What is a Single Malt Whisky?

The name doesn't mean what you think
Most people assume "single malt" means the whisky came from a single barrel, or that it was distilled once, or that it's somehow purer than other whiskies. None of these are true.
The term has two parts, and both matter.
Single refers to the distillery. A single malt comes from one distillery only. No spirit from another site has been blended in.
Malt refers to the grain. Single malts are made exclusively from malted barley, distilled in pot stills, and matured in oak casks for a minimum of three years (in Scotland).
That's it. One distillery, malted barley, pot stills, oak casks. A bottle of Glenfiddich 12 might contain whisky from dozens of different casks, all matured at different rates and blended together before bottling. It's still a single malt, because every drop of it was made at Glenfiddich's distillery in Speyside.
So what's a blended whisky?
A blended Scotch whisky combines malt whisky from multiple distilleries with grain whisky, which is made from other cereals in continuous column stills. Famous blends like Johnnie Walker, Chivas Regal, and Monkey Shoulder are carefully crafted combinations that might draw on dozens of different distilleries.
There's a common assumption that blends are inferior to single malts. This is snobbery, not fact. A well-made blend is a genuine craft, and many are exceptional whiskies. The distinction is about process and provenance, not quality.

Does single malt taste different?
In general, single malts tend to show more of the character of a specific place and distillery. Because you're drinking spirit from one source, the house style of that distillery comes through clearly. Laphroaig tastes like Laphroaig. Glenfarclas tastes like Glenfarclas. There's a directness to it.
Blends, by contrast, are often smoother and more consistent. The blender's job is to create a harmonious whole from many parts, which usually means softening the rough edges that make individual distilleries distinctive.
Neither is better. They're just different things.
Does age matter?
An age statement on a single malt tells you the minimum age of the whisky in the bottle. A 12 Year Old Scotch has been matured for at least 12 years. If a blend of younger and older casks went into the bottle, the youngest determines the number on the label.
Older isn't automatically better. Some whiskies peak young. Some benefit from 20 or 30 years in wood. Some spend too long in a poor quality cask and end up over-oaked and astringent. Age is a data point, not a verdict.
Single malt vs single cask
Single cask whiskies are rarer and more expensive. They come from one specific barrel, undiluted and unblended with anything else. Every bottle from that cask will be slightly different, and once the cask is empty, that particular expression is gone forever.
Single malts are blended across many casks to achieve a consistent profile year after year. Single cask releases are the opposite: unique, variable, and unrepeatable.
Where to start
If you're new to single malts, Speyside is the most welcoming place to begin. The whiskies tend to be approachable and fruit-forward, with little or no smoke.
From there, work outward at your own pace. Try a Highland for more body and spice. Dip into Islay when you're ready for something more challenging. There's no correct order and no wrong choices.
