1883 Concannon Margaux Mother Vine Vineyard

The 1883 Concannon Margaux, Mother Vine Vineyard is one of the most treasured Cabernet Sauvignon vineyards in California and the only vineyard of its kind in America. This 1883 vineyard is home to extremely rare, Concannon Margaux heritage clones propagated from extraordinary Cabernet Sauvignon that James Concannon imported from Bordeaux’s First Growth, Château Margaux in 1893.

The “Concannon Mother Vine”Mother Vine

In 1965, Jim Concannon and UC Davis selected three cuttings from this single vine which provided the original plant material for the Concannon Cabernet Clones 7, 8, 11. Today, an estimated 80% of California’s 90,000 acres of Cabernet are planted to the Concannon Clones which descended from this one special vine that is still producing beautiful fruit.

“I believe it is entirely fair to say that through the collaborative efforts of UC Davis and Concannon Vineyard to safeguard the Concannon Clones, we have made a highly significant contribution that helped build the extraordinary success of the California Cabernet Sauvignon winemaking industry.”

-Deborah A. Golino, PhD, Director, Foundation Plant Services, UC Davis

Preservation of the Historic, 1883 Winery


Over the course of our ten-year estate revitalization project, we carefully restored our original winery, a California Registered Historical Landmark, which now includes our Tasting Room, Wine Library and Club Rooms.


Every effort was made to utilize all the original materials in its sustainable preservation and restoration:

  • Original brick surrounds the doors, building edges and fountain.
  • The original Spanish mission bell was refurbished.
  • The smaller, milled wood planks are from antique, Redwood barrels.
  • The large timber outside is century-old, pecky cedar wood from the original winery ceiling and upstairs floor.
  • The outside rock walls were built from rocks found in the very rocky soil of the estate.
  • Antique, “Livermore” oven bricks are featured in the fountain base. (discovered during the renovation)
  • Horse shoe impressions were preserved ― a sign of good luck ever since the winery was founded ― as well as an authentic reminder of the important role horses have played in our pioneer winegrowing, family history and Livermore Valley culture and community.

Dedication of the Concannon History Gallery


On July 25, 2016, John Concannon dedicated the new Concannon History Gallery as a tribute to his father, Jim, on his 85th Birthday.

We invite our guests to grab a glass of wine and enjoy a fun opportunity to time travel through Concannon and California wine history — from its beginnings in 1883 to Prohibition, to the creation of the Concannon Cabernet Clones to the Judgment of Paris, and to the remarkable, present day discoveries in sustainable winegrowing.

Our Concannon History Gallery includes:

A New “Concannon Story Timeline”

Our Concannon Story Timeline showcases 19th century and early 20th century Concannon wine pioneer photos along with extremely rare, Prohibition-dated, Concannon wine bottles that mark important milestones in both Concannon’s and California’s wine histories.

HistoricThree of these rare, Prohibition-dated bottles of Concannon wines on display are also now at home in the National Museum of American History, Smithsonian collection.

Captain Joe Concannon, second generation, introduced America’s First Varietal Wine Label with one of these wines: his 1925 bottling of Riesling as a varietal wine. The introduction of labeling wines using varietal names was a great leap forward for California wines, and this same 1925 Riesling now resides in our Concannon History Gallery as well as in the Smithsonian collection.
