Jeff Cohn Cellars

Jeff Cohn Cellars Story 

Jeff Cohn Cellars is a family affair. Jeff and Alexandra Cohn recently moved to Windsor after living in Alameda with their two daughters Isabel and Haley and dog, Riley.

We met in 1987 and got married in 1991. We share a passion for running our boutique 5,000 case Sonoma winery as a team. Jeff crushes the grapes and Alexandra crunches the numbers. We established Jeff Cohn Cellars in 1996 with just a few labels, expanding to what is now a Rhône-centric and single vineyard Zinfandel winery with an average of 20 wines produced each vintage. 

From Bowie to Sonoma

Growing up in a relatively small town of Bowie, MD, Jeff is the son of Iris and Elliott Cohn. “My father worked very hard to provide for us and my mother was without a doubt one of the most wonderful people I have ever known. She was kind to a fault, always thinking of others before herself. My goal has always been to make them proud of me.” With support like that, and immense ambition, Jeff was destined for success.

Long before his winemaking aspirations, Jeff attended Johnson & Wales University in Rhode Island, earning his associates degree in Culinary Arts. From there he ventured to Florida International University to earn a bachelor’s degree in Hospitality Management. Jeff loves the hospitality industry, and as many do, found his passion for wine as he worked through several high-profile positions, including the Hyatt Regency Crystal City in Virginia.

In a twist of fate, Jeff and Alexandra met while working at the Hyatt. Jeff was the F&B Cost Controller, while Alexandra was an accounting trainee making her way through the departments in the hotel for training. That included working in Jeff’s department for three weeks where she and Jeff got to know each other better.

We had both graduated from Florida International University, but our paths never crossed there. It was at our orientation at the Hyatt, and through mutual friends at the hotel, one of which also attended FIU, they we frequently spent pur time off together, alone and with our friends playing cards, going on road trips, and enjoying each other’s company. This is where our story of Jeff and Alexandra’s great adventure together begins …

The more Jeff was exposed to wine; the more he strove to learn more to feed his passion. The idea of becoming a winemaker was being nurtured. Starting as an intern at Boordy Vineyards in Maryland, he drove an hour and a half each way to prune in frigid weather, pick grapes in stifling heat, and scrub everything from barrels to floors. The job at Boordy was a defining moment as Jeff was on the road to his dream destination.

With the support and encouragement of our families, we moved to California in 1993. Alexandra went to work in finance, while Jeff earned his master’s degree in Agriculture Chemistry with an emphasis in Enology from Fresno State in 1996. Jeff’s exposure to French winemaking techniques and the concept of terroir was enlightening and ultimately influenced his focus on Rhônes. “The flavor profile was so different than anything I had ever tried,” he says of the first Châteauneuf-du-Pape that he tasted in school. “It was a shocker. To go from tasting only single varietals to a complex blend really opened my eyes.”

After graduating, Jeff joined Kent Rosenblum at Rosenblum Cellars as the Enologist. He rapidly moved beyond lab work and soon found himself in charge of the entire white wine program. In 2000, Jeff was promoted to head winemaker, and in 2004 was named vice president of winemaking and production. Jeff was instrumental in creating cutting-edge barrel and yeast programs that took Rosenblum’s wines to a whole new level. It was through experimenting at Rosenblum that Jeff perfected the technique of using different types of yeast to create even more subtle, specific characteristics in the wine he was crafting. At the same time, Jeff was making small production wines under his own label JC Cellars

Jeff produced the first California Zinfandel to hit the top 10 of the Wine Spectator’s Top 100 list. The 2003 Rosenblum Rockpile Road Zinfandel was rated #3 on the 2005 list. This was not only a coup for Jeff Cohn and Rosenblum; it was an amazing accomplishment for the California wine industry. It was then, in 2006, Jeff departed Rosenblum Cellars to focus on his own winery, and consulting for many other wineries along the way, including some of our growers from which we source our grapes.

JC Cellars was one of the original urban wineries in the East Bay with both winemaking and a tasting room space near downtown Oakland. As the production grew, our wines were distributed in select markets nationwide for restaurant and retail sale. Jeff was making wine while Alexandra jumped on the road to work trade shows, establish distributor relationships, and sell wine to retail stores and restaurants, all while balancing being a mom to two beautiful girls, and growing the sales of our winery.  

