Your coffee is from where? California?

GOLETA, Calif. — There is a new crop growing in Southern California’s famous avocado groves — coffee.

About two dozen farms between San Diego and here, just outside of Santa Barbara, are nurturing coffee bushes under the canopies of old avocado trees, in what may be the first serious effort in the United States to commercialize coffee grown outside Hawaii, home of Kona coffees.

“When people hear I’m growing coffee, they typically make a face and say something like, ‘Well, how good can coffee grown in California be?’” said Jay Ruskey, the owner of Good Land Organics, who is widely regarded as the father of the state’s nascent coffee business.

The farmers are hoping to capitalize on a variety of changing factors abroad and here, including the aging of California’s avocado trees, which are producing less fruit.

The avocado growers face major disruptions in their business, including increased competition from Mexican imports, less access to water and rising real estate prices, all of which are forcing them to rethink that crop. But thanks to Ruskey, they have realized that their sprawling avocado trees provide perfect shade for high-quality coffee bushes.

One variety of Ruskey’s beans, Pacamara, emits an earthy scent like the smell of California dirt and new plants in spring. His Geisha beans have a light and fruity flavor with low acidity. Bourbon finishes with a chocolate taste.

As growers like him consider the move into growing coffee beans, they are eyeing machinery that can harvest the beans, which would reduce labor costs, as well as a contraption called a demucilager that mechanically strips coffee berry skin and pulp off the beans, rather than using water to clean them.

And they see more and more U.S. consumers willing to spend $8 or $12 for a cup of joe, which would offset their high costs of production.

At the same time, climate change threatens to damage the coffee crop in the tropical highlands that produce nearly all the world’s beans, potentially opening up a lucrative opportunity in the $20 billion export market for beans. Last year, some small Brazilian coffee farmers lost 90 percent of their crop to drought and heat, and similar conditions in Sumatra in western Indonesia made it uneconomical for many farmers there to harvest what little crop they had.

Ruskey has grown coffee on his farm for more than a decade, but it is only over the past three or four years, as his coffee started winning high scores in taste tests, that other farmers have begun to try their hands at growing it. Still, Doug Welsh, roastmaster at Peet’s, notes that the number of coffee bushes growing in California today is 30 times what it was 13 years ago when Ruskey started, or about 14,000 plants.

“We probably roast more coffee at Peet’s in one day than is being produced on all the farms growing coffee here, but I’m looking at this as a cup half full,” Welsh said. “It’s early days, but I think it could at least get to be as big as the Hawaiian coffee business.”

(There are roughly 800 coffee farms in the Hawaiian Islands producing as much as 9 million pounds of unroasted beans a year; California produces only hundreds of pounds. Globally 12 billion pounds of coffee are consumed each year.)

These growers aim to appeal to the premium coffee market. More than half the adult coffee drinkers in America reported drinking a specialty coffee daily, according to the National Coffee Association, or roughly twice as many as in 2010.

“People are shifting away from the way my grandparents drank coffee, which was at breakfast and made from whatever coffee was on sale — it was simply fuel,” said Peter Giuliano, chief research officer at the Specialty Coffee Association. “They’re willing to pay for something unusual.”

A pound of dried green specialty coffee beans can sell for as much as $120 in today’s market, according to Andy Mullins, a retired technology executive who has planted coffee on his property east of Santa Barbara. “You should be able to produce a pound for under $30, which is a superb profit margin,” Mullins said. “The only places that see better margins than that are software companies.”

Mullins is not a coffee drinker, but he caught the bug after visiting Ruskey’s farm, which cascades down a mountainside some 650 feet above the Pacific Ocean. Dragon fruit trees and finger lime bushes are interspersed among cherimoya and avocado trees, and each fruit crop is enlisted to help others grow. The avocado trees are the workhorses, acting as trellises for passion fruit vines and providing shade for the coffee bushes.

His profits from growing those unusual crops has helped persuade other farmers to take on the risk and expense of growing coffee. It can take as many as four years for coffee plants to get established, said Mark Gaskell, a farm adviser at the University of California, Davis, meaning a grower must make a significant upfront investment before seeing any return.

In addition, coffee is labor-intensive. Many of the coffee growers here are looking to Brazil, where coffee harvesting machines have replaced the people who picked and processed coffee, for ideas about how to reduce labor costs.

“The way they do it there would remind you of how cotton or almonds are harvested, highly mechanized and technical,” Welsh said, although he noted that such machinery tends to operate on large, flat spaces that are very different from coastal California’s mountainous terrain.

Willem Boot, a consultant to the coffee industry, said that in many ways, the climate along California’s southern coast was ideal for coffee. “You have colder nights and warmer days pretty consistently, and the temperature rarely gets close to freezing,” Boot said.

Such weather patterns allow coffee berries to mature slowly, which is the key to producing high-quality coffee. “Some of Jay’s coffees are truly excellent and can succeed in the specialty market,” he said. The farm’s Typica, a centuries-old Arabica variety, “is really great.”

In 2015, Ruskey took some of his exotic fruits and coffee berries to Re:co, the coffee industry equivalent of TED conferences. “It put coffee in the context of fruit,” Giuliano said. “Very few people in the world get to taste a coffee berry,” he said, but when they do, it’s easy to understand what makes the seeds inside, which become coffee beans, special.

A year earlier, Coffee Review, a trade publication, had given Good Land’s Caturra coffee a score of 91 out of 100, and depending on the roast, brew and time of harvest, the farm’s coffees have scored from the mid-80s to the low 90s on other quality tests.

“There’s no question that Jay has proved good coffee can be grown in California,” Giuliano said.
