Who makes Kirkland Signature Tennessee Sour Mash Whiskey, Aged 4 Years (1.75 L)?
As of July 6, 2026, evidence points to Tennessee Distilling Group as the manufacturer of Kirkland Signature Tennessee Sour Mash Whiskey, Aged 4 Years (1.75 L), but no tier 1–3 source names the link directly.
The common claim
What most answers say — and what the evidence supports
The most-repeated answer online is George Dickel — PUNCH relayed in 2017 that "it's believed" the Kirkland Tennessee whiskey came from George Dickel (Diageo's Cascade Hollow distillery), and the guess still circulates. The bottle points elsewhere: it carries a "bottled by Tennessee Distilling" statement and the signature of Tennessee Distilling Company's master distiller, Mike Williams (Forbes, 2021; independent label transcription by Sipology, 2021), so the evidence points to Tennessee Distilling Group of Columbia, Tennessee — the same contract distiller behind Kirkland's London Dry Gin — as the producer of record. Two things keep this short of certainty: the label reads "bottled by" rather than "distilled and bottled by," so the distillate's origin is not stated outright, and Costco does not disclose its spirits suppliers. No evidence supports the George Dickel attribution, which the current Tennessee Distilling bottling appears to contradict.
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 4
Primary bottler-of-record anchor: "Every bottle of Kirkland Signature Tennessee Whiskey carries the signature of Master Distiller Mike Williams. Williams is the Master Distiller at Tennessee Distilling Company. Each bottle also states that the whiskey is bottled by Tennessee Distilling. Presumably they are also making the whiskey that goes into the Kirkland Signature Tennessee Whiskey." Mash bill given as 70% corn / 15% barley / 15% rye. The label names Tennessee Distilling as bottler; Micallef only *infers* ("Presumably") that they also distill it, and there is no on-label "distilled by" statement — which is why this caps at probable, not confirmed. Also: "Stylistically, the Kirkland Signature Tennessee Whiskey falls between Jack Daniels and George Dickel" (a taste comparison, not a sourcing claim).
Tier 4
Independent bottle-in-hand label transcription: "Maker: Tennessee Distilling, ltd, Columbia, Tennessee, USA. Distiller: Undisclosed (almost certainly George Dickel). Style: (Straight?) Tennessee Whiskey. Age: 4 y/o. Proof: 80 (40% ABV)." The reviewer records the on-bottle bottler as Tennessee Distilling, Ltd. and the distillery as undisclosed, and flags the George Dickel attribution as his own speculation ("I would be truly shocked if this was from anywhere else"), not a label or registry fact.
Tier 6
Debunk source for the George Dickel claim (tier-6 belief, cited because it carries the counter-argument): "It's believed that Kirkland's Canadian whisky comes from Crown Royal and the current Tennessee whiskey from George Dickel." Presented explicitly as belief, with no label, COLA, or registry support; later bottle transcriptions (Forbes 2021, Sipology 2021) name Tennessee Distilling as the bottler instead. Included per the rule that negative/debunk sources belong in sources[].
