About the Plummer Vineyard

The Plummer Vineyard property was originally developed in 2002 on part of a larger estate which had previously been fallowed in the federal agricultural preserve program.  The terrain of the area selected for initial planting varies from modestly- to steeply-sloped with much of the planting on southwest-facing slopes.  Soils in the planted area are variable, as is common to the Paso Robles area, and include Arbuckle-Positas and San Ysidro/Rincon loam complexes.  The original planting of Petite Sirah, Merlot, Cabernet Sauvignon and Syrah was done with 8 foot row spacing and 6 foot vine spacing, designed for bi-lateral cordon training with a Vertical Shoot Positioned (VSP) trellis system.  The Cabernet Franc planting was done in 2005, using the same 8 foot by 6 foot spacing and trellis system, replacing the Syrah block.

The 2002 and 2005 development was planted with a WSW to ENE row orientation, selected to reduce fruit exposure to direct sunlight during veraison.  This unique row orientation has successfully reduced fruit sunburn and allows harvest “hang time” flexibility.  Wines from Plummer Vineyard fruit have consistently shown intense color and good acidity/tannin balance.

In 2013, Plummer Vineyard planted an additional 25 acres of Cabernet Sauvignon (clones 07, 191 & 337) on a steeply-sloped area of the estate.  These vines were planted on a 9 foot row spacing with 5 foot vine spacing, designed for a “California sprawl” canopy.  Where feasible, the WSW to ENE was maintained.

The vineyard is professionally farmed by Vineyard Professional Services with significant input from the vineyard owners, who reside on the property.  Sustainable farming practices are consistently maintained and the overall operation is being reviewed for certification as a sustainable vineyard.
