Welcome to the world of winemaking, where science meets art, and passion is the driving force.

—Tom Rochioli, Winemaker/Owner, J. Rochioli Vineyards and Winery

“Over the years, we worked closely together to get the grapes harvested to her tight standards while always having enough flexibility to make the hectic harvest as smooth as possible. Theresa possesses a deep understanding of viticulture and the wine making process and knows how to handle the ever changing conditions of grape growing.

She consistently produces high-quality wines in many varieties. Working with our fruit, she has produced some of the best examples of Russian River Chardonnay and Pinot Noir wines that have been produced from our vineyard.”

—Kent Ritchie, Grape Grower/Vineyard Owner, Ritchie Vineyard

“I have worked with Theresa for 12 years during her time as winemaker at Gary Farrell Winery, and it has been a real pleasure. A lot of people think I’m a good farmer, but working with great winemakers like Theresa makes me really look good. She’s been working with Chardonnay grapes from my vineyard for over a decade and the wines that she’s produced have been consistently outstanding. Theresa is also very hands-on in the vineyard; she’s out here all the time overseeing the grapes as they mature throughout the growing season. Her hard work and commitment show in the bottle because the wines she produces always turn out excellent. I’m very happy for her about this new adventure that she’s taking in her career. I will miss her very much and I’ve really enjoyed the time that we’ve worked together.”

—Diana Karren, Owner/Grapegrower, Terra de Promissio

“Having worked with Theresa Heredia since 2017, I can attest to her deep knowledge of viticulture and extensive winemaking experience. Her ability to unlock the full potential of a vineyard is truly remarkable. By collaborating closely with us, the grape growers, Theresa has helped cultivate some of the most elegant and balanced Terra de Promissio wines ever produced in Sonoma County. The wines have received exceptional scores and have been sold out every vintage. Theresa is confident in her decisions and unwavering in her vision of producing world-class Pinot Noir. Working alongside someone so dedicated and proficient has been a privilege of a lifetime.”

—John and Pam Bacigalupi, Growers/Vineyard Owners, Bacigalupi Vineyards

“John and I have worked with Theresa for at least two decades. We have had a long and rewarding relationship. She is considerate of us as growers, and tries very hard to accommodate our delivery schedule of grapes from the field to the winery during the craziness of harvest. Her attention to detail as a winemaker and extensive experience make Theresa a person to be trusted with the decision-making process that comes along with starting a wine brand or enhancing an existing one.”

—Kirk Lokka, General Manager, Emeritus Vineyards

“I have worked with Theresa Heredia for over 12 years. I have found her to be a very organized Winemaker who is very good at predicting in advance when grapes will be ready for harvest. She is also very good at communicating her desired schedule for harvest.

I have found that she has an ability to accentuate the finest qualities of the grapes from each vineyard she works with. She will also respectfully express any changes in growing practices without forcing them upon the grower.

I think her wines are very focused and are of the finest quality, consistently. I enjoy her wines often. She is very easy to work with, and enjoyable to talk with.”

—Evan Goldstein, MS

“I have had the privilege and pleasure of working with her for well over a decade and in various capacities. Her myriad award-winning wines speak loudly for themselves but, Theresa is also a brilliant panelist, a formidable educator, and an engaging ambassador. Taking her full quiver of skills and making them available to those who would like to work with her is a gift to all.”

—Virginie Boone, Sonoma County-based wine and spirits writer and critic

“She is gifted with a true science mind and is a meticulous winemaker who spent considerable time in France’s winemaking regions learning, observing and tasting. Theresa is one of the most consistently outstanding makers of high-scoring wines, turning out exceptional wines from a diverse set of vineyards vintage after vintage. Her 2015 Russian River Selection Chardonnay was named Wine Enthusiast’s Number One wine in 2017. It’s not every day you find these qualities in one person – keen intellect, hard work ethic, curiosity and open-mindedness with an ability to mentor even from afar. California is lucky to have her in our ranks.”

—Melissa Stackhouse, Winemaker, Dutton Goldfield Winery

“Theresa possesses all three of these characteristics, and then some. I am intrigued by her expertise in directing and communicating her vision while at the same time remaining flexible and extremely personable. The passion & love that Theresa brings to her craft not only produces spectacular wines but motivates us all to work together as a team for her. I admire Theresa’s ability to provide leadership, explain the why behind doing something a certain way, and attentive focus on the details. Making wine with Theresa has been such a rewarding experience for me and I am excited to see what she does next!”

—Nancy Bailey, General Manager, Hamel Family Wines

“I worked closely with Theresa for 11 years while I was General Manager at Gary Farrell Winery. Her improvements in winemaking imparted textural richness and sensorial nuances to each bottling, and captured site-specificity in our single vineyard offerings, resulting in widespread acclaim from consumers, trade and media.

Theresa is an exceptional leader. She brings great depth and breadth of knowledge and experience, but tends to lead from the middle, encouraging her team to grow. Her dedication and enthusiasm towards her craft is infectious, inspiring her colleagues. She is also an exceptional communicator, making her an exceedingly effective brand ambassador with members, consumers, trade and media. I cannot recommend Theresa Heredia highly enough.”

—Craig Williams, X Novo LLC

“Ms. Heredia is a warm, engaging individual who teaches others by example, is inclusive, and exhibits a curiosity and motivation to improve quality. Theresa’s innovative winemaking techniques, combined with her profound respect for the land and environment, resulted in wines of exceptional complexity, balance and length. Under her guidance, Gary Farrell Vineyards and Winery garnered accolades and recognition, cementing its reputation as one of the premier producers of cool-climate wines in the country.”
