What is Scotch (and its Regions)

Whisky education from Whisk(e)y Advent 2025 (2025-12-02). Summary below; full write-up with sources and images: calendar/2025-12-02.qmd.

Scotch is distilled in Scotland from water, malted barley and yeast, matured >=3 years in oak. Single malt = malt from one distillery in pot stills. Regions signal style by tradition: peat-poor Speyside trends smooth and fruity; peaty regions like Islay trend earthy and smoky.

Scotch whisky is required by law to be:

produced at a single distillery in Scotland from water, malted barley, and yeast
matured in a warehouse in Scotland in oak casks for at least three years
contains no added substances other than water and plain caramel colouring
has a minimum ABV of 40%

Malted barley is barley which has been soaked in water and allowed to germinate, converting the unfermentable starch in the grain into fermentable sugars.

A single malt Scotch whisky is produced from malt in one distillery, and entirely in pot stills.

When a single malt whisky has an age statement like ours today does, it means that the youngest batch of whisky blended with other single malts is as old as the age statement.

It’s common to see single malt scotch whisky finished in additional casks other than oak (such as sherry, port, rum, or ex-bourbon casks) for additional character. We’ll see an example of this coming up soon.

Scotch Regions

The region of Scotland that a scotch is produced in often will say something about the tasting notes or style you can expect. This is driven by the tradition of scotch-making in the region. The Glenlivit Distillery is in the Speyside region of Scotland, which is a small region in the north of Scotland.

Many of the distilleries in the Speyside region lie on the River Spey, where the distilleries source their water from. The Speyside region is also lacking in peatlands, which makes peat an inconvenient fuel source for malting.

In regions where peat was a more common fuel source, it is more common to have scotch styles that have a characteristic earthy or smokey taste (sometimes described as “peaty”). This is typical of Islay styles, which we’ll see coming up. Since Speyside is a peat-poor region, scotches from this region are often smooth, easy-drinking, and have more delicate tasting notes. Common flavors/aromas that you might find in a Speyside scotch include:

Fresh fruits (apple, pear, citrus, stone fruit)
Dried fruits (raisins, figs, dates)
Vanilla, honey, caramel
Warming spices or nuttiness
Floral or herbal notes
