Behind the Scenes: Olive Harvest 2025

It’s harvest time at Great Southern Groves, and the grove is buzzing—both with machinery and energy. The mornings are very icy in the Great Southern and the crew is layered up against the cold. Rain, frost or shine, harvest waits for no one!

We’re currently working long days to bring in the fruit at its optimal ripeness. Timing is everything. Once the olives are picked, they head straight to the press – processed within 24 hours to ensure we produce the freshest flavour and highest quality oil. The whole fruit is crushed and goes through a malaxer (a large mixing machine). The resulting paste (looks like tapenade) is put through 2 large centrifuges. The first spins off the liquid (oil and water) from the solids (pits, skin, flesh). The second then separates the oil from the water. This means the processing shed is REALLY noisy. It is like having 2 jet engines going the whole time. Ear protection is a must! The end product, our premium extra virgin olive oil.

We’re thrilled with the quality of this year’s harvest and can’t wait for you to taste it. Our fresh, new season extra virgin olive oil is now available in our 3L tins—with our 15L boxes coming very soon. Keep an eye out—it’s worth the wait!

2025 PRIMA EVOO has arrived

The freshest olive oil of the season, straight from the press and into your hands.

PRIMA extra virgin olive oil or Olio Nuovo (meaning new oil), is the very first press of the harvest – vibrant, cloudy and full of flavour.

Unlike most extra virgin olive oils that are settles and filtered, this one is bottled immediately after pressing, capturing the raw, robust character of the olives.

Our 2025 PRIMA has a sweet, fruity aroma with vibrant grassy and herbal notes, finishing with that signature peppery kick. It’s bursting with polyphenols—those powerful antioxidants that make extra virgin olive oil so good for you.

Each 700ml bottle is hand filled, labelled and numbered—and once this limited release is gone, it’s gone until next year.

Drizzle it over soups, swirl it through salads, whip up a pesto that sings—or take a walk on the wild side and pour it over vanilla ice cream (trust us, it’s magic).

Best enjoyed within 4–6 weeks of opening for peak freshness.

Why you should be washing your olive oil bottle.

It is important that you wash your refillable olive oil bottles regularly. We like to remind our customers to do this every 3 months.

When you bottle has completely run out of olive oil, wash it with with hot soapy water. If you have a bottle brush, even better.

Make sure your bottle is completely dry before refilling.

Why wash your bottle regularly? Even when your bottle is completely empty, there will always be a little oil left. Washing your bottle means that you are not adding fresh olive oil to old olive oil. Keeping your oil tasty and lasting longer.

More steps towards sustainability

At Great Southern Groves, we’ve always believed in creating not only exceptional Australian olive oil but also a better future for the environment. Over the last 2-3 years, we’ve taken meaningful steps towards becoming a more sustainable business, driven by both consumer demand and our own commitment to protect the planet we all share.

Why Sustainability Matters

Our industry, especially olive oil production, is severely impacted by climate change—high temperatures and low rainfall affect the quality and quantity of our olives. That’s why it’s essential for us to adopt sustainable farming practices and move towards more eco-friendly packaging.

What We’ve Done So Far

We’re excited to share the steps we’ve taken towards sustainability:

Bulk Packaging Change: We’ve replaced plastic cubes with eco-friendly bag-in-the-box packaging for our bulk olive oil. This shift has helped us eliminate a substantial amount of plastic from our business. Our new packaging is not only more sustainable but also practical—each box comes with its own tap, is easier to store on shelves, and can be conveniently posted or sent anywhere across Australia. Plus, it keeps the oil fresher for longer!

More Eco-Friendly Tins: We’ve replaced our 3L tins with laminated paper labels with pre-printed tins. This simple change has helped us eliminate thousands of meters of non-recyclable backing material that would have ended up in landfill.

Refill, Reuse, Repeat: We encourage our customers to refill bottles from our 15L boxes or 3L tins. To make this even more beautiful and functional, we sourced a modern amphora-style bottle made of high-quality glass. Paired with a sleek chrome pourer, these bottles are perfect for refilling and display on your kitchen bench.

The Art Series: We took our commitment to sustainability a step further by launching the Art Series bottle. This series features artworks by talented Australian artists. Just before Christmas, we released the second bottle in the series by Western Australian artist Emma Blyth. Fly High showcases the White-Cheeked Honeyeater landing on a Banksia.

Thank You for Your Support

We would like to extend a heartfelt thank you to all of our wonderful customers who have embraced our sustainable and recyclable packaging. Your support helps us move forward in our journey to make olive oil that not only tastes great but also contributes to a healthier planet.

We remain committed to reducing our environmental impact and appreciate your continued support in helping us reach our sustainability goals. While these steps may seem small, we truly believe that, together, we can make a lasting difference.

How Olive Oil is Judged: From Chemistry to Taste

For anyone passionate about high-quality olive oil, knowing how it is judged can deepen your appreciation for premium quality olive oil. Australia olive oil competitions uphold strict standards by combining scientific analysis with expert tasting. Here’s are the key steps in assessing an olive oil’s quality and what these evaluations mean for both consumers and producers.

Step 1: Chemical Testing

Chemical analysis begins the judging, focusing on four main indicators:

% Free Fatty Acid (FFA): A low FFA suggests good grove and processing practices. For an olive oil to be called ‘Extra Virgin’, is needs to have a FFA% under 0.8%.

Peroxide Value (PV): This measures oxidation levels, giving insights into the oil’s freshness and storage conditions. The maximum peroxide value for an Extra Virgin Olive Oil is 20 with high quality Extra Virgin Olive Oil having a peroxide value below 12.

UV Absorbance: This test helps assess the oil’s preservation state, indicating whether it has started to degrade.

