An American Viticultural Area (AVA) is a designated wine grape growing region in the United States distinguishable by geographic features, with boundaries defined by the Alcohol and Tobacco Tax and Trade Bureau (TTB), United States Department of the Treasury.
AVA’s range in size from the Upper Mississippi Valley AVA at 29,900 square miles across four states, to the Cole Ranch AVA in Mendocino County, CA, at only 62 acres. The Augusta AVA near the town of Augusta, Missouri, was the first recognized AVA, in 1980.
Unlike most European wine appellations of origin, an AVA specifies only a geographical location from which at least 85% of the grapes used to make a wine must have been grown.
The first benefit is to the grape grower. An AVA defines the characteristics of an area. The grower within the AVA will have more of a story to tell. The AVA allows the grower to define his or her story and tie it to his property.
The second benefit is for the winery that uses grapes from the AVA.
With the winery, the message or story is increased and the winery can use it to distinguish itself from other wineries.
The consumer gets the third benefit: people like to know where the wine comes from not only from a safety and sustainability aspect, but also about the unique characteristics that define the grapes grown in a particular AVA.”
Finally, wine and grapes are about location, they speak of the soil from which they grew.

A petition was prepared and filed with the TTB to establish a New AVA to be named “Lamorinda”.
“Viticulture” is the science, production and study of grapes.
The area described (Lamorinda) includes nearly 139 acres (at application date) of planted vines and planned plantings.
The following Unique Characteristics of the area were cited:
