Syrah

Syrah is a dark-skinned variety of grape used in wine. Syrah is grown in many countries and is primarily used to produce powerful red wines, which enjoy great popularity in the marketplace, relatively often under the synonym Shiraz. Syrah is used both for varietal wines and in blended wines, where it can be both the major and minor component. It is called Syrah in its country of origin, France, as well as in the rest of Europe, Argentina, Chile, and most of the United States. The name Shiraz became popular for this grape variety in Australia, where it has long been established as the most grown dark-skinned variety. In Australia it was also commonly called Hermitage up to the late 1980s, but since that name is also a French Protected designation of origin, this naming practice caused a problem in some export markets and was dropped. The name Shiraz for this grape variety is also commonly used in South Africa, Canada, and New Zealand. DNA profiling in 1999 found Syrah to be the offspring of two obscure grape varieties from southeastern France, Dureza and Mondeuse Blanche.

As of 2004, Syrah was estimated to be the world's 7th most grown variety at 142,600 hectares (352,000 acres), after having enjoyed a strong growth in plantings for several years.

The grape is also known under many other synonyms that are used in various parts of the world including Antourenein Noir, Balsamina, Candive, Entournerein, Hignin Noir, Marsanne Noir, Schiras, Sirac, Syra, Syrac, Serine, and Sereine.

Syrah should not be confused with Petite Sirah, a synonym for Durif, another grape variety which is a cross of Syrah with Peloursin dating from 1880.

Origin

Syrah has a long documented history in the Rhône region of Southeastern France, but before 1998 it was not known with certainty if it had originated in that region or was brought there. In that year, a study conducted by Carole Meredith's research group in the Department of Viticulture and Enology at University of California, Davis used DNA typing and extensive grape reference material from the viticultural research station in Montpellier, France to conclude that Syrah was the offspring of the grape varieties Dureza (father) and Mondeuse Blanche (mother).[3][4][5][6][7] Dureza is a dark-skinned grape variety from the Ardèche region in France that have all but disappeared from the vineyards, and the preservation of such varieties is a speciality of Montpellier. Mondeuse Blanche is a white grape variety cultivated in the Savoy region, and still found in very small amounts in that region's vineyards today. Both varieties are somewhat obscure today, have never achieved anything near Syrah's fame or popularity, and there is no record of them ever having been cultivated any long distance from their present home. Thus, both Syrah's parents come from a limited area in southeastern France, very close to northern Rhône, where Syrah came to fame. Based on these findings, the researchers have concluded that Syrah originated in the same place where it came to fame - northern Rhône.

The DNA typing leaves no room for doubt in this matter, and the numerous other hypotheses of the grape's origin which have been forwarded during the years all completely lack support in form of documentary evidence or ampelographic investigations, be it by methods of classical botany or DNA. Instead, they seem to have been based primarily or solely on the name or synonyms of the variety. Because of varying orthography for grape names, especially for old varieties, this is in general very thin evidence. Despite this, origins such as Syracuse or the Iranian city of Shiraz have been proposed.

The parentage information does however not reveal how old the grape variety is, i.e., when the pollination of a Mondeuse Blanche vine by Dureza took place, leading to the original Syrah seed plant. In the year AD 77, Pliny the Elder wrote in his Naturalis Historia about the wines of Vienne (which today would be called Côte-Rôtie), where the Allobroges made famous and prized wine from a dark-skinned grape variety that had not existed some 50 years earlier, in Virgil's age. Pliny called the vines of this wine Allobrogica, and it has been speculated that it could be today's Syrah. However, the description of the wine would also fit, for example, Dureza and Pliny's observation that the vines of Allobrogica was resistant to cold is not entirely consistent with Syrah.
The name Shiraz and associated legends
It seems that many of the legends of Syrah's origins come from one of its many synonyms - Shiraz. Since there also is a city in Persia/Iran called Shiraz, where the famous Shirazi wine was produced, some legends have claimed that the Syrah grape originated in Shiraz, and was brought to Rhône, which would make Syrah a local French synonym and Shiraz the proper name of the variety.

There are at least two significantly different versions of the myth, giving different accounts of how the variety is supposed to have been brought from Shiraz to Rhône and differing up to 1,800 years in dating this event. In one version, the Phocaeans should have brought Syrah/Shiraz to their colony around Marseilles (then known as Massilia), which was founded around 600 BC. The grape should then later have made its way to northern Rhône, which was never colonized by the Phocaeans. No documentary evidence exists to back up this legend, and it also requires that the variety later has vanished from the Marseilles region without leaving any trace.