Polyphenol Content: Polyphenols affect both taste and health benefits. High-polyphenol oils offer robust flavours, while lower levels result in milder, delicate oils, categorized as ‘R’ (robust), ‘M’ (medium), or ‘D’ (delicate).

These chemical measures provide a reliable foundation to gauge quality before tasting.

Step 2: Sensory Assessment

Australian olive oil competitions use the Australian Olive Association’s 100-point scoring system. This includes an assessment of the oil’s freshness, aroma, and flavour complexity, balance, and aftertaste.

AROMA being good fruit intensity, complexity & absence of faults.

PALATE including good fruit intensity, the bitterness & pungency, balance and absence of faults

COMPLEXITY balance, including bitterness & pungency.

This judging process gives consumers confidence, knowing the oil’s quality is confirmed scientifically and through expert taste, helping them find the ideal oil for their culinary needs.

Great Southern Groves – Tuscan Style, Extra Virgin Olive Oil and PRIMA Extra Virgin Olive Oil have both won SILVER at the recent, 2024 – WA Olive Awards.

A new Art Series bottle coming in 2024

We’re excited to reveal the latest painting for our Art Series refillable bottles.
‘Fly High’ a stunning commissioned piece by WA artist Emma Blyth.

Following the success of Silvereye in the Grove, Emma has once again captured the essence of our beautiful Western Australian birds, this time a white-cheeked honeyeater in the banksias.

We also work with graphic designer Greenhouse Studio to convert the painting to a file suitable for glass printing… Mosman Glass printers, where the piece is permanently painted/ printed onto our unique bottles from Plasdene Glass-Pak.

These bottles are filled with award winning Australian olive oil —perfect for unique, thoughtful gifts! A perfect way to blend art, sustainability, and practical gifting.

2024 Olive Oil Prices

Have you seen the news? Or heard about the price of olive oil increasing worldwide, including Australia?

This is for a number of reasons…

Australia is an olive oil loving nation and we consume more olive oil than we can produce each year. This shortfall is then covered by imported olive oils, mainly from Spain, Italy and Greece. With Spain being one of the biggest producers.

In recent growing seasons, Europe, particularly Spain, has experienced a significant decline in olive oil production due to drought and other environmental factors. This decrease has driven up olive oil prices in Europe, which has also impacted prices globally, including in Australia.

In addition to this, many countries that traditionally purchase their olive oil from Europe are now looking to other markets, such as Australia to fulfill their demand.

Locally, olive oil production has been mixed. Many of our olive producers have also experienced challenges with weather and pests. This all unfortunately leads to prices being pushed higher and higher.

The good news… Great Southern Groves had a pretty good crop in 2024 and we hope to have enough olive oil to see our customers through the whole year. We have also created a 3L tin subscription for our customers to overcome two issues. One, a price saving for our customers and two, the subscription means we can plan ahead and make sure we have enough olive oil for our loyal customers.

Subscriptions can be set for the amount of olive oil you use… one month, two months, even every six months.

We hope that you keep enjoying your Great Southern Groves, Extra Virgin Olive Oil in all of your cooking and baking.

Are you storing your olive oil correctly?

Did you know that Extra Virgin Olive Oil is a fruit juice! As olives grow on trees, they are classified as a fruit. So technically the liquid you squeeze out of them is a juice.

Unlike other fruit juices, olive oil is shelf stable and doesn’t need to be kept in the fridge. However, like most fruit juices, it doesn’t improve with age. The Best Before date on our Extra Virgin Olive Oil is 2 years from harvest date, the closer you consume it to pressing, the healthier it is for you.

Oxygen, heat and light are the three main enemies of olive oil. So, to combat these…

Keep the lid on tight.

Keep it away from any sources of heat.

Keep it in the dark.

What about keeping a bottle on the kitchen bench? Two things to consider are the type of bottle and where you keep it. 

A thick, dark glass or ceramic, 500ml bottle or smaller is perfect for keeping your oil fresh.  Our decorative bottles are designed for this purpose. We chose them as they have particularly thick and dark glass, serving as a protection for the olive oil. If you are keeping the bottle on your kitchen bench, the location is also important.  Near the stove is handy however, the heat can cause your olive oil to deteriorate quickly both in flavour and nutritional value.  You can certainly store the bottle stove-side, just be aware of the length of time it takes you to empty the bottle. If you use only a small amount over a week, then consider only filling the bottle each week to the amount you use. Also remember to wash out your bottle each time you purchase a new 3L tin or every two to three months.

Buying olive oil in bulk like the 3L tin and 15L box? Decant the oil into your gorgeous bottle on the kitchen bench and then pop the bulk container back into the cupboard, in the dark. Please make sure the lid is replaced tightly back on your tin.  Ideally you want to use the olive oil in your 3L tin within 6 months of opening. As for our new 15L Bag in Box… these are perfect for storing large quantities of olive oil for longer periods of time as they eliminate light and oxygen exposure.

Our recyclable dukkah pouches

If you have been following our stories on social media this year, you will see we are making a concerted effort to become a more sustainable business.

One way to do this was to review all of our packaging. We have been working closely with one of our packaging suppliers, Myerton Packaging, to make our packaging more sustainable or recyclable.

Our old dukkah pouches were plastic lined, paper pouches with a label applied. Due to multiple materials, these pouches were not recyclable. The amount of waste created by the labels is also alarming. All of the backing from the labels also goes into landfill.

Myerton Packaging were supplying new Roll n Recycle pouches to a number of their other clients and we thought our dukkah would look amazing in them too.

These pouches are made with a single material and are a special ‘roll and recycle’ design. When your delicious dukkah has finished, you roll the pouch up, affix the sticker from the back of the pack and then place it in your kerbside recycling bin.

We are super excited with the sustainably of these new pouches and also the gorgeous new package design.
