If Cabernet Sauvignon is the king of red grapes, Chardonnay is the queen of whites. The variety is California's most widely planted winegrape, with 93,452 acres reported in 2017. Chardonnay far and away remains the most popular wine in the U.S. and has continued to be the leading varietal wine for the last decade, with sales increases every year. Chardonnay represented an estimated 19 percent of table wine volume purchased in U.S. food stores in 2017, according to estimates by The Nielsen Company and Gomberg-Fredrikson & Associates. In 2017, California crushed 614,000 tons of Chardonnay.

Fans of Chardonnay are familiar with the wine's classic descriptors: green apple, fig and citrus flavors, a complex aroma, and high acidity for a crisp wine. The wine is often aged in oak to produce toasty, vanilla and buttery overtones.

The Chardonnay Grape

Genetic studies have identified Chardonnay as a cross between Pinot Noir and Gouais Blanc. Historical references note California plantings of Chardonnay dating back to the late 1800s, but production remained limited because of the grape's low yields. Most Chardonnay vineyards were uprooted during Prohibition when growers replaced them with thick-skinned varieties that could be shipped cross country. Small plantings in the Livermore Valley and Santa Cruz Mountains survived Prohibition. It was not until the 1970s and thereafter that Chardonnay plantings boomed as the wine became increasingly popular.

Of California table wine shipments, Merlot is the third leading red varietal after Cabernet Sauvignon and Red Blends purchased by Americans today. California Merlot consumption held a 7% share of shipments in U.S. food stores in 2016, according to the Nielsen Company and Gomberg, Fredrikson & Associates estimates.

What is the reason for Merlot's popularity? Industry observers offer possible explanations. Consumers continue to try red wine because of news reports linking moderate drinking to a healthy lifestyle. Also, white and blush drinkers may be expanding their preferences to red. Merlot may be the choice in both instances because of the soft, approachable and luscious character that is appealing to new and regular red wine drinkers. In restaurants, Merlot's average price is similar to the average price of the widely popular Chardonnay varietal.

The Merlot Grape

Merlot is one of the principal winegrape varieties of the Bordeaux region in France, and was brought to California in the mid-19th century. Historically, vintners have used Merlot as a blending grape to soften a wine, usually with Cabernet Sauvignon. Merlot tannins are less forceful than Cabernet Sauvignon, so Merlot wine tends to mature earlier. Merlot is now primarily popular as a varietal wine. Most of the Merlot vines are planted in Lodi/San Joaquin County, followed by Napa Valley, Monterey, and Sonoma counties.

Moscato’s popularity has grown in recent years, and comes in styles varied enough to suit every taste. Muscat grapes produce table, sparkling and dessert wines, in shades of white, pink or red, ranging from dry to deliciously sweet. Traditionally, Italian winemakers used the grape to produce low-alcohol, spritzy white wines often poured as an aperitif. While today’s versatile wines pair well with many dishes, sparkling and late-harvest Moscatos are particularly good with fruit tarts or rich cheesecake.

The Muscat Grape

The Muscat grape has been grown around the Mediterranean for many centuries. In fact, Muscat Blanc may be the oldest known winegrape variety. Muscat grapes comes in wine, table and raisin varieties. In addition to Muscat Blanc, which makes the majority of wine in California, other Muscat varieties include Muscat of Alexandria, Orange Muscat, Muscat Gaillo, sometimes called Giallo, Diamond Muscat, and Summer Muscat.

According to Nielsen Company U.S. Supermarket data, 5 percent of the wine sold by volume in U.S. food stores in 2016 was Moscato. The 2016 total crush for all California Muscat grapes came in at 200,602 tons, more than double that of 2011.

Pinot Grigio is a white wine grape that most often yields a soft, low acidic wine that may be slightly aromatic. With its crisp stone fruit and citrus flavors, California Pinot Grigio adds a refreshing verve to most any light meal. The grape itself has a pinkish-grey skin, hence the name gris (French for grey). Pinot Grigio is the Italian synonym for the grape also commonly known as Pinot Gris, a noble variety that has origins in Alsace, France. In America, the synonyms, Pinot Grigio and Pinot Gris, are both fairly prevalent. Pinot Grigio is known to be a deviation of the Pinot Noir grape, and leaves of the two varietals are quite similar. Historically, they have grown side by side in the same vineyard.

The popularity of Pinot Grigio has risen in recent years. The acreage in California was reported at 2,835 in the year 2001 and has increased to 16,718 acres in 2016, becoming the third-leading white variety behind Chardonnay (94,532 acres) and French Colombard (18,961 acres). according to the California Grape Acreage Report.

Pinot Gris/Pinot Grigio acreage is largest in San Joaquin County with 5,040 acres, representing nearly a third of the state’s 16,718 acres. San Joaquin, along with Fresno, Sacramento and Monterey counties, are responsible for more than half of the state’s total. Today Pinot Grigio is spreading into nearly all the state’s major wine growing counties.

