ETS was established in 1978 to provide the rapidly expanding California Wine Industry with technical assistance and laboratory support. At first, ETS concentrated on microbiological issues and routine chemical analyses. As the industry developed in size and complexity, winery clients looked increasingly to ETS for more advanced analytical services. ETS responded by investing in modern equipment and facilities and hiring highly trained technicians and researchers. This effort allowed ETS clients to benefit from the latest in technological advances. Introducing new technology and developing methods to meet client needs has been a cornerstone of this development process. Today ETS is one of the most advanced wine analysis laboratories in the world.
