Jack & Ann Seifrick, Proprietors
One evening back in 2011, our founders were searching for the perfect plot of land to open their new winery. Sitting with a bottle of wine, watching the sunset over the vineyards of a lush site in Dry Creek Valley, the group found themselves spellbound by the scenery – and the name “CAST” was born. Nine years and thousands of bottles later (produced; not consumed), the sight still stops us in our tracks. And when you visit, we know it’ll do the same to you.

Ashley Herzberg, Winemaker
Ashley Herzberg, believes that creative explorations in traditional, as well as novel, wines promote connections between classic and emerging wine enthusiasts. Leveraging her chemical engineering background and more than 15 years of winemaking experience, she encourages new techniques that explore the variety of world-class fruit available here in Sonoma County.
Ashley graduated from the University of Nevada, Reno with a degree in Chemical Engineering and the intention to go to medical school. After discovering that her passion was not in medicine, she decided to come to Sonoma County and work a harvest in a winery lab. One harvest quickly turned into an all-encompassing passion and love of winemaking with all the science, art, chemistry, engineering and fun behind it!
She started as a Lab Technician at Owl Ridge and then moved to Lab Manager, benefiting from valuable mentoring by some of the top Pinot Noir vintners in California such as Merry Edwards, Greg Lafollette, Anthony Austin and Scot Covington. Because it was a custom-crush facility with over 40 clients at the time, Owl Ridge provided her with the opportunity to gain the perspective and knowledge that would prove invaluable in her career.
In 2007 she became Enologist and then Assistant Winemaker at Mauritson Winery. She branched out on her own as a consulting winemaker in 2011, making wine for small family owned wineries in Sonoma County. Winemaking isn’t just a job for her; it’s her life. Her two young children are generally traipsing right behind her as she samples vineyard blocks. She loves to garden, cook and travel to wine regions all over the world in her spare time.

Juan Soriano, Farming Director
Nobody at CAST has been here longer than Juan Soriano. We’d love to clone him a few times! He’s quite literally one of the most versatile and conscientious contributors on our team. Originally from the Oaxaca region of Mexico, Juan returns to visit his 100 year old mother there each year. Juan began work with CAST helping crush our very first vintage in 2012, before we even had a winery. He joined the construction crew to help build our facilities, then served as cellar assistant, master gardener and now oversees our Grey Palm Vineyard, where he literally tends to each vine by hand multiple times throughout the season. It’s a family affair as well, with Juan’s wife Berta and daughters all having participated in various capacities at CAST. You will know Juan when you see him – he’s the one in purple, working tirelessly, always with a happy smile.
