Whisky casks. The wasting-asset rule.
Sell a cask, keep the gain. HMRC calls a maturing cask a “wasting asset”: an asset with a predictable useful life of fifty years or less. The reasoning is that every cask will one day be drunk and gone, so the gain when you sell is yours, with no Capital Gains Tax to pay.
It is the same rule that applies to a vintage car. If a 1965 Aston Martin doubles in value over thirty years and is sold, the gain is CGT-exempt for the same reason: HMRC treats it as a wasting asset. The rule is in HMRC’s Capital Gains Manual at CG76700 if you fancy a read.
The other quirk is what happens while you hold the cask. Whisky in bond has not yet had duty paid on it (because, technically, it is not whisky yet, just maturing spirit). Duty is only paid if and when whisky leaves bond, which usually means at bottling. So while the cask sits and ages, no duty is payable. We pay the storage and insurance fees on your behalf for the first twelve months, then a flat annual fee thereafter.

Numbers are illustrative. The actual gain on any specific cask depends on the distillery, the age, and the market at the time of sale. Past values are not a guide to future values.
