Olmo grapes

Dr Harold Olmo

Olmo grapes are

cultivars of different Vitis
species.

Over 30 new grape varieties were created by Dr. Olmo and introduced to the California wine and table grape industries.[1]

Ruby Cabernet

body to produce premium wines.[2]

In California, the variety is widely planted in the

South Africa
.

Rubired

Rubired is a hybrid of the vinifera variety

Tinto Cão and Alicante Ganzin, which itself is a hybrid of Vitis rupestris Armon Rupestris Ganzin No. 4 and the vinifera crossing Alicante Bouschet. Trial breeding and testing were completed by Olmo in 1958.[2]

Like Ruby Cabernet, it was bred to produce significant

varietal wines.[2]

Emerald Riesling

Emerald Riesling is a white wine grape crossing between the vinifera varieties

Germany at facilities like Geisenheim Grape Breeding Institute, the Emerald Riesling was bred for warm climates like the San Joaquin Valley of California where today more than half of all Emerald Riesling plantings are found. Outside of California, there are limited plantings in South Africa.[2] It is also used quite extensively in Israel, where big wineries use it to produce light, and aromatic - usually off-dry - wines. It comprises roughly 2.6% of the total grape production in Israel, totaling (in 2012) 1,408 tons.[3]

According to wine expert Jancis Robinson, Emerald Riesling produces an aromatic, high

acid wine that doesn't quite have the flavor definition more commonly associated with Riesling or its cool climate crossings. In cooler climate areas where it has been planted, such as the Monterey AVA, it can share some traits with Riesling but with a distinctly fuller body.[2]

Emerald Riesling is also known under the synonyms California 1139 E 29, Emerald Rizling, and Riesling Izumrudnii.[4]

Other wine grapes

Dr. Olmo frequently used Carignan (pictured) in his crossings.
  • Carnelian is a crossing of the Vitis vinifera Carignan and a separate vinifera crossing between Cabernet Sauvignon and Grenache. It was created in 1972 to combine the genetic traits that allow Carignan and Grenache to produce well in warm climates with some of flavor and wine characteristics of Cabernet Sauvignon.[1]
  • Centurian (also known as Centurion) is a vinifera crossing between Carignan and a separate crossing of Cabernet Sauvignon and Grenache. The grape was developed by Dr Olmo in 1975 matching the same grape varieties used to produce the Carnelian grape a few years earlier. Today it is mostly planted in the Central Valley of California.[5]
  • Semillon and Gewürztraminer, that was created in 1938 by Dr. Olmo at the California Agricultural Experiment Station.[6][7] A separate red Flora hybrid exist but it is not related in any way to the Olmo Flora.[8]
  • Royalty is a crossing of the Vitis vinifera Trousseau gris variety from the Jura wine region of France and the teinturier grape Alicante Ganzin that, itself, is a hybrid of a Vitis rupestris variety and the Vitis vinifera grape Aramon.[9] The variety was first developed in 1938 but wasn't released for commercial use until 1958 when it was released with Rubired.[10]
  • Symphony is a crossing of the vinifera varieties
    aromas of citrus, apricot and peach. It is primarily a blending grape but can be made into a varietal
    wine.
