The Original Hop Yard, in Pleasanton, California, is located on what was once the largest hop farm in the world. From the 1880's to the beginning of World War I, the Pleasanton Hop Company operated on nearly 1900 acres of swampy marshland along what is now Hopyard Road. The fields began about a half mile west of downtown and extended north for over one mile. At harvest time, more than one thousand men, women and children would gather in Pleasanton to pick hops for about a penny per pound. Most of the hops were exported to London, where they commanded the highest premium.
