Malbec is a brilliant wine to serve at a barbecue, or match the food to the location of the wine — for example try a Cahors Malbec with a a classic French cassoulet.

In France it is grown in the Northern Rhône and blended with Roussanne to make long-lived and expensive white wines.

Most Marsanne produces dry, still white wines and when young will have lemon and stone fruit flavours, whilst ageing mellows these to draw out a prominent honeysuckle style. Young Australian Marsanne is great with our easy fish recipes as well as strong-tasting vegetables like asparagus.

But there's more to it than you might think: it is planted across the world, and in Bordeaux where it originates it goes into some of the world's finest wines.

Most Merlots are designed to be drunk young, but the best wines from Bordeaux will last for years. Merlots usually have rich, plummy fruit and chocolate notes, with soft tannins and relatively high alcohol content. In cooler climates, in can be more herbal and similar to Cabernet Sauvignon.

When aged it gets becomes spicy and even more herbal. Merlot-rich wines from Bordeaux go very well with mushroom risotto , especially if you add a splash of the wine when cooking. Find out more with our full guide to Merlot.

Petit Verdot is a grape that's rarely found solo. Instead, it makes a common appearance in blends of Merlot, Cabernet Sauvignon and Cabernet Franc. It thrives in warm climates, making distinctive wines in Australia, California and South Africa to name just a few.

Petit Verdot is high-tannin and when young can be a bit much so it usually spends time in oak, which tames the tannins and brings out a spicy side. This bold flavour means it pairs well with equally strong foods: think barbecued meats or lamb rogan josh.

Find out more with our full guide to Petit Verdot. Pinot Grigio is one of the most popular grapes in Britain. Most Pinot Grigios you'll find here are simple dry wines from northern Italy, ideal for drinking cold on sunny days.

Pinot Grigio is most commonly usually crisp, with citrus fruit, apples and a hint of spice. Italian Pinot Grigio is great with seafood recipes or fresh veg dishes, like a vibrant green pea risotto. Find out more with our full guide to Pinot Grigio. Riesling is a white grape with a strong reputation.

It's a cool climate grape, native to Germany but now grown across the world where it's not too hot — from Austria and Australia to Washington State and the Alsace in France. It is famous for its acidity — present even in the sweetest presentations of Riesling — and the exact flavours vary based on location.

Find out more with our full guide to Riesling. Syrah has soared in popularity since the s and can be found far and wide beyond its native Rhône valley, being particularly strong in Chile, South Africa and Argentina.

It's often known as Shiraz, particularly in Australia where it is the most planted grape. In the northern Rhône, Syrah can be surprisingly light-bodied with floral notes, while in Australia, flavours move towards rich cherry and chocolate. Try it with roast lamb or pair with spices in chickpea curry or North African dishes.

Find out more with our full guide to Syrah. Tempranillo is an Iberian speciality. Tempranillo is a chameleon grape, making everything from fruity light reds to oak-aged wines.

Follow the 'if it grows together, it goes together' rule for food pairing — since it is the dominant red grape in Spain and Portugal, Tempranillo is an excellent match with tapas and cured meats. Why not enjoy it alongside a feast of our delicious tapas such as ham croquetas , patatas bravas meatballs and sautéed chorizo with red wine?

Find out more with our full guide to Tempranillo. Verdejo hails from northern Spain. It was traditionally used to make fortified wines but since the s, has become one of Spain's best white wines, producing crisp and dry whites with pronounced acidity and grassy herbal flavour.

Young, crisp Verdejo tastes best cold, whereas richer examples should be served a little warmer. The high acidity in Verdejo matches well with battered fish, as it cuts through the fat — try our beer-battered fish burgers.

Richer examples are a great substitute for white Burgundy, and go well with buttery dishes and poultry. Find out more with our full guide to Verdejo.

An increasingly popular white, Vermentino is most likely native to northern Italy but is found across the whole country, plus France there are actually more hectares grown here than Italy , Australia and California too.

Vermentino usually tastes of citrus fruit such as lemons, oranges and satsumas. Best examples come from Piedmont and Sardinia and often have a salty, mineral edge. Good examples also age well, giving them body to stand up to to rich tomato dishes like ratatouille and pasta dishes.

The vines found there provide a contrast with the red soil , found on the oldest terraces of Basque estates. Incidentally, the colour of these plots is still a guarantee of the quality of the vines that grow there.

Whether in British Columbia , not far from Okanagan Lake , or in Ontario , near Niagara Falls , certain natural landscapes in Canada come to life at the beginning of winter, during a special harvest, carried out after the first frost. The grapes harvested are used to make what are known as ice wines , notable for their rarity.

