Petra Olives
Petra Estate is located in Yallingup, on 31 acres of gently sloping land, in WA's renowned food and wine Margaret River region. Petra Estate opened to the public in February 2007.
Petra's 1200 olive trees were first planted in 1999, along with the creation of lovely grounds, including Petra Accommodation and three dams.
Petra Premium Cold-Pressed Extra Virgin Olive Oils are masterful blends of Italian, Spanish, French & Greek olive varieties grown in the temperate Margaret River region climate.
Frantoio - Tuscany, Italy. Small/medium fruit with a high yield. Ripens mid/late season with a high oil content.

Note: due to increasing demand for Petra's high quality extra virgin olive oils, Petra occasionally sources from other high quality Western Australian olive groves, to expertly blend to create Petra's unique Extra Virgin Olive Oils.
Pressing Extra Virgin Olive Oil
Different varieties of olives ripen at different times in the season and individual olive trees may even bear fruit of varying ripeness.
Petra Estate offers the highest quality Extra Virgin Olive Oil by ensuring that
- olives are carefully selected when they are ready for pressing
- olive varieties are cold-pressed separately to ensure they reach the perfect level of ripeness for the desired style
- the oil produced is expertly blended to create the Extra Virgin Olive Oils that are unique to Petra Olive Oil Estate.
At Petra Olive Oil modern technology and traditional methods are used. We operate our boutique Olive Press with small batches to ensure the exacting standards of 'Extra Virgin' are met. This involves the crushing of the fruit by hammermill, a mixing process ('malaxation') to separate the oil molecules from the water, then extraction by centrifuge to separate the oil from the waste remnants of the fruit.
The final phase of cleaning the oil and further separation from water is achieved in some systems through a vertical centrifuge followed by filtering. At Petra our state-of-the-art Olive Press utilises the natural and gentle process of gravity separation in a glass decanter known as the 'Florentine Vase'.
By limiting the exposure to agitation, this process fully preserves the fresh flavours and taste of the oil as well as the unique health benefits (high polyphenols / antioxidants) that can only be gained from a premium extra virgin olive oil.
The finished product is stored in vaccum-sealed stainless steel tanks to settle for about six weeks.
Healthy Polyphenols
What are Polyphenols?
The flavenoid polyphenols (antioxidants) in olive oil are natural antioxidants that contribute to a bitter taste, astringency, and resistance to oxidation. Beneficial effects range from healing sunburn to lowering cholesterol, blood pressure, and risk of coronary disease.
Olive oil is the only vegetable oil that contains perceptible amounts of polyphenols.
What is the Polyphenol Content of Olive Oil?
- Petra Extra Virgin Olive Oils: 350-500+ppm
- Most Extra Virgin Olive Oils: 50-250ppm
- Ordinary Olive Oil: up to 50ppm (lower grades including imported oils sold in Australia)
Factors that drive these levels include the olive cultivar, degree of ripeness, production and extraction technologies employed, and the age of the oil.
Petra Extra Virgin Olive Oils are unfiltered and completely unadulterated and bottled in small batches to preserve the highest possible polyphenol (antioxidant) levels. This often results in a cloudy appearance and robust flavour. Petra only sells current season EVOO to ensure quality and freshness.
Olive Oil Terminology
Extra Virgin - Extra Virgin Olive Oil means that olive oil has been extracted using the first cold press of olives. All Petra Extra Virgin Olive Oil is first cold-pressed.
Low Acidity - The best olive oil has a natural level of low acidity. Extra virgin olive oil is produced using cold-pressed, chemical-free processes that involves only cold pressure or cold centrifugation, keeping acidity low. According to the International Olive Oil Council extra virgin olive oil must have an acidity of less than 0.8%. Petra Extra Virgin Olive Oil is 0.2% acidity.
First Pressed - refers to the olives being pressed on the first round of extraction. Petra Extra Virgin Olive Oil uses olives that are only pressed once.
Cold Pressed - the cold pressed method indicates that no heat or chemical additives are used to extract the oil from the olives, which can alter and destroy the flavours, aromas and nutritional value of the olive oil
Cold - refers to olives being stored at a temperature no higher than 27.7°C. Petra Extra Virgin Olive Oil uses olives that have been stored at 27.7°C or lower, and are pressed within 24 hours hours of being hand-harvested.
PPM = Parts Per Million
PPM is a term used in chemistry to denote a very low concentration of a solution. One gram in 1000ml is 1000ppm and one thousandth of a gram (0.001g) in 1000ml is one ppm. One thousandth of a gram is one milligram and 1000ml is one litre, so 1ppm = 1mg per litre.
Olive Oil Quality Standards
Australia has a standard for Olive Oils & Olive Pomace Oils (A 5264-2011).
In December 2013 it was reported by the Australia Olive Association that:
“Australian consumers buying imported olive oil are being duped at the checkout with up to 9 out of 10 imported olive oils failing Australian standards and being labelled incorrectly ... (of) 106 imported oils tested representing 40 different brands, 77% of oils tested failed the Australian Standard AS 5264-2011.
93% of brands tested failed the Standard for at least one product of their brand range. "
This is consistent with results found by Choice Magazine in 2010 that showed 80% of imported oils tested failed Extra Virgin standards.”
