Who makes Kirkland Signature Organic Greek Nonfat Yogurt, Plain (48 oz / 3 lb tub)?
As of July 5, 2026, evidence points to Ehrmann Commonwealth Dairy (acquired by Lactalis Group, 2019) as the manufacturer of Kirkland Signature Organic Greek Nonfat Yogurt, Plain (48 oz / 3 lb tub), but no tier 1–3 source names the link directly.
The common claim
What most answers say — and what the evidence supports
Top answers — a cluster of Static Media articles all citing one 2017 business book — name Ehrmann Commonwealth Dairy, which tier-4 evidence supports but only indirectly for today's tub (the claim pre-dates Lactalis's 2019 purchase of Ehrmann's US plants), while a Costco fan blog's rival Skotidakis claim rests on a package plant code the blog never actually shows and remains unverified.
Evidence & sources
Every source is graded on the six-tier rubric and archived, so the citation holds even if the original moves or paywalls. The tier badge grades the source; the status grades our confidence in the maker.
Tier 6
2017 book reported to state Ehrmann sells Greek yogurt to Costco under the Kirkland Signature label — graded tier 6, not 4, because the load-bearing quote circulates only via Static Media outlets and was not verified against the book text (upgrade path: read the book; if the quote checks out this becomes tier 4). The claim also pre-dates Ehrmann's 2019 exit from US yogurt.
Tier 4
Company's own release: 'Commonwealth will initially distribute quarts of its organic plain yogurt with Costco in the San Francisco region,' then expand — matches the organic plain Greek nonfat SKU exactly but never says 'Kirkland,' so it is indirect.
Tier 4
Lactalis release: Ehrmann Commonwealth Dairy's Brattleboro VT and Casa Grande AZ plants and 'strong private label business' passed to Lactalis Group as of July 2019 — no Costco/Kirkland mention; establishes who would hold any such contract today.
Tier 6
Secondary press aggregation (unverified): attributes Kirkland Signature Organic Greek Nonfat Yogurt to Ehrmann solely via Cohan's 2017 book and the 2014 press release, and notes Ehrmann's 2019 sale to Lactalis; adds no independent evidence.
