Winemaking

Winemaking or vinification is the production of wine, starting with the selection of the fruit, its fermentation into alcohol, and the bottling of the finished liquid. The history of wine-making stretches over millennia. The science of wine and winemaking is known as oenology. A winemaker may also be called a vintner. The growing of grapes is viticulture and there are many varieties of grapes.

History

Winemaking dates back to at least the second millennium BC, with the earliest archaeological evidence of wine grapes dated to 6000 BC. The earliest evidence of winemaking has been found in the Caucasus region and the Middle East where the wild grape Vitis vinifera is indigenous.

Process

The basic process of winemaking involves the fermentation of crushed grapes using various types of yeast. Yeast consumes the sugars in the grapes and converts them into alcohol. Different varieties of grapes and strains of yeasts produce different styles of wine.

Stages of winemaking

There are five basic stages to the wine making process which begins with harvesting and ends with bottling the wine. These stages are: harvesting, crushing and pressing, fermentation, clarification, and aging and bottling.

Winemaking techniques

There are many winemaking techniques, which can be classified into two general categories: traditional and modern. Traditional winemaking techniques have been passed down through generations and are still used today. Modern winemaking techniques involve the use of technology and scientific advancements.