In 2012, we made another important decision to change the name of the winery to Jeff Cohn Cellars.  As Jeff explains, “our winery and our acclaim from the wine writers have just exploded since then.” A simple name change launched the recognition that the winemaker gracing the pages of the Wine Spectator and Robert Parker’s Wine Advocate, who had established such a presence through his work at Rosenblum, had my own namesake winery. People sought out the wines with fervor. The Robert Parker scores for the 2014 vintage ranged from 99 to 90 points for 18 of the 22 wines produced. That was perfect timing for another incredible transition that came in the spring of 2017— “we’re coming home to the vineyards of Sonoma.”

Our tasting room is now located in the heart of the historic Sonoma Plaza, with our winery operation just a short 20 miles away in Santa Rosa. This was an exciting time for us to make this move from urban winery to a Sonoma Valley winery. We will always love our Easy Bay community, but this move was the next step in the evolution of our winery.

We source over 85% of our grapes from Sonoma County. It’s a special place with so much diversity in elevations, climate, soils, terroir, and the numerous grape varietals that thrive here. It’s not too cool, not too warm, it’s just right for Jeff’s winemaking style. Our growers have been part of our extended family for many years. It’s a community of like-minded people who don’t so much compete, as they complement each other. We are proud to be home in Sonoma. 

Passion. Pride. Place.

Jeff’s winemaking style continues to evolve  but there are three core concepts that he follows year after year: Make the best wine possible from the highest quality fruit, and from the vineyards that showcase the terroir and unique character that sets our wines apart.

Our passion for finding rocky, hillside vineyards that produced a sense of minerality set us on the course for what is now Jeff Cohn Cellars.

We look for fruit that comes from exceptional vineyards so that we can make exceptional wines. We love vineyards that are rocky and steep, as these types of vineyards produce fruit which leads to concentrated wines bursting with flavor.

From alternative fermentation techniques like a concrete egg, larger format French oak barrels, concrete Foudre, terra cotta amphora, to yeast selections that will best suit the character that he wants to coax out of the wine, Jeff takes no shortcuts. Barrel by barrel the wines are nurtured to express the passion that drives his thirst for excellence, the pride of putting the best wine in the bottle, and the sense of place expressed as a primary characteristic in each and every wine.  

Harvest is Jeff’s favorite time of the year. You may see him touring around in his purple “Oh Grape” Mini-Cooper from vineyard to vineyard checking grapes.

He goes against the grain. The numbers may say it’s time, but it’s Jeff’s palate that says when the grapes are ready. We are fortunate to have growers that respect Jeff’s integrity and trust his winemaking. Those relationships allow us to produce wines, vintage to vintage, that highlight Jeff’s passion. He shares it with the winemaking community through moderating winemaker panels, oak symposiums and consulting for other wineries. Giving back to the community is important to us.

Our Family


Jeff’s mother, Iris is an integral part of our story as a winery. A beautiful Iris adorns our label to show that she offered the support that gave Jeff the opportunity to follow his dream. When we decided to start the winery, Iris provided us the capital that allowed Jeff to follow his passion. If not for her, none of this would have been possible. “The Iris on the label is a constant reminder that my mother, Iris. She is celebrated and recognized in every wine we make.” It’s a beautiful tribute to a strong, beautiful woman. 


While Jeff is the artist who creates our “vinous elixirs” as Robert M. Parker, Jr., calls them, Alexandra is the glue that binds our team, and the Jeff Cohn family. “Ask Alexandra,” can be heard every day at the tasting room, office, and winery.

She knows the business inside and out. From production to accounting, Alexandra seamlessly changes her hats like a performer changes costumes. She is an accountant by trade, managing all financial aspects of the business, but she’s no bean counter.

Her creativity shines through in all that we do. From label designs, marketing, and wine club administration to tasting room design, event coordination, and managing sales, you can see Alexandra’s mark on everything that we do. Her favorite job is being a wife and mother. She loves to cook, bake, and entertain in between carpooling, taking care of the girls, and training Riley. Creative, crafty, and has more energy than the rest of the team put together. Her enthusiasm is contagious, encouraging us all to think outside of the box while not reinventing the wheel. 


