I respectfully disagree with that notion! I Really enjoy having a variety at hand, especially to help develop my palate and realize the differences in taste and aroma that different distilleries, regions, and bottlings can offer. I love a good Islay like Laphroaig or Lagavulin with a good cigar, but sometimes prefer some sweeter and lighter tastes that some Highlands Whiskeys can offer.
Another reason to keep some of a bottle around is for comparison. I recently performed two blind taste tests along with a friend on different occasions between the Laphroaig 15 and Laphroaig 18. On each of the two occasions we performed three consecutive blind tests. On both occasions, neither of us was able to identify with anything surpassing luck, the 18 from the 15. So for me, the extra money for the 18 doesn't make sense, either my palate isn't matured enough yet, or there isn't an appreciable difference between the two.
That and other blind taste tests I've done like it would be impossible without a variety.
