The common claim vs. the evidence

What’s commonly claimed, and what the evidence supports

Top-ranking answers are contradictory and unevidenced: most roundup articles say only that the oil comes from Puglia, Italy without naming a company; at least one asserts Deoleo bottles it (no source given); and the one on-record supplier fact — Certified Origins Italia as "one of the resources" for Costco's EVOO imports — dates to 2013, before Costco's documented 2015–2016 supplier-country switches, so no tier 1–5 evidence identifies the current bottler.

Costco does not disclose its suppliers, and no tier 1–5 source names the maker of this product. Below are the databases and records we checked, and what each one returned.

What we checked: 8 databases & records, as of July 5, 2026

FDA recalls / enforcement reports ("Kirkland" + olive oil sweep) July 5, 2026

No Kirkland Signature olive oil recall on record; no co-packer or bottler named in any recall or enforcement report.

CourtListener + RECAP (query: "Kirkland Signature" "olive oil") July 5, 2026

3 published opinions, all unrelated to olive oil sourcing (Kurtz v. Kimberly-Clark and Belfiore v. Procter & Gamble flushable-wipes cases; one TTAB trademark opposition that merely lists olive oil in a goods description). No litigation naming a Kirkland olive oil supplier.

US plant-code routes (USDA FSIS establishment / FDA IMS dairy / NDC / TTB / API) July 5, 2026

Not applicable — olive oil carries no US plant or registration code, and the product is bottled abroad (labels state it is packaged in Italy).

UC Davis Olive Center olive oil quality reports (July 2010 report2010finalthree.pdf; 2011 follow-up) July 5, 2026

The July 2010 study tested "Kirkland Organic" samples from three California cities; the report identifies samples by brand name only and names no supplier, bottler, or importer for any brand tested.

Olive Oil Times archive (2016 Costco buyer coverage, via Wayback Machine) July 5, 2026

The only producer ever named in trade press is Certified Origins Italia, described (2016-08-23 article) as "one of the resources employed by Costco for its EVOO imports" in the context of 2013 FDA import detentions — one of several suppliers, and pre-dating Costco's documented April 2015 switch to unnamed Greek suppliers and August 2016 switch back to unnamed Italian suppliers. No current bottler named; recorded under history.

ImportYeti (US customs bills of lading, Costco Wholesale company page) July 5, 2026

Page inaccessible (HTTP 403) at research time, so no bill-of-lading match could be retrieved; per the SPEC tier 5 caveat, Costco masks many shipments via freight forwarders, so absence would prove nothing regardless.

Costco.com product listings + Costco Connection / food-press label coverage July 5, 2026

Labels disclose origin only: "Product of Italy" on the Italian 2 L, and a multi-country Mediterranean organic blend packaged in Italy on the Organic 2 L, plus a Bureau Veritas origin-traceability seal — no bottler or producer named anywhere.

Google/Bing top-answer sweep ("who makes kirkland olive oil" and variants) July 5, 2026

Contradictory roundup-article answers: most name only a region (Puglia — Bari and Barletta-Andria-Trani provinces) with no company; at least one (Chef's Resource) asserts Deoleo bottles the Italian EVOO with no evidence cited; none cites a tier 1–5 source.

The Greek producers, and the Italian suppliers Costco returned to, were never publicly named.	Olive Oil Times ↗

Frequently asked

Who makes Kirkland Signature extra virgin olive oil?

No reliable public evidence identifies the current bottler. Costco's labels say only "Product of Italy" with a Bureau Veritas traceability seal, and Costco buyers describe a multi-supplier program run from corporate. Olive Oil Times named Certified Origins Italia in 2016 as one of Costco's EVOO import resources as of 2013, but Costco dropped its Italian exporters for Greek suppliers in April 2015 and switched back to unnamed Italian suppliers in August 2016, so any pre-2015 attribution is stale, and no source since has named the bottler.

Is Kirkland olive oil real extra virgin olive oil?

The best independent evidence supports the label. In the UC Davis Olive Center's July 2010 study — in which 69 percent of imported "extra virgin" samples failed international sensory standards — Kirkland Organic passed, and contemporaneous coverage reported it was the only imported brand whose samples passed at all three sampling locations. Recent bottles also carry Bureau Veritas origin-traceability certification, per food-press coverage. That evidence speaks to quality and origin, not to who bottles it.

Where does Kirkland Signature olive oil come from, and is the organic one different?

The core 2 L extra virgin is labeled "Product of Italy"; food-press coverage places it in Puglia (Bari and Barletta-Andria-Trani provinces, Coratina and Cima di Bitonto olives), though Costco itself discloses only the country. The Organic 2 L is different: it is a multi-country Mediterranean blend packaged in Italy, with labels listing olives from countries such as Italy, Portugal, Greece, Spain, and Tunisia depending on the lot. Neither bottling names its producer. Costco also sells separate Spanish, California, and Toscano PGI versions as distinct products.

Did Kirkland olive oil ever change suppliers?

Yes, at the country level, on the record: per Costco buyer Chad Sokol in Olive Oil Times, Costco dropped its Italian exporters entirely in April 2015, sold 100% Greek oil in the 2 L bottle for about 14 months, then returned to Italian oil in August 2016 because "it was what members wanted." The specific producers on either side of those switches were never publicly named.
