Graza Olive Oil Polyphenol Content: What We Know

Graza Olive Oil Polyphenol Content: What We Know

Graza does not publish batch-specific polyphenol data for its Drizzle or Sizzle olive oils. One independent test (Olivea, 2025) measured Graza at 312 mg/kg total polyphenols, above the 250 mg/kg EFSA health claim threshold and below the 500–1,000+ mg/kg range of brands that market specifically on polyphenol concentration. Graza uses "High Polyphenol" on Amazon listings for both Drizzle and Sizzle without published lab data behind it. Polyphenol content is what drives the health effects research has documented for extra virgin olive oil, particularly LDL oxidation protection and anti-inflammatory activity, so for a health-focused buyer the absence of published numbers is the gap that matters. On accessibility, sourcing, and everyday usability, Graza performs well.

Key Facts: Graza Olive Oil Polyphenols

  • Graza's published polyphenol data: None. Graza does not publish batch-specific polyphenol mg/kg on its labels, website, or product listings
  • Independent test result: 312 mg/kg total polyphenols (Olivea independent lab test, 2025, single batch tested)
  • EFSA health claim threshold: 250 mg/kg. Graza's tested batch exceeds it at roughly 1.25x
  • Graza's marketing claim: "High Polyphenol," used on Amazon listings for both Drizzle and Sizzle without published verification
  • Olive variety: 100% Picual olives from Jaén, Andalusia, Spain. Single-origin, single-varietal
  • Harvest date: ✅ Published on bottles (lot code lookup), a genuine positive
  • Packaging: BPA-free opaque plastic squeeze bottles. Convenient, though plastic allows oxygen permeability over time
  • Comparison: Brands marketing on polyphenol concentration test at 500–1,000+ mg/kg, roughly 1.6x to 3x+ Graza's tested level

What Is Graza's Polyphenol Content?

Graza does not publish polyphenol content on its labels or website. The brand describes its Picual olives as naturally high in polyphenols and uses "High Polyphenol" in its Amazon product titles for both Drizzle and Sizzle, but provides no mg/kg number behind the claim.

The only independent test result publicly available comes from Olivea, a competitor brand, which reported Graza at 312 mg/kg total polyphenols. This is a single-batch test from one source rather than a comprehensive analysis across multiple batches or harvest years. Polyphenol content varies by harvest date, pressing conditions, storage time, and lot, so a single test provides a data point rather than a definitive answer.

For context, 312 mg/kg places Graza above the EFSA health claim threshold of 250 mg/kg and below the brands that build their positioning around concentration. The polyphenols in olive oil that drive health benefits, including oleocanthal, hydroxytyrosol, and oleuropein, are present at higher concentrations in oils testing at 500+ mg/kg.

How Does Graza Compare to Other Olive Oil Brands for Polyphenols?

Brand Polyphenols (mg/kg) Data Published by Brand? Harvest Date Origin Price/oz
The Governor (Greece) 1,377 (NMR, 2025/26) ✅ Yes ✅ Yes Corfu, Greece ~$3.00
Cobram Estate Robust 500–900 ✅ Yes (range published) ✅ Yes Australia ~$1.00
Papa Vince (Sicily) 515 (HPLC, Feb 2025) ✅ Yes (exact mg/kg) ✅ Yes Santa Ninfa, Sicily ~$1.80
Hoji Blanca (Spain) 306 ± 21 (HPLC, Nov 2025) ✅ Yes (batch-specific) ✅ Yes Andalusia, Spain $1.47/pkt
Graza Drizzle (Spain) 312 (Olivea test, single batch) ❌ No ✅ Yes (lot code) Jaén, Spain ~$0.59
Terra Delyssa (Tunisia) 200+ ⚠️ General claim only ✅ Yes Tunisia ~$0.50
Kirkland Organic (Costco) 200–300 (est.) ❌ No ✅ Yes Blend ~$0.36
Bertolli ~182 (est.) ❌ No ❌ No Multi-country ~$0.40

Hoji and Graza test at comparable concentrations. The difference is verification: Hoji's 306 ± 21 mg/kg comes from a dated, batch-specific third-party report (Indlab, ENAC-accredited, COI/T.20/Doc. nº 29 Rev. 2, November 2025), while Graza's 312 mg/kg comes from a single independent test run by a competitor rather than from Graza. Multiple-batch verification would give a more reliable picture for both. For the complete 12-brand ranking, see healthiest olive oil brands ranked. Disclosure: Hoji Real publishes this article. All brands are scored with the same criteria.

