Welcome to Zialena Winery – a fourth generation winery in the heart of Alexander Valley

*** Effective March 16th 2020 due to California Governor order regarding the COVID-19 ***

Our Tasting Room will be closed until further notice. This is in compliance with an order issued by California Governor, Gavin Newsom, on Sunday, March 15. We will also be postponing our Pop-Up Wine Tastings in AZ and TX that are currently scheduled for later this month. Our associates will be working remotely and are available to answer questions about wine orders, winery visits, or any other topic we can help you with. Be well and we look forward to welcoming you back to Zialena once the pandemic is over. 

*** Effective March 12th 2020 due to the Sonoma County Health Advisory regarding the COVID-19 ***

As with any other adverse situations we are prepared to make real-time decisions for our customers, associates and community. Our decisions are based on the guidance provided by our local authorities who in turn are taking guidance from federal and state authorities. As we learn more each day, we want you to know that we are taking immediate steps to minimize the impact of COVID-19.

  • In general, we are and have been following the guidelines from the Centers for Disease Control on personal hygiene and workplace sanitation.
  • Specifically, we are following the Sonoma County Advisory regarding indoor gatherings of more than 50 people.
    • postponing Rose Release Party scheduled for March 21st
    • postponing Industry Event scheduled for March 25th
    • assessing Pop-Up Wine Tastings in AZ & TX
  • Additionally, we will be temporarily moving to appointment-only in order to adequately disinfect between guest visits.
  • Lastly, our associates are empowered to stay home (without economic penalty) if they feel unwell or uncomfortable coming to work. We feel these actions are responsible given the evidence of virus spread today.

As more evidence is collected and guidance is updated, we will adapt accordingly to continue to do our part to minimize the impact of COVID-19 in our community. We will keep our website and social media accounts up to date as the situation evolves.
