Grapes

"White" table grapes

A grape is a fruiting berry of the deciduous woody vines of the botanical genus described as Vitis. Grapes can be eaten raw or they can be used for making jam, juice, jelly, wine, grape seed extracts, raisins, vinegar, and grape seed oil. Grapes are a non-climacteric type of fruit, generally occurring in clusters.

History[link]

The cultivation of the domesticated grape began 6,000–8,000 years ago in the Near East.^[1] Yeast, one of the earliest domesticated microorganisms, occurs naturally on the skins of grapes, leading to the innovation of alcoholic drinks such as wine. First traces of red wine are seen in ancient Armenia where apparently, to date, the oldest winery was found, dating to around 4,000 BCE. By the 9th century CE the city of Shiraz was known to produce some of the finest wines in the Middle East. Thus it has been proposed that Syrah red wine is named after Shiraz, a city in Persia where the grape was used to make Shirazi wine. Ancient Egyptian hieroglyphics record the cultivation of purple grapes, and history attests to the ancient Greeks, Phoenicians and Romans growing purple grapes for both eating and wine production. The growing of grapes would later spread to other regions in Europe, as well as North Africa, and eventually in North America.

Native grapes belonging to various species of the Vitis genus proliferated in the wild across North America, and were a part of the diet of many Native Americans, but were considered by European colonists to be unsuitable for wine, who imported vitis vinifera varieties for that purpose.

Description[link]

Grapes are a type of fruit that grow in clusters of 15 to 300, and can be crimson, black, dark blue, yellow, green, orange, and pink. "White" grapes are actually green in color, and are evolutionarily derived from the purple grape. Mutations in two regulatory genes of white grapes turn off production of anthocyanins which are responsible for the color of purple grapes.^[2] Anthocyanins and other pigment chemicals of the larger family of polyphenols in purple grapes are responsible for the varying shades of purple in red wines.^[3][4] Grapes are typically an ellipsoid shape resembling a prolate spheroid.

Grapevines[link]

Most grapes come from cultivars of Vitis vinifera, the European grapevine native to the Mediterranean and Central Asia. Minor amounts of fruit and wine come from American and Asian species such as:

• Vitis labrusca, the North American table and grape juice grapevines (including the concord cultivar), sometimes used for wine, are native to the Eastern United States and Canada.
• Vitis riparia, a wild vine of North America, is sometimes used for winemaking and for jam. It is native to the entire Eastern U.S. and north to Quebec.
• Vitis rotundifolia, the muscadines, used for jams and wine, are native to the Southeastern United States from Delaware to the Gulf of Mexico.
• Vitis amurensis is the most important Asian species.

Juice[link]

Grape juice is obtained from crushing and blending grapes into a liquid. The juice is often sold in stores or fermented and made into wine, brandy, or vinegar. In the wine industry, grape juice that contains 7–23 percent of pulp, skins, stems and seeds is often referred to as "must". In North America, the most common grape juice is purple and made from Concord grapes while white grape juice is commonly made from Niagara grapes, both of which are varieties of native American grapes, a different species from European wine grapes. In California, Sultana (known there as Thompson Seedless) grapes are sometimes diverted from the raisin or table market to produce white juice.^[5]

Distribution and production[link]

According to the Food and Agriculture Organization (FAO), 75,866 square kilometres of the world are dedicated to grapes. Approximately 71% of world grape production is used for wine, 27% as fresh fruit, and 2% as dried fruit. A portion of grape production goes to producing grape juice to be reconstituted for fruits canned "with no added sugar" and "100% natural". The area dedicated to vineyards is increasing by about 2% per year.

