Laphroaig Quarter Cask is the whisky the distillery uses to show what happens to its peat in a small cask: 48%, no age statement, matured twice, first in ex-bourbon barrels and then in American oak quarter casks. In the UK it sells for around £47.

The bottle

A quarter cask holds 125 litres, a quarter of a five hundred litre butt. Laphroaig does not buy them in: it breaks down ex-bourbon barrels and reuses part of the staves to rebuild them smaller. The whisky matures in full size casks first, then moves into the small ones for a short spell, under a year.

The reason for that move is the ratio between surface and volume: fewer litres inside the same shape means more wood for every drop, so a faster exchange. Laphroaig gives 30% more contact with the wood than a standard cask. The whisky comes out at 48% and it is barrier filtered, the room temperature filtration that removes only the coarse residue.

The bottle came out in 2004. The format is much older: quarter casks were in use in the early nineteenth century, when full size casks were awkward to move.

Laphroaig was founded in 1815 by the Johnston brothers and now belongs to Suntory Global Spirits. It has seven stills, three for the first distillation and four for the second, and makes around 3.3 million litres a year. It still malts about 20% of what it uses, with the barley turned by hand for seven days and then ten to twelve hours of peat smoke in the kiln: that share of malt, more than the rest bought on the mainland, is where the medicinal character comes from.

Tasting notes

Nose: smouldering peat, coconut and banana, with the vanilla of the cask over the top. Laphroaig’s medicinal side is there but sits back, covered by the wood, and in its place comes a sweet note of fresh sawdust the 10 Year Old does not have.

Palate: full and warm, with sweet smoke and wood spice over the peat. The 48% gives it body and carries the move from the opening sweetness into the smoke, which arrives mid-palate and does not leave. It is fatter than the 10 and less sharp.

Finish: long, drying, with smoke and spice that hang around. It closes on toasted wood, which is the signature of the time in the small cask.

Within the Laphroaig range

Against the Laphroaig 10, bottled at 40%, the Quarter Cask has more body and more sweetness from the wood, while the 10 remains the reference for the medicinal notes. The full comparison is on our Laphroaig 10 vs Quarter Cask vs Select page, where the Select has the softest profile of the three.

The rest of the core range holds the Lore and the 10 Year Old Sherry Oak Finish, both at 48%, the 15 Year Old at 46%, back in the range for good since 29 June 2026, and the 18 Year Old. The Select was renamed Oak Select in 2024 with no change to the recipe.

Who it’s for

Laphroaig Quarter Cask is a whisky for anyone who already knows Laphroaig’s peat and wants it with more structure and more body, with the coconut and vanilla of the cask next to the smoke.

It is not for anyone fixated on age statements: the Quarter Cask carries no age statement, and the distillery does not say how long the second spell lasts either. And anyone after the medicinal Laphroaig, the iodine and bare peat one, will find it more directly in the 10 Year Old.

In the Quarter Cask the small cask brings the sweetness and spice of the wood over Laphroaig’s peat in a few months.
