Refer to @Noddy74 Straw. Below just additional notes/facts I found interesting on Olive Oil from the prospectus.

Olive oil is the broad term used to describe the oil extracted from the fruit of an olive tree. Extra virgin olive oil is the highest quality grade of olive oil. Most of the olive oil produced by Cobram Estate Olives is extra virgin olive oil. It is simply the fresh, natural juice extracted from the olive fruit and is made with minimal processing, which preserves both its nutritional benefits and complex flavours. In Australia, products labelled simply as “olive oil” primarily consist of refined olive oil, which are made by refining (further processing) lower quality olive oils.

Olive oil production 

The main olive oil producing countries are Spain, Italy, Greece, Tunisia, and Turkey. In recent times, the olive tree has spread outside the Mediterranean and is now grown and harvested in many countries including Argentina, Australia, Chile, South Africa, Peru, USA, Japan, and China. 

Olive oil shelf life 

Olive oil has a relatively long shelf life, and this allows for the orderly sale of stock over one to two growing seasons. However, unlike wine, olive oil does not improve with age. Over time olive oil, like any other cooking oil, will oxidise, eventually leading to the product becoming rancid. As a result, olive oil cannot be stored for extended periods and global stock levels are continuously being depleted and replenished. Exposure to light, heat, and oxygen will accelerate the process of oxidation.

Sustainable olive farming practices 

Olive trees have one of the lowest water requirements compared to many permanent crops such as most nut and fruit trees. In addition, the International Olive Council estimates that producing one litre of extra virgin olive oil captures an average of 10.65kg of CO2 from the atmosphere, with one hectare of the average olive grove neutralising the carbon footprint of one person. Olive crops are the only mainstream edible oil crop which acts as a carbon sink. The most efficient crop in terms of use of water, nitrogen, and phosphorus fertilisers.