When the hit movie "Sideways" was released on October 22, 2004, with the central character Miles extolling the virtues of Pinot Noir, U.S. supermarket sales of the variety jumped 18 percent between October 24, 2004 and July 2, 2005, compared to the same period a year earlier. Pinot Noir, however, had been steadily growing in popularity long before "Sideways" helped propel the wine into mainstream American awareness. In 2016, California crushed 253,995 tons of Pinot Noir, compared to more than 32,000 tons of Pinot Noir crushed in 1990, according to the California Grape Crush Reports. Clearly, Americans are expanding their preference for the fresh raspberry, plum, rose and spice flavors and aromas of Pinot Noir.

The Pinot Noir Grape

Pinot Noir can be complex, elusive and difficult to grow. Yet many winemakers will make Pinot Noir because the resulting wines can reap a reward as great as the challenge. This noble red wine variety is ancient, described by Romans in 100 A.D. and cultivated in the Burgundy region of France as early as the 4th century. Pinot Noir is prone to genetic variation, and has more clones than any other variety. The University of California, Davis, has some 100 registered Pinot Noir clones. The variety does well in the coolest growing areas where it develops excellent color and flavor.

Riesling is an aromatic white grape variety known for its high acidity and flowery aromas that tend to thrive in cooler wine growing regions. It is the main winegrape of Germany but has significant plantings throughout the new and old world wine regions. Riesling is used to make a wide range of wines from dry to sweet and is sometimes used in sparkling wines. The grape is known to greatly express the terroir of where it is grown, but will still maintain the characteristics which identify it. Riesling has been described as flowery, honey-like, and complex, as well as spicy and long lasting or lingering on the palate. Try Riesling with Thai spring rolls, spicy stir-fried chicken, or a bacon, lettuce and tomato sandwich on crusty country bread.

In California, Riesling is also known by its botanical name or synonym White Riesling. The ice wine, late harvest, and botrytized Rieslings are among the most prized and age-worthy wines in the world.

The acreage of Riesling has grown over the last decade in California to 4,009 acres. Monterey County is by far the leader with 1,651 acres.

Pink is charming and pretty — the color of flowers, seashells, clouds at twilight or the soft glitter of fire opals. Pink is also the color of some delicious wines. The wines appear delicate, but many are strong enough to stand up to spicy foods. They are also light enough to be a versatile match with a variety of lighter dishes. These pretty wines are known by several names including rosé, blanc de noir, vin gris or simply blush. The wines may also have a name using the single grape variety from which they may be made, such as White Zinfandel, White Grenache, Pinot Noir Blanc or White Merlot.

White Zinfandel accounts for the majority of blush wine consumed in the U.S. A favorite since the 1970s, these crisp, slightly sweet (generally 2.5% residual sugar) wines have introduced many consumers to the enjoyment of wine. For 52 weeks ending June 17, 2017, pink wines accounted for 9.3% of the volume sold in large volume food stores and other large volume outlets in the U.S., according to Nielsen figures.

The other wines in the pink genre are the bone-dry rosés and blanc de noirs. Gaining accolades and market share, these beautiful dry wines have high acidity, and complex aromas and fruit flavors. From a smaller base, dry rosés gained over 26% volume share of the blush category last year, per Nielsen.

Winemakers use nearly all types of red grapes to produce these wines. For rosés, well-colored grape skins are allowed only brief contact with the clear juice after crushing to produce the light crimson hues of a rosé wine, generally an average of six to 24 hours of skin contact. Blanc de noir wines, a term applied to white wines from black grapes, also known as vin gris-style wines, are also produced by quickly separating the clear juice from the color-laden grape skins, but immediately after crushing so that only the barest blush of pale color remains in the wine. Both rosé and blanc de noir wines are then made like white wines.

Sauvignon Blanc is a noble grape variety that produces some of the world’s most popular wines. In California, the wineries label their products as Sauvignon Blanc or Fumé Blanc. The wines have a range of distinctive tastes from citrus, green olive and herbaceous characteristics to a range of fruit flavors—green apple, grapefruit, pineapple, fig and melon. The flavor styles come from the Sauvignon Blanc grape itself but are also the expression of the climate, soil, vineyard practices and winemaking techniques. Sauvignon Blanc is often blended with other varietal wines, particularly Semillon, which adds a honeyed note to the wine. Generally, the wines are crisp, light, fresh and dry. A versatile food match, it pairs well with chicken, seafood, mildly spiced ethnic dishes and more.

The grape variety was first planted in California in the Livermore Valley in the 19th century. According to the 2016 California Grape Acreage Report, Sauvignon Blanc has almost 15,000 acres in California. It is the fourth-leading white wine variety behind Chardonnay (94,532 acres), French Colombard (18,961 acres), and Pinot Gris (16,718 acres).

