Shell-and-tube condenser
No legal definition
The standard modern condenser: a shell containing a bundle of copper tubes through which cooling water passes, condensing spirit vapour against a large copper surface area.
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
Copper reacts with sulphur compounds, so more copper contact means cleaner spirit. Warm condenser water is sometimes used deliberately to reduce that scrubbing and push spirit towards a heavier style.
