Grape (fruit and vine)

Characteristics and varieties

Grapevines produce berries with thin skins surrounding a juicy interior; some cultivars contain seeds while others have been bred to be seedless. Varieties are often classified as table grapes, wine grapes and raisin grapes according to traits such as sugar content, acidity, skin thickness and flavor intensity. Many modern cultivars emphasize larger berries, seedlessness and resistance to disease, while traditional wine varieties are selected for balanced sugars and aromatic compounds concentrated in the skins.

History and cultivation

Humans have cultivated grapevines for several thousand years, originally in the Near East and Mediterranean regions, and later across Europe, Asia and the Americas. Cultivation—viticulture—includes pruning, trellising and choosing appropriate rootstock to suit soil and climate. Production methods differ for wine grapes (which may be left to concentrate sugars and flavors) and table grapes (often harvested to maximize appearance and shelf life). In some areas wild vines are persistent and can overgrow other vegetation.

Culinary and commercial uses

Grapes are processed into a wide range of foods and beverages. They are pressed and fermented to make wine, squeezed for juice, and cooked into preserves such as jelly and jam. Dried grapes are known as raisins and are prized for baking and long-term storage. Grape leaves are also used in regional cuisines to wrap fillings in dishes like dolmades. Commercial sectors include fresh-market table grapes, winemaking and dried-fruit processing, each with distinct harvest and handling practices.

Nutrition and health aspects

Grapes provide carbohydrates (mainly sugars), water and small amounts of vitamins and minerals. Red and purple varieties contain pigment compounds in their skins that act as plant antioxidants. In recent decades consumers and food industries, particularly in the United States and elsewhere, have emphasized these nutrients and antioxidants when marketing grape products. Scientific discussion about health effects focuses on moderation and the difference between whole fruit and concentrated extracts.

Ecology, pests and notable facts

Grapevines are ecologically important as food for wildlife and as host plants: the larvae of various insects, including many species of Lepidoptera, feed on grape leaves. Cultivated vines face pests and diseases such as fungal infections, insects and viruses, which viticulturists manage with pruning, sanitation and targeted treatments. Beyond agriculture, grapes and their products hold cultural significance in art, ritual and cuisine around the world.

• Common grape products: fresh grapes, wine, juice, jelly, jam, raisins.
• Culinary note: grape leaves are edible and used in stuffed preparations.
• Horticulture tip: clonal selection and rootstock choice shape vine vigor and fruit quality.
