In a sense, place means everything

Recently, we had a dear friend visit us from Atlanta. A South African native, this was his first trip to Napa and Sonoma. Having spent much of his younger years wandering around Stellenbosch and Constantia in the Western Cape, he was familiar with the concept of wine gardens (what you and I call vineyards). As he drove through the American equivalent, he was blown away by the similarities shared with his homeland.  More than anything, he was surprised by the size of the region. Before his visit, he had assumed that Napa was just one, simple place. One small valley. As in: here’s the town and here are the vineyards. He didn’t expect to find town after town, vineyard after vineyard, and (more tellingly) appellation after appellation. Thrown in between two mountain ranges on either side of the valley (Mayacamas to the west and Vaca to the east), the nuances of the geography and growing regions of the Napa Valley change drastically wherever you go.

Over a bottle of wine, he asked us about the geography and brief history of these various appellations or, as we came to share with him, AVAs. AVA is a term thrown around a lot these days. It stands for American Viticultural Area and accounts for a specific wine-growing region. In a nutshell, it is a legally defined geographic area where grapes are grown. Napa Valley, as a whole, is an AVA, but within the Napa Valley AVA, there are 16 (yes, 16!) sub-appellations. Confused yet? Don’t worry; we’ll help you make sense of this.

As with anything designed to describe specific traits (think Georgia peaches, Vermont Cheddar, or Idaho potatoes) there are rules that protect AVAs. For a wine to qualify under an AVA banner, it has to meet specific requirements set forth by the Alcohol and Tobacco Tax and Trade Bureau. If we were growing a Cabernet in the valley and wanted to label it a Stag’s Leap Cabernet, we would need to ensure that 85% of our juice (grapes) came from the Stag’s Leap AVA.

Some may argue that AVAs are just another way to combat wine fraud by means of designating wine origin. Others may be more contentious and say that it’s a marketing ploy. But for those of us who live here, AVAs make simple, logical sense. In a valley that is over 30 miles long, microclimates exist everywhere you look. And so, by default, the geography of this area truly does create a myriad of authentic and unique growing regions.

For example, the Western slopes of the valley are flanked with dense forestry, while the Eastern hills are more arid and sparsely covered. Up valley, you can get 50-degree temperature swings in a 24-hour period, whereas other parts of the valley have much smaller shifts. Even the dense morning fog (created by the marine layer traveling east off the Pacific Ocean) affects every square foot of the valley a bit differently. Some vineyards are packed with fog well into the late-morning, while other areas see it burn off more quickly. What’s more is that variations in microclimates aren’t the only thing to consider. Add to this the variability of soil composition (volcanic, porous, rocky, etc.), and you have a lot to deal with before the first vine even goes in the ground.

Given all of this, the valley’s climate and soil patterns are fickle and varied at best, frustrating and challenging at worst, and sometimes confound even the most seasoned veterans. Essentially, you can have vineyards just a couple miles apart that produce vastly different grapes. Place, in this sense, means everything. It means that you can have vineyard plots that produce stellar Chardonnay just down the road from plots where Chardonnay would be hard-pressed to grow at all, let alone flourish. Or that two clones of the same Cabernet can be grown on two separate vineyards, just miles from one another, and produce vastly different grapes. Different microclimate, different soil, entirely different ball game.

Taking all of this into account, you can see why producers in different parts of the Valley want their grapes recognized separately of others. Given these distinctions, we figured that before we start traipsing throughout the valley showcasing our interviews and tours, a brief tutorial on the various Napa Valley AVAs was in order.

So, without further adieu, we give you a crash course on the geography of the Napa Valley and its corresponding sub-appellations.

The Towns (from South to North):

Napa

Land of transition and contradictions. A little bit small-town Americana, with a side of rough ‘n tumble, complemented with a topping of budding prosperity.

Yountville

St. Helena

Drive a Range Rover? Then come on down!

But once you’re here, you’ll understand how unique each of these regions are. Just like the people who populate this valley, no two appellations are alike. Similar at times? Yes. But distinct enough to deserve their own merit? Absolutely.
