How Much Tax Is on a Bottle of American Whiskey in the UK?
Bourbon, rye, Tennessee whiskey — American whiskey has never been more popular in the UK. But if you've ever looked at the price of a bottle and wondered how much of it goes straight to HMRC, you're not alone. The UK applies two layers of tax to all spirits, including imported American whiskey: excise duty and VAT.
The Two Taxes on American Whiskey
1. Excise Duty (Spirits Duty)
Since August 2023, the UK reformed its alcohol duty system. All spirits — including bourbon, rye, and Tennessee whiskey — are now taxed based on their alcoholic strength by volume (ABV) and the total volume of pure alcohol in the bottle, regardless of origin.
The current rate is £31.64 per litre of pure alcohol (LPA).
The formula is:
Excise Duty = Volume (litres) × ABV × £31.64
2. VAT
VAT is charged at the standard UK rate of 20% on the full retail price — which already includes the excise duty. In effect, you're paying tax on top of tax.
A Real-World Example: A Cask-Strength Bourbon at 58.4% ABV
Let's use a high-ABV American whiskey as our example — a 70cl bottle of cask-strength bourbon bottled at 58.4% ABV (think along the lines of a Four Roses Single Barrel or a FEW Bourbon.), retailing at £65.00.
Step 1 — Calculate Excise Duty
0.70 litres × 0.584 ABV × £31.64 = £12.94 in excise duty
Step 2 — Calculate VAT
VAT is 20% of the retail price: £65.00 × 0.20 = £10.83 in VAT
Step 3 — Total Tax
£12.94 + £10.83 = £23.77 in tax
That means on a £65 bottle, roughly 37p in every £1 goes to HMRC — before the retailer, importer, and distillery take their cut.
Why High-ABV American Whiskeys Are Taxed More
Under the reformed duty system, a cask-strength bourbon pays significantly more excise duty than a standard 40% ABV expression. Here's a quick comparison on a 70cl bottle:
- 70cl at 40% ABV (e.g. standard Jim Beam): 0.70 × 0.40 × £31.64 = £8.86 excise duty
- 70cl at 58.4% ABV (e.g. cask-strength bourbon): 0.70 × 0.584 × £31.64 = £12.94 excise duty
That's over £4 more in duty per bottle purely because of the higher alcohol content. The reformed system was designed to do exactly this — tax alcohol proportionally to its strength rather than applying a flat rate per bottle.
Does Being American-Made Change the Tax?
No — UK spirits duty applies equally to all spirits regardless of country of origin. A Kentucky straight bourbon pays the same duty rate as a Scotch whisky or an Irish whiskey of the same ABV and volume. There are no preferential duty rates for American whiskey in the UK, and post-Brexit trade negotiations have not resulted in a spirits duty exemption for US imports.
What can vary is the import duty applied when the whiskey enters the UK from the US. However, for most standard retail bottles, this cost is absorbed into the wholesale price before it reaches the shelf.
What This Means When You're Buying American Whiskey
When comparing a standard-strength bourbon to a cask-strength expression, part of the price gap is simply the duty difference. Cask-strength American whiskeys aren't just more expensive because they're rarer or more sought-after — they're also carrying a heavier tax burden per bottle.
It also explains why some American distilleries bottle at 46% or 50% for the UK market rather than full cask strength — there's a meaningful duty saving that can make the bottle more competitively priced.
The Bottom Line
On a 70cl bottle of cask-strength American bourbon at 58.4% ABV retailing at £65:
- Excise duty: £12.94
- VAT: £10.83
- Total tax: £23.77
- Tax as % of retail price: ~37%
The UK is one of the most heavily taxed spirits markets in the world. So the next time you crack open a bottle of high-proof bourbon, you can appreciate just how much of that price tag is going to the government — and how much is going to the craft of the distiller.
