Grain Based Ethanol and its Growth in India !

Grain based ethanol or Grain alcohol is a purified form of ethanol made from the distillation of fermented grain. The ethanol is produced by fermenting sugars in the grain by yeast prior to repeated distillation or rectification. It is also used to refer to any ethanol produced from grain or other agricultural origin.

Grain based ethanol is used for the production of white spirits such as gin and vodka but also as a base for a wide range of flavoured alcoholic beverages. It is a colorless liquid addressed as a ‘neutral spirit’ i.e. bereft of added flavor. The chemical composition of C2H5OH makes it a flammable liquid.

Grain alcohols are known to act as depressants and a neurotoxin to the central nervous system. They find their application in alcoholic beverages, recreational drugs, solvents, antiseptics, fuels, and various industrial purposes.

The Growing Demand for Grain Based Ethanols

One of the factors responsible for the growing acceptance of grain-based alcohol in india is the inconsistency in Molasses’ prices. Until now, Molasses have been traditionally dominant in the production of alcohol in the Indian Made Foreign Liquor (IMFL) market. Now, however, the trend of using grain-based alcohol is exponentially growing. According to Praj industries - one of the leading Ethanol plant manufacturers in Asia, the grain-based variety of all potable alcohol produced in India has grown to 10% from a meager 2% to 3%. It is expected to further reach 22% in the next 5 years. (1)

Is Grain Alcohol 100% Pure?

Grain alcohol is commonly bottled in two versions, 75.5 percent ABV and 95 percent ABV. There is no 100 percent ABV grain alcohol for human consumption because of azeotropic effects during the distillation process. Such concentration is considered too easy for people to get alcohol poisoning.

Abundant Availability of Grains in India Makes it A Popular Choice

Alcohol from grains is found to be better in quality, but more expensive than the ones made from molasses. However, grain-based ethanol plants can find additional income source in one of the byproducts of grain-based distilleries - the animal feed. This has prompted more companies to set grain ethanol plants. This will also mean that we can get better quality alcohol.

As oil companies increase the use of ethanol for blending with petrol, prices of molasses-based ethanol have increased. As a result, the IMFL manufacturers frequently switch between grain-based and molasses-based alcohol depending upon its prices.

The government plans to allow food grains during surplus production years to be used for the production of ethanol that can be blended with petrol, in an attempt to broaden the availability of raw materials needed for Bioethanol production.

Pune-based Praj Industries, leaders in Industrial production of ethanol, have covered 80% of the dryer market in the past few years. The dryer technology, used for drying the wet waste generated by the grain-based distilleries has made it possible for the distilleries to cross-subsidize the production cost of grain alcohol.
