6 things to look for on your EVOO label.

The words 'extra virgin' on a label tell you less than you think. In independent testing, a majority of imported supermarket oils labeled extra virgin failed the extra-virgin standard. Here is what actually separates the real thing, and how Olivea measures up: 1,046 mg/kg of lab-verified polyphenols, single-origin from Messinia, Greece.

  1. A published polyphenol number.

    When you're comparing olive oils, the grade on the front tells you almost nothing about what's inside. The measurable difference between oils is their polyphenol content, and most brands never publish it. Olivea is lab-verified at 1,046 mg/kg of polyphenols, and the number ships with every bottle. If a label doesn't tell you the polyphenol number, ask why.

  2. Proof it passed the standard.

    If you've ever doubted a supermarket bottle, you had good instincts. In widely cited testing by the UC Davis Olive Center, a majority of imported oils sold as extra virgin failed the standards for that grade. The industry's labeling problem is exactly why we publish independent lab results instead of asking for trust.

  3. One farm. One variety. One harvest.

    When you buy a typical bottle off the shelf, you're usually getting a blend of oils from multiple countries and harvests, nearly impossible to trace. Olivea is the opposite: single-origin Olympia olives from one organic farm in Messinia, Greece, pressed from one early harvest each year. You know exactly where your oil comes from, down to the farm.

  4. Early harvest and dark glass.

    The oil you end up pouring depends on more than origin: polyphenols fade with heat, light, and time. Olivea is picked early when polyphenol density peaks, cold-pressed within hours, held in nitrogen-sealed tanks, and bottled in UV-blocking dark glass. What reaches your kitchen is what left the press.

  5. A COA with every bottle.

    You shouldn't have to take our word for any of this. Every batch is tested by both NMR and HPLC to verify the polyphenol count, with the certificate of analysis published and shipped with every bottle. Then Iliana, our in-house olive oil sommelier, tastes each lot for freshness and balance before it earns a label. Numbers first, palate second, no exceptions.

  6. The test no label can fake.

    You don't need a lab to run your own comparison. Pour Olivea next to the bottle you have now and taste them side by side. High-polyphenol oil announces itself: greener, bolder, with a peppery finish at the back of your throat. Your kitchen is the easiest place to see what the number means.

Most commercial extra virgin olive oils carry around 100 mg/kg total polyphenols after shelf time, often blended from multiple countries and harvests with little visibility into source or test results. Polyphenol content varies by cultivar, harvest timing, processing, and storage. Olivea's number reflects current batch testing; see the COA shipped with every bottle.

Hydroxytyrosol is one of the most powerful antioxidants found in nature. Most people won't realistically consume enough olive oil to get a meaningful amount of hydroxytyrosol in their diet, so I love that Olivea has formulated an ultra-high-phenolic extra virgin olive oil to help fill that gap.

Why Olivea Ultra High Phenolic EVOO?

Most olive oils start with a single question: how do we get the most oil out of these olives? Olivea was built around a different one: how do we harvest the best oil for your health? That one shift in premise changes everything downstream — single-origin Olympia olives from one farm in Messinia, Greece, picked early at peak polyphenol density, dual-lab verified at 1,046 mg/kg polyphenols, with the COA shipped in every bottle.

Sourcing & cultivar

Single-origin Olympia olives from one farm in Messinia, Greece. Organic, no pesticides. Harvested early (when polyphenol density is highest) and milled within hours of picking. Stored in temperature-controlled nitrogen tanks. Shipped from Greece in climate-controlled containers to preserve the polyphenols through the long leg of the journey.

How to take it

One 30 ml shot daily for the full polyphenol dose. Or drizzle it over cooked food, finish a salad with it, dip bread, or use it raw on anything you'd add olive oil to. The polyphenols are stable enough to handle moderate heat but most studied at room temperature.

Lab analysis

Every batch is tested by both NMR and HPLC to triangulate the real polyphenol count. Heavy metals, microbials, and pesticide residues are screened on every lot. The COA is published and shipped with every bottle.

Very smooth with a nice taste. It has one of the highest polyphenol and hydroxytyrosol contents, which separates it from most of its competitors.

From the founder

Why we started Olivea.

After my father's sudden heart attack, I became obsessed with the daily habits I wish he'd had. Olive oil has powered the Mediterranean diet's heart health reputation for thousands of years, but only because of its polyphenols, and most oils today have very few. Olivea exists to make a polyphenol-rich olive oil you can actually take every day, with the test results to back it up.

Common questions.

How is this different from the olive oil I already buy?

Most olive oils are made to maximize yield — pressed late in harvest when olives are biggest, blended from multiple countries, and held in warehouses for months. Olivea is made for a different purpose: maximum polyphenols for your health. That changes everything — single-origin Olympia olives from one Greek farm, harvested early when polyphenol density peaks, dual-lab tested (NMR + HPLC), verified at 1,046 mg/kg of polyphenols, with the COA published in every bottle.

What is hydroxytyrosol and why does it matter?

Hydroxytyrosol is the most-studied polyphenol in olive oil and the one responsible for most of olive oil's research backing. EFSA recognized it for protection of LDL from oxidative damage at a threshold of 5 mg per day. Olivea Ultra High Phenolic EVOO is naturally rich in hydroxytyrosol because of how it's sourced, harvested, and stored.

Can I cook with it, or does heat destroy the polyphenols?

Olive polyphenols are more heat-stable than people assume. Low to medium heat (under 350°F) preserves most of the polyphenol activity. For the full dose, the most-studied use is raw: a daily shot, drizzled on finished food, or used on salads and bread.

How long does a bottle last?

If you take a 30 ml daily shot, a 500 ml bottle lasts about 16 days. Most customers use it for a mix of daily shots and drizzling, in which case one bottle typically lasts 3 to 4 weeks. Subscribing every 1, 2, or 3 months keeps you stocked at the right cadence for your routine.

Why is the polyphenol number on a bottle of olive oil so unusual?

Polyphenol testing isn't required, and most producers don't pay for it. When numbers are published, they often come from a single test method which can over- or under-state the result. Olivea uses both NMR and HPLC on every batch to triangulate the real polyphenol count, and publishes the COA with every bottle.

Where is it sourced?

Greece. Single-origin from one farm in Messinia, made from Olympia olives, harvested early when polyphenol density is highest, milled within hours of picking, then stored in temperature-controlled nitrogen tanks and shipped from Greece in climate-controlled containers.
