Mansfield-Dunne is a grower-producer of Santa Lucia Highlands wines. Only by owning our vineyards and meticulous organic farming, are we able to represent the true essence of the Santa Lucia Highlands — for us it truly starts in the vineyard.

Two vineyards, one dream

Our two estate vineyards — Peterson Vineyard and Cortada Alta Vineyard — showcase the span of possibilities in the Santa Lucia Highlands appellation. Both vineyards share terroir, yet express themselves completely differently. It is the promise of showcasing this range of possibilities and crafting world-class winemaking that drives Mansfield-Dunne.

Our high-elevation vineyard is the highest vineyard in the AVA, producing deep wines of structure and intensity. Planted in 2014, the best of Cortada Alta is yet to come.

Our namesake vineyard, Peterson Vineyard is a low-lying vineyard that runs alongside River Road. Peterson is well-known for producing wines of aromatic intensity and elegance.

Our Vineyards

Our two estate vineyards show the breadth
of possibilities in the Santa Lucia Highlands.

Since 2011, we have been producing estate Pinot Noir from Peterson Vineyard and have added additional wines from Peterson and Cortada Alta as nature and vineyard development have allowed. Our Single Vineyard wines provide age-worthy expressions of what the Santa Lucia Highlands are capable of, while our Appellation wines show how our two single vineyards compliment each other. The full range of wines is driven by a desire to showcase what grows best in the Santa Lucia Highlands and the range of the appellation.
