Who makes Kirkland Signature Small Batch Kentucky Straight Bourbon (line incl. Bottled-in-Bond and Single Barrel)?
As of July 5, 2026, the manufacturer of Kirkland Signature Small Batch Kentucky Straight Bourbon (line incl. Bottled-in-Bond and Single Barrel) is Barton 1792 Distillery (Sazerac Company), per on-label, first-party, or executive statement evidence.
The common claim
What most answers say — and what the evidence supports
Top-ranking answers name Barton 1792 in Bardstown, Kentucky — and here the consensus holds up: the current bottles state it on the front label ("Barton 1792 Master Distillers"), and Forbes documented in 2021 that the latest expressions are sourced from Barton 1792, a Sazerac-owned distillery. What most answers skip is that this was not always true — PUNCH reported in 2017, citing TTB filings, that an earlier Kirkland bourbon was Jim Beam-distilled, and Forbes lists a George Dickel period before Barton — so older reviews and Reddit threads may describe a different whiskey than what is on the shelf today.
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
"The latest bourbon expressions, however, clearly state that the spirit is sourced from Barton 1792. Barton is a Sazerac owned company." The label itself carries the attribution — Micallef reproduces it: "Kirkland Signature, Small Batch, Barton 1792 Master Distillers, Kentucky Straight Bourbon Whiskey, NAS, 46% ABV, 1 liter." Also documents the pre-Barton history: "Costco's original bourbon bottlings were sourced from Jim Beam and then George Dickel before ending up with Barton."
Tier 6
Tier-6 recency corroboration alongside the tier-4 anchor (batteries pattern): confirms the Barton attribution is still current and still label-verifiable as of April 2026 — "Kirkland Signature has offered various bourbons over the years, currently a small batch version, all produced by Barton Master Distillers. The Barton 1792 distillery is in the bourbon hotspot of Bardstown, Ky."
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 | Barton 1792 Distillery (Sazerac Company)Current | Current attribution — confirmed. See the evidence and fact sentence above. | Evidence ↑ |
| … → unknown | Jim Beam | The earliest Kirkland bourbon bottlings were Jim Beam-distilled: PUNCH (2017) reported "their previous bourbon was Jim Beam juice (according to TTB filings)," and Forbes (2021) independently listed Jim Beam as the first source. Exact years are not publicly documented. | PUNCH ↗ |
| … → unknown | George Dickel | Forbes (2021) reported an interim George Dickel-sourced period between the Jim Beam era and Barton: "Costco's original bourbon bottlings were sourced from Jim Beam and then George Dickel before ending up with Barton." Dates are not publicly documented, and PUNCH (2017) associated Dickel with the Kirkland Tennessee whiskey line rather than the bourbon — so this window rests on the single Forbes statement. | Forbes ↗ |
