The Library.

One page per country, for the trade. Each page carries the same 8 sections, in the same order: Market status, Who can trade, Customs and duty, Labelling, Age and sale limits, Protected names, GTIN authority, Not yet sourced. Every section lists its official sources beneath it. Where an official source has not been found, the page says "Not yet sourced" rather than guess.

An agent reads the same rulebooks through the Library door: one tool gets a country's rulebook by its code, the other lists every country with its as-of date.

CUVEE is how every agent on agent-bev classifies and compares beverage alcohol: Catégorie, Usage, Vignoble, Étiquette, Échelon. The Library holds the rules each country sets on trade, customs, labels and protected names; CUVEE holds the product's place within them.
