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.

Jack Vale (September 2, 1973) is an American comedian who has a popular YouTube channel featuring hidden-camera pranks.^[1][2][3][4] He lives in Roseville, California, with his wife and five children.^[5]

Pranks[link]

Several of Vale's pranks are what he calls "Pooter" pranks. These involve Vale walking around in public making flatulence sounds, using a handheld device he created,^[3] and capturing the reactions of the people nearby on a hidden camcorder, which on one occasion resulted in a physical altercation between Vale and an old man whose wife Vale used the device on nearby, despite Vale explaining that it was a prank and even showing him and device. The subsequent police intervention led to both the man and Vale being banned from that specific supermarket.

Other pranks include "Paranoid", a sketch in which Vale, pretending to be talking on his mobile phone, walks past customers in a shop and describes them to his imaginary conversational partner, and "Nonsense", in which Vale confuses members of the public by approaching them and speaking gibberish. Vale is also known to dress up in a mask as an old man while filming his pranks.

Vale has appeared on Lopez Tonight,^[6] performing pranks on various celebrities at the 53rd Grammy Awards,^[7] and performing pranks at a reality television show convention.^[8]

Vale often works with his Uncle, John, who also has his own YouTube channel.

Diana Jean Krall, OC, OBC (born November 16, 1964) is a Canadian jazz pianist and singer, known for her contralto vocals.^[2] She has sold more than 6 million albums in the US and over 15 million worldwide. On December 11, 2009, Billboard magazine named her the second Jazz artist of the 2000–09 decade, establishing her as one of the best-selling artists of her time. She is the only jazz singer to have eight albums debuting at the top of the Billboard Jazz Albums.^[3] To date, she has won three Grammy Awards and eight Juno Awards. She also has earned nine gold, three platinum, and seven multi-platinum albums.

Professional career[link]

In 1993, Krall released her first album, Stepping Out, which she recorded with John Clayton and Jeff Hamilton. It caught the attention of producer Tommy LiPuma, who produced her second album, Only Trust Your Heart (1995).^{[citation needed]}

Her third album, All for You: A Dedication to the Nat King Cole Trio (1996), was nominated for a Grammy and continued for 70 weeks in the Billboard jazz charts. Love Scenes (1997) quickly became a hit record with the trio of Krall, Russell Malone (guitar) and Christian McBride (bass).^{[citation needed]}

In August 2000, Krall was paired on a 20-city tour with Tony Bennett. They were paired again for a song on the TV series Spectacle: Elvis Costello with...^{[citation needed]}

Orchestral arrangements by Johnny Mandel provided the background on When I Look In Your Eyes (1999). The band mix was kept, following arrangements on The Look of Love (2001) created by Claus Ogerman; this record achieved platinum status and reached the top 10 of the Billboard 200. The title track from the album, a cover of the Casino Royale standard popularized in the late 1960s by Dusty Springfield and Sérgio Mendes, reached number 22 on the adult contemporary chart.^{[citation needed]}

In September 2001, Krall began a world tour. Her concert at the Paris Olympia was recorded and released as her first live record, Diana Krall - Live in Paris. The album included covers of Billy Joel's "Just The Way You Are" (a hit on U.S. smooth jazz radio) and Joni Mitchell's "A Case Of You."^{[citation needed]}

The 2001 movie The Score (U.S.A. and Germany) starring Robert De Niro and Marlon Brando, features a recording of Krall entitled: “I’ll Make It Up As I Go.” This song accompanies the film’s ending Credits (Chapter 12) and was composed by a fellow Canadian, David Foster.^[4]

After marrying Elvis Costello, she worked with him as a lyricist and started to compose her own songs, resulting in the album The Girl in the Other Room. The album, released in April 2004, quickly rose to the top five in the United Kingdom and made the Australian top 40 album charts.^{[citation needed]}

She also joined Ray Charles on his Genius Loves Company album in 2004 on the song, "You Don't Know Me".^{[citation needed]}

In late May 2007, Krall was featured in a Lexus ad campaign.^[5] She also sang, "Dream a Little Dream of Me" with piano accompaniment by pianist Hank Jones.

Quiet Nights, her latest album, was released on 31 March 2009.^{[citation needed]}

Krall also produced Barbra Streisand's album Love Is the Answer, released on 29 Sep 2009.^{[citation needed]}

Personal life[link]

Krall was born on November 16, 1964 in Nanaimo, British Columbia, Canada. Her father played piano around the house and her mother sang in a community choir. She was playing piano herself at the age of four and playing jazz in a local restaurant at 15. She went to the Berklee College of Music in Boston on a scholarship before heading out to L.A. to play jazz. She returned to Canada to release her first album in 1993.^[6]

Krall lost her mother Adella to multiple myeloma in 2002, within months of also losing her mentors Ray Brown and Rosemary Clooney.^{[citation needed]} Diana's only sibling, Michelle, is a former member of the Royal Canadian Mounted Police (RCMP).

Krall and British musician Elvis Costello were married on December 6, 2003 at Elton John's estate outside London.^[7] Their twin sons, Dexter Henry Lorcan and Frank Harlan James, were born December 6, 2006 in New York City.^[8]

Honours[link]

In 2000, she was awarded the Order of British Columbia.^[9] In 2003 she was given an honorary Ph.D. (Fine Arts) from the University of Victoria.^[10] In 2004, she was inducted into Canada's Walk of Fame.^[11] In 2005, she was made an Officer of the Order of Canada.^[12]

In 2008, Nanaimo Harbourfront Plaza was renamed Diana Krall Plaza.^[13]

She is an honorary board member of the Multiple Myeloma Research Foundation.^[14]
