Pinot Noir Clone & Size – Do Either Matter?

J. Lohr’s History with Pinot Noir One of original 11 varieties planted in Greenfield in 1972 Selection was from neighbor recommendations Possibly virus infected/champagne clones Viticulture in 1970’s for Pinot Noir was still California sprawl Low color and “rubber boot” aromas Budded over to Riesling and Valdiguié in late 1970’s

ENTAV-INRA Pinot Noir Clones Create Excitement in California

J. Lohr Revisits Pinot Noir in 2003 Quality wines being produced from Dijon clones in cool climate areas Tasted through numerous small lot wines from clones and rootstock combinations from nursery in the Arroyo Seco Selected and planted in 2003 Dijon Pinot Noir clones 115, 667, 777 and 1950’s Pommard 4 on 1103P and 115 and 777 on rootstock in 27 acres of GV 9. In 2008 planted more Pommard 4, 667 and 777 on rootstock in 18 acres of GV 3 Also in 2008, planted 25 acres of clones 115, 777, 828, Pommard 4 and Swan at Escolle Road Vineyard and 42 acres of clones 115, 667, 777, 2A and Pommard 4 at the Costa Vineyard both in the Santa Lucia Highlands AVA
