How much olive oil can be produced from 5 liters of olives?

The correct understanding of the olive oil extraction process reveals that the typical yield of olive oil from olives can vary based on several factors, including the type of olive, ripeness, and extraction method. Generally, the average yield of olive oil from fresh olives ranges between 10% to 25%.

Considering this average yield, if we take the lower end at around 10%, from 5 liters of olives, you would expect to extract approximately 0.5 liters of oil. On the higher end, at about 20%, it could be around 1 liter. Hence, extracting 1 liter from 5 liters of olives is a plausible estimation.

This estimation aligns with the choice of 1 liter being the most accurate, capturing the realistic average yield typically seen in oil extraction processes. Other figures provided either exceed the reasonable yield achievable or are significantly lower than what can be expected based on industry practices.
