Like the Famous Grouse Experience at Glenturret, this is in fact a whisky based tourist attraction, Dewar's World of Whisky, more that a distillery tour, not that there is anything wrong with that.   The Aberfeldy distillery produces a single malt used in Dewar's blends, so it is a working distillery and you do get to see it and some more features like a video, a replica of Tommy Dewar's study, old Dewar's advertising and marketing material and an interesting aroma wheel.  At $11 they also charge more than most for the additional features.  After tour we sampled both Aberfeldy 12 year old single malt as well as Dewar's 12 year old blend and they also have small café where you can buy lunch, although they had run out when we got there.  I wouldn't say this is a must see for the whisky enthusiast, but quite honestly you are not their target market.  If you have non-whisky enthusiast in your entourage this might be a good compromise to go and visit.
