Whisky tasting in Edinburgh: every option compared, from $27

People book a whisky tasting expecting a bar with a nicer list. It is not that. It is a structured hour with somebody whose job is to make five regional styles legible to you in a single sitting, and the structure is doing almost all of the work.

You are given a tulip-shaped nosing glass rather than a tumbler, because the shape concentrates the aromatics. You are asked to smell before you taste, because most of what you think is flavour is smell. You are poured in a sequence — usually Lowland, then Highland, then Speyside, then Islay, and Campbeltown if it appears at all — because each dram in that order makes the next one easier to read.

And somewhere in the middle you are told to add a drop of water, which sounds like vandalism and is not. Water breaks the surface tension and releases compounds the alcohol was holding down. On a cask-strength dram the difference is not subtle. It is the single most useful thing anybody will teach you on any tour in this city.

Five regions are recognised, and the reason a tasting works at all is that they sound genuinely different from one another. Learning to tell them apart is the skill you take home.

Lowland — light, grassy, often triple-distilled. Glenkinchie, fifteen miles from Edinburgh, is the classic and is the one most tastings here open with, partly out of local loyalty and partly because it is the gentlest place to start.

Highland — the largest region and the least consistent, which is not a criticism. It runs from delicate coastal malts to heavy, dried-fruit sherried whiskies, and a good host uses it to show you how wide the category is.

Speyside — around fifty distilleries in a small area, and the style most people picture when they think of Scotch: apple, honey, sherry cask. Formally recognised as a separate region only in 2014, despite being the biggest.

Islay — peat. This is the one that divides the room, and the one everybody remembers. Nine distilleries on an island off the west coast, drying their malt over peat smoke, and it comes through in the glass as smoke, iodine and sea air.

Campbeltown — three distilleries left, on a peninsula that was once the whisky capital of the world with more than thirty. If it appears in your flight, pay attention: it is the rarest thing on the table.

If what you want is the biggest still houses and the most famous names, they are four hours north of here and this city cannot pretend otherwise.

What Edinburgh has instead is density and teaching. In one afternoon on foot you can do a five-region tasting on Castlehill, walk twenty minutes to a working distillery, and be back on the Royal Mile for dinner. There is no equivalent of that anywhere in Speyside, where the distilleries are twenty miles apart and you need a designated driver.

So the honest framing is this: come to Edinburgh to learn whisky, and go to Speyside to drink it once you know what you are drinking. In that order, both trips are better.
