Dr. Stephen Krebs has announced his retirement after the Spring 2014 semester.   Both Steve and the program recently celebrated 30 years of providing Viticulture and Winery education at the college.  Steve will still help oversee Summer and the transition into Fall so his contact information is still accurate if you need information on the VWT program.

The Napa Valley College Teaching winery was the first bonded winery in the California Community College System, and we released our inaugural 2008 vintage in the spring of 2009.   Through the support of the college, and the local business community, VWT has built a state-of-the-art program where students can explore all aspects of the industry.
