71-551: Elbling ( German: [ˈɛlplɪŋ] ) is a variety of white grape (sp. Vitis vinifera ) which today is primarily grown in the upstream parts of the Mosel region in Germany and in Luxembourg , where the river is called Moselle . The variety has a long history, and used to cover much of Germany's vineyards from medieval times and was that country's most cultivated variety until
142-516: A gelling agent , meaning when the pectin chains combine, they create a network that results in a gel. The strength and effectiveness of the side chains and the bonds they form depend on the pH of the pectin, the optimal pH is between 2.8 and 3.2. Marmalade is a fruit preserve made from the juice and peel of citrus fruits boiled with sugar and water. It can be produced from lemons, limes, grapefruits, mandarins, sweet oranges, bergamots and other citrus fruits, or any combination thereof. Marmalade

Winemaking from red and white grape flesh and skins produces substantial quantities of organic residues, collectively called pomace (also "marc"), which includes crushed skins, seeds, stems, and leaves generally used as compost . Grape pomace – some 10–30% of the total mass of grapes crushed – contains various phytochemicals , such as unfermented sugars, alcohol, polyphenols , tannins , anthocyanins , and numerous other compounds, some of which are harvested and extracted for commercial applications (a process sometimes called "valorization" of
284-505: A chemical to adjust the pH; and/or an antifoaming agent . In the European Union , the jam directive (Council Directive 79/693/EEC, 24 July 1979) set minimum standards for the amount of "fruit" in jam, but the definition of fruit was expanded to take account of several unusual kinds of jam made in the EU. For this purpose, "fruit" is considered to include fruits that are not usually treated in
355-478: A culinary sense as fruits, such as tomatoes, cucumbers , and pumpkins; fruits that are not normally made into jams; and vegetables that are sometimes made into jams, such as rhubarb (the edible part of the stalks), carrots, and sweet potatoes . This definition continues to apply in the new directive, Council Directive 2001/113/EC of 20 December 2001 relating to fruit jams, jellies and marmalades and sweetened chestnut purée intended for human consumption. Extra jam

The consumption of grapes and raisins presents a potential health threat to dogs. Their toxicity to dogs can cause the animal to develop acute kidney failure (the sudden development of kidney failure) with anuria (a lack of urine production) and may be fatal. Christians have traditionally used wine during worship services as
497-417: A distinctive bitter taste which it imparts to the preserve. Fruit preserves are used in many food preparations and recipes; some examples include: In general, jam is produced by taking mashed or chopped fruit or vegetable pulp and boiling it with sugar and water. The proportion of sugar and fruit varies according to the type of fruit and its ripeness, but a rough starting point is equal weights of each. When
568-658: A dominant position of wine-making in human culture dates from 8,000 years ago in Georgia . The oldest known winery, the Areni-1 winery , was found in Armenia and dated back to around 4000 BC. By the 9th century AD, 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
639-503: A means of remembering the blood of Jesus Christ which was shed for the remission of sins . Christians who oppose the partaking of alcoholic beverages sometimes use grape juice as the "cup" or "wine" in the Lord's Supper . The Catholic Church continues to use wine in the celebration of the Eucharist because it is part of the tradition passed down through the ages starting with Jesus Christ at
710-416: A minimum percentage of water-soluble solids. Jams "shall be the product made by boiling fruit, fruit pulp or canned fruit to a suitable consistency with water and a sweetening ingredient", jellies "shall be the product made by boiling fruit juice or concentrated fruit juice that is free from seeds and pulp with water and a sweetening ingredient until it acquires a gelatinous consistency". In Canada, fruit jam

