While America has been producing wine since the 17th century, with the arrival of European settlers, and President Thomas Jefferson was a celebrated expert on the juice of the grape, it could be argued that American winemaking didn’t come into its own until 1979. This was the year the Bureau of Alcohol, Tobacco, and Firearms, now known as the Alcohol and Tobacco Tax and Trade Bureau (TTB), established the American Viticultural Area (AVA) system.

Similar to the appellation systems of Europe like the AOCs of France, DOCGs of Italy, and Grosses Gewächs of Germany, the AVA system delineates and defines wine growing areas to promote a unique identity. That said, the AVA system allows for a degree of freedom in viticulture and winemaking that many of the top-tier Old World wine regions don’t enjoy. The result has been the emergence of regions with signature wine styles across the breadth and depth of the country, as winemakers benefit from creative liberty.

With the nation marking the 250th anniversary of the Declaration of Independence on July 4th, we look at a strand of American history that has won against the odds over the years and emerged triumphant: US wine history and the AVAs.

The TTB describes an AVA as “a delimited grape-growing region with specific geographic or climatic features that distinguish it from the surrounding regions and affect how grapes are grown”. According to TTB regulations, not less than 85% of the wine has to come from grapes grown in the detailed viticultural area.

Such designation on a wine label helps producers to communicate a wine’s quality as a product of one of the official American wine regions. Precise geographic origin information enables consumers to have a better understanding of the wines they’re considering.

For more than two centuries until the 1970s, the US wine industry operated without official rules governing wine label information. If a winery wanted to label a white made from unspecified grape varieties “Chablis” or a fortified wine “Port”, it could – and often did! On the whole, consumers simply didn’t care, which gave little motivation to the government to remedy the situation! The Prohibition years (1920-1933) set the wine industry back even further. It wasn’t until the alcohol ban was lifted that a new generation of wine professionals – from writers to merchants and importers – began to advocate for clear, honest labels inspired by European traditions.

Frank Schoonmaker was one such voice. Long before the Robert Parkers of the world appeared on the wine scene, he was one of America’s earliest wine writers and authorities, advocating for transparent wine labeling at the start of the 1930s. This South Dakotan had lived in Europe and been a protégé of Raymond Baudoin, the editor of La Revue du Vin de France, under whose influence he learnt about French viticulture and wine appellations. He wrote the “Complete Wine Book” (1934) and later “Frank Schoonmaker's Encyclopedia of Wine”, which was something of a bible for wine lovers for years.

However, Schoonmaker was decades ahead of his time. It wasn’t until 1979 that the AVA system was founded and the first designation awarded to, not Napa Valley as is widely assumed, but to Augusta in Missouri (famed for native American and French-American hybrid grapes and Vitis vinifera), in 1980.

What brought this change about? Firstly, a rising interest in wine during the 1960s and 1970s. Secondly, the historic and seminal Judgment of Paris in 1976 when Californian wines defeated French wines at the hands of local wine critics. The time was ripe to establish a formal, government-regulated approach to defining American wine regions and bottle labeling.

In 1981, Napa Valley was the second region to gain AVA status, and today, there are around 270 AVAs across the United States with California boasting the greatest number (more than 100), followed by other major producers like Oregon, Washington, New York, and Virginia.

AVAs delineate and define the distinct terroirs that shape the profile of American wines. Here are some of the country's most prestigious and influential wine regions:

• Napa Valley, California - World-famous for Cabernet Sauvignon, power, and prestige
• Willamette Valley, Oregon - Elegant Pinot Noir, Chardonnay, and cool-climate finesse
• Structured reds, vibrant whites, and broad diversity
• Finger Lakes, New York - Benchmark Riesling with bright acidity and minerality
• Paso Robles, California - Bold Rhône varieties, Cabernet Sauvignon, and innovation

While Napa Valley and Willamette Valley tend to dominate wine headlines, several lesser-known American wine regions are quietly and steadily gaining acclaim for their unique terroirs and innovative winemaking. These include:

