Master of Malt listed three independently bottled Islay single malts on 8 September 2026, gathered under the name The Islay. None of the three says which distillery it comes from: in place of the name there are three rocks found on the island, basalt, red sandstone and quartzite.
Release details
The Islay Basalt is 16 years old and costs £99, Red Sandstone is 20 years old at £149.95, Quartzite is 30 years old at £499.95. All three are bottled at 46.3% in 700 ml. The design comes from London studio Studio Minerva.
Sam Simmons, who runs the whisky side of Master of Malt, was after a profile that reads as “unmistakably Islay”: minerality, sweetness underneath and coastal peat.
How the rolling cask works
Each expression comes from a single cask: when it runs out, another cask takes its place with the same name, the same age and the same strength. Master of Malt calls it a rolling cask model. The range stays on the shelf permanently, but the liquid changes with every round, the way it does with numbered cask strength editions.
Who is usually behind the anonymous labels
When a bottle of Islay whisky does not name the distillery, the attribution that circulates among enthusiasts and trade press is almost always Caol Ila, less often Ardbeg, rarely Laphroaig. No bottler ever confirms it, but there is a reason behind it: Caol Ila is the largest distillery on the island, 6.5 million litres a year, and sends almost everything it makes into Diageo blends, Johnnie Walker first among them. Until 2002, the year of the first official 12 year old, anyone who wanted to drink it as a single malt had to go through the independents.
With Laphroaig the mechanism is a different one. Casks leaving the distillery are often teaspooned: they get a spoonful of whisky from another distillery, which under Scotch law stops them being single malt, so they can no longer be sold under the distillery’s name. That is where the name Williamson comes from, the one independent Laphroaig has been going by for years. A range that presents itself as single malt, as The Islay does, has not been through that.
An Islay single malt that does not name its distillery costs less than one that does. The buyer knows only part of what is in the bottle and pays less for it: £99 for a 16 year old from the island, when official bottlings of the same age start a good deal higher.