#1732881337997852-535: A multitude of products such as jams, juices, vinegars and oils. Commercially cultivated grapes are classified as either table or wine grapes. These categories are based on their intended method of consumption: grapes that are eaten raw (table grapes), or grapes that are used to make wine (wine grapes). Table grape cultivars normally have large, seedless fruit and thin skins. Wine grapes are smaller (in comparison to table grapes), usually contains seeds, and have thicker skins (a desirable characteristic in making wine). Most of
923-465: A number of plums are among these fruits. Because of this shorter cooking period, not as much pectin will be released from the fruit, and consequently conserves, particularly if home-cooked, will sometimes be slightly softer set than some jams. There is an alternative definition of a conserve: a preserve made from a mixture of fruits or vegetables. Conserves in this sense may also include dried fruit or nuts. Fruit butter , in this context, refers to
994-478: A pastry or dessert, whereas more savory and acidic preserves made from " vegetable fruits " such as tomato, squash or zucchini , are eaten alongside savory foods such as cheese, cold meats, and curries. There are several techniques of making jam, with or without added water. One factor depends on the natural pectin content of the ingredients. When making jam with low-pectin fruits like strawberries, high-pectin fruit like orange can be added, or additional pectin in
1065-546: A process similar to that used for making jam, with the additional step of filtering out the fruit pulp after the initial cooking. Good jelly is clear and sparkling and has a fresh flavor of the fruit from which it is made. It is tender enough to quiver when moved but holds angles when cut. The characteristic clarity and jellied consistency of a jelly are qualities it shares with the gelatin-based dessert also called jelly in some places. High pectin fruits such as quinces, apples, or redcurrants are used for making jelly. In
1136-421: A process where the whole fruit is forced through a sieve or blended after the heating process. Fruit butter are generally made from larger fruits, such as apples, plums, peaches, or grapes. Cook until softened and run through a sieve to give a smooth consistency. After sieving, cook the pulp ... add sugar and cook as rapidly as possible with constant stirring.… The finished product should mound up when dropped from
1207-456: A relatively high phenolic content among dark grapes. In muscadine skins, ellagic acid , myricetin , quercetin , kaempferol , and trans-resveratrol are major phenolics. The flavonols syringetin , syringetin 3-O-galactoside, laricitrin and laricitrin 3-O-galactoside are also found in purple grape but absent in white grape. Muscadine grape seeds contain about twice the total polyphenol content of skins. Grape seed oil from crushed seeds
1278-486: A replaceable tightly-fitting lid can be used. Other methods of packaging jam, especially for industrially produced products, include cans and plastic packets, especially used in the food service industry for individual servings. Under the Processed Products Regulations (C.R.C., c. 291), jams, jellies, citrus marmalade, and preserves are defined. Each must contain a minimum percentage of the named fruit and
1349-626: 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
1420-424: A spoon, but should not cut like jelly. Nor should there be any free liquid. Fruit curd is a dessert topping and spread usually made with lemon, lime , orange, or raspberry . The basic ingredients are beaten egg yolks, sugar, fruit juice and zest which are gently cooked together until thick and then allowed to cool, forming a soft, smooth, flavorful spread. Some recipes also include egg whites or butter. In
1491-523: A suitable shelf life. Mango chutney, for example, is mangoes reduced with sugar. Confit , the past participle of the French verb confire , "to preserve", is applied both to preservation of meats, and to fruits or vegetables seasoned and cooked with honey or sugar till jam-like. Savory confits, such as those made with garlic or fennel, may call for an oil, such as virgin olive oil, as the preserving agent. Konfyt ( Afrikaans : "jam" or "fruit preserve" )

Commandaria , a sweet dessert wine from Cyprus, is the oldest manufactured wine in the world with origins as far back as 2000 BC. In North America, native grapes belonging to various species of the genus Vitis proliferate in
1633-414: 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. Anthocyanins and other pigment chemicals of
1704-407: A vacuum which both helps prevent spoilage and pulls down a tamper-evident "safety button" when used. The high sugar content makes jam keep for exceedingly long times before unsealing the packaging, and for a long time at room temperature after opening, as fruit preserves are typically of low water activity . Glass or plastic jars are often used to store jam that is not all to be used at once, as
1775-1605: A wine which has been compared to a lighter and more tart version of Silvaner . Varietal Elbling wine is most commonly found in Luxembourg.

