Single-barrel bourbon does not eliminate barrel variation; it selects and preserves that variation as part of the product’s identity, while mingling pursues consistency by averaging barrels.
Single-barrel producers still select against acceptance criteria, so preserved variation is bounded rather than arbitrary. Producer-specific practices differ, and the term's complete present-day legal treatment is outside this synthesis.

Atomic idea
Single-barrel bourbon turns selected barrel variation into product identity, while mingling uses multiple selected barrels to move toward a repeatable profile.
Reasoning
Warehouse and barrel-position evidence establishes meaningful heterogeneity. Guglielmi states the producer-level choice; Lubbers independently contrasts small-batch consistency with barrel-to-barrel single-barrel difference; Bryson confirms the one-barrel versus multi-barrel assembly distinction. Minnick places the strategy in premium release history and sensory selection.
Counterpoint and limit
Single-barrel does not mean unselected or arbitrary. Producers can bound acceptable variation through tasting and specifications. Practices differ, and this idea is not a complete legal definition.
Provenance
Five connected Literature Notes carry rendered-sheet locators and reusable citations. The linked Claim contains the drafting-ready evidence chain.
Maturity decision
Established. Independent sources now corroborate both the maturation mechanism and the consumer-facing product strategy.
Proof — fresh source qualification
Fresh Proof review: PDF110 provides selection context, not proof that single-barrel bottlings are necessarily better. Keep selection, variation and quality judgments separate.
Risen2021 — September29 fresh ebook audit
Risen PDF53,70,118,121 mistakenly calls Booker's single-barrel. It is a small-batch product; this example must not support the single-barrel claim. Blanton's remains the book's relevant historical example. Preserve variation, barrel selection and proof as separate attributes.
Existing atomic statement, maturity and other source contributions retained.
Bourbon Land — fresh full-source qualification
Lee's Bourbon Land, PDF203–207, reports Minnick's observation that neighboring barrels may taste different. This is a practitioner illustration of heterogeneity, not a controlled experiment isolating location or evidence that single-barrel products are necessarily superior. The source adds a bounded example; existing maturity and other sources remain unchanged.
