Ready for a national or international tour?

Depending on how your tasting is tailored, questions like these might be answered:

• What are the characteristics and flavour profiles of the different Scotch whisky regions?
• What are the characteristics and flavour profiles of whisky from the other UK nations?
• What is different about Irish whiskey (and why do they spell it with an e?)
• What are bourbons and other US whiskies (and why do they have an e too?)
• What is special about Japanese whisky (and why don't they use an e?)
• Could I go on a "world tour of whisk(e)y" taking in each continent? (Spoiler - you really could, yes. Whisky is made in every continent except Antarctica.)