To successfully perform this minor miracle, which is very risky in terms of damaging fruit that has been on the vine a long time, the Canadian winegrowers use Vidal Blanc , a hybrid grape variety known for its thick skin and capacity to withstand harsh winter conditions.

This sweet dessert wine will warm the hearts of travellers who have come to discover the fauna and flora of a country usually associated with maple syrup. As wines from around the world are readily available, you can always bring back a bottle or two from your favourite trips, and have a good time with friends by organising tastings focused on one grape variety.

Wines made from the same variety come from a diversity of climates and soil types that never fails to astonish the uninitiated and often wine buffs, too.

It's used as a safety net for producers of Piedmont's Nebbiolo and Barbera wines, which take much longer to age. There are seven DOC's: Acqui, Alba, Asti, Dinao d' Alba, Dogliani, Langhe Monregalesi and Ovada.

Beaujolais makes its famous, fruity reds exclusively from one of the many Gamay clones available. Gamay grapes produce wines low in alcohol and relatively high in acidity, the wines are meant to be drunk soon after bottling; the ultimate example of this is Beaujolais Nouveau, which is whipped onto shelves everywhere almost overnight by the third week in November.

It is also grown in the Loire, but there it makes no remarkable wines. The Swiss grow it widely for blending with Pinot Noir. Gewurztraminer grapes can yield magnificent wines, as is best demonstrated in Alsace, France, where it is made into a variety of styles from dry to off-dry to sweet.

The grape needs a cool, sunny climate to ripen fully. It is a temperamental grape to grow and vinify, as its potent spiciness can be overbearing when unchecked. At its best, is produces a floral and refreshing wine with crisp acidity that pairs well with spicy dishes.

When left for late harvest, it's uncommonly rich and complex, yielding a tremendous dessert wine. Gewurztraminer is also popular in Eastern Europe, New Zealand, and the Pacific Northwest. Drought and heat resistant, Grenache grapes yield a fruity, spicy, medium-bodied wine with supple tannins. The second most widely planted grape in the world, Grenache is widespread in the southern RhôneValley.

It figures strongly in the blend of Chateauneuf-du-Pape although there are some pure varietals , and it is used on its own for the rose wines of Tavel and Lirac; it is also used in France's sweet Banyuls wine. Grenache is also important in Spain , where it's known as Garnacha Tinta; it is especially noteworthy in Rioja and Priorat.

Grenache used to be more popular in Australia, but has now been surpassed by Syrah, although a few Barossa Valley producers are making wines with Grenache similar to Chateauneuf-du-Pape. In California, it's a workhorse-blending grape, although occasionally old vines are found and its grapes are made into a varietal wine, which at its best can be quite good.

It may make a comeback as enthusiasts of Rhône style wines seek cooler areas and an excellent blending grape. Malbec was once important in Bordeaux and the Loire, where it figured into various blends, but it has steadily lost ground in recent years. This 'not very hardy' grape as been steadily replaced by Merlot and the two Cabernets.

However, Argentina is markedly successful with this varietal. In fact, some of that country's finest wines are made exclusively from Malbec.

In the United States, Malbec is used almost exclusively as a blending grape, and an insignificant one at that, but a few wineries use it, the most obvious reason being that it is considered part of the Bordeaux cepage or blend. Marsanne is popular in the Rhône along with Grenache Blanc, Roussane and Viognier and Australia, especially in Victoria, which now has some of the world's oldest Marsanne vineyards.

At its best, Marsanne can be a full-bodied, moderately intense wine with spice, pear and citrus notes. Merlot is the red-wine success of the s: its popularity has soared along with its acreage, and it seems wine lovers can't get enough of it. It dominates Bordeaux, except for the Medoc and Graves.

Although it is mainly used as a supporting player in the Bordeaux blend, it can stand alone. In St. Emilion and Pomerol, especially, it produces noteworthy wines, culminating in Chateau Petrus - Bordeaux's most expensive wine.

In Italy it's everywhere, though most of the Merlot there is light, unremarkable stuff. However, there are strong exceptions to that rule. Despite its popularity, its quality ranges only from good to very good most of the time, though there are a few stellar producers found around the world.

Several styles of Merlot have emerged in California. One is a Cabernet-style Merlot, which includes a high percentage up to 25 percent of Cabernet blended into the Merlot. A second style is less reliant on Cabernet, so it yields a softer, suppler, medium-weight, less tannic wine that features more herb, cherry and chocolate flavors.

A third style is a very light and simple wine; this type's sales are fueling Merlot's overall growth. As long as the weather is warm, Mourvèdre ably tolerates a wide variety of soils. It is popular across the south of France, especially in Provence, where it is responsible for the greatness of Bandol, and many a fine red Cotes-du-Rhône.