In another version, the person who brought the variety to Rhône is even named, being the crusader Gaspard de Stérimberg, who is supposed to have built the chapel at Hermitage. Even before the advent of DNA typing of grapes, there were several problems with this legend. First, no ampelographic investigations of the grapes from Shiraz seem to have been made. Second, it is documented that Shirazi wine was white, ruling out the use of dark-skinned grapes such as Syrah, and no known descriptions of this wine's taste and character indicate any similarity whatsoever with red wines from the Rhône. Third, it is highly doubtful if any crusader would have journeyed as far east as Persia, since the crusades were focused on the Holy Land.
The legend connecting Syrah with Shiraz in Iran may however be of French origin, since it is supposed to have been included in a 1826 book called Œnologie Française, although that book used the name Scyras for the grape variety.

Since the name Shiraz has been used primarily in Australia in modern time, while the earliest Australian documents use the spelling "Scyras", it has been speculated (among others by Jancis Robinson) that the name Shiraz is in fact a so-called "strinization" of Syrah's name via Scyras. However, while the names Shiraz and Hermitage gradually seem to have replaced Scyras in Australia from the mid-19th century, the spelling Shiraz has also been documented in British sources back to at least the 1830s. So, while the name or spelling Shiraz may be an effect of the English language on a French name, there is no evidence that it actually originated in Australia, although it was definitely the Australian usage and the Australian wines that made the use of this name popular.

Other legends

Another legend of the grape variety's origin, based on the name Syrah, is that it was brought from Syracuse by the legions of Roman Emperor Probus sometime after AD 280. This legend also lacks documentary evidence and is inconsistent with ampelographic findings.

Rise to fame

The wines that made Syrah famous were those from Hermitage, the hill above the town Tain-l'Hermitage in northern Rhône where there is an hermitage (chapel) on the top, and where de Stérimberg is supposed to have settled as an hermit after his crusades. Hermitage wines have for centuries had a reputation for being powerful and excellent. While Hermitage was quite famous in the 18th and 19th centuries, and attracted interest from foreign oenophiles such as Bordeaux enthusiast Thomas Jefferson, it lost ground and foreign attention in the first half of the 20th century.

In the 18th and the first half of the 19th centuries, most Hermitage wine that left France did so as a blending component in Bordeaux wines. In an era when "clarets" were less powerful than today, and before appellation rules, red wines from warmer regions would be used for improvement (or adulteration, depending on the point of view) of Bordeaux wines. While Spanish and Algerian wines are also known to have been used for this purpose, top Bordeaux châteaux would use Hermitage to improve their wines, especially in weaker vintages.

Arrival in Australia

In 1831, the Scotsman James Busby, often called "the Father of Australian viticulture", made a trip back to Europe to collect cuttings from vines (primarily from France and Spain) for introduction to Australia. One of the varieties collected by him was Syrah, although Busby used the two spellings "Scyras" and "Ciras". The cuttings were planted in the Sydney Botanical Gardens, and in Hunter Valley, and in 1839 brought from Sydney to South Australia. By the 1860s, Syrah was established as an important variety in Australia.

Modern history

Syrah continues to be the main grape of the Northern Rhône and is associated with classic wines such as Hermitage, Cornas and Côte-Rôtie. In the Southern Rhône it is used as a blending grape in such wines as Châteauneuf-du-Pape, Gigondas and Côtes du Rhône, where Grenache usually makes up the bulk of the blend. Although its best incarnations will age for decades, less-extracted styles may be enjoyed young for their lively red and blueberry characters and smooth tannin structure. Syrah has been widely used as a blending grape in the red wines of many countries due to its fleshy fruit mid-palate, balancing the weaknesses of other varieties and resulting in a "complete" wine.´

From the 1970s and even more from the 1990s, Syrah has enjoyed increased popularity, and plantings of the variety has expanded significantly in both old and new locations. In the early 2000s, it broke into the top 10 of varieties planted worldwide for the first time.

Cabernet Sauvignon

Cabernet Sauvignon is one of the world's most widely recognized red wine grape varieties. It is grown in nearly every major wine producing country among a diverse spectrum of climates from Canada's Okanagan Valley to Lebanon's Beqaa Valley. Cabernet Sauvignon became internationally recognized through its prominence in Bordeaux wines where it is often blended with Merlot and Cabernet franc. From France, the grape spread across Europe and to the New World where it found new homes in places like California's Napa Valley, Australia's Coonawarra region and Chile's Maipo Valley. For most of the 20th century, it was the world's most widely planted premium red wine grape until it was surpassed by Merlot in the 1990s.

