There is a special dynamic that develops in families with multiple siblings, where one son or daughter excels over the others. It's a common occurrence, across a broad spectrum of life and business.
Same with wine. Certain circumstances cause one wine region to leap ahead of another in popularity. The recognition and rise in popularity of a region or a specific wine might be due to the natural environment, human skill and ingenuity, or both.
A growing environment for wine grapes is complex and is often described by the French term terroir. There are numerous factors such as climate and soil composition that define the terroir of a specific site or region.
Sonoma County and Napa Valley are only a few miles apart in northern California, and both places are known for world class Cabernet Sauvignon, Merlot, Chardonnay and Pinot Noir. But their terroirs are different.
Yet, in the opinion of many wine professionals and consumers, Napa Valley excels in Cabernet Sauvignon and Sonoma is better known for Pinot Noir. There are, of course, exceptions like Cabernet from Sonoma's Alexander Valley and Pinot Noir from Napa Carneros.
So, let's take a closer look at a few general differences, beginning with Cabernet Sauvignon.
Napa Cabernet Sauvignon comes from a collection of relatively small sub-areas such as Oakville, Stags Leap, Atlas Peak, Spring Mountain and Rutherford, with subtle growing differences, like soil variations and climate. The differences range from the cooler south valley near the city of Napa to the warmer northern vineyards around the town of Calistoga.
Sonoma County is more diverse, with the best known Cabernet Sauvignon in the Alexander Valley. Climate and soil variations are felt across a wide spectrum, from warmer Sonoma Valley, to cooler pockets in Green Valley and near the Russian River.
Merlot is a different animal, mainly for its relatively mild softer flavors, compared to the roughness of Cabernet Sauvignon.
The coolest soils in Sonoma County, forming an ideal medium for Merlot, are in Sonoma Valley, Sonoma Mountain and Bennett Valley, with micro-climate pockets throughout the county. Producers such as Matanzas Creek, in Bennett Valley, draw maximum varietal fruit and brisk acidity from the valley soils.
It's a wonder Merlot ripens to plum and dark cherry flavors in the Napa Valley. But the popular varietal does good in cooler south valley vineyards along the Napa River, Napa-Carneros, Wild Horse Valley and Coombsville.
Chardonnay grows best in chalk, limestone and clay soils but it will ripen in a variety of mediums and climates, like the Oakville District, Napa and Sonoma Carneros, Sonoma Coast and the small Chalk Hill and Green Valley sub zones in Russian River Valley.
Terroir is vital for good varietal character in Chardonnay. Diverse areas in Napa and Sonoma can turn out a range of Chardonnay styles, from light and mineral, to warm and tropical. The key is to root vines in soils where they will produce lean, steely/mineral styles or pineapple, mango and honey.
Pinot Noir has been described as the "heartbreak grape," because it's the most ephemeral wine grape, difficult to grow and make. The taste of pinot varies from light and sensual or dark and heavy with a deep almost black color and full black cherry accents.
But reaching for more specifics to describe the taste of Pinot Noir can be a fool's errand because there are many different styles, most of them suggesting descriptors like black cherry, leather and mushrooms. But these are just descriptions and not what Pinot Noir tastes like.
For many fans of California Pinot Noir, Sonoma County's Russian River Valley and Carneros are considered prime sites for Pinot Noir. Other California areas that get high marks for Pinot Noir are Santa Barbara County, Sonoma Coast and Anderson Valley in Mendocino County.
As a broad general statement, Sonoma Coast Pinots are complex and savory and Russian River Pinot Noirs are fuller and darker than Carneros Pinots, with their raspberry and spicy accents. Both Carneros and Russian River are cool climate areas, good for the development of bright acidity.
There are plenty of styles to choose. Find a varietal, then a region a specific producer and decide if your taste is more aligned with Napa Valley or Sonoma County wines.

More on AI & Wine: The hottest topic today in technology is the pros and cons of artificial intelligence. The question for wine consumers: What is the relationship of AI and wine now and in the future and how will it affect wine production and consumption? What follows is only part of the answer.
Various articles recently have reported on the advancements of AI in the vineyard, as well as applying AI to wine sales and marketing. And while those prospects are encouraging, there are a number of observers asking for caution, oversight and control.
Danica Noble, an antitrust attorney with the Washington State Bar Association is calling for more AI oversight, not less. In an article for "The Seattle Times," Noble says the U.S. Senate is considering a law that would "ban states' ability to regulate AI for the next 10 years. "
Georgia Hall, a Bloomberg Opinion Columnist reported a warning from Wall Street firms about the rising risk of using AI for criminal purposes, including software hallucinations.
According to Webster's, a hallucination is "the apparent perception of sights, sounds, etc., that are not actually present." An AI hallucination is false, nonsensical information presented as factual.
With all the talk about shrinking wine sales, the wine industry and wine consumers may now be faced with a spate of possible AI hallucinations related to wine marketing material, wine tasting notes, wine articles and more.
