Zialena is a modern oasis in Alexander Valley. We offer immersive wine tasting experiences at our stunning estate. Our wines are produced entirely on-site and our concrete fermentation tanks distinguish us. Zialena is named after our Aunt Lena, who was renowned for her hospitality and famous ravioli. It's a family legacy nurtured by siblings Mark and Lisa Mazzoni. Our Geyserville estate has a rich history dating back over a century.
