Solus Sto, Latin for stand alone has been the Haraszthy family motto for many generations. Beginning in 1857, my great-great grandfather, Agoston Haraszthy, helped pioneer the California wine industry. We are dedicated to producing only Zinfandel and stand alone proudly behind this one remarkable grape variety. My family invites you to pour a glass of our Amador County Zinfandel and enjoy a taste of history. I think my great-great grandfather would approve. - Valleys Haraszthy, Haraszthy Family Cellars.
