What is the difference between cold pressing and hot pressing?

Cold pressing is temperature controlled below 120°F (49°C) during the pressing process. It is used for oils with a more delicate flavor that could be negatively affected by the heat of regular hot pressing, such as virgin olive oil.
Hot pressing generates heat in the range of 140 to 210 degree F, and this heat is not regulated. However, the oil output is higher as applying this method for oil pressing.
