This topic is very dear to us! Before co-founding Wonder Valley, Alison Carroll’s previous role was overseeing the certification of olive oil as ‘extra virgin grade’ for the state of California and acting as an educator and industry advocate. Whether you are buying Wonder Valley or another brand’s olive oil, here are a few tips to ensure you are buying true extra virgin olive oil.
Make sure there’s a harvest date on the bottle and not just an expiration date: this is a fruit juice that doesn’t age well. You must have transparency on when it was pressed to ensure freshness.
Single-origin: Scrutinize the label and see where it is made. Ideally, it should come from a single location or region to ensure quality control. This is a common practice for imported oils: to claim one country on the front, and then the back label reveals the product of x,y, and z countries. A blended oil like this will be challenging to know how fresh it is if it’s true extra virgin grade, or what the shelf life is.
Buy direct or from a reliable source. It’s always great to buy directly from the olive oil producer, but a knowledgeable retailer can talk you through the flavor profile and answer questions.
Buy oil in a glass or aluminum vessel. As plastic gets exposed to light and heat, it can potentially break down into microplastics. Because glass is an impermeable material, it does not react with olive oil, making it a safe storage vessel at any temperature, condition, or period of time. Glass and aluminum, unlike plastic, can be recycled over and over, making it a better material choice for sustainability, as well.
Taste it! If you have an opportunity to taste an olive oil, we encourage you to try it by itself as a shot or by the tablespoon. There are a number of defects that can happen to olive oil that disqualify it as extra virgin grade, each with its own distinct flavor and aroma. But you do not have to be a trained taster to detect these. An extra virgin olive oil will taste like natural things: grass, nuts, fruits, herbs. You can wax poetry about the description of an olive oil! A non-extra virgin grade oil will have notes that taste off and unnatural, some common ones include paraffin wax, brined olives, and spoiled peanut butter. Trust your instincts and get tasting!
