Mourtaou Selections available from FPS

  Mourtaou 01.1
Registration Status Provisional
Protocol 2010 Qualifies for Protocol 2010. (This selection planted in Russell Ranch)
Source Whitten Ranch vineyard, Geyserville, California (Alexander Valley appellation)
Treatments Microshoot tip tissue culture therapy
Comments This selection came to Foundation Plant Services in 2013 from well-respected viticulturist David Gates, Vice President, Vineyard Operations, Ridge Vineyards, in Sonoma County, California. This cultivar is one of four (Petit Bouschet, Béclan, Mourtaou, and Saint Macaire) harvested from the old vineyards at Whitten Ranch in Geyserville, California. The vineyards at Whitten Ranch were planted in 1882 (Old Patch) and 1891 (Old Carignane) by A. Boutin, an orchardist and colleague of Luther Burbank. Boutin named his estate Heart’s Desire. Gates indicates that the surviving vines in the old vineyards are a field blend of Carignane (35%), Zinfandel (26%), Alicante Bouschet/Petite Bouschet/Grand noir (19%), Mataró (9%), Syrah/Petit Sirah (7%), and other, including Grenache, Négrette/Pinot St. George, Béclan noir, Listán, Olivette noir/Cornichon, Mourtaou and St. Macaire (4%). Ridge has made wines from these grapes since 1966. Gates is of the opinion that the clones could have value for the wine industry. All four cultivars have been donated to the FPS public grapevine collection. Mourtaou 01.1 underwent microshoot tip tissue culture therapy at FPS in 2013 and qualified for the Russell Ranch Foundation Vineyard in 2017.

  Mourtaou 02.1
Registration Status Provisional
Protocol 2010 Qualifies for Protocol 2010. (This selection planted in Russell Ranch)
Source Lytton Estate, Dry Creek Valley, Sonoma County, California
Treatments Microshoot tip tissue culture therapy
Comments This California heritage clone came to the public grapevine collection at Foundation Plant Services in 2014 from well-respected viticulturist David Gates, Vice President, Vineyard Operations, Ridge Vineyards, in Sonoma County, California. The historic Lytton Springs property in the Dry Creek Valley in Sonoma County was originally developed by Captain William Lytton, who built a hotel and spa resort on the property in the last half of the 19th century. The Syrah vine from which this selection was collected was planted in 1901 on the old Lytton Estate property. Ridge Vineyards purchased the vineyard many years later. The original material donated to FPS underwent microshoot tip tissue culture therapy and qualified for the Russell Ranch Foundation Vineyard in 2017.
