweiser executive was “way, way wrong” when he likened the cannabis industry to craft beer, the founder of Lagunitas Brewing Co. told marijuana industry leaders.

“I think (cannabis) is going to be way, way, way, way bigger,” Tony Magee said Wednesday in the opening keynote address at the National Cannabis Industry Association’s two-day Seed to Sale Show in Denver.

Magee — whose California brewery was shut down at one point for 20 days because of marijuana use on-site and who later would sell that brewery to beer conglomerate Heineken N.V. — spoke about the correlation between the craft beer and cannabis industries. He also touched on what role traditional industries and companies like Heineken might play in marijuana’s future.

Describing his tenure in craft beer as “24 years of life on the nose of a rocket ship,” Magee implored cannabis entrepreneurs to prepare for any economic convulsions or industry consolidation that may come.

“You’ve got to be thinking about this stuff today, while you’re in the boom time, that you plant the right sorts of seeds and grow the right kind of company that you can persevere into a future that will have constraints that are not present today,” he said.

Cannabis can learn from American craft beer’s booms and busts, Magee said, outlining how breweries grew organically, then through acquisitions experienced a bottleneck with the rise of regional distributors. Since the mid-1800s, the number of breweries fell from the thousands to the dozens in the late 1970s and climbed back up into the thousands in the 1990s, he said.

When access to opportunity contracts, “you need a big brother,” he said.

For Lagunitas, big brother turned out to be Heineken, which acquired a 50 percent stake in the brewery in 2015. The Amsterdam-based brewing conglomerate would acquire the other half nearly two years later. Terms of the deal were not released, but analysts’ estimates at the time put the deal at $1 billion.

“It’s not the same as selling out … it was the necessary step not for today, but to prepare ourselves for the world coming 10 years from now,” Magee said.

Cannabis, like Lagunitas, should emphasize branding that shows people “what you live and die by.”

Lagunitas, for instance, frequently allowed customers and Sonoma County neighbors into the brewery for cannabis-friendly gatherings. It also developed uniquely branded brews telling the company’s stories, including the aforementioned 2005 raid, which is now commemorated in Undercover Investigation Shut-Down Ale. Last August, Lagunitas debuted SuperCritical, an IPA made with marijuana terpenes provided by CannaCraft, a California company that makes cannabis vape cartridges.

“What’s important is to do things that amaze your customers, I think, even if it does sort of rub up against the rules,” he said. “Because people chafe against the rules, just like you should.”

Retail sales of craft beer — defined as small, independent and traditional — totaled $23.5 billion in 2016, according to the most recent full-year statistics from the Brewers Association, the Boulder-based trade association for craft brewers. Craft beer sales accounted for 22 percent of the $107.6 billion U.S. beer market, Brewers Association data show.

The U.S. cannabis industry generated $6.6 billion in sales in 2016, according to New Frontier Data, a Washington, D.C.-based cannabis analytics and research firm.

Even while cannabis companies should prepare for unique business opportunities involving large, traditional corporations, they also need to brace for competition with them, he said.

“Those guys are going to open the doors for you,” he said, noting Consumer Packaged Goods businesses could push federal legislation paving the way for cannabis-related operations.

“They’re your best friend from a legalization standpoint,” he continued. “You need to be their biggest enemy once they come into the market. But you only do that by being way, way, way ahead of them, and they’re pretty smart people.”

Those traditional, large-scale entities are closely examining the cannabis space, looking for windows of opportunity, he said.

That includes Heineken, which recently rang him to learn about the cannabis space, Magee said.

Last fall, Constellation Brands, a Victor, N.Y.-based seller of alcohol brands such as Corona and Ballast Point, invested upward of $190 million in Canada marijuana company Canopy Growth Corp. with an eye on eventually developing cannabis-based beverages.

While some research reports have positioned legal cannabis in opposition of the alcohol industry, the sales declines experienced by large U.S. brewers don’t necessarily translate to the craft beer sector, Magee said.

As such, the cannabis and craft beer sectors already are “inextricably connected” and there’s potential for future collaboration, he said.

Cannabis cultivators are tapping into the experience of hop growers in the Yakima region of Washington State, he said, and craft brewers are starting to implement extraction technologies honed by marijuana manufacturers,

“Why shouldn’t Led Zeppelin learn from Picasso?,” Magee said. “This is what art is about, creativity is all about. And at this point in time, craft brewing is still much about art and certainly cannabis production is about the art and the creativity to determine what comes next.

“Because the future is coming toward both industries so quickly.”
