How We Got to Know About Wine

/0 Comments/in , , , /by

Archaeological evidence has established the earliest-known production of wine from fermenting grapes during the late Neolithic or early Chalcolithic in the Caucasus and the northern edge of the Middle East. An extensive gene-mapping project in 2006 analyzed the heritage of more than 110 modern grape cultivars, narrowing their origin to a region of Georgia. This matches the earliest discovered sites containing shards of wine-stained pottery, dated to c. 6000 BC in Georgia, and c. 5000 BC in Iran. The jars at the northwestern Iranian site already showed treatment with preservative turpentine pine resin, the flavoring of modern retsina. By c. 4500 BC, wine production had spread to Grecian Macedonia, the site of the first recovered crushed grapes, and an entire winery was discovered in 2011 inside the Areni-1 cave in Armenia, dated to c. 4100 BC. A 2003 report by archaeologists indicates a possibility that grapes were mixed with rice to produce mixed fermented beverages in China in the early years of the seventh millennium BC. Pottery jars from the Neolithic site of Jiahu, Henan, contained traces of tartaric acid and other organic compounds commonly found in wine. However, other fruits indigenous to the region, such as hawthorn, cannot be ruled out. If these beverages, which seem to be the precursors of rice wine, included grapes rather than other fruits, they would have been any of the several dozen indigenous wild species in China, rather than Vitis vinifera, which was introduced there some 6,000 years later.

The spread of wine culture westwards was most probably due to the Phoenicians who spread outward from a base of city-states along the Lebanese and Palestinian coast. The wines of Byblos were exported to Egypt during the Old Kingdom and then throughout the Mediterranean. Evidence includes two Phoenician shipwrecks from 750 BC discovered by Robert Ballard, whose cargo of wine was still intact. As the first great traders in wine (cherem), the Phoenicians seem to have protected it from oxidation with a layer of olive oil, followed by a seal of pinewood and resin, again similar to retsina.

Literary references to wine are abundant in Homer (8th century BC, but possibly relating earlier compositions), Alkman (7th century BC), and others. In ancient Egypt, six of 36 wine amphoras were found in the tomb of King Tutankhamun bearing the name “Kha’y”, a royal chief vintner. Five of these amphoras were designated as originating from the king’s personal estate, with the sixth from the estate of the royal house of Aten. Traces of wine have also been found in central Asian Xinjiang in modern-day China, dating from the second and first millennia BC.

This discovery narrowed down the search to the central Dalmatian coastal strip and its offshore islands. Eventually a matching DNA fingerprint was found among the samples. The match came from a vine sampled in 2001 in the vineyard of Ivica Radunić in Kaštel Novi. This Crljenak Kaštelanski (“Kaštela Red”) appears to represent Primitivo/Zinfandel in its original home, although some genetic divergence may have occurred since their separation. Meredith now refers to the variety as “ZPC” – Zinfandel / Primitivo / Crljenak Kaštelanski.
This Croatian vineyard contained just nine Crljenak Kaštelanski vines mixed with thousands of other vines. In 2002, additional vines known locally as Pribidrag were found in the Dalmatian coastal town of Omiš. Both clones are being propagated in California under the aegis of Ridge Vineyards, although virus infections have delayed their release.

The first Croatian ZPC wine was made by Edi Maletić in 2005. Meanwhile, plantings of Primitivo have increased in California, where it seems to grow somewhat less vigorously than its sibling. Its wines are reputed to have more blackberry and spice flavors.

In the 2012 book Wine Grapes Masters of wine Jancis Robinson and Julia Harding and Swiss grape geneticist Dr. José Vouillamoz detail the search for Zinfandel’s origins. After years of research and DNA testing of vines from vineyards across the globe, a single 90-year-old grape vine from the garden of an elderly lady in Split, Croatia, provided the evidence to show that Zinfandel was a Croatian grape that has been known as Tribidrag since at least the 15th century.