It is often blended in Chateauneuf-du-Pape; Languedoc makes it as a varietal. Spain uses it in many areas, including Valencia. In the United States, Mourvèdre remains a minor factor for now, pursued by a few wineries that specialize in Rhône-style wines.

The wine it produces can be quite pleasing, with medium weight, spicy cherry and berry flavors and moderate tannins. It ages well. Muscat is a legacy of the ancient world. Today, it is known primarily as Muscat, Muscat Blanc, or Muscat Canelli. It is marked by strong spice and floral notes, and it can be produced as a varietal or used in blending, its primary function in California.

Moscato in Italy, Moscatel in Iberia, this grape can turn into anything from the low-alcohol, sweet and frothy Moscato d' Asti and Muscat de Canelli to bone-dry wines like Muscat d' Alsace.

Muscat also produces fortified wine such as Beaume de Venise. The great grape of Northern Italy, where it excels in Barolo and Barbaresco, Nebbiolo fashions strong, flavorful, age-worthy wines.

Mainly unsuccessful elsewhere, Nebbiolo is struggling to gain a small foothold in California. So far, the Nebbiolo wines from California have been light and uncomplicated, bearing little resemblance to their Italian cousins.

Petite Sirah has long been favored as a blending grape in France and California, where it offers otherwise simple, light-colored wines greater color, depth, intensity, and tannin. Petite Sirah is actually related to Durif, a minor French varietal, and is not a true Syrah.

As tastes change, Petite Sirah, with its ripe berry flavors and crisp, chewy tannins, has begun to fall out of favor. Moreover, the dense, inky examples of Petite Sirah that show so much promise early in their lives fail more often than not to improve with age, only becoming more tannic and earthy.

Now believed to be related to Pinot Noir and not Chardonnay, Pinot Blanc was once extensively referred to as the poor man's Chardonnay because of the two grapes similar characteristics. Presently, Pinot Blanc is used in Champagne, Burgundy, Alsace, Germany, Italy, and California, where it can make terrific wines.

When well made, Pinot Blanc is intense, concentrated and complex, with ripe pear, spice, citrus, and honey notes. It can age well, but is best early on while its fruit shines through.

Known as Pinot Grigio in Italy, where it is grown extensively in the northeast part of the country, this varietal produces quite a lot of very drinkable dry white wines as well as Collio's excellent whites. As Pinot Gris, it used to be grown in Burgundy and in the Loire Valley, although it has been supplanted there.

However, Pinot Gris comes into its own in Alsace-where it is known as Tokay. Southern Germany plants it as Rulander. When fine, this varietal is soft and gently perfumed. Moreover, it possesses more color and charm than most whites.

Pinot Noir, the great red grape of Burgundy, is a touchy varietal. The best examples offer the classic black cherry, spice, raspberry, and currant flavors, and an aroma that can resemble wilted roses, as well as earth, tar, herb and cola notes.

Conversely, Pinot Noir can also be rather ordinary, light, simple, herbal, vegetal and even weedy. Other times, it can be downright funky, with pungent barnyard aromas.

In fact, Pinot Noir is the most fickle of all grapes to grow: It reacts strongly to environmental changes such as heat and cold spells, and it is notoriously fussy to work with once picked, since its skins are easily bruised and broken.

Even after fermentation, Pinot Noir can hide its weaknesses and strengths, making it a most difficult wine to evaluate out of barrel. In the bottle, too, it is often a chameleon, showing poorly one day, brilliantly the next.

Nevertheless, it can and does produce some of the planet's greatest red wines, like Romanee Conti. Primitivo, referring to the early ripening of this ancient varietal rather than any supposed rusticity, hails originally from Greece. It was most likely brought to southern Italy more than 2, years ago by the Greeks, who named Apulia and the nearby Italian peninsula Enotria - land of the vine - because of its natural proclivity for the production of wine.

Today, Primitivo remains one of the most important varietals in southern Apulia, especially on the Salento peninsula.

In addition to being the earliest maturing grape variety in Europe, and perhaps the world, it is also capable of registering the highest sugar content of any grape, translating into the world's most alcoholic table wine. Recent DNA evidence points to Primitivo as the forebear of California Zinfandel, a grape with which it shares many common characteristics, thereby ending the mystery surrounding the origin of Zinfandel.

Riesling wines can be distinguished by their floral perfume, but after that they vary widely. In Germany's Mosel-Saar-Ruwer area, the wines are delicate and subtle, with very low-alcohol, while in the Pfalz they become spicy, exuberant and full-bodied.

In Alsace, the result is more often than not bone-dry. Because Riesling is one of the grapes susceptible to Botrytis cinerea, it also produces luscious late-harvest dessert wines. In addition to Germany and Alsace, Australia, Austria, and New Zealand also produce some compelling Rieslings.

