Jack & Ann Seifrick

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

Ashley Herzberg, Winemaker

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.

Kelsey Malinzak

Kelsey Malinzak, Cellar Master

Kelsey has been making wine for over 6 years all over the world – from New Zealand to California, to Australia, to Japan, and now back in her home state of California. She has spent much of her career in cellars and laboratories, but she has also made guest appearances in vineyards and tasting rooms which has facilitated her growth and knowledge. Her curiosity has only gained momentum over the years, and a few other places she is looking forward to exploring are Italy, South Africa, Chile, Hungary, Austria, and Portugal, but she has not crossed those off her list…yet!

She is excited to work with us at CAST and to learn more about our Dry Creek Valley microclimate and the varietals we make wine from. She finds our experimental perspective and search for the best grower vineyard sites a great undertaking, a fun approach to making wine, and special way to connect with the greater wine scene. Kelsey loves her career in the wine industry because she finds working with her senses and hands fulfilling and dynamic. She especially loves the sense of community and common ground you can find around a bottle of wine.

In her spare time, she loves to cook and bake new and familiar dishes with seasonal produce from the many farmer’s markets in Sonoma County, catch live music, visit art museums, picnic just about anywhere, backcountry camp, swim, and spend time in her ceramic’s studio.

If you ever see her on the grounds or when the cellar door is open on the terrace, come say hi – she loves talking wine and just about everything else!

Juan Soriano

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.

Barrett Eichstaedt

Barrett Eichstaedt, Operations Manager

Barrett has over 15 years’ experience in the Sonoma County food and wine industry beginning in wine shops and into winery tasting rooms, production, cellar work, compliance, reporting, and management.

As a restaurant General Manager, he experienced the challenges of enterprise operations and an alternate perspective of the wine business interfacing with many small producers, designing wine cocktails, and carefully curating wine lists. This history reflects his passion for food & wine pairings and love of cooking and fine cuisine.

Barrett holds a bachelor’s degree in Business Administration concentrated on operations and supply chain management and will soon complete an MBA focused on project management. Barrett is a native of Northern California, born in San Francisco and residing in Sonoma County for more than fifteen years. He has diverse experience including professional PADI divemaster and rescue diver certifications and years working for LucasArts in the videogame industry.