Classification Of Wine

/0 Comments/in , , , , /by

Regulations govern the classification and sale of wine in many regions of the world. European wines tend to be classified by region (e.g. Bordeaux, Rioja and Chianti), while non-European wines are most often classified by grape (e.g. Pinot noir and Merlot). Market recognition of particular regions has recently been leading to their increased prominence on non-European wine labels. Examples of recognized non-European locales include Napa Valley, Santa Clara Valley and Sonoma Valley in California; Willamette Valley in Oregon; Columbia Valley in Washington; Barossa Valley in South Australia and Hunter Valley in New South Wales; Luján de Cuyo in Argentina; Central Valley in Chile; Vale dos Vinhedos in Brazil; Hawke’s Bay and Marlborough in New Zealand; and Okanagan Valley and Niagara Peninsula in Canada. Some blended wine names are marketing terms whose use is governed by trademark law rather than by specific wine laws. For example, Meritage (sounds like “heritage”) is generally a Bordeaux-style blend of Cabernet Sauvignon and Merlot, but may also include Cabernet Franc, Petit Verdot, and Malbec.

France has various appellation systems based on the concept of terroir, with classifications ranging from Vin de Table (“table wine”) at the bottom, through Vin de Pays and Appellation d’Origine Vin Délimité de Qualité Supérieure (AOVDQS), up to Appellation d’Origine Contrôlée (AOC) or similar, depending on the region.

Commercial use of the term Meritage is allowed only via licensing agreements with the Meritage Association.

Portugal has developed a system resembling that of France and, in fact, pioneered this concept in 1756 with a royal charter creating the Demarcated Douro Region and regulating the production and trade of wine. Germany created a similar scheme in 2002, although it has not yet achieved the authority of the other countries’ classification systems. Spain, Greece and Italy have classifications based on a dual system of region of origin and product quality.

Popularity and Backlash of Chardonnay

/0 Comments/in , , , , /by

Due to the “malleability” of Chardonnay in winemaking and its ability to reflect its terroir, there is not one distinct universal “style” or set of constants that could be applied to Chardonnay made across the globe. According to Jancis Robinson, a sense of “smokiness” is one clue that could be picked up in a blind tasting of Chardonnay but there are many styles that do not have any “smokey” notes. Compared to other white wine grapes like Sauvignon blanc, Gewürztraminer and Viognier-Chardonnay has a more subtle and muted nose with no overwhelming aromatics that jump out of the wine glass. The identifying styles of Chardonnay are regionally based. For example, pineapple notes are more commonly associated with Chardonnay from Napa Valley while Chablis will have more notes of green apples. While many examples of Chardonnay can benefit from a few years of bottle aging, especially if they have high acidity, most Chardonnays are meant to be consumed in their youth. A notable exception to this is the most premium examples of Chablis and white Burgundies.

Chardonnay long had a reputation as one of France’s great white wines, but due to the dominance of geographical labeling, the fact that Chardonnay was the grape behind white Burgundy was not widely known by the wine-drinking public. The success of California and new world Chardonnays, partly encouraged by the Californian showing at the Judgment of Paris wine tasting, brought varietal wine labeling to more prominence and the easy to pronounce Chardonnay grape was one of the largest beneficiaries. In the late 1980s, a sort of “Chardonnay-mania” developed as wine regions (particularly new and developing ones) dramatically increased their planting of the grape to meet the world wide demand. Chardonnay became very fashionable in the 1990s, as the stereotypical drink of young urban women of the Bridget Jones generation.

But as more vineyards responded with massive new plantings of the variety, they found that fashions were changing again. The market was drinking more red wine, and there was a backlash against heavy, oaky, New World Chardonnays in favor of lighter wines such as Pinot grigio. There was a new fashion, “ABC” – Anything But Chardonnay, identified by Frank Prial in 1995. Another reason for the backlash was that Chardonnay was seen as a symbol of the globalization of wine, in which local grape varieties were grubbed up in favor of the big names demanded by international markets. Oz Clarke described a view of Chardonnay as “…the ruthless coloniser and destroyer of the world’s vineyards and the world’s palates.” The criticism was centered on the habits of winemakers to pull out or give up on local varieties in order to plant more Chardonnay which offered potentially more income but lack the uniqueness and character of local varieties. Examples of this occurred in south Italy and Spain when ancient Negroamaro, Primitivo, Grenache and Mataro vineyards were ripped up in favor of new Chardonnay plantings. Despite the backlash, Chardonnay remains very popular. In 2004 Chardonnay was estimated to be the world’s 6th most widely grown grape variety, covering 179,300 hectares (443,000 acres).