Sangiovese is best known for providing the backbone for many superb Italian red wines, including Chianti and Brunello di Montalcino, as well as the so-called SuperTuscan blends.

Sangiovese is distinctive for its supple texture and medium-to-full-bodied spice, raspberry, cherry and anise flavors. When blended with a grape such as Cabernet Sauvignon, Sangiovese gives the resulting wine a smoother texture and more supple tannins. Sauvignon Blanc is a white varietal with a notable aroma, which is often characterized as "grassy" or "herbal.

As part of a blend, the grape is all over Bordeaux, in Pessac-Leognan, Graves and the Medoc; it also shows up in Sauternes. New Zealand has had striking success with Sauvignon Blanc in recent years, producing its own perfumed, fruity style that has spread to North America and back to France.

On its own or in a blend, this white varietal can age. With Sauvignon Blanc, its traditional partner and life long friend, Semillon is the foundation of Sauternes and most of the great dry whites found in Graves and Pessac-Leognan; these are rich, honeyed wines.

Semillon is one of the grapes susceptible to Botrytis cinerea. Australia's Hunter Valley uses it solo to make a full-bodied white that used to be known as Hunter Riesling, Chablis or White Burgundy.

In South Africa, this grape was once so prevalent that it was just called "wine grape," but production there has declined drastically in recent years. Semillon can make a wonderful late-harvest wine, and those wineries that focus on it can make well-balanced wines with complex fig, pear, tobacco and honey notes.

When blended into Sauvignon Blanc, Semillon adds body, flavor and texture. When Sauvignon Blanc is added to Semillon, the latter gains fresh, grassy herbal notes. Hermitage and Cote-Rotie in France, the great old vines renditions of South Australia-the epitome of Syrah is a majestic red that can age for half a century.

The grape seems to grow well in a number of areas and is capable of rendering rich, complex, and distinctive wines, with pronounced pepper, spice, black cherry, tar, leather and roasted nut flavors, as well as a smooth, supple texture and ripe tannins. In the south of France, it finds its way into various blends, as in Chateauneuf-du-Pape and the better wines of the Languedoc-Roussillon.

Known as Shiraz in Australia, Syrah was long used there for bread-and-butter blends, but an increasing number of high-quality varietal bottlings are now being made, especially from old vines in the Barossa Valley. Tempranillo is the ubiquitous Spanish grape varietal that is responsible primarily or in part for nearly every great Spanish red, whether it is from Rioja, Priorat, or Ribera del Duero.

Its greatness is almost always consummate with the skill of the winemaker and the yield per acre. Trebbiano in Italy and Ugni Blanc in France. Regardless of the name, this varietal is tremendously prolific; low in alcohol but high in acidity, it is found in almost any basic white Italian wine.

It is so ingrained in Italian winemaking that it is actually a sanctioned, ingredient of the blend used for red Chianti and Vino Nobile di Montepulciano. However, most current Tuscan producers choose not add it to their wines, any longer. Viognier, the rare white grape of France's Rhône Valley, is one if the most difficult grapes to grow.

Nevertheless, fans of this floral, spicy white wine are thrilled by its prospects in the south of France and in the New World, most especially in California and Chile. The origins of this tremendously versatile and popular grape are still not known for certain, although it is thought to have come from Southern Italy as a cousin of Primitivo.

Zinfandel is the most widely planted red grape in California although Australia has also played around with the grape. Much of it is vinified into white Zinfandel, a blush colored, slightly sweet wine.

Real Zinfandel, the red wine, is the quintessential California red. It can also be used for blending with other grapes, including Cabernet Sauvignon and Petite Sirah.

Home Crop production Wine grapes Grape variety identification. English Español. Many grapes for the home garden are American grape varieties, as they are more disease resistant. Some are crosses between American Vitis species and European grape species Vitis vinifera. Therefore, if you suspect that your grapevine is decades old, it may be one of the more traditional cultivars available through garden centers.

If you want help identifying your grapevine, contact your county Extension office for assistance. Specifically inquire with the Master Gardener Help Desk , as they may be able to further assist in cultivar identification based on their experience and other local resources.

However, make sure that you have clear photos that identify the plant parts see Ampelography below. Make sure you have photos of your plant with ripe, disease-free fruit. Having diseased or unhealthy plant tissue makes it difficult for cultivar identification. Commercial growers If you do not have records of the plant material planted in your vineyards, there two ways to determine the cultivar and rootstock.

Ampelography — You can use physical characteristics of the shoot tips, leaves, and fruit to identify the grape cultivar. This is a complicated process, and the details provided in the following guide provide details on this complexity: official grape identification guide.

The Vitis International Variety Catalogue can be used to search cultivars and rootstocks for images of shoot tips, leaves and fruit. Use the database search feature. This is helpful in determining the variety but is not completely definitive.
