在美国，原产地的名称可以是
1.一个州的名字：如果原产地名称是一个州的名字(如加州)，那么葡萄酒中酿酒葡萄必须100%来自这个州。
2.一个郡的名字：郡的名称是一个行政上的细分(如索诺玛郡)，就像一个县。葡萄酒中酿酒葡萄75%必须来自这个郡，原产地名称包含来自2个或2个以上郡时，在标签上要说明所有酿酒葡萄的产区以及每个产区使用酿酒葡萄的百分比。
3.一个美国种植区的名称：如果葡萄酒标签上提及美国种植区，那么葡萄酒中85%的酿酒葡萄必须来自这个区域。美国种植区是由美国政府规定的。一个美国种植区的成立不仅是对这个区域内葡萄酒的品质认可，而且是对这个区域和其他的区域的不同之处的认可，而不是更好的地方。一个美国种植区（如卡梅尔谷）是一个在地理特征方面和周围其他区域的区别，如气候、土壤、海拔、物理特征和一些历史资料。在美国的157个美国种植区中加州就有占了94个。

In the United States, an appellation of origin can be either the name of
1. a state
When the appellation of origin is a state (California for example), 100 percent of the grapes in the wine must come from within the state’s borders.
2. a county (or counties)
The county appellation (Sonoma for example) is a political subdivision, like a pro-vince. at least 75 percent of the grapes in the wine must come from that county. an appellation of origin comprising 2 or no more than 3 counties may be used on the label if all of the grapes were grown in the counties indicated, and the percen-tage of grapes grown in each county is shown.
3. an american Viticultural area (AVA)
If a wine label mentions an AVA, 85 percent of the grapes in that wine must come-from that area. The system of AVAs is regulated by the US government. by approving an area as an AVA, it does not endorse the quality of the wine from that area, it only approves this area as being distinct from other areas, not better. an AVA (Carmel Valley for example) is an area which is distinguished from surrounding areas by geographical features, such as climate, soil, elevation, physical features and sometimes historical data. There are currently 157 AVA’s in the US, 94 of which are in California.

　　美国葡萄种植区的规定并没有规定葡萄酒的制作过程一定要在这些地区。与其它葡萄酒生产国恰恰相反，加州的葡萄酒酿酒师可以自由地选择他们认为适合种植区种植的各种酿酒葡萄品种（这种理念在加州被充分的运用），可以在他们认为需要的时候灌溉葡萄园，可以在他们认为最好的时间进行收割，并且基于他们自己对产品标准和他们消费者的期望品质的基础上确定每公顷的最佳产品。最后，消费者判断酒商的决定是否完全正确。当然政府制定了严格的规章制度确保加州生产高质量的葡萄酒，比如制作成成品制度(在加州，发酵过中是严禁加糖)，葡萄园杀虫剂的使用，卫生手续等。

　　AVA regulations do not prescribe wine making practices in these areas. Contrary to some other wine producing countries, the winemaker in California is free to plant the varietals he thinks are best suited for a speciic area (the concept of terroir is well understood in California), can irrigate his vineyards if he or she thinks it is ne-cessary, can harvest his grapes when they are at their best, and can determine the optimal production per hectare, based on his or her own quality standards and quality expectations of his customers. Ultimately, it is the consumer who decides if the winemaker made all the right decisions. There are of course strict government regulations governing the production of wine in California to guarantee high qua-lity, such as regulations about chaptalizing (addition of sugar during fermentation is not allowed in California), the use of pesticides in the vineyards, sanitation pro-cedures, etc.

　　加州的94个种植区的列表在18页，具体的地理位置见19页，作为一个种植区它的面积、建立的年代、区域都要经美国政府论证。地图由 Vestra Resources 提供，各个种植区的边界是2005年6月划分的。
　　

The 94 AVAs that currently exist in California are listed on page 18, along with their location on the map on page 19, their size and the year the region was approved by the government as an american Viticultural area. The map was produced by Vestra Resources (www.vestra.com). The AVA boundaries are current as of June 2005.