JC Cellars became well known for some unique offerings starting with their Rhodes Vineyard Zinfandel which was ready to harvest on the day that their first daughter Isabel was born and then again on her first birthday. Since then, Isabel’s name adorns a Zinfandel label each vintage.

She is easy-going, loves to laugh and her smile lights up the room, but as any young woman making ther way through this world, she does have her darker moments. “I liken my Zinfandel to her personality, vibrant and fresh, sunshine in a bottle, but also has a little darkness or depth to make it intriguing and interesting.” Currently Isabel’s name adorns the 2017 Sweetwater Springs Zinfandel.

Isabel can be found some days on the road driving around with her Dad to check on the vines as they mature. Currently attending Berkeley City College, she went to Portland in the fall of 2018 to study Graphic Design and Music. She is a very talented guitar player and as a teen, dedicated time and efforts receiving her Girl Scout Gold Award by raising money for instruments and giving guitar lessons to budding musicians at the Boys and Girls Club of Alameda.


Jeff and Alexandra’s youngest daughter Haley’s name adorns our flagship Rockpile Vineyard Syrah. Jeff and the Rockpile Vineyard have a long, loving friendship with some rocky moments, sometimes like Haley. “She is a bit hard headed and determined, insistent on doing things her way. Yet, she too has a soft and generous side not unlike the Rockpile Syrah which has many layers and complexities, just like Haley.” She gradulated high school as part of the 'Rona Class of 2020, has started collage and continues to spreads her artistic wings through drawing and watercolor painting. 

Wine Dog - Riley

The latest addition to our family is our Irish Terrier, Riley. She has big shoes to fill afer we said goodbye to our beloved Welsh Terrier, Abby but now that Riley has matured, she has become part of our winery team. 

The French Connection

While at Rosenblum, Jeff was making a few wines each vintage under his JC Cellars, beginning in 1996. As his love of the Rhônes continued, he focused on learning from some of the finest winemakers from the Northern Rhône. In 1998 at Hospice du Rhône, Jeff found himself on the bowling team with some of his winemaking idols from Côte-Rôtie, St. Joseph, and Condrieu. They bowled, they drank wine, and they collaborated, and shared their passion. This transformed the resources with which Jeff surrounded himself, creating what we fondly refer to as our French Connection.

A person of passion seeks out others of passion. To date, Jeff has made wine with Pierre Gaillard, Francois Villard, Yves Gangloff, and Yves Cuilleron. Our current projects include Stagecoach Viognier “2 Guys 2 Barrels” made with Yves Gangloff. Jeff loves Condrieu that shows a sense of mineral backbone.  When Viognier from Stagecoach became available Jeff called his friend Yves and asked if he would like to work together. The result has been an amazing Viognier that showcases the Stagecoach fruit, while imparting French winemaking techniques that take it to another level. Yves’ son Loup even designed the label which is unique and classy, without being too serious. 

Yves Cuilleron is the connection for our latest project “Domaine des Chirats” Rockpile Vineyard Syrah. The second vintage of this wine was just magical. Elegant is not a descriptor oft used for wines from Rockpile, but if a wine this bold can be elegant, this one is. The minerality is stunning and showcases the native yeast that Jeff isolated from Rockpile while working for Rosenblum. It adds finesse to our Rockpile Syrahs that is so unique; it’s hard to believe you are drinking a California Syrah. Jeff and Yves find the perfect balance between bold California fruit and French sophistication. 

A family winery requires long days, dedication and lots of hard work. The rewards are worth it. “When your phone is ringing off the hook, and the inbox is full of orders for the wines that you have put your heart and soul into, it is a very bright spot that reminds us why the occasional sacrifices are balanced by the pride of producing wines with integrity that are enjoyed by our extended winery family.”

We invite you to come and share the experience of being a part of the Jeff Cohn Cellars winery family where “anything is possible.”

Cheers!  & Half Full ~

Alexandra & Jeff Cohn