The cultivation of grapes began approximately 8,000 years ago, and the fruit has been used as human food throughout its history. Eaten fresh or in dried form (as raisins , currants and sultanas ), grapes also hold cultural significance in many parts of
1917-470: Is a type of jam eaten in Southern Africa. It is made by boiling selected fruit or fruits (such as strawberries, apricots, oranges, lemons, watermelons, berries, peaches, prickly pears, or others) and sugar, and optionally adding a little ginger to enhance the flavor. The origin of the term is obscure, but it is theorized that it came from the French. The word is also based on the French term confiture via
1988-510: Is achieved through the action of natural or added pectin . It is then sealed in containers. Jam making became "a great new industry" in 19th century England, at which point English jam makers were jam makers for the world, thriving after the repeal of sugar duties in 1874. Pectin is mainly D-galacturonic acid connected by α (1–4) glycosidic linkages. The side chains of pectin may contain small amounts of other sugars such as L-fructose, D-glucose, D-mannose, and D-xylose. In jams, pectin thickens
2059-644: Is an offspring of Gouais blanc (also known as Heunisch) and a cross between Traminer and some unidentified variety. This parentage is consistent with Elbling being an ancient grape variety, and incidentally, it is the same parentage as for Riesling . This parentage and history makes it likely that Elbling originated somewhere in the Rhine area. Elbling tends to give musts low in sugar, and wines high in acid and fairly neutral in character, which makes it primarily used for sparkling wine , such as non-varietally labelled Mosel Sekt . When made into varietal still wine, it gives
2130-704: Is believed that the most widely planted variety is Sultana , also known as Thompson Seedless, with at least 3,600 km (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 . 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). The sweetness of grapes depends on when they are harvested, as they do not continue to ripen once picked. While almost all of them belong to
2201-609: Is categorized into two types: fruit jam and fruit jam with pectin . Both types contain fruit, fruit pulp or canned fruit and are boiled with water and a sweetening ingredient. Both must have 66% water-soluble solids. Fruit jam and fruit jam with pectin may contain a class II preservative , a pH adjusting agent or an antifoaming agent . Both types cannot contain apple or rhubarb fruit. Though both types of jam are very similar, there are some differences in fruit percent, added pectin, and added acidity . Fruit jam must have at least 45% fruit and may contain added pectin to compensate for

It is distinguished from a jelly by containing pieces of fruit peel. The benchmark citrus fruit for marmalade production in Britain is the bitter Spanish Seville orange , Citrus aurantium var. aurantium , prized for its high pectin content, which gives a good set. The peel has
2343-487: Is not the case, the more usual generic term is 'jam'. The singular preserve or conserve is used as a collective noun for high fruit content jam, often for marketing purposes. Additionally, the name of the type of fruit preserves will also vary depending on the regional variant of English being used. Cheong is a name for various sweetened foods in the form of syrups, marmalades, and fruit preserves in Korean cuisine. It

The second commercial process involves the use of a vacuum vessel, where the jam is placed under a vacuum, which has the effect of reducing its boiling temperature to anywhere between 65 and 80 °C depending on the recipe and
2556-577: Is used as a tea base, as a honey-or-sugar substitute in cooking, and as a condiment. There are liquid varieties such as maesil-cheong ( plum syrup ), jam -like varieties such as yuja-cheong ( yuja marmalade ), and conserve -like varieties such as mogwa-cheong (preserved quince ). A chutney is a relish of Indian origin made of fruit, spices and herbs. Although originally intended to be eaten soon after preparation, modern chutneys are often made to be sold, so they require preservatives – often sugar and vinegar – to ensure they have

Grape seed oil, including tocopherols ( vitamin E ) and high contents of phytosterols and polyunsaturated fatty acids such as linoleic acid , oleic acid , and alpha-linolenic acid . Resveratrol, a stilbene compound, is found in widely varying amounts among grape varieties, primarily in their skins and seeds. Muscadine grapes have about one hundred times higher concentration of stilbenes than pulp. Fresh grape skin contains about 50 to 100 micrograms of resveratrol per gram. Comparing diets among Western countries, researchers have discovered that, although French people tend to eat higher levels of animal fat,

