Hooch : Spurious Liquor Of Tamil Nadu’s
At least 34 people have died, and around 100 others have been hospitalised after consuming hooch, or spurious liquor, in Tamil Nadu’s Kallakurichi.
- Hooch is a commonly used term for poor quality alcohol, derived from Hoochinoo, a native Alaskan tribe that was known to produce very strong liquor.
- Unlike branded liquor which is produced in factories with sophisticated equipment and rigorous quality control, hooch is made in much more crude settings.
- All alcohol is produced using two basic processes: fermentation and distillation.
- When heated, yeast reacts with sugar (from grain, fruits, sugarcane, etc.) to ferment and produce a mixture containing alcohol.
- This is an age-old process, used to create beverages like beer or wine.
- As fermentation continues, and alcohol levels rise, conditions in the mixture become toxic for the yeast.
- Eventually, no more fermentation can take place. Thus, to make anything stronger (above 14-18% ABC), beverages need to be distilled.
- This is the process of physically separating alcohol from a fermented mixture using evaporation and condensation.
- Since different parts of the mixture have different boiling points, heating it up to the correct temperature makes it possible to separate only the alcohol from the water and other remnants.
- Distilled beverages, or spirits, are far more potent than any fermented beverage.
- The fermented mixture which is distilled contains more than just consumable alcohol (ethanol).
- It also contains methanol, an industrial alcohol which is highly toxic for human beings.
- Non-distilled alcoholic beverages like wine contain relatively harmless trace amounts of methanol.
- But during the distillation, both ethanol and methanol are concentrated.
- Thus, if done incorrectly, distillation can lead to an end product which contains high quantities of toxic methanol.