The following table of top wine-producers shows the corresponding areas dedicated to grapes for wine making:

World production of grape and some of the important producers

There are no reliable statistics that break down grape production by variety. It is believed that the most widely planted variety is Sultana, also known as Thompson Seedless, with at least 3,600 km². (880,000 acres) dedicated to it. The second most common variety is Airén. Other popular varieties include Cabernet Sauvignon, Sauvignon blanc, Cabernet Franc, Merlot, Grenache, Tempranillo, Riesling and Chardonnay.^[6]

Table and wine grapes[link]

Wine grapes on the vine

Commercially cultivated grapes can usually be classified as either table or wine grapes, based on their intended method of consumption: eaten raw (table grapes) or used to make wine (wine grapes). While almost all of them belong to the same species, Vitis vinifera, table and wine grapes have significant differences, brought about through selective breeding. Table grape cultivars tend to have large, seedless fruit (see below) with relatively thin skin. Wine grapes are smaller, usually seeded, and have relatively thick skins (a desirable characteristic in winemaking, since much of the aroma in wine comes from the skin). Wine grapes also tend to be very sweet: they are harvested at the time when their juice is approximately 24% sugar by weight. By comparison, commercially produced "100% grape juice", made from table grapes is usually around 15% sugar by weight.^[7]

Seedless grapes[link]

Although grape seeds contain many nutrients, some consumers choose seedless grapes; seedless cultivars now make up the overwhelming majority of table grape plantings. Because grapevines are vegetatively propagated by cuttings, the lack of seeds does not present a problem for reproduction. It is an issue for breeders, who must either use a seeded variety as the female parent or rescue embryos early in development using tissue culture techniques.

There are several sources of the seedlessness trait, and essentially all commercial cultivators get it from one of three sources: Thompson Seedless, Russian Seedless, and Black Monukka, all being cultivars of Vitis vinifera. There are currently more than a dozen varieties of seedless grapes. Several, such as Einset Seedless, Benjamin Gunnels's Prime seedless grapes, Reliance and Venus, have been specifically cultivated for hardiness and quality in the relatively cold climates of northeastern United States and southern Ontario.^[8]

An offset to the improved eating quality of seedlessness is the loss of potential health benefits provided by the enriched phytochemical content of grape seeds (see Health claims, below).^[9][10]

Raisins, currants and sultanas[link]

Raisins

In most of Europe, dried grapes are referred to as "raisins" or the local equivalent. In the UK, three different varieties are recognized, forcing the EU to use the term "Dried vine fruit" in official documents.

A raisin is any dried grape. While raisin is a French loanword, the word in French refers to the fresh fruit; grappe (from which the English grape is derived) refers to the bunch (as in une grappe de raisins).

A currant is a dried Zante Black Corinth grape, the name being a corruption of the French raisin de Corinthe (Corinth grape). Currant has also come to refer to the blackcurrant and redcurrant, two berries unrelated to grapes.

A sultana was originally a raisin made from Sultana grapes of Turkish origin (known as Thompson Seedless in the United States), but the word is now applied to raisins made from either white grapes, or red grapes which are bleached to resemble the traditional sultana.

Health claims[link]

French Paradox[link]

Comparing diets among Western countries, researchers have discovered that although the French tend to eat higher levels of animal fat, the incidence of heart disease remains low in France. This phenomenon has been termed the French Paradox, and is thought to occur from protective benefits of regularly consuming red wine. Apart from potential benefits of alcohol itself, including reduced platelet aggregation and vasodilation,^[11] polyphenols (e.g., resveratrol) mainly in the grape skin provide other suspected health benefits, such as:^[12]

• Alteration of molecular mechanisms in blood vessels, reducing susceptibility to vascular damage
• Decreased activity of angiotensin, a systemic hormone causing blood vessel constriction that would elevate blood pressure
• Increased production of the vasodilator hormone, nitric oxide (endothelium-derived relaxing factor)

Although adoption of wine consumption is not recommended by some health authorities,^[13] a significant volume of research indicates moderate consumption, such as one glass of red wine a day for women and two for men, may confer health benefits.^[14][15][16] Emerging evidence is that wine polyphenols like resveratrol^[17] provide physiological benefit whereas alcohol itself may have protective effects on the cardiovascular system.^[18]

Resveratrol[link]

Grape phytochemicals such as resveratrol (a polyphenol antioxidant), have been positively linked to inhibiting any cancer, heart disease, degenerative nerve disease, viral infections and mechanisms of Alzheimer's disease.^[19][20]

