This January, Castello President Georg Salzner and Winemaker Peter Velleno planted our first cork tree. Native to southwestern Europe, the Quercus suber cork oak tree can grow up to 100 feet tall, and is sure to thrive in the Mediterranean climate we enjoy here in Napa Valley.
Wine Corks are made from the bark of the cork tree, which needs to be stripped and peeled off by hand. Cork trees are typically harvested every seven years, and are a renewable resource since the tree is not cut down and only the outer layer of bark is removed. It takes a cork tree 25 years to reach maturity before its bark can be harvested, and we are looking forward to our first Castello cork harvest in 2042!