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
2840-448: The Dutch confident (meaning candied fruit). A conserve , or whole fruit jam , is a preserve made of fruit stewed in sugar. The making of conserves can be trickier than making a standard jam; it requires cooking or sometimes steeping the fruit in the hot sugar mixture for just long enough to allow the flavor to be extracted from the fruit, and sugar to penetrate it, but not so long that

The term is sometimes used for a jam or preserve with no added sugar, but there are many foodstuffs described as "fruit spreads" by leading manufacturers that do contain added sugar. Jam refers to a product made of whole fruit cut into pieces or crushed, then heated with water and sugar until it reaches "jelling" or "setting" point, which
3053-531: The United States), but the word is now applied to raisins made from either white grapes or red grapes that are bleached to resemble the traditional sultana. 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 . Grape juice that has been pasteurized, removing any naturally occurring yeast, will not ferment if kept sterile, and thus contains no alcohol. In

Fruit jellies may be used in a meal or dish in a similar way to jam. Some jellies, such as redcurrant , or mint , are classic accompaniments to roasted meats such as turkey, game, and lamb. Pectin is essential to the formation of jelly because it acts as
3195-492: The aroma in wine is from the skin. Wine grapes tend to have a high sugar content. They are harvested at peak sugar levels (approximately 24% sugar by weight.) In comparison, commercially produced "100% grape juice" made from table grapes are normally around 15% sugar by weight. In most of Europe and North America, dried grapes are referred to as "raisins" or the local equivalent. In the UK, three different varieties are recognized, forcing

As of 2006, there were 583 hectares (1,440 acres) of Elbling vineyards in Germany, which made it the country's 23rd most grown variety of grape. Of that vineyard surface, 575 ha or 98.6% was found in the Mosel region In the same year, there were 122.9 hectares (304 acres) of Elbling grown in Luxembourg. It has been speculated that Elbling
3337-417: The end result desired. The lower boiling temperature enables the water to be driven off as it would be when using the traditional open pan method, but with the added benefit of retaining more of the volatile flavor compounds from the fruit, preventing caramelization of the sugars, and of course reducing the overall energy required to make the product. However, once the desired amount of water has been driven off,
3408-500: The final product via cross-linking of the large polymer chains. Recipes without added pectin use the natural pectin in the fruit to set. Tart apples , sour blackberries , cranberries , currants, gooseberries , Concord grapes , soft plums , and quinces work well in recipes without added pectin. Other fruits, such as apricots, blueberries, cherries, peaches, pineapple, raspberries, rhubarb, and strawberries are low in pectin. In order to set, or gel, they must be combined with one of
3479-460: The finished product must not be less than that laid down for the manufacture of extra jam. The U.S. Food and Drug Administration (FDA) published standards of identity in 21 CFR 150, and treats jam and preserves as synonymous, but distinguishes jelly from jams and preserves. All of these are cooked and pectin-gelled fruit products, but jellies are made from fruit juice, without seeds and pulp, while jams and preserves are gelled fruit that may include
3550-411: The form of pectin powder, citric acid or citrus peels. Often the fruit will be heated gently in a pan to release its juices (and pectin), sometimes with a little added water, before the sugar is added. Another method is to macerate the fruits in sugar overnight and cook this down to a syrup. The term preserves is usually interchangeable with jams even though preserves contain chunks or pieces of
3621-515: The fruit breaks down and liquefies. This process can also be achieved by spreading the dry sugar over raw fruit in layers, and leaving for several hours to penetrate into the fruit and soak the water out, then heating the resulting mixture to bring it just to the set point. As a result of this minimal cooking, some fruits are not particularly suitable for making into conserves, because they require cooking for longer periods to avoid faults such as tough skins and spoiling. Currants and gooseberries , and

Closely related names include: chutney , confit , conserve , fruit butter , fruit curd , fruit spread , jelly , cheese , leather and marmalade . Some cookbooks define preserves as cooked and gelled whole fruit (or vegetable), which includes a significant portion of the fruit. In the English-speaking world, the two terms are more strictly differentiated and, when this