Protection of the genome through antioxidant actions may be a general function of resveratrol.^[21] In laboratory studies, resveratrol bears a significant transcriptional overlap with the beneficial effects of calorie restriction in heart, skeletal muscle and brain. Both dietary interventions inhibit gene expression associated with heart and skeletal muscle aging, and prevent age-related heart failure.^[22]

Resveratrol is the subject of several human clinical trials,^[23] among which the most advanced is a one year dietary regimen in a Phase III study of elderly patients with Alzheimer's disease.^[24]

Synthesized by many plants, resveratrol apparently serves antifungal and other defensive properties. Dietary resveratrol has been shown to modulate the metabolism of lipids and to inhibit oxidation of low-density lipoproteins and aggregation of platelets.^[25]

Resveratrol is found in wide amounts among grape varieties, primarily in their skins and seeds which, in muscadine grapes, have about one hundred times higher concentration than pulp.^[26] Fresh grape skin contains about 50 to 100 micrograms of resveratrol per gram.^[27]

Anthocyanins and other phenolics[link]

Grape cross-section

Anthocyanins tend to be the main polyphenolics in purple grapes whereas flavan-3-ols (i.e. catechins) are the more abundant phenolic in white varieties.^[28] Total phenolic content, a laboratory index of antioxidant strength, is higher in purple varieties due almost entirely to anthocyanin density in purple grape skin compared to absence of anthocyanins in white grape skin.^[28] It is these anthocyanins that are attracting the efforts of scientists to define their properties for human health.^[29] Phenolic content of grape skin varies with cultivar, soil composition, climate, geographic origin, and cultivation practices or exposure to diseases, such as fungal infections.

Red wine may offer health benefits more so than white because potentially beneficial compounds are present in grape skin, and only red wine is fermented with skins. The amount of fermentation time a wine spends in contact with grape skins is an important determinant of its resveratrol content.^[30] Ordinary non-muscadine red wine contains between 0.2 and 5.8 mg/L,^[31] depending on the grape variety, because it is fermented with the skins, allowing the wine to absorb the resveratrol. By contrast, a white wine contains lower phenolic contents because it is fermented after removal of skins.

Wines produced from muscadine grapes may contain more than 40 mg/L, an exceptional phenolic content.^[26][32] In muscadine skins, ellagic acid, myricetin, quercetin, kaempferol, and trans-resveratrol are major phenolics.^[33] Contrary to previous results, ellagic acid and not resveratrol is the major phenolic in muscadine grapes.

The flavonols syringetin, syringetin 3-O-galactoside, laricitrin and laricitrin 3-O-galactoside are also found in purple grape but absent in white grape.^[34]

Seed constituents[link]

Since the 1980s, biochemical and medical studies have demonstrated significant antioxidant properties of grape seed oligomeric proanthocyanidins.^[35] Together with tannins, polyphenols and polyunsaturated fatty acids, these seed constituents display inhibitory activities against several experimental disease models, including cancer, heart failure and other disorders of oxidative stress.^[36][37]

Grape seed oil from crushed seeds is used in cosmeceuticals and skincare products for many perceived health benefits. Grape seed oil is notable for its high contents of tocopherols (vitamin E), phytosterols, and polyunsaturated fatty acids such as linoleic acid, oleic acid and alpha-linolenic acid.^[38][39][40]

Concord grape juice[link]

Commercial juice products from Concord grapes have been applied in medical research studies, showing potential benefits against the onset stage of cancer,^[41] platelet aggregation and other risk factors of atherosclerosis,^[42] loss of physical performance and mental acuity during aging^[43] and hypertension in humans.^[44]

Grape toxicity in dogs[link]

Grapes can cause renal failure in dogs. See the main article on grape and raisin toxicity in dogs.

