The animation contains basic chemistry of alcohol and wine making process, types of alcohol and their application. It covers the following :

Alcohol :
Alcohol are simple class of organic compounds, which are made up of only carbon, hydrogen and oxygen elements.
The general formula of alcohol is R-OH, where R represents an alkyl group made up of carbon and hydrogen in various proportions and -OH represents one or more hydroxyl groups.

The two simple alcohol are methyl alcohol, CH3OH (which is also known as methanol) and ethyl alcohol, C2H5OH (which is also called as ethanol)

Ethyl alcohol, or ethanol, C2H5OH, is a clear, colorless liquid, with a burning taste and characteristic, agreeable odor. Ethanol is the alcohol in such beverages as beer, wine, and brandy. Because of its low freezing point, it has been used as the fluid in thermometers for temperatures below -40 C (-40 F), the freezing point of mercury, and for other special low-temperature purpose, such as for antifreeze in automobile radiators.

Ethanol is normally concentrated by distillation of dilute solutions. Commercial ethanol contains 95 percent by volume of ethanol and 5 percent of water. Dehydrating agents remove the remaining water and produce absolute ethanol. Ethanol melts at -114.1 C (-173.4 F), boils at 78.5 C (173.3 F), and has a specific gravity of 0.789 at 20 C (68 F).
Wine Making : Ethanol is prepared on large scale by the fermentation of sugar or starch with the enzymes present in yeast. Molasses is cheap sources of sugar and it forms an excellent raw material for making ethanol. Ethanol is used in the preparation of red and white wine.