Does Graza Publish Lab-Tested Polyphenol Data?

No. As of August 2026, Graza does not publish polyphenol content (mg/kg) on its product labels, website, or retail listings. The brand publishes acidity (below 0.4%), confirms the oil is cold-extracted and unfiltered, and provides harvest dates via lot code lookup, all positive transparency markers. It does not provide the polyphenol data a health-focused buyer would use to check the oil against the EFSA health claim threshold.

Graza uses the phrase "High Polyphenol" in its Amazon product titles, which sets an expectation of verified data. For comparison, Papa Vince publishes exact HPLC-verified polyphenol numbers (515 mg/kg as of February 2025), Cobram Estate publishes a polyphenol range for its Robust line (500–900 mg/kg), and Hoji publishes a batch-specific figure with the report date and testing method. Publishing polyphenol data has become common practice in the premium EVOO space.

Is Graza's "High Polyphenol" Claim Accurate?

Partly, with context.

Picual olives from Jaén, Spain, are genuinely among the highest-polyphenol olive varieties. Research consistently shows Picual producing EVOOs at 200–800+ mg/kg depending on harvest timing, growing conditions, and pressing methods. Graza's choice of variety and region gives it a strong foundation.

The independent test of 312 mg/kg exceeds the EFSA threshold of 250 mg/kg, so the tested batch qualifies as an olive oil that can carry the blood lipid protection claim. In industry usage, though, "high polyphenol" typically describes oils at 500+ mg/kg, and the brands using that term with published data behind it (Cobram Estate Robust at 500–900, Papa Vince at 515, The Governor at 1,377) sit well above the tested Graza figure.

So on the available evidence, the tested batch reads as moderate on the industry's own scale rather than high, and there's no published data from Graza to check that against.

Is Graza a Good Olive Oil?

Yes, for what it's designed to be. Graza's strengths are real and significant:

  • Single-origin Picual from Jaén, Spain, genuine terroir and traceable sourcing from one of the world's best olive oil regions
  • Harvest dates published via lot code lookup, a transparency marker most grocery store brands lack
  • Accessible pricing at ~$0.59/oz, which makes quality EVOO affordable for everyday use
  • Genuinely extra virgin, cold-extracted, unfiltered, unrefined, low acidity (below 0.4%)
  • Functional packaging, since the squeeze bottle is a real usability improvement over traditional glass
  • Available everywhere, including Costco, Whole Foods, Amazon, and 11,000+ stores nationwide

Graza is one of the best things to happen to olive oil in America. The brand has moved millions of people from refined seed oils to real extra virgin olive oil, and that shift alone has meaningful health value. Andrew Benin and Allen Dushi built something genuinely impressive since founding Graza in January 2022.

The limitation is narrow and specific. If your primary reason for choosing an olive oil is polyphenol content, for cardiovascular protection, anti-inflammatory benefits, or brain health, Graza doesn't publish the data you'd need to evaluate it, and the single independent test available puts the tested batch in the moderate range. For culinary quality, accessibility, and everyday cooking, Graza performs well.

Does Graza's Plastic Packaging Affect Polyphenol Content?

Potentially, though the effect is debated. Graza uses opaque BPA-free plastic squeeze bottles, which protect against light degradation, a genuine positive. Plastic is more oxygen-permeable than glass or tin, though, and oxygen exposure accelerates polyphenol degradation. Research has documented substantial phenolic loss during storage even under good conditions (Mulinacci et al., Journal of Agricultural and Food Chemistry, 2013), and oxygen-permeable packaging may accelerate that timeline.