Religious significance[link]

In the Bible, grapes are first mentioned when Noah grows them on his farm (Genesis 9:20–21). Instructions concerning wine are given in the book of Proverbs and in the book of Isaiah, such as in Proverbs 20:1 and Isaiah 5:20–25. Deuteronomy 18:3–5,14:22-27,16:13-15 tell of the use of wine during Jewish feasts. Grapes were also significant to both the Greeks and Romans, and their God of agriculture, Dionysus, was linked to grapes and wine, being frequently portrayed with grape leaves on his head.^[45] Grapes are especially significant for Christians, who since the Early Church have used wine in their celebration of the Eucharist.^[46] Views on the significance of the wine vary between denominations. In Christian art, grapes often represent the blood of Christ, such as the grape leaves in Caravaggio’s John the Baptist.

Use in religion[link]

Grape juice, because of its non-alcoholic content, is commonly used by those Christians who oppose the partaking of alcoholic beverages, as the "cup" or "wine" in the Lord's Supper.^[47]

The Catholic Church uses wine in the celebration of the Eucharist because it is part of the tradition passed down through the ages starting with Jesus Christ at the Last Supper, where Catholics believe the consecrated bread and wine literally become the body and blood of Jesus Christ, a dogma known as transsubstantiation.^[48] Wine is used (not grape juice) both due to its strong Scriptural roots, and also to follow the Tradition set by the early Christian Church.^[49] The Code of Canon Law of the Catholic Church (1983), Canon 924 says that the wine used must be natural, made from grapes of the vine, and not corrupt.^[50] In some circumstances, a priest may obtain special permission to use grape juice for the consecration, however this is extremely rare and typically requires sufficient impetus to warrant such a dispensation, such as personal health of the priest.

Although alcohol is permitted in Judaism, grape juice is sometimes used as an alternative for kiddush on Shabbat and Jewish holidays and it has the same blessing as wine. Many authorities maintain that grape juice must be capable of turning into wine naturally in order to be used for kiddush. Common practice, however, is to use any kosher grape juice for kiddush.

Information accurate as of 28 February 2012.

Michael Matusow (born April 30, 1968 in Los Angeles, California) is an American professional poker player, residing in Henderson, Nevada. Matusow's nickname of "The Mouth" reflects his reputation for trash-talking at the poker table. He is also known for sometimes ruining hours or days of good play with a single spectacular misjudgment, (known as a "Mike Matusow Blow-up" or "Mike Matusow Meltdown").^[1][2][3]

Matusow began playing poker seriously in the early 1990s, first while working as a poker dealer, then as a professional player.^[4] His successes include being a three-time World Series of Poker bracelet winner,^[5][6][7] and the winner of the 2005 World Series of Poker Tournament of Champions.^[8]

Early years[link]

Matusow's first experience of poker was playing video poker in the Maxim Casino at the age of 18, which he played regularly, to the extent that he suffered from repetitive strain injury in his shoulders and arms. He occasionally stole money from his mother's purse and at one point attended Gamblers Anonymous meetings. Matusow was taught Texas hold 'em in 1989 by a rounder named Steve Samaroff.^[9]

World Series of Poker[link]

At the 1998 World Series of Poker (WSOP), Matusow paid part of Scotty Nguyen's entrance fee into a satellite event for the $10,000 no limit Texas hold 'em main event. Nguyen went on to win, and gave $333,333 to Matusow in return for his partial stake.^[9][10] In 1999, Matusow won his first WSOP bracelet, winning the $3,500 No Limit Hold'em event defeating Alex Brenes heads-up to win the title.

In 2001, he finished 6th place in the WSOP $10,000 no limit Hold 'em main event. Matusow says that the decisive hand was when he was bluffed by eventual champion Juan Carlos Mortensen, but did not trust his instincts to call.^[9][11]

At the 2002 WSOP, Matusow won his second bracelet by winning the $5,000 Omaha Hi-Low Split 8 or Better event. He defeated his friend and fellow professional poker player Daniel Negreanu to win the tournament.

