Bourbon Barrels
Fresh full-copy audit: 302 sheets read and visually surveyed; selected evidence rechecked in enlarged renders. The downstream cask market is the supported idea. Current 27 CFR 5.143 requires new charred oak for bourbon but does not require 53 US gallons, American white oak, malted barley or rye/wheat in the remainder of the mash. Distillation/entry maxima include 160/125 proof; source strict-below wording is inaccurate. https://www.ecfr.gov/current/title-27/chapter-I/subchapter-A/part-5/subpart-I/section-5.143 Verification concerns source fidelity, not independent endorsement of every source assertion.
One Citation record represents one source-and-locator reference. It must be reusable, verifiable, and connected to every evidence object that depends on it.
