For many many years, going back to the ancient Greeks and Romans, people have used presses to extract olive oil from the olive, the press is used to separate the olive oil and vegetation water from the solid body of the olive. Once these two have been separated, a decanter is used to separate the oil from the water. In able to gain a fine olive oil, there is a process that must be used before the olive is pressed.

First of all the olives should be harvested and the bad olives removed from the bunch. The olives are then put under a special stone called millstone or in some areas a ground stone. The olives should stay under the stone for just over a half an hour to turn them into a paste, also to guarantee that the paste collects the right aromas and smell that come from the fruit enzymes and forms into the olive oil drops.

Once this process is over and the olives are converted into a paste, the past is spread onto fiber disks. Once fully and evenly spread onto the disks the paste is placed into the press machine. The press will then apply the necessary pressure needed to compact the past and percolate the oil forms and the water in the paste. Water is placed in the sides of the press to simplify the process of percolation.

When the pressing is finished the oil and water must be separated to achieve a pure olive oil. With the traditional process both the oil and the water a put into a decanter but there is another process that is a lot quicker than the decanter. The faster process is one called vertical centrifuge and is used to complete the whole process of oil and water separation a lot faster.

Once the extraction process has been fully completed, the cleaning process begins. This process has to be done thoroughly because if not the remaining past will begin to ferment on the millstones and disks causing other oils to get contaminated and change the taste of the oil completely. Every time new oil is to be made, a complete check that the press and millstones are completely clean must be done.

Using this traditional method of making olive oil has some advantages, these include that the olives are very well ground and easily pomaced. But the complication at the time of cleaning, the hours of extra manual labor and the time it takes to wait after the harvesting to the time of pressing the olives to make the oil can be classed as disadvantages when using this method, and because of this people have invented other methods that save time.
