Who makes Kirkland Signature Extra Virgin Olive Oil (Italian 2 L / Organic 2 L)?
No reliable public evidence identifies the manufacturer of Kirkland Signature Extra Virgin Olive Oil (Italian 2 L / Organic 2 L) as of July 5, 2026.
The common claim
What most answers say — and what the evidence supports
Top-ranking answers are contradictory and unevidenced: most content mills 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.
Evidence & sources
Costco does not disclose its suppliers, and no tier 1–5 source names the maker of this product. Below is the documented search — every database and record we checked, and what each one returned.
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 deterministic 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 content-mill 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.
Manufacturer history
The change log is the product. Attributions go stale — most sites never notice when a supplier switches. We date every change, keep the old source, and log it.
| Period | Manufacturer | What the record says | Source |
|---|---|---|---|
| Present | Not established | Current attribution — unknown. See the evidence and fact sentence above. | Evidence ↑ |
| … → April 2015 | Certified Origins Italia | Attributed (indirect — one of several import resources, never established as sole bottler): trade press reported Certified Origins Italia was "one of the resources employed by Costco for its EVOO imports" when the FDA detained and refused shipments from the producer in 2013. Costco dropped its Italian exporters entirely in April 2015. | Olive Oil Times ↗ |
| April 2015 → August 2016 | Unnamed Greek suppliers | Attributed (unverified) at the country level only: Costco corporate switched the 2 L Kirkland Signature EVOO — "the main sales driver for the past few years" — to 100% Greek oil in April 2015 and back to Italian oil in August 2016, per Costco buyer Chad Sokol on record with Olive Oil Times. The Greek producers, and the Italian suppliers Costco returned to, were never publicly named. | Olive Oil Times ↗ |
