Grapevines

Grapes are the fruit of a woody grape vine. Grapes can be eaten raw, or used for making wine, juice, and jelly/jam. Grapes in different colours; red, purple, white, and green are some examples. Today, grapes can be seedless, by using machines to pit the fruit. Wild grapevines are often considered a nuisance weed, as they cover other plants with their usually rather aggressive growth.

Raisins are the dried fruit of the grapevine, and the name actually comes from the French word for "grape."

Since the early 21st century in the United States and other countries, and the global functional food industry, there has been a fast-growing recognition of red grapes for their popularity, nutrient content and antioxidant qualities. This has given them commercial status as a "superfruit".

The leaves of the grapevine itself are considered edible (eatable). They are used to make dolmades.

Grapevines are used as food plants by the larvae of some Lepidoptera species.

[change] Distribution

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

The following list of top wine-producers shows the areas used to grow grapes for wine making^[1] ^[2]

Spain - 11,750 km²
France - 8,640 km²
Italy - 8,270 km²
Turkey - 8,120 km²
United States - 4,150 km²
Iran - 2,860 km²
Romania - 2,480 km²
Portugal - 2,160 km²
Argentina - 2,080 km²
Australia - 1,642 km²

Comparing diets among western countries, researchers have found that although the French usually eat more animal fat than other countries, the number of cases of heart disease remains low in France.^[3] Many scientists think this is because the French drink more red wine than other countries. Something in the grape helps lower the amount of cholesterol in the body. This helps prevent clogging of the arteries. Doctors do not recommend drinking a lot of red wine, but three or four glasses a week is good and encouraged.

Grapes of all colors offer benefits. Red wine offers health benefits that are not found in white wine. This is because many of the good nutrients are found in the skins of the grapes, and only red wine is fermented with the skins.

[change] White grapes

White grapes are derived from the red grape by evolution. Changes in two genes turn off creation of anthocyanin. Anthocyanin is what makes red grapes the color red.^[4].

[change] Raisins, currants, and sultanas

A raisin is any dried grape. A currant is a dried Zante grape. The name is a corruption of the French raisin de Corinthe (Corinth grape). A sultana was originally a raisin made from a specific type of grape of Turkish origin. The word is now used for raisins made from common North American grapes and chemically treated to resemble the traditional sultana.

Note that, while raisin is a French loanword, the word in French means the fresh fruit. Grappe (Where the English word grape comes from) means the bunch (as in une grappe de raisin).

Note also that currant has also come to mean to the blackcurrant and redcurrant. These two berries completely unrelated to grapes.
