The Family

Delmas is the realization of the Robertson family’s dream, 35+ years strong, to honor a particular place; a particular taste. Born of distinctive geology found within The Rocks District of Milton-Freewater as well as the climatic eccentricities of the Walla Walla Valley, Delmas is dedicated to producing exceptional wines of enduring value. Elegance is preferred to power and exoticism at Delmas; restraint, nuance, and those impossible-to-define, (pleasurable), qualities that elevate all great wines.

The name “Delmas” comes from Mary Delmas Robertson’s side of the family. In a tradition dating back many generations, the French family name “Delmas” is passed from one daughter to the next as a middle name. This legacy lives on through Steve and Mary’s daughter, Brooke Delmas Robertson.

Brooke has expanded the family's wine industry partnerships. She has spent the last four years in Napa Valley gaining viticultural, winemaking, and development experience.

World-class positioning is assured via fresh perspecitves regarding farming practices and winemaking at Delmas.

Where It All Started

The family’s love of wine began in 1982 on a trip Steve and Mary took to Napa Valley.

In 1983, they returned to Napa Valley, purchasing a home between St. Helena and Calistoga on 10 acres without ever stepping foot inside the home and without the benefit of jobs at that time. They were smitten and ready for an adventure. Their eldest child, Brooke, was born three years later in 1986.

While in Napa Valley, Mary worked for Wilson-Daniels, an international wine brokerage firm with exclusive U.S. distribution rights to some of the world's most sought after wines – Domaine de la Romanee-Conti and Biondi-Santi as well as many highly regarded Napa Valley wineries.

During this time, the couple’s exposure to the wine industry and winemaking skyrocketed. They were able to get to know many of today’s well-respected leaders who were just getting started at that time and who remain pals today.


Meet the Talent


Mary Delmas Robertson | Director of Sales

Given Mary’s extensive international, national, and regional background in wine marketing, sales and distribution, she’s a natural in leading the Delmas sales effort; focusing primarily on the Direct-to-Consumer channel. 

She has deep “local” knowledge of the market. Mary graduated from the University of Washington.


Brooke Delmas Robertson | Director of Viticulture

Brooke has gained world-class, hands-on experience in Napa Valley, tending to the high expectations of iconic vineyards and wineries. Additionally, Brooke has worked in Australia for Torbreck, focusing on small lots of highly sought after Rhone-style wines. Her last work assignment in Napa Valley was for The Napa Valley Reserve, as viticulturist.

Working as a viticulturist, administering and delivering “best practices” in vineyards such as Hundred Acre, Barbour, Hayne, and Seven Stones, fueled Brooke’s desire to further her education. In this regard, and in preparation for her eventual oversight role at Delmas/SJR Vineyard, Brooke is pursuing her Masters degree in Viticulture.

As of 2017, Brooke has moved back to Walla Walla Valley to assist in all Delmas/SJR operations. Additionally, she is working for North Slope Management as viticulturist.
