This guide links to retailers. Some links may earn us a commission; picks are based on the price data and the criteria below.

Short answer: pick by cask. For bourbon casks, start with Deanston 12 Year Old; for sherry casks, Tamdhu 12 Year Old Sherry Cask Matured; for smoke, Ardbeg 10 Year Old; and for a single malt from outside Scotland, Yamazaki 12 Year Old or Kavalan Classic. Every single malt we track is on single malt.

Single malt is a category, not a country: it means malt whisky from one distillery, and it is made in Scotland, Japan, Ireland, Wales, Taiwan and elsewhere. This guide groups widely stocked single malts by the cask that shaped them, one of the biggest influences on how a malt tastes, then ends with single malts from outside Scotland. For Scotch by region and blend instead, see best Scotch whisky.

A single malt is not better than a blend by definition: the two are different categories. “Single” refers to the distillery, not the cask, so most single malts combine many casks from one place (what single malt Scotch means). For one pick from every style, see the best whisky to buy in the UK.

Bourbon and American oak casks

US law requires bourbon to be matured in new charred oak containers (27 CFR 5.143), so a cask that has held bourbon cannot hold bourbon again. Scotch distillers reuse them, and Deanston is one example.

Deanston 12 Year Old: £35.95 at Master of Malt. A 12-year-old Highland single malt at 46.3% ABV from Deanston, which names bourbon casks for it and says its core range is not chill filtered and has no colour added.

Balvenie The Sweet Toast of American Oak 12 Year Old: £49.00 at The Whisky Shop. A 12-year-old Speyside single malt at 43% ABV from Balvenie, named, as the label says, for its American oak.

All of them: bourbon cask whisky.

Sherry-cask single malts

Tamdhu 12 Year Old Sherry Cask Matured: £49.90 at Tyndrum Whisky. A 12-year-old Speyside single malt at 43% ABV from Tamdhu, matured in sherry casks, as its name states.

Benromach 12 Year Old Sherry Cask Matured: £44.95 at Master of Malt. A 12-year-old Speyside single malt at 46% ABV from Benromach, also named for its sherry-cask maturation.

The sherry-cask guide explains oloroso, Pedro Ximénez and the difference between maturing and finishing.

Wine and port casks

The Dalmore Port Wood Reserve: £69.95 at Hard To Find Whisky. A Highland single malt at 46.5% ABV from Dalmore, named for the port wood casks it spends time in.

Ledaig Sinclair Series Rioja Cask Finish: £33.92 at Master of Malt. A single malt at 46.3% ABV from Tobermory distillery on Mull, sold under its Ledaig name and finished in Rioja wine casks, as its name states.

More: port cask and wine cask whisky.

Peated single malts

Peat is not a cask, but it marks a malt as clearly as one, so it gets its own section.

Kilchoman Rockside Farm 11 Year Old: £54.99 at Tyndrum Whisky. An 11-year-old Islay single malt at 46% ABV. Kilchoman says its Rockside releases are grown, malted, peated, distilled, matured and bottled on Rockside Farm.

Ardbeg 10 Year Old: £39.95 at Hard To Find Whisky. A 10-year-old Islay single malt at 46% ABV from Ardbeg, which describes its whisky as peaty and smoky.

For smoke at every level, see best peated and smoky whisky.

Single malts from outside Scotland

Yamazaki 12 Year Old: £120.00 at Loch Fyne Whiskies. A 12-year-old single malt at 43% ABV from Suntory’s Yamazaki distillery, founded in 1923.

Kavalan Classic: £67.95 at Master of Malt. A Taiwanese single malt at 40% ABV from Kavalan, founded in 2005 in Yilan.

Penderyn Portwood: £54.50 at Master of Malt. A Welsh single malt at 46% ABV from Penderyn, founded in 2004, named for its port wood casks.

Bushmills 10 Year Old: £35.95 at Master of Malt. A 10-year-old Irish single malt at 40% ABV from Bushmills in County Antrim.

How we chose

Member ratings are not shown on this site yet, so these picks are not ranked by score, and we have not ranked them against each other. We grouped single malts by cask, using only casks named on the label or stated by the producer, not inferred from tasting notes. Each pick is a full-size bottle (50cl to 1 litre) sold by at least three UK retailers we check on 11 November 2026 (Kavalan Classic by two), favouring core-range bottles over limited editions; the picks span the £30 to £50 and £50 to £100 bands, with Yamazaki 12 Year Old above them. None repeats a pick on best Scotch whisky. Founding years come from our distillery database and ages and strengths from the bottle details; the lines are label facts, not tasting notes. Prices change daily, and the retailer’s checkout price is the one that counts. Read how we compare prices.

Questions

What does single malt mean?
For Scotch, it means whisky made at one distillery from water and malted barley only, distilled in pot stills (Scotch Whisky Regulations 2009, regulation 3). Single refers to the distillery, not the cask: Deanston 12 Year Old, for example, is a single malt drawn from many casks at the Deanston distillery.
Can single malt whisky come from outside Scotland?
Yes. Yamazaki 12 Year Old (Japan, 43% ABV), Kavalan Classic (Taiwan, 40% ABV), Penderyn Portwood (Wales, 46% ABV) and Bushmills 10 Year Old (Northern Ireland, 40% ABV) are all single malts. Each country sets its own rules; only Scotch single malt is bound by the Scotch Whisky Regulations 2009.
What is the difference between single malt and single cask?
A single cask bottling comes from one cask, so each release differs and the number of bottles is limited by the size of that cask; a single malt is usually a vatting of many casks from one distillery. A single cask whisky can also be a single malt, when the cask was filled at one malt distillery (single cask whisky explained).
