1. Ingredients: Irish whiskey is usually made up from the combination of malted and unmalted barley, and compared to Scotch whisky, which is produced from the mixture of malted barley and grains like wheat and rye.

2. Distillation Process: Most Irish whiskeys go through triple distillation and end up with a creamy overall texture in the mouth, while Scotch whiskies get by with double distillation and can therefore achieve more complexity in taste.

3. Peat Usage: Similarly, well-known Distilleries in Scotland use “peat” to dry “malted barley”, which leaves the resulting beverage with a smoky taste. On the contrary, known Distilleries in Ireland generally do not use “peat”, so they get a clean taste.

4. Regions: Scotland can be said to be the home of Scotch Whisky, and there are some areas here that are more or less well-known for their flavor notes. 

Irish whiskey is used to refer to the liquor that is made in Ireland as is the case with well-known brands namely Jameson and Bushmills.

6. Flavor Profile: To try the variability of scotch whisky, one should consider factors such as the place of distillation, aging, and variation in style, from peaty and smoky to fruity and floral.

9. Cask Types: Commonly, Scottish Whisky distillers exploit numerous cask types (such as barrels, sherry, and wine), which consequently create distinct flavors. 

Irish whiskey barrels are usually oak wood made and can be used as a finishing method for different woods in other cask types.

Lastly, both Irish whiskey and Scotch whisky, although having their origins too far apart in different countries, are well-known for their unique traditions, folklore, and style which are synonymous with their respective origin countries.

Is Scotch Whiskey More Expensive than Irish?

No doubt, one of the reasons that Scotch whisky is higher priced compared to Irish whiskey is several factors. 

In the second place, a variety of regions like Islay, Speyside, and the Highlands, each feature a unique set of flavors, resulting in huge price differences.

Scotch whisky tends to embrace long aging processes, utilizing distinctive casks like sherry or bourbon casks, which can escalate the costs associated with the process of production. 

Diffusion of peat acquires for some whiskies a peculiar flavor and they have to be made following a particular technology. Unlike scotch, Irish whiskey is distilled three times to give it a smoother taste, which potentially may mean a relatively lower cost of production. 

But then, there are differences, and some Irish whiskeys can of course command premium prices comparable to the ones sought after by connoisseurs of Scotch.

Unlike American whiskey which is much cheaper compared to their European counterparts, prices between Scotch and Irish whiskey have a broader range in the respective categories with cheaper and premium options for all budgets and preferences.


While the main differences between Irish and Scotch whiskeys concern the origins and raw materials, still usages, peat, regional origin, maturation methods, taste, legal definitions, spellings, and the cask types, there is something very similar – cultural being.

In addition, through joint production or cooperatives, the two countries produce products that have their particular features and competing prices to provide space for whiskey lovers to have choices to explore.