In the United States, for a wine to be vintage-dated and labeled with a country of origin or American Viticultural Area (AVA) (e.g. Sonoma Valley), 95% of its volume must be from grapes harvested in that year. If a wine is not labeled with a country of origin or AVA the percentage requirement is lowered to 85%. Vintage wines are generally bottled in a single batch so that each bottle will have a similar taste. Climate’s impact on the character of a wine can be significant enough to cause different vintages from the same vineyard to vary dramatically in flavor and quality. Thus, vintage wines are produced to be individually characteristic of the particular vintage and to serve as the flagship wines of the producer. Superior vintages from reputable producers and regions will often command much higher prices than their average ones. Some vintage wines (e.g. Brunello), are only made in better-than-average years. For consistency, non-vintage wines can be blended from more than one vintage, which helps winemakers sustain a reliable market image and maintain sales even in bad years. One recent study suggests that for the average wine drinker, the vintage year may not be as significant for perceived quality as had been thought, although wine connoisseurs continue to place great importance on it.

The Power of Bordeaux

/0 Comments/in /by

A Bordeaux wine is any wine produced in the Bordeaux region of France, centred on the city of Bordeaux and covering the whole area of the Gironde department, with a total vineyard area of over 120,000 hectares, making it the largest wine growing area in France. Average vintages produce over 700 million bottles of Bordeaux wine, ranging from large quantities of everyday table wine, to some of the most expensive and prestigious wines in the world. Eighty-nine percent of wine produced in Bordeaux is red (called “claret” in Britain), with sweet white wines (most notably Sauternes), dry whites, and also (in much smaller quantities) rosé and sparkling wines (Crémant de Bordeaux) collectively making up the remainder. Bordeaux wine is made by more than 8,500 producers or châteaux. There are 54 appellations of Bordeaux wine.

The vine was introduced to the Bordeaux region by the Romans, probably in the mid-1st century, to provide wine for local consumption, and wine production has been continuous in the region since then.

In the 12th century, the popularity of Bordeaux wines in England increased dramatically following the marriage of Henry Plantagenet and Eleanor of Aquitaine. The marriage made the province of Aquitaine part of the Angevin Empire, and thenceforth the wine of Bordeaux was exported to England. At this time, Graves was the principal wine region of Bordeaux, and the principal style was clairet. This accounts for the ubiquity of claret in England. The export of Bordeaux was interrupted by the outbreak of the Hundred Years’ War between France and England in 1337. By the end of the conflict in 1453 France had repossessed the province, thus taking control of wine production in the region.

In the seventeenth century, Dutch traders drained the swampy ground of the Médoc in order that it could be planted with vines, and this gradually surpassed Graves as the most prestigious region of Bordeaux. Malbec was dominant grape here, until the early 19th century, when it was replaced by Cabernet Sauvignon.

In 1855, the châteaux of Bordeaux were classified; this classification remains widely used today. From 1875–1892 almost all Bordeaux vineyards were ruined by Phylloxera infestations. The region’s wine industry was rescued by grafting native vines on to pest-resistant American rootstock. Red Bordeaux is generally made from a blend of grapes. Permitted grapes are Cabernet Sauvignon, Cabernet Franc, Merlot, Petit Verdot, Malbec and rarely Carménère. Today Carménère is rarely used, with Château Clerc Milon, a fifth growth Bordeaux, being one of the few to still retain Carménère vines.

Truth In a Bottle

[trx_dropcaps style=”1″]Whether the wine is aging in tanks or barrels, tests are run periodically in a laboratory to check the status of the wine. Common tests include °Brix, pH, titratable acidity, residual sugar, free or available sulfur, total sulfur, volatile acidity and percent alcohol. Additional tests include those for the crystallization of cream of tartar (potassium hydrogen tartrate) and the precipitation of heat unstable protein; this last test is limited to white wines. These tests may be performed throughout the making of the wine as well as prior to bottling. In response to the results of these tests, a winemaker can decide on appropriate remedial action, for example the addition of more sulfur dioxide. Sensory tests will also be performed and again in response to these a winemaker may take remedial action such as the addition of a protein to soften the taste of the wine.[/trx_dropcaps]

Brix is one measure of the soluble solids in the grape juice and represents not only the sugars but also includes many other soluble substances such as salts, acids and tannins, sometimes called Total Soluble Solids (TSS).

