cask

Butt

No legal definition

A cask of approximately 500 litres, tall and comparatively narrow — the standard format for sherry-seasoned European oak in Scotch maturation.

Not a legal term

No whisky regulation in Scotland, Ireland, the United States, the EU or Japan defines this. It is a trade or marketing term, so it is only actionable if its use is actively misleading.

Worth knowing

Traditionally the sherry butt (bota) of Jerez; the industry now largely uses purpose-made seasoning butts. A butt's low surface-area-to-volume ratio means slower extraction than a barrel, despite sherry casks' reputation for fast colour.
