Spiller, a former high school chemistry teacher from England, became fascinated with the idea of making whole-grain bread and growing organic wheat in the 1980s. The Ardenwood Historic Farm in Fremont offered the use of its space to grow wheat if she could find some varieties of wheat grown around 1900.
Her pre-Internet search eventually led to the U.S. Department of Agriculture, to Spiller's surprise. The USDA had been keeping seed stocks of wheat that modern farmers had mostly forgotten, occasionally replanting them to keep the stock fresh — for decades.
Spiller took various wheat seeds and planted them, for 10 years. "My lesson resulted in recognizing these old-fashioned varieties are the ones appropriate for organic farmers," she said. So she became a self-appointed marketing person for these grains, connecting farmers who could sell each other seeds, or buying and selling them herself.
She believes the most popular type, Sonora wheat, was grown by Native Americans in the Southwest for years before the Juan Bautista de Anza expedition in 1775, and that it was grown in California until modern, engineered wheat varieties took over in the 1950s. Sonora wheat can be grown without pesticides, fertilizers and irrigation, and it grows tall above the weeds that organic farmers often battle, she said. When turned into flour, it makes a stretchy dough that lends itself well to making tortillas, pasta, pastries, flatbreads and pancakes.
Spiller's nonprofit, Whole Grain Connection, now sells Sonora and other heirloom wheat seeds for $1.25 a pound. While she's not looking to make a living on it, she's sold her seeds to 90 organic farms, many of which had been using modern wheat seeds in their crop rotations to build the soil. Unlike "terminator seeds" that are genetically modified to be sterile, her seeds need to be bought only once, she said.
Spiller said she hopes to work herself out of her seed-marketing business eventually. She's moved into the flour and pasta business and soon will offer bread made from the wheat she's marketed.
Spiller's Whole Grain Connection label can be found on pasta and whole-grain flour sold at Country Sun Natural Foods in Palo Alto. The pasta and flour are available in two varieties: Sonora and Ethiopian Blue Tinge. Whole Grain Connection's flour is ground by Giusto's Specialty Foods in South San Francisco, while the pasta is made by Pasta Sonoma in Rohnert Park. The wheat for both comes from farmer Fritz Durst in Capay, Calif.
Spiller has also lined up a bakery to produce bread for the Whole Grain Connection brand. She is currently looking for someone to help her market the pasta and flour to other grocers.
The use of locally grown wheat is a growing trend, especially for pasta-making. Despite its rougher texture and darker color, an increasing number of restaurants and grocers espousing sustainable local products are reportedly looking for pasta made from locally grown wheat.
"The trend that I'm trying to ride is the local food movement," Spiller said. "It gives us the opportunity to produce whole-grain products rather than refined grain products."
The difference between refined and whole grains is an important one to Spiller. Her late husband, Gene Spiller, authored books on the dietary benefits of whole wheat that are still widely read. She coauthored one of his books, "What's with Fiber?" in 2005, the year before he died.
"It was through that work that he did that I understood that the biggest need we have in our diet is whole-grain foods," Spiller said. She described her husband as "at the forefront of the dietary-fiber movement."
Like his wife, Gene Spiller was an advocate for returning to old-fashioned ways of eating. His book "The Power of Ancient Foods" says, "In order to choose a more healthful way to eat we expect formal statements by major research or government organizations — all this while the peasant of Crete and the Incas of Peru knew ages ago all we need to know about healthful foods."
Spiller said she believes that many modern diseases can be traced to the increased use of refined grains, including digestive problems, obesity and diabetes. Whole wheat is ground in such a way that it leaves intact the vitamins and minerals necessary for the human body to properly digest the protein and starch in the grain, she noted.
Because of conventional agriculture's dependence on artificial fertilizers and herbicides, "the ground is depleted, really," Spiller said. "I'm trying to encourage these organic farmers to use wheat in rotation with legumes to rebuild the soil and produce a good soil. It will take a number of years."
She added, "The same field of Sonora doesn't yield as much as a conventional field." But because it does not require herbicides, irrigation and fertilizers, she said, "eventually I think this old-fashioned, organically grown wheat will be less expensive than conventional wheat."
