Since 1978, ETS Laboratories has supported the art and science of winemaking. As a family-owned, locally operated laboratory serving Napa Valley and wine regions beyond, we combine technical expertise with a long-standing commitment to the growers and wineries we work alongside.
ETS is ISO/IEC 17025 accredited and provides a comprehensive range of analytical services to support every stage of the winemaking process, from grape to glass. We continually reinvest in state-of-the-art instrumentation and emerging technologies to help address industry challenges while maintaining the accuracy and reliability our clients depend on.
For decades, wineries have relied on ETS for responsive service, dependable turnaround times, and results they can trust. Through educational resources and technical engagement, we remain committed to strengthening the broader winemaking community.
Our focus remains simple: continuous improvement in the science and service that support great wine, today and for generations to come.
