Wine

Wine is an alcoholic beverage obtained from the fermentation (total or partial) of the vine fruit, specifically the grape (both red and white), or its must.

History

The history of wine dates back to ancient times. Fossil finds of vine branches (Vitis vinifera) have been discovered in lignite deposits in the Upper Valdarno region, dating back approximately 2 million years. Archaeological findings suggest that Vitis vinifera grew spontaneously in various regions, including the shores of the Caspian Sea and eastern Turkey.

The oldest evidence of wine production was found on the island of Sicily, where residues linked to the winemaking process were discovered in a jar from the Age of Copper, dating back to the beginning of the 4th millennium BC. This discovery represents one of the earliest known examples of wine production.

Production

Wine is produced through the alcoholic fermentation of grape juice or must. Fermentation occurs when yeasts transform the natural sugars present in the fruit into ethanol and carbon dioxide gas. The sugar and acid content of the grapes, specifically Vitis vinifera, are sufficient to initiate fermentation.

However, wine production is also influenced by environmental factors such as climate, latitude, altitude, hours of sunlight, and temperature. These conditions can vary significantly depending on the region, which is why wine production is often associated with places having a Mediterranean climate.

Global Production

Approximately 66% of the world's grape collection is dedicated to wine production, while the remaining 34% is consumed as fresh fruit. The cultivation of vineyards covers around 0.5% of the world's arable land and is concentrated in regions with a Mediterranean climate.

The top three wine-producing countries are Italy, France, and Spain, which account for half of the world's total wine production. Other recognized designations of origin include Rioja, La Mancha, Albariño, and many others.
