Grapes, wine and other derivatives. OTA content. CHAPTER 6 GRAPES, WINE AND OTHER DERIVATIVES. OTA CONTENT 6.1. WORLD-WIDE PRODUCTION OF GRAPES, WINE AND OTHER GRAPE- DERIVATIVES Grape is the fruit of a vine in the family Vitaceae (Table 7). It is commonly used for making grape juice, wine, jelly, wine, grape seed oil and raisins (dried grapes), or can be eaten raw (table grapes). Table 7. Scientific classification of grapes. Kingdom: Plantae Division: Magnoliophyta Class: Magnoliopsida Order: Vitales Family: Vitaceae Genus: Vitis Many species of grape exist including: • Vitis vinifera, the European winemaking grapes. • Vitis labrusca, the North American table and grape juice grapes, sometimes used for wine. • Vitis riparia, a wild grape of North America, sometimes used for winemaking. • Vitis rotundifolia, the muscadines, used for jelly and sometimes wine. • Vitis aestivalis, the variety Norton is used for winemaking. • Vitis lincecumii (also called Vitis aestivalis or Vitis lincecumii), Vitis berlandieri (also called Vitis cinerea var. helleri), Vitis cinerea, Vitis rupestris are used for making hybrid wine grapes and for pest-resistant rootstocks. 73 CHAPTER 6 . The main reason for the use of most V. vinifera varieties in wine production is their high sugar content, which after fermentation, produce a wine with an alcohol content of 10 % or slightly higher. Grape varieties of V. vinifera have a great variation of composition. Skin pigment colours vary from greenish yellow to russet, pink, red, reddish violet or blue-black. The colour of red wines comes from the skin, not the juice. The juice is normally colourless, though some varieties have a pink to red colour.
