For the purpose of definition we'll call 'rare 18 year old Scotch' bottles that aren't really common in foreign markets like Canada.
What I wonder is, if we're talking about that type of high-grade Scotch, how easy is it to find a bottle if you were visiting distilleries or liquor stores in Scotland directly.
In other words, when distilleries produce premium product does it tend to mostly stay in country, or are some of these whiskies just produced in such low quantities that getting your hands on it anywhere is rare?