Despite its prominence in the industry, the grape is a relatively new variety, the product of a chance crossing between Cabernet franc and Sauvignon blanc during the 17th century in southwestern France. Its popularity is often attributed to its ease of cultivation - the grapes have thick skins and the vines are hardy and resistant to rot and frost - and to its consistent presentation of structure and flavours which express the typical character ("typicity") of the variety. Familiarity and ease of pronunciation have helped to sell Cabernet Sauvignon wines to consumers, even when from unfamiliar wine regions. Its widespread popularity has also contributed to criticism of the grape as a "colonizer" that takes over wine regions at the expense of native grape varieties.

For many years, the origin of Cabernet Sauvignon was not clearly understood and many myths and conjunctures surrounded it. The word "Sauvignon" is believed to be derived from the French sauvage meaning "wild" and to refer to the grape being a wild Vitis vinifera vine native to France. Until recently the grape was rumoured to have ancient origins, perhaps even being the Biturica grape used to make ancient Roman wine and referenced by Pliny the Elder. This belief was widely held in the 18th century, when the grape was also known as Petite Vidure or Bidure, apparently a corruption of Biturica. There was also belief that Vidure was a reference to the hard wood (French vigne dure) of the vine, with a possible relationship to Carménère which was once known as Grand Vidure. Other theories were that the grapevine originated in the Rioja region of Spain.[3]

While the period when the name Cabernet Sauvignon became more prevalent over Petite Vidure is not certain, records indicate that the grape was a popular Bordeaux planting in the 18th century Médoc region. The first estates known to have actively grown the variety (and the likely source of Cabernet vines for other estates) were Château Mouton and Château d'Armailhac in the Pauillac.

The grape's true origins were discovered in the late 1990s with the use of DNA typing at the UC Davis Department of Viticulture and Enology, by a team lead by Dr. Carole Meredith. The DNA evidence determined that Cabernet Sauvignon was the offspring of Cabernet franc and Sauvignon blanc and was most likely a chance crossing that occurred in the 17th century. Prior to this discovery, this origin had been suspected from the similarity of the grapes' names and the fact that Cabernet Sauvignon shares similar aromas with both grapes--such as the black currant and pencil box aromas of Cabernet franc and the grassiness of Sauvignon blanc.

While Cabernet Sauvignon can grow in a variety of climates, its suitability as a varietal wine or as a blend component is strongly influenced by the warmth of the climate. The vine is one of the last major grape varieties to bud and ripen (typically 1-2 weeks after Merlot and Cabernet franc) and the climate of the growing season affects how early the grapes will be harvested. Many wine regions in California give the vine an abundance of sunshine with few problems in ripening fully, which increases the likelihood of producing varietal Cabernet wines. In regions like Bordeaux, under the threat of incremental harvest season weather, Cabernet Sauvignon is often harvested a little earlier than ideal and is then blended with other grapes to fill in the gaps. As global warming has increased the number of warm vintage years, the possibility of creating varietal Cabernet in Bordeaux has also increased, making the decision to blend based more on ideology and tradition. In some regions, climate will be more important than soil. In regions that are too cool, there is a potential for more herbaceous and green bell pepper flavours from less than ideally ripened grapes. In regions where the grape is exposed to excess warmth and over-ripening, there is a propensity for the wine to develop flavours of cooked or stewed blackcurrants.

The Cabernet grape variety has thrived in a variety of vineyard soil types, making the consideration of soil less of concern particularly for New World winemakers. In Bordeaux, the soil aspect of terroir was historically an important consideration in determining which of the major Bordeaux grape varieties where planted. While Merlot seemed to thrive in clay and limestone based soils (such as those of the Right Bank regions of the Gironde estuary), Cabernet Sauvignon seemed to perform better in the gravel based soil of the Médoc region on the Left Bank. The gravel soils offered the benefit of being well drained while absorbing and radiating heat to the vines, aiding ripening. Clay and limestone based soils are often cooler, allowing less heat to reach the vines, delaying ripening. In regions where the climate is warmer, there is more emphasis on soil that is less fertile, which promotes less vigor in the vine which can keep yields low. In the Napa Valley wine regions of Oakville and Rutherford, the soil is more alluvial and dusty. Rutherford Cabernet Sauvignon has been often quoted as giving a sense of terroir with a taste of "Rutherford dust". In the South Australian wine region of Coonawarra, Cabernet Sauvignon has produced vastly different results from grapes vines planted in the region's terra rosa soil-so much so that the red soil is considered the "boundary" of the wine region, with some controversy from wine growers with Cabernet Sauvignon planted on red soil.

