I'm a Scotch/whisky nerd going on 10 years now. Particularly obsessed with anything from Islay. 50+ bottle collection, mostly easy-to-find stuff but there are a few rare expressions in there (Ardbeg 2009 Committee Release Supernova is probably the most unobtainable). I'm a drinker, not a collector, everything has been opened and consumed at least partially.
With that out there, I don't get the buzz over Japanese whisky. I've got several solid, highly reviewed expressions, including the 2013 sherried Yamazaki that Jim Murray put on the map. I've done several blind tasting with friends, some of whom are afficionados and some of whom are not, and that Yamazaki never comes out on top. If I do a sherry-finished flight more often than not the sherried Kilchoman finishes first or second, with the Yamazki usually beating the Glenmorangie Lasanta and not much else. Laphroaig PX either wins or comes second to the Kilchoman.
Japanese whisky is good and they're consistently making the best whisky that's not coming from the island. But (IMO, of course, this is completely non-objective) the best expressions are still coming from Scotland.