Because sugar is the dominant compound in grape juice, these units are effectively a measure of sugar level. The level of sugar in the grapes determines the final alcohol content of the wine as well as indirect index of grape maturity. Brix (Bx for short) is measured in grams per hundred grams of solution, so 20 Bx means that 100 grams of juice contains 20gm of dissolved compounds. There are other common measures of sugar content of grapes, Specific gravity, Oechsle (Germany) and Beaume (France). In the French Baumé (Be° or Bé° for short) one Be° corresponds approximately to one percent alcohol. One Be° is equal to 1.8 Brix, that is 1.8 grams of sugar per one hundred grams. Therefore, to achieve one percent alcohol the winemaker adds 1.8 grams per 100 ml or 18 grams per liter — a practice known as chaptalization, which is illegal in some countries and in California. Brix is usually measured with a refractometer while the other methods use a hydrometer. Generally, hydrometers are a cheaper alternative.

Volatile acidity test verifies if there is any steam distillable acids in the wine. Mainly present is acetic acid (the dominant component of vinegar), but lactic, butyric, propionic, and formic acid can also be found. Usually the test checks for these acids in a cash still, but there are other methods available such as HPLC, gas chromatography and enzymatic methods. The amount of volatile acidity found in sound grapes is negligible, because it is a by-product of microbial metabolism. Because acetic acid bacteria require oxygen to grow, eliminating any air in wine containers as well as addition of sulfur dioxide will limit their growth. Rejecting moldy grapes also prevents possible problems associated with acetic acid bacteria. Use of sulfur dioxide and inoculation with a low-V.A. producing strain of Saccharomyces may deter acetic acid producing yeast. A relatively new method for removal of volatile acidity from a wine is reverse osmosis. Blending may also help—a wine with high V.A. can be filtered (to remove the microbe responsible) and blended with a low V.A. wine, so that the acetic acid level is below the sensory threshold.

The Importance of Terroir

/0 Comments/in /by

The influence of terroir means that wines from a particular region are unique, incapable of being reproduced outside that area, even if the grape variety and winemaking techniques are painstakingly duplicated. Winemakers in Burgundy do not believe that they are producing Pinot noir that happens to be grown in Burgundy, but that they are producing unique Burgundian wines that happen to be made from Pinot noir. Appellation systems, such as the French AOC systems, have developed around the concepts of “unique wines from a unique area”. These systems have also developed into protected designation of origin across the European Union so that, for example, winemakers from outside a region like Tuscany can not produce a Sangiovese wine and call it a Chianti. While the wine may be made from the same clonal variety of Sangiovese, in the same soil composition as found in the Chianti region with winemakers using the Tuscan method of production, there is an assumption that the two wines will be different due to terroir.

The names of these European wine regions are protected so that wines from different regions and different terroir are not confused with wines from that those regions – i.e. A Spanish or Australian “chianti”.

In the United States there is some confusion over the use of semi-generic names like Champagne and Port but there has been more effort by the American wine industry to recognize the unique association of place names with the wines produced in those places, such as the 2005 Napa Declaration on Place agreement. While appellation systems and the protected designations of origin can be a way of protecting “unique terroir”, the commercial importance of terroir has been a much debated topic in the wine industry.

The importance of terroir affects the price of the agricultural product as well as the products made from the product. Branding, variety, and farmer identification affects the price of a product. The Slow Food movement appreciates history of a variety of plant or animal, the story of the farmer who produced it, and ultimately the quality of the product. Chefs and bakers develop their own list of qualities they desire for their creations, and terroir affects these. Wine critics question the value of a Pinot noir wine from a Burgundy Grand Cru vineyard relative to a wine produced from the “lesser terroir” of a Premier Cru vineyard, and whether it merits the higher price. These doubts also arise when the quality of winemaking and other human influences are taken into account, which may be of a higher standard with the “lesser” premier cru.

[trx_quote author=”Benjamin Franklin”]Wine is constant proof that God loves us and loves to see us happy.[/trx_quote]

These critics also question the difference between New World and Old World wine and whether modern winemaking techniques – like significant oak influences, over-ripened fruit, cultured yeast, micro-oxygenation, and color pigment additives – obscure or even eliminate the influence of terroir in making different regions unique. Critics often point to the homogenizing effect on mass-produced wines made from popular varietals like Chardonnay, which may have their terroir characteristics hidden by invasive and intensive winemaking. A heavily-oaked, over-ripe Chardonnay from California can taste very similar to the same style of wine from elsewhere. The marketability of wines from different regions and producers is affected by the importance accorded to terroir, both by the wine industry and consumer wine markets, with some producers downplaying terroir and its effect on their wines.