In addition to ripeness levels, the harvest yields can also have a strong influence in the resulting quality and flavors of Cabernet Sauvignon wine. The vine itself is prone to vigorous yields, particularly when planted on the vigorous SO4 rootstock. Excessive yields can result in less concentrated and flavorful wine with flavors more on the green or herbaceous side. In the 1970s, a particular clone of Cabernet Sauvignon that was engineered to be virus free was noted for its very high yields-causing many quality conscious producers to replant their vineyards in the late 20th century with different clonal varieties. To reduce yields, producers can plant the vines on less vigorous rootstock and also practice green harvesting with aggressive pruning of grape clusters soon after veraison.

In general, Cabernet Sauvignon has good resistance to most grape diseases, powdery mildew being the most noted exception. It is, however, susceptible to the vine diseases Eutypella scoparia and excoriose.

The "green bell pepper" flavor

There are a couple of noted Cabernet Sauvignon flavors that are intimately tied to viticultural and climate influences. The most widely recognized is the herbaceous or green bell pepper flavor caused by pyrazines, which are more prevalent in under-ripened grapes. Pyrazine compounds are present in all Cabernet Sauvignon grapes and are gradually destroyed by sunlight as the grape continues to ripen. To the human palate this compound is detectable in wines with pyrazine levels as low as 2 nanograms (ng) per liter. At the time of veraison, when the grapes first start to fully ripen, there is the equivalent pyrazine level of 30 ng/l. In cooler climates, it is difficult to get Cabernet Sauvignon grapes to ripen fully to the point where pyrazine is not detected. The green bell flavor is not considered a wine fault but it may not be desirable to all consumers' tastes. The California wine region of Monterey was noted in the late 20th century for its very vegetal Cabernet Sauvignon with pronounced green pepper flavor, earning the nickname of "Monterey veggies". In addition to its cool climate, Monterey is also prone to being very windy, which can have the effect of shutting down the grape vines and further inhibiting ripeness.

Two other well known Cabernet Sauvignon flavors are mint and eucalyptus. Mint flavors are often associated with wine regions that are warm enough to have low pyrazine levels but are still generally cool, such as Australia's Coonawarra region and some areas of Washington State. There is some belief that soil could also be a contributor to the minty notes, since the flavor also appears in some wines from the Pauillac region but not from similar climate of Margaux. Resinous Eucalyptus flavors tend to appear in regions that are habitats for the eucalyptus tree, such as California's Napa and Sonoma valleys and parts of Australia, but there has been no evidence to conclusively prove a direct link between proximity of eucalyptus trees and the presence of that flavor in the wine.

Pinot Noir

Pinot noir (IPA: ['pi.no nw.ar]) is a red wine grape variety of the species Vitis vinifera. The name may also refer to wines produced predominantly from Pinot noir grapes. The name is derived from the french words for "pine" and "black" alluding to the varietals' tightly clustered dark purple pine cone-shaped bunches of fruit.

Pinot noir grapes are grown around the world, mostly in the cooler regions, but the grape is chiefly associated with the Burgundy region of France. It is widely considered to produce some of the finest wines in the world, but is a difficult variety to cultivate and transform into wine.

Pinot noir thrives in France's Burgundy region, particularly on the Côte-d'Or which has produced some of the world's most celebrated wines for centuries. It is also planted in Austria, Argentina, Australia, Canada, Chile, the Republic of Georgia, Germany, Hungary, the Republic of Macedonia, Moldova, New Zealand, South Africa and Switzerland. The United States has increasingly become a major Pinot noir producer, with some of the best regarded coming from the Willamette Valley in Oregon; California's Sonoma County with its Russian River Valley and Sonoma Coast appellations, as well as the Central Coast's Santa Lucia Highlands appellation and the Sta. Rita Hills American Viticultural Area in Santa Barbara County. In New Zealand, it is grown in Martinborough, Waipara, and Central Otago.

The leaves of Pinot noir are generally smaller than those of Cabernet Sauvignon, but larger than those of Syrah. The grape cluster is small and cylindrical, vaguely shaped like a pine cone. Some viticultural historians believe this shape may have given rise to the name. Pinot noir tends to produce narrow trunks and branches. In the vineyard it is sensitive to light exposure, cropping levels (it must be low yielding), soil types and pruning techniques. In the winery it is sensitive to fermentation methods, yeast strains and is highly reflective of its terroir with different regions producing very different wines. Its thin skin makes it highly susceptible to bunch rot and other fungal diseases. The vines themselves are prone to downy mildew, leaf roll, and fanleaf. These complications have given the grape the reputation of being difficult to grow: Jancis Robinson calls Pinot a "minx of a vine" and André Tchelistcheff declared that "God made Cabernet Sauvignon whereas the devil made Pinot noir."

