Harold Olmo (July 31, 1909 – June 30, 2006) was an American viticulturist and professor at the University of California, Davis where he created many new grape varieties known today as Olmo grapes. In the 1950s, he helped to establish California's first quarantine facility on the UC Davis campus to permit California growers to import foreign vines. This led to an expansion of California's wine industry as more Vitis vinifera was introduced to the area.
He became an assistant professor of viticulture at UC Davis in 1938. In 1939, he set up a research plot in the Larkmead Vineyards. In 1948, he traveled a total of 12,000 miles in Iran, Iraq, Turkmenistan, Afghanistan and Pakistan to collect seeds and cuttings from the region. He brought it back to the USA, a collection that eventually became UC Davis' collection of genetically-diverse grapes. He also imported cuttings of the Greek varieties assyrtiko and moschofilero in the USA, which were stored at UC Davies until the Abbey of New Clairvaux started cultivating it in 2011.
In 1955, Olmo was in Western Australia studying climatic limitations of viticulture in the Swan Valley. Olmo spent eight months in Western Australia at the invitation of the Western Australian Vine Fruits Research Trust. When he published his report in 1956, one of the recommendations put forward was that Mount Barker and the Frankland of the Great Southern area of Western Australia showed great promise for making table wines in the light traditional European style.
He retired from UC Davies in 1977. He was also a consultant for the United Nations, a Fulbright scholar and a Guggenheim Fellow. He died in 2006, and had patented his last grape a few months before his death. The sum of his work and research is stored at UC Davis, under the file collection number D280, and was digitized for global access in 2020.
Since 2015, Larkmead Vineyards has been releasing the 'Larkmead Dr. Olmo', a 100% Cabernet Sauvignon cru born out of Harold Olmo's 1939 test crops planted on the Vineyards' property.
