Ethanol is the primary component of alcoholic beverages. Whether it is beer, wine, or spirits, it is always ethanol responsible for the psychoactive effect. The only difference is the concentration and flavor.
However, ethanol can be the brilliant source of energy to replace hydrocarbons, because ethanol is the renewable source of energy as it is produced by the fermentation of sugars and sugars are extracted from plants.
Step 1: Making Substrate for the Fermentation.
It is literally as easy as making a cup of tea.
All you need to do is to bring the water to boil and dissolve regular sugar(sucrose) at the ratio 400grams of sugar per 1 liter of water. Preferably you should use distilled water however, tap water will work just fine with some acidification. It is important for the substrate to be between 4.5 and 5.5 pH otherwise biochemical process may not be possible.
After the sugar dissolves completely, leave the solution to cool down to below 40 degrees centigrade, and add brewing yeast following the manufacturer's instruction. Temperatures above 40 can be harmful to yeast!
After the addition of yeast, cover the fermenter with the paper towel of cheesecloth and leave it to ferment for about 7 days.
Step 2: Extraction of Ethanol From the Substrate.
Ethanol can be extracted by fractional distillation.
