General Information

The Napa Valley Vineyard Technical Group (Vit Tech) is a non-profit association of vineyardists. 

Management of the group is vested in a five-person Executive Committee elected in December from the regular membership on a staggered term basis for a period of 2 years.

We meet regularly to increase the availability of technical information, provide aid in solving technical problems and to foster good will and fellowship among members.

From November to June, seminars are held on the first Wednesday of the month, from 11 am to 12 noon.

Seminars are open TO MEMBERS ONLY. Per our bylaws, membership is limited to those who are involved in the technical aspects of grape-growing.