• Texas Hill Country, Texas – Tempranillo, Rhône varieties, and rapid growth
• Snake River Valley, Idaho – High-altitude vineyards and lively Riesling
• Lake Chelan, Washington – Mountain-grown wines with vibrancy and balance
• Leelanau & Old Mission Peninsulas, Michigan – Cool-climate Riesling, Pinot Noir, and sparkling wine
• Santa Cruz Mountains, California – Terroir-driven Pinot Noir, Chardonnay, and Cabernet Sauvignon
• Verde Valley, Arizona – Desert viticulture suitable for Mediterranean varieties
• North Fork of Long Island, New York – Maritime-influenced Merlot, Cabernet Franc, and effervescent wine
• Virginia – Rising region known for Cabernet Franc, Viognier, and distinctive terroir

Together, these regions illustrate the evolving landscape of American wine, with new terroirs, grape varieties, and winemaking approaches expanding the country's wine industry.

The AVA system has been hugely significant for defining American wine geography and driving higher quality, but, like all appellation systems, it isn’t without challenges.

Firstly, some AVAs regions are vast, covering diverse climates and soils, while others are tiny and tightly defined. This inconsistency in size can make the meaning of an AVA label vary widely depending on its designation.

Next, numerous AVAs are located within larger AVAs, and some even overlap in complex ways. This can be challenging for consumers trying to make sense of quality hierarchy.

Additionally, unlike many European appellation systems, AVAs don’t dictate strict rules about fruit yields, permitted varieties, or winemaking methods. As such, an AVA designation on a label indicates origin, but not necessarily style or quality. It is, however, worth noting that this vineyard and winemaking freedom can be a strength for an AVA, allowing vintners to approach wine production in a responsive, creative manner for finest quality. The bottom line is, the result can be variable.

Another challenge is, beyond big-name regions like some of those listed above, consumers don’t have deep awareness of many AVAs. This means the usefulness of the designation as a marketing tool can be limited for wineries.

Finally, the increasing number of AVAs could put the significance of the hierarchy at risk, increasing fragmentation rather than clarification.

All this being said, the AVA system, while not perfect, has boosted the ‘recognition’ and ‘identity’ factors of numerous American wine regions, making them immediately synonymous with specific grapes, styles, and quality. These defining qualities have supported the promotion and enjoyment of wines in the US and beyond.

American wines didn’t stop at The Judgment of Paris. Reds, whites, stills, and sparklings regularly win major international awards and are some of the most decorated wines in international competitions like the Decanter World Wine Awards, the International Wine Challenge, and the San Francisco International Wine Competition.

Not bad for a country that, only a generation ago, was barely on the world wine map!

So, as you celebrate the 250th birthday of the United States, why not reflect on July 4 wine history, and sip one of your favorite AVAs?

Happy July 4th!

Old World vs New World wine: What are the main appellation differences?

European appellations (such as France’s AOCs or Italy’s DOCGs) typically regulate grape varieties, yields, and winemaking methods. Under TTB wine regulations, American AVAs, by contrast, define only geographic origin, giving winemakers far greater freedom in grape choice and production style.

How long does it take to become an AVA?

Becoming an American Viticultural Area (AVA) typically takes around one to three years, though complex petitions can take longer. The process involves submitting a detailed application to the TTB, including evidence of unique geographic or climatic features, defined boundaries, and a proposed name. The proposal is then reviewed, opened for public comment, and may be revised before final approval.

What’s a recent AVA?

One of the most recently established AVAs is the Verde Valley AVA, which was officially approved in 2021.

What is one of the largest AVAs in the U.S.?

The Columbia Valley AVA, spanning much of eastern Washington and parts of Oregon, is one of the largest, covering a vast and diverse wine-growing landscape of 18,000 square miles.

What is one of the smallest AVAs in the U.S.?

One of the smallest is the Cole Ranch AVA in California, a tiny, highly specific site in Mendocino County, measuring less than a quarter of a square mile.
