Portocork America, based in Napa, California, supplies natural cork closures to the North American wine industry. Its product line includes cork stoppers for a range of wines, from high-end still and sparkling varieties to specialized formats such as Twin Top and Neutrocork designed for age-worthy wines. These closures support bottling processes by providing natural sealing options appropriate for different wine styles.
Portocork also hosts NDTECH, a cork screening technology introduced in 2016 intended to eliminate corks with detectable taint at full production scale. The company operates as a small to mid-sized business with a Napa-area footprint and has pursued facility expansion, including plans in 2017 to build a 54,700-square-foot site in the Napa Valley Gateway Business Park.
