Who makes Kirkland Signature 100% Colombian Coffee (Supremo Bean), Dark Roast (3 lbs)?
As of September 21, 2026, evidence points to JBR, Inc. as the manufacturer of Kirkland Signature 100% Colombian Coffee (Supremo Bean), Dark Roast (3 lbs), but no tier 1–3 source names the link directly.
The common claim
What’s commonly claimed, and what the evidence supports
Food media and shopper guides name Rogers Family Company as the maker of Kirkland's Colombian Supremo, and the documentary evidence backs that up: Costco's own Costco Connection profile identifies Rogers Family Company as the roaster behind Kirkland Signature's origin-specific coffee program, Coffee Review lists this exact Colombian Supremo's roast location as Lincoln, California — Rogers Family Company's headquarters — and The Daily Meal attributes the Colombian Supremo to Rogers Family Co. The bag itself names no roaster, so the attribution is evidence-based rather than label-confirmed; it points to Rogers Family Company, whose retail brand is San Francisco Bay Coffee.
Evidence & sources
Each source is graded on the six-tier evidence rubric, where tier 1 is strongest. Sources are archived, so a citation still works if the original page moves or goes behind a paywall.
Tier 4
Costco's own magazine names Rogers Family Company (HQ Lincoln, CA; retail brand San Francisco Bay Coffee) as its coffee roaster and quotes Costco merchandising manager Jay Tilley: 'Long before the words "fair trade" or "sustainable" were industry concerns, we were [practicing] it with the Rogers Family Company through some of our Kirkland Signature line of coffees.' The profile box lists 'Items at Costco: Kirkland Signature origin specific program, which includes Costa Rica, Guatemala, Rwanda and Sumatra, and other offerings' — Rogers roasts Kirkland's origin coffees, but this page does not name the Colombian Supremo specifically, so the attribution is indirect (probable, not confirmed).
Tier 6
SKU-specific corroboration: the review of 'Colombian Supremo by Kirkland Signature (Costco)' lists 'Roaster Location: Lincoln, California' (Coffee Origin: Concordia, Colombia) — Lincoln, CA is Rogers Family Company's headquarters and roasting site, tying this exact bag to Rogers. Third-party publication, so tier 6, but a documentable location match rather than rumor.
Tier 6
Direct naming (food media): 'Kirkland-branded beans ... are prepared by Starbucks, Rogers Family Co., and other recognizable brands,' and Rogers Family Co. 'produces Costco's Kirkland Signature Colombian Supremo Coffee ... in the Andes Mountains.' Uncorroborated ranked-list article (tier 6); it is the tier-6 direct naming that the tier-4 Costco Connection and the Coffee Review location back up.
Tier 4
Costco's own listing (2024-11-17 capture) names no roaster and carries no Starbucks credit — its feature list reads '100% Columbian Coffee / Dark Roast / Fine Grind / Supremo Bean' only. Establishes that the Colombian Supremo never carried the on-label Starbucks attribution and that the roaster is not printed on the package, so any maker attribution must come from off-label evidence.
