Yes, always! We don’t believe that anyone should have to consume anything but ‘extra virgin’ olive oil. It is simply the best quality olive oil available, offering the greatest taste and nutritional benefits. Next time you buy olive oil, be sure to look for the words ‘extra virgin’ on the label.

Freshness is the key to quality olive oil, and with that in mind, we’ve developed the perfect packaging for our larger volume (2L and 15L) EVOO products. Our 'bag in box' is very similar to cask wine, helping to protect our oil from its two greatest enemies: light and oxygen. This not only keeps the oil fresher for longer, but also saves on unnecessary freight costs and the emissions associated with shipping heavy packaging.

Unfortunately, our warehouse shop is not open on weekends at this stage.

The three biggest enemies that affect the freshness of extra virgin olive oil are heat, light and oxygen.

To prevent unnecessary degradation of your olive oil, store it in a cool, dry place with minimal light. Always make sure you store your oil with the lid tightly on, or purchase our bag-in-box packaging to ensure your oil stays fresh till the very last drop.

You can store them in the fridge if you'd like, but as our olives are a fermented product, they will last unrefrigerated as long as they're stored well. We recommend you store our olives out of the sun, below 30 degrees, and ensure that you always have a slight covering of olive oil across the surface of the brine. The surface of the brine can be susceptible to growing a harmless layer of yeast and possibly mould when exposed to air, but a layer of olive oil on top of your brine will prevent this. If you do see some yeast growth, simply remove it using a spoon.

We hold 3-4 markets a year at our Sunshine West warehouse. To see when the next market is, click here.

We sure do! We sell our extra virgin olive oil in both bottles and in bulk. We also sell our olive oil by the litre in our warehouse shop, so you can come in with your own bottles and fill them directly from our tanks.

Buying your oil in bulk is not only a great way to save money, but it saves unnecessary packaging too!
