About our Wine Caverns:The wine caverns were the first stage in the creation of the Ironstone Vineyards, and served as our first Tasting Room.In 1989, the Kautz family assembled a crew of professional miners including some of the “old timers” that had worked the early gold and gem mines. They blasted, picked, and shoveled their way through 10,000 square feet of limestone and schist rock to form the wine caverns. The project took ten months to complete and on many days the miners would only make two to three feet of progress. The rock was so hard and difficult, they often said it was like blasting through iron. Thus, our name “Ironstone Vineyards.”The caverns hold a maximum of 1,500 French and American oak barrels which each hold sixty gallons of wine. The beautiful wooden doors that grace the entrance to the caverns and the breezeway, as well as the tasting room, are made from 100-year-old redwood fermentation tanks from the Di-Augustini Winery in Plymouth, California.
