Who makes Kirkland Signature Organic Raw Kombucha, Ginger Lemonade, 16 fl oz, 8-count?
No reliable public evidence identifies the manufacturer of Kirkland Signature Organic Raw Kombucha, Ginger Lemonade, 16 fl oz, 8-count as of August 3, 2026.
The common claim
What most answers say — and what the evidence supports
Top-ranking answers most often guess GT's Living Foods (formerly GT's Kombucha) as the brewer of Kirkland Signature Organic Raw Kombucha, pointing to the similar bottle shape and to GT's own 'Gingerade' versus Kirkland's 'Ginger Lemonade' - but this is unsourced speculation. Others name Brew Dr., KeVita, Health-Ade, or Wild Tonic. Costco discloses no brewer on the bottle or box, and no tier 1-5 evidence supports any of these names.
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.
openFDA food enforcement (recall) API July 6, 2026

SEC EDGAR full-text search (2001-present) July 6, 2026

Costco.com product-detail mfName field (via Wayback; costco.com blocks live fetch) July 6, 2026
The only archived Costco kombucha page (Costco Business Delivery, 2022-11-04, .product.100340647.html) predates and does not contain the 'mfName' catalog field, and no snapshot of a current /p/-/ page exists, so the field-lookup route is unavailable. Costco discloses no brewer on-pack or online - notable, since Kirkland espresso and some other items name their maker.
ImportYeti (US customs bills of lading) July 6, 2026
No Costco kombucha supplier signal retrievable; route is structurally weak - raw kombucha is refrigerated and domestically brewed, not import-shipped, and Costco masks shipments via freight forwarders (tier 5 caveat).
News / community rumor sweep (Reddit r/Costco, everythingkombucha.com, rvandplaya.com, inspiredplum.com, Food Republic) July 6, 2026
Tier-6 guesses only, and they conflict: GT's Living Foods is the most-repeated candidate (its bottles, and its own 'Gingerade', resemble the Kirkland Ginger Lemonade), with Brew Dr., KeVita Master Brew, Health-Ade, and Wild Tonic also named. Every source frames it as speculation ('one big guessing game'); no evidence backs any name.
