Scotch whisky is usually made from distilled barley, using a variety of different malts and alcohol levels up to 60% or more for a stronger flavor, and is often aged for years in oak barrels for a more mature and complex taste. Scotch whisky is also categorized into two types: single malt whisky and blended whisky, where single malt whisky refers to whisky that comes from the same distillery and is made using the same malt, yeast, water source, and distillation equipment, while blended whisky is a mix of different types of whisky from multiple distilleries.
While Irish whiskey is usually made using a mix of grains such as barley, corn and buckwheat, some of these Irish whiskeys are also made using triple distillation and have a lower alcohol content, up to 40%. Irish whiskey has a smooth texture and a rich, fruity flavor, making it easier to consume and not requiring too much tasting knowledge.
Overall, Scotch whisky has a strong flavor and complex aroma, while Irish whiskey is softer and more palatable. Different consumers have different taste preferences, and with both whiskey types having their own unique appeal, it's hard to say which is superior.
