Emil Clemens Horst was a major figure in the cultivation, harvest and sale of hops in the United States. Horst emigrated to the U.S. as a child in 1874 from Tuttlingen, Baden-Württemberg, Germany. In the mid 1880s he purchased a small plot of land along the Bear River, near Wheatland, California, and began cultivating hops. He soon bought out two other hop growers, Hugh Roddan and Joseph M.C. Jasper. By 1898, Horst's operation had grown to the point that ten hop drying kilns ran daily during the harvest and a company town, large enough to have its own post office, was started on the ranch to support the thousands of migrant workers who picked the mature hops each year. Given the significance of Horst's ranch, certain loamy floodplain soils found in the area were later named after him. Horst married in 1898, and moved to San Francisco in 1902. By 1904 he was supplying Oregon hops to the Guinness Brewery in Ireland. By 1912, Horst owned the largest number of acres of hops under cultivation in the world with offices in Chicago, New York and London. Horst Company was headquartered at 150 Pine Street, San Francisco, California. Prior to World War II, Horst Company was the only exporter of hops to Germany.
Labor Conditions, Mechanization and Unrest
In 1886, labor shortages and threats of a strike by white workers had become serious; hop growers founded the California Hop Growers’ Association, and hired Chinese workers. Simultaneously hop labor camp conditions had become "unspeakably bad throughout the state and the pay was equally abysmal" so that by 1899 the Horst Brothers neighboring Durst Ranch's 300 white and a number of Japanese employees quit and went on strike for more pay. To recruit workers Durst launched advertising campaigns not only by making false promises but advertised for at least twice as many workers than they actually needed, with the goal to play one group off against the other, as he admitted before the U.S. Immigration Commission. Horst revolutionized the processing of hops with the invention of his mechanical hop separator, patented 1909 in Elk Grove, California. It picked the hops while discarding the bine and leaves. It produced 25 bales of hops in one day, while an experienced worker picked just two bales in a week, allowing him to bypass the hassles of hiring seasonal labor. Horst continuously invented new hop-related machinery holding at least 14 patents. In the first season that Horst used the new machine, he advertised and kept hop pickers on hand, in case anything went wrong. When the separator proved itself and the pickers were told that there would be no work, the workers went on strike and blocked access to the kilns, halting the harvest. The harvesting process was further developed in 1939 by his son-in-law, Edouard Thys, founder of which, among other industrial parts, manufactured the parts for the portable hop picking machine. Hop production peaked between 1912 and 1916 and plummeted thereafter. On 3 August 1913 became the site of the Wheatland Hop Riot. Until 2009, when Google released a digitized version of the , the Horstville ranch was often confused with the neighboring Durst Ranch. A film produced between 1900 and 1910 entitled , depicts the processing of hops and their shipment to market.
