Question: How long is the fermentation process to produce ethanol?
Answer: The duration of fermentation depends on the level of starches, or sugars, present in the crop being used to produce the ethanol. One example would be corn which takes 3-5 days to ferment. Essentially the higher the starch or sugar content the longer it will take the yeast to fully process all of it into ethanol and carbon dioxide. To get a better picture for a specific crop research the quantity of sugars and starches present in a given amount and compare it to the amount present in corn and then use the 3-5 days timeline as a baseline for comparison.
