The American Viticultural Area has a set of standards to define a wine growing region. There are 230 wine growing regions in the United States. The labeling laws of the AVA are very loose allowing a 1.5% plus or minus from the percentage stated on the label. Wine law defines a State, county, or region must contain at least 75 percent of the grapes from that area. Exceptions would include California and Oregon which must contain 100 percent from their state. It gets even more complex by stating that a designated AVA like Carneros, California must contain a minimum of 85 percent from that district and if it designates a vineyard must contain 95 percent. When two or three grapes are mentioned on the labels the percentage of each grape must appear. "Estate Bottled" means 100 percent of the grapes must come from a single AVA and from the estates own vineyards, or from vineyards owned or controlled by the estate.