In the 2005 WSOP, Matusow finished 9th out of 5,619 players in the main event, winning $1,000,000.^[12] Several months later, he won the WSOP Tournament of Champions in a heads-up battle against Hoyt Corkins, earning another $1,000,000 in the process, making him the first player to win two million dollar prizes in the same year. He also placed third in the Tournament of Champions the following year, winning $250,000.^[8][13]

At the 2008 WSOP, Matusow won a third bracelet in the $5000 No Limit 2–7 Draw with rebuys event defeating Jeff Lisandro heads up for the $537,862 first prize.^[7] Later in the same year he finished 30th out of 6,844 players in the Main Event, making yet another deep run in the Main Event.

World Series of Poker Bracelets[link]

Other poker events[link]

In October 2004, Matusow made his first World Poker Tour (WPT) final table at the UltimateBet Aruba Classic, earning $250,000 for 3rd place.^[14] In 2006, he finished runner-up to Tony G in the WPT Bad Boys of Poker II in heads-up play.^[15] Matusow also appeared in Poker Superstars III, where he made it to the Elite Eight. In the winner-take-all championship match, Matusow beat seven other players to win $500,000. He also appeared in the second, third, fourth and sixth season of High Stakes Poker.^[16][17] In September 2006, Mike made his debut on the European Poker Tour (EPT) in Barcelona; however, he was eliminated on the first day. In early 2007, Matusow appeared on two episodes of Poker After Dark where he finished 3rd and 2nd respectively. He plays online poker under the following aliases: "dill pickle" (UltimateBet); "mrpokejoke" (PokerStars); and "Mike Matusow" (Full Tilt Poker, where he is also a member of "Team Full Tilt").^[1][4]

In July 2007, Matusow won $671,320 after coming in second place at the World Poker Tour Bellagio Cup III Championship after online pro Kevin Saul defeated him during heads-up play.^[18] On November 11, 2008 at the World Poker Tour Foxwoods World Poker Finals, Matusow made another WPT final table, He was eliminated after his A♠ J♥ didn't improve against Jonathan Little's hand of 9♥ 9♠, he finished in 6th place, earning $124,048.

As of 2010, his total live tournament winnings exceed $7,400,000.^[19] $3,140,713 of his winnings have come at the WSOP.^[20]

Personal life[link]

Matusow is both loved and disliked by many poker fans. At the 2007 WSOP Main Event final table, Tournament Director Jack Effel asked the audience to recognize one of Effel's "favorite" players. The fans cheered and booed.^[21] Matusow has had several personal problems. He has battled drug issues, including a six-month stint in jail in 2004 and 2005 after being caught providing ecstasy and prescription painkillers to an undercover police officer who pretended to befriend Matusow and gained his trust. After several months of an official Las Vegas Metro Police "Sting Operation", Matusow was arrested and charged with 6 category A Felonies, all drug related. ^[22] A Plea deal was later reached where Matusow was incarcerated in The Clark County Dentention Center for 6 months. ^[23][24]

He has also dealt with being overweight, detailed on ESPN's broadcast of the 2007 WSOP. During that tournament, Mike made a $100,000 bet with Ted Forrest that he could get down to 181 pounds by June 3, 2008. Mike won the bet on June 3, weighing in at 179 pounds.^[25] Matusow resides in a 3,700-square-foot (340 m²) home in Henderson (with a cathedral ceiling) and bought a $90,000 BMW 645 CI cabriolet from a $750,000 winning session at online poker.^[9] He often wears a gold chain with the Hebrew symbol 'chai' around his neck.^[9] Additionally, Matusow hosted Card Player's poker radio show/podcast, the Circuit, before being replaced by Gavin Smith and Joe Sebok.^[26] He was also the host of Card Player's now defunct online video segment, "The Mouthpiece." In one particular episode, Mike discussed the controversial Ultimatebet.com superuser cheating scandal, as well seeking legal action as a victim of the scandal against the main perpetrator, former World Series of Poker Champion Russ Hamilton.^[27]

In 2009 Mike Matusow signed a contract with Deepstacks.com to become the Dean of Deepstacks University, an interactive poker training site.

Matusow wrote an autobiography entitled Check Raising the Devil that was released May 12, 2009.^[28]

Matusow currently does a Poker online Live show entitled, "Mike The Mouth Live" at scottmatusow.com/radio Each Thursday at 3 P.M Pacific Time