Freezer jam is uncooked (or cooked less than 5 minutes), then stored frozen. It is popular in parts of North America for its very fresh taste. [REDACTED] The category of fruit preserve referred to as a jelly (from the French gelée ) is a clear or translucent fruit spread made by
3905-560: The incidence of heart disease remains low in France. This phenomenon has been termed the French paradox and is thought to occur due to the protective benefits of regularly consuming red wine, among other dietary practices. Alcohol consumption in moderation may be cardioprotective by its minor anticoagulant effect and vasodilation . Although adoption of wine consumption is generally not recommended by health authorities, some research indicates moderate consumption, such as one glass of red wine
3976-426: The jam still needs to be heated briefly to 95 to 100 °C (203 to 212 °F) for safety, to kill pathogens that would otherwise proliferate. During commercial filling it is common to use a flame to sterilize the rim and lid of jars to destroy any yeasts and molds which could cause spoilage during storage. Steam is commonly injected immediately before lidding; when the steam condenses after lidding it creates
4047-421: The larger family of polyphenols in purple grapes are responsible for the varying shades of purple in red wines. Grapes are typically an ellipsoid shape resembling a prolate spheroid . Raw grapes are 81% water, 18% carbohydrates , 1% protein , and have negligible fat (table). A 100-gram ( 3 + 1 ⁄ 2 -ounce) reference amount of raw grapes supplies 288 kilojoules (69 kilocalories) of food energy and
4118-496: The mixture reaches a temperature of 104 °C (219 °F), the acid and the pectin in the fruit react with the sugar, and the jam will set on cooling. Most home cooks work by trial and error rather than temperature measurement, bringing the mixture to a "fast rolling boil ", watching to see if the seething mass changes texture , and dropping small samples on a plate to see if they run or set. Commercially produced jams are usually produced using one of two methods. The first

The names of the black and red currant, now more usually blackcurrant and redcurrant , two berries unrelated to grapes, are derived from this use. Some other fruits of similar appearance are also so named, for example, Australian currant, native currant, Indian currant. A sultana was originally a raisin made from Sultana grapes of Turkish origin (known as Thompson Seedless in

Jelly with pectin must be made with a minimum of 62% water-soluble solids and a minimum of 32% juice of the named fruit, and may contain an acid ingredient that compensates for the lack in the natural acidity of the fruit; the additional juice of another fruit; a gelling agent; food color; a Class II preservative (such as benzoates , sorbates , or nitrites );
4331-587: The natural pectin level found in the fruit. Fruit jam with pectin need only contain 27% fruit and is allowed to contain added acidity to compensate for the natural acidity of the fruit. In Canada , the Food and Drug Regulations of the Food and Drugs Act of Canada categorizes jelly into two types: jelly, and jelly with pectin . Jelly may be made from the fruit, the fruit juice, or a fruit juice concentrate, and must contain at least 62% water-soluble solids. Jelly may contain an acid ingredient that makes up for any lack in

Anthocyanins tend to be the main polyphenolics in purple grapes, whereas flavan-3-ols (i.e. catechins ) are the more abundant class of polyphenols in white varieties. Total phenolic content is higher in purple varieties due almost entirely to anthocyanin density in purple grape skin compared to absence of anthocyanins in white grape skin. Phenolic content of grape skin varies with cultivar , soil composition, climate, geographic origin, and cultivation practices or exposure to diseases, such as fungal infections. Muscadine grapes contain

It is produced by crushing unripened grapes, collecting and salting the juice, simmering it to remove foam, and then storing it with a layer of olive oil to prevent contamination and oxidation. It is then used as an acidic ingredient in salads and stuffed vegetables. Unripened husrum grapes sent from Ashkelon to Egypt are mentioned in
4544-452: The relatively cold climates of northeastern United States and southern Ontario . 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). Grapes are eaten raw, dried (as raisins, currants and sultanas), or cooked. Also, depending on grape cultivar, grapes are used in winemaking. Grapes can be processed into
4615-461: 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
4686-443: 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. 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