Graza addresses this partly by pressing and bottling in the same season and printing harvest dates. If you buy a fresh bottle and use it within a few months, the packaging difference is likely minimal. If the bottle has been on a shelf for 6–12 months, degradation may be more significant than it would be in dark glass or tin.

What Should You Buy If Polyphenol Content Is Your Priority?

If you're choosing olive oil primarily for health benefits, whether that's cholesterol management, anti-inflammatory support, or brain health, prioritize brands that publish verified polyphenol data. The clinical research showing olive oil health benefits used oils with specific, verified polyphenol concentrations rather than unverified marketing claims.

Look for these three things:

  1. Published polyphenol mg/kg from HPLC, NMR, or equivalent lab testing, ideally batch-specific and dated
  2. Harvest date within 12 months, since polyphenols degrade over time regardless of packaging
  3. A concentration inside the tested evidence band. The EFSA threshold of 250 mg/kg is a regulatory floor, and EUROLIVE, the trial the EU claim largely rests on, used oils up to 366 mg/kg. Above roughly 400 mg/kg, claims of proportionally greater benefit run ahead of the trial evidence

Want verified polyphenol data with every batch?
Hoji publishes batch-specific lab results for its single-origin Hojiblanca EVOO from Andalusia: 306 ± 21 mg/kg total phenolic compounds, zero sensory defects, November 2025 harvest. Every packet is sealed against air and light until you open it, so the last one performs like the first.

Frequently Asked Questions

What is the polyphenol content of Graza olive oil?

Graza does not publish polyphenol content. The only publicly available data comes from an independent test by Olivea, a competitor, which measured Graza at 312 mg/kg total polyphenols. This exceeds the 250 mg/kg EFSA health claim threshold and sits below brands like Cobram Estate Robust (500–900 mg/kg), Papa Vince (515 mg/kg HPLC verified), or The Governor (1,377 mg/kg NMR verified).

Is Graza really "high polyphenol" olive oil?

Graza uses "High Polyphenol" in its Amazon product titles but does not publish lab data to support it. The one independent test at 312 mg/kg places Graza above the EFSA threshold and below what the EVOO industry typically calls high polyphenol (500+ mg/kg). Graza's Picual olives from Jaén are a genuinely high-polyphenol variety, though final content depends on harvest timing, pressing, storage, and packaging, which only published lab data can confirm.

How does Graza compare to Cobram Estate for polyphenols?

Cobram Estate Robust publishes polyphenol data in the 500–900 mg/kg range depending on batch and harvest year. Graza's single independent test showed 312 mg/kg. At the midpoint, Cobram Estate delivers roughly twice the polyphenol content at a higher price (~$1.00/oz vs ~$0.59/oz), and publishes the figure itself.

Does Graza publish a harvest date?

Yes, and this is one of Graza's genuine strengths. Harvest dates are available via lot code lookup on their website, and Graza presses and bottles in the same season. This practice puts Graza ahead of most grocery store brands, which provide only "best by" dates.

Is Graza olive oil good quality?

Yes. Graza is genuine extra virgin olive oil, single-origin Picual from Jaén, Spain, cold-extracted, unfiltered, with low acidity below 0.4%. For everyday cooking and finishing it's a significant upgrade over grocery store brands like Bertolli, Filippo Berio, or Pompeian. The limitation is specific to health optimization: no published polyphenol data, and one independent test showing a moderate level.

Why doesn't Graza publish polyphenol content?

Graza hasn't stated a reason publicly. The brand's messaging centers on accessibility, culinary enjoyment, and everyday use rather than health optimization, and polyphenol figures aren't standard practice across the category the way harvest dates increasingly are. Whatever the reasoning, the effect for a health-focused buyer is the same: no published number to evaluate.
