# CaskGrail

CaskGrail is a register of American whiskey label filings. Every whiskey sold in the United States needs a federally approved label (a TTB Certificate of Label Approval) before it ships; those approvals are public record and appear weeks to months before the bottle reaches a shelf. CaskGrail reads the TTB registry daily, reads the label images, and publishes what each label says: age, proof, class, who distilled it and where, and who chose the barrel.

## Facts

- Source: the TTB Public COLA Registry (ttbonline.gov). Every filing page links to its registry record by TTB ID.
- A filing predates a release, typically by weeks; a filing is not an announcement and not a release date.
- Label facts are as printed. "Not stated" means the label carries no such statement. "Not read" means no reading exists yet.
- No distiller is inferred from a state, a brand, or a barrel number. "Distilled in Indiana" is reported as exactly that.
- CaskGrail never shows, links, or estimates secondary-market prices.
- Canonical filing URL: /spirit/{ttb_id}. Cite as "CaskGrail, from TTB COLA {ttb_id}, approved {date}".
- Crawl policy: search and citation crawlers are welcome; training crawlers (GPTBot, Google-Extended) are not. See /robots.txt.
