Absolutely. I can (more or less) tell when a whisky is good, as in being well made etc., but that doesn't mean I'll like it as a whisky to drink. For example, I have a real blind spot about Cragganmore: I can tell that it is very well made, complex, balanced, full of character - but it just doesn't ring my bell. On my own rough and ready scale, being a "good whisky" gets it up to about 8 - the rest is "do I like it" and "am I in the mood" element: there aren't that many whiskies I can drink and enjoy the same any time regardless of mood. On that basis, my "close to 10" list is Springbank 15, 21 or CV (whatever happened to that?), Highland Park 18, Glengoyne 17, Ardbeg 17, Macallan 30s or 40s, Old Rip Van Winkle 15, Longmorn 15, Talisker and Lagavulin Distiller's Editions, Black Bottle 10 and pretty much any Mortlach or Balvenie.