Sparkling wine is a beverage that brings to mind several thoughts—celebration, success, luxury, love and romance. These pleasant associations seem to be as strong now as they ever were. And because the wine is offered with different levels of sweetness, menu planners use the wine as an aperitif or a versatile accompaniment to a variety of foods such as salty nuts and cheese, lightly-spiced fish and Asian dishes, fried foods, strawberries and more. California has more than 300 producers and shipped 11 million cases of sparkling wine/champagne to U.S. markets in 2016. Total U.S. and foreign-produced sparkling wine/champagne shipped to the U.S. in 2016 was 25.6 million cases. The category holds a 6.4 percent share of the U.S. wine market.

Several U.S. producers label their sparkling wines “champagne,” and the U.S. government allows the use of the champagne term on U.S. brands established on or before March 2006 as long as the geographic origin accompanies the champagne term on the label. New U.S. brands after this date are not allowed to use the champagne term. Traditional winegrape varieties used in California sparkling wine/champagne production are Chardonnay, Pinot Noir and Pinot Blanc, though many other varieties are used, depending upon the style, production process and price point.

Major Production Processes

Following are the two most common methods used for sparkling wine production:

Méthode champenoise—Still wine is used as a base wine in the process. A blend of base wine, yeast nutrient and a sugar source is added to the base wine. The mixture is sealed, fermented a second time and aged in the bottle, which captures the carbon dioxide released in the fermenting process producing the bubbles.

Charmat process—Still wines are fermented in a pressurized tank. Sugar and yeast are added for a second fermentation, but the wine remains in the tank for this stage of the process and is not fermented in individual bottles.

Styles

Sparkling wine ranges in style from very dry (Natural), dry (Brut), and slightly sweet (Extra Dry) to sweet (Sec and Demi-Sec). (Wines with no noticeable sweetness are described as “dry.”) Many sparkling wines are also identified as “Blanc de Blancs” (wines made from Chardonnay grapes), “Blanc de Noirs” (wines produced from black grapes), or rosé or pink sparkling wine/champagnes (small amount of red wine added to the blend or wine that is allowed brief skin contact with color-laden grape skins).

Syrah is a noble grape variety that can produce some serious, long-lived red wines. The usual aroma and flavor descriptors include blackberry, cassis, black pepper, smoke, as well as dry, dark and tannic.

The Syrah Grape

Through DNA testing, Syrah has shown to be a cross of a black variety, Dureza, and a white variety, Mondeuse, both with origins in France's Rhône region and earlier fabled origins in the Middle East. The grape is also known as Sirah, and in Australia and South Africa, it is called Shiraz. It should not be confused with Petite Sirah, which is altogether a different grape variety, identified more recently as Durif through DNA testing.

Although Syrah acreage has existed in California for some time, such as the pre-Prohibition plantings in Mendocino County, substantial plantings have occurred in the 1990s. Today, as of 2016, the most acreage is in San Luis Obispo County with 2,346 acres, followed by San Joaquin County, 1,852 acres, and Sonoma County, 1,691 acres. Syrah’s grape crush of 108,355 tons in 2016 accounted for 2.6 percent of the total state winegrape crush.

In recent history, Zinfandel was California’s “mystery grape” because its origins were unknown. DNA fingerprinting has confirmed that Italy’s Primitivo and Crljenak Kastelanski, an ancient Croatian variety, are genetically identical to Zinfandel grapes. However, differences in vine vigor and cluster size distinguish Zinfandel from its genetic twins, and further differences in cultivation, terroir and winemaking combine to give California Zinfandel its own particular flavor profile with a truly American name, history and style. On wine labels, U.S. regulations require that Zinfandel and Primitivo be identified separately.

Studies indicate that the grape used for making California Zinfandel probably originated in Croatia. Historians believe that in the 1820s, a nursery owner brought Zinfandel cuttings that were Croatian in origin to the United States from an Austrian collection. The Zinfandel name, however, is truly American—the earliest and only documented use of the name is in America where a Boston nursery owner advertised Zinfandel for sale in 1832.

Zinfandel was introduced to California during the Gold Rush somewhere between 1852 and 1857 and became widely planted because it thrived so well in the state’s climate and soil. Today, Zinfandel is the third-leading winegrape variety in California, with more than 44,400 acres planted and 416,615 tons crushed in 2016, according to the California Department of Food and Agriculture. It is grown in 45 of California’s 58 counties. Although Zinfandel is a red winegrape, the majority of Zinfandel grapes is used to make a rosé (blush) wine called White Zinfandel. Promoted to the world by the state’s vintners for more than 130 years, Zinfandel has grown beyond cult status and is now internationally recognized due to the unique character and high quality wines that are produced only in the Golden State.

Popular descriptors for red Zinfandel include blackberry, raspberry, boysenberry, cherry, as well as black pepper, cloves, anise and herbs.

Advocacy Group: Zinfandel Advocates and Producers (ZAP) is a nonprofit association that organizes seminars, educational programs and wine tastings across the U.S. to promote Zinfandel and its high quality reputation. Their annual Zinfandel Experience in January in San Francisco is the largest single varietal tasting of its kind. ZAP supports research surrounding the history and origins of the Zinfandel grape.
