The world of olive oil can sometimes be a little tricky to navigate and understand. Here are some technical terms you might come across and their meanings.
- Cold pressed:
that the oil was not heated over a certain temperature (usually 80 °F (27 °C)) during processing, thus retaining more nutrients and undergoing less degradation.
By-product of residual olive paste left after processing which still contains a variable percentage of water and oil depending on the processing method employed. Pomace is usually used by the extraction industry to obtain crude olive-pomace oil, or for other purposes.
- Early Harvest:
Oil made from olives at optimal ripeness at the beginning of the season.
