Wine is an alcoholic beverage made from the fermentation of unmodified grape juice. The natural chemical balance of grapes is such that they ferment without the addition of sugars, acids, enzymes or other nutrients. Although other fruits like apples and berries can also be fermented, the resultant "wines" are normally named after the fruit (for example, apple wine or elderberry wine) and are generically known as fruit or country wine. Others, such as barley wine and rice wine (e.g. sake) are made from starch-based materials and resemble beer more than wine, while ginger wine is fortified with brandy. In these cases, the use of the term "wine" is a reference to the higher alcohol content, rather than production process. The commercial use of the English word "wine" (and its equivalent in other languages) is protected by law in many jurisdictions.

II. History
The earliest evidence suggesting wine production comes from archaeological sites in Georgia and Iran, dating from 6000 to 5000 BC. The archaeological evidence becomes clearer, and points to domestication of grapevine, in Early Bronze Age sites of the Near East, Sumer and Egypt from around the third millennium BC.

III. Grape varieties
Wine is usually made from one or more varieties of the European species, Vitis vinifera. When one of these varieties, such as Pinot Noir, Chardonnay, or Merlot, for example, is used as the predominant grape (usually defined by law as a minimum of 75 or 85%) the result is a varietal, as opposed to a blended wine. Blended wines are in no way inferior to varietal wines; some of the world's most valued and expensive wines from the Bordeaux, Rioja or Tuscany regions, are a blend of several grape varieties of the same vintage.

Wine can also be made from other species or from hybrids, created by the genetic crossing of two species. Vitis labrusca, Vitis aestivalis, Vitis rupestris, Vitis rotundifolia and Vitis riparia are native North American grapes, usually grown for eating in fruit form or made into grape juice, jam, or jelly, but sometimes made into wine, eg. Concord wine

Beer is the world's oldest and most popular alcoholic beverage. It is produced by the fermentation of sugars derived from starch-based material—the most common being malted barley; however wheat, corn, and rice are also widely used, usually in conjunction with the barley. Less widely used starch sources include millet, sorghum and cassava root in Africa, potato in Brazil, and agave in Mexico, among others.

I. Brewing
Beer is made by brewing. The essential stages of brewing are mashing, sparging, boiling, fermentation, and packaging. Most of these stages can be accomplished in several different ways, but the purpose of each stage is the same regardless of the method used to achieve it.

II. Ingredients
The basic ingredients of beer are water; a fermentable starch source, such as malted barley; and yeast. It is common for a flavouring to be added, the most popular being hops. A mixture of starch sources may be used, with the secondary starch source, such as corn, rice and sugar, often being termed an adjunct, especially when used as a lower cost substitute for malted barley.