However, Pinot wines are among the most popular in the world. Joel Fleischman of Vanity Fair describes Pinot noir as "the most romantic of wines, with so voluptuous a perfume, so sweet an edge, and so powerful a punch that, like falling in love, they make the blood run hot and the soul wax embarrassingly poetic." Master Sommelier Madeline Triffon calls pinot "sex in a glass". Peter Richardsson of OenoStyle christened it "a seductive yet fickle mistress!"

The tremendously broad range of bouquets, flavors, textures and impressions that Pinot noir can produce sometimes confuses tasters. In the broadest terms, the wine tends to be of light to medium body with an aroma reminiscent of black cherry, raspberry or currant. Traditional red Burgundy is famous for its fleshy, 'farmyard' aromas, but changing fashions and new easier-to-grow clones have favoured a lighter, fruitier style. The grape's color when young, often compared to that of garnet, is often much lighter than that of other red wines. However, an emerging style from California and New Zealand highlights a more powerful, fruit forward and darker wine that can approach syrah in depth.

It is also used in the production of Champagne (usually along with Chardonnay and Pinot meunier) and is planted in most of the world's wine growing regions for use in both still and sparkling wines. Pinot noir grown for dry table wines is generally low-yielding and often difficult to grow well. Pinot noir grown for use in sparkling wines (e.g. Champagne) is generally higher yielding.

In addition to being used for the production of sparkling and still red wine, Pinot noir is also sometimes used for rosé still wines, and even vin gris white wines.

Riesling


Riesling is a white grape variety which originates in the Rhine region of Germany. Riesling is an aromatic grape variety displaying flowery, almost perfumed, aromas as well as high acidity. It is used to make dry, semi-sweet, sweet and sparkling white wines. Riesling wines are usually varietally pure and are seldom oaked. As of 2004, Riesling was estimated to be the world's 20th most grown variety at 48,700 hectares (120,000 acres) (with an increasing trend), but in terms of importance for quality wines, it is usually included in the "top three" white wine varieties together with Chardonnay and Sauvignon Blanc. Riesling is a variety which is highly "terroir-expressive", meaning that the character of Riesling wines is clearly influenced by the wine's place of origin.

In 2006, Riesling was the most grown variety in Germany with 20.8% and 21,197 hectares (52,380 acres), and in the French region of Alsace with 21.9% and 3,350 hectares (8,300 acres). There are also significant plantings of Riesling in Austria, northern Italy, Australia, New Zealand, United States, Canada, China and Ukraine. In the countries where it is cultivated, Riesling is most commonly grown in colder regions and locations.

Riesling has a long history, and there are several written references to the variety dating from the 15th century, although with varying orthography. The earliest of these references dates from March 13, 1435, when the storage inventory of the high noble Count John IV. of Katzenelnbogen in Rüsselsheim (a small principality on the Rhine, close to today's Rheingau) lists "22 ß umb seczreben Rießlingen in die wingarten" ("22 shillings for Riesling vine cuttings for the vineyard"). The spelling Rießlingen is repeated in many other documents of the time. The modern spelling Riesling was first documented in 1552 when it was mentioned in Hieronymus Bock's Latin herbal.

A map of Kintzheim in Alsace from 1348 contains the text zu dem Russelinge, but it is not certain that this reference is to the grape variety. However, in 1477, Riesling was documented in Alsace under the spelling Rissling. In Wachau in Austria, there is a small stream and a small vineyard both called Ritzling, which are claimed locally to have given Riesling its name. However, there seem to be no documentary evidence to back this up, so this claim is not widely believed to be correct.

Riesling wines are often consumed when young, when they make a fruity and aromatic wine which may have aromas of green or other apples, grapefruit, peach, honey, rose blossom or cut green grass, and usually a crisp taste due to the high acidity. However, Riesling's naturally high acidity and range of flavours make it suitable for extended aging. International wine expert Michael Broadbent rates aged German Rieslings, some hundreds of years old, extremely highly. Sweet Riesling wines, such as German Trockenbeerenauslese are especially suited for cellaring since the high sugar content provides for additional preservation. However, high quality dry or off-dry Riesling wine is also known to have not just survived but also been enjoyable at an age exceeding 100 years.

The townhall of Bremen, Germany, stores various German wines, including Riesling based wines, in barrel back to the 1653 vintage.

More common aging periods for Riesling wines would be 5-15 years for dry, 10-20 years for semi-sweet and 10-30+ for sweet versions.
