Okay, first of all I have to admit that it has been a good while since I have had a bottle of my particular preferred tipple, the reason being that at over £60 a bottle, its not an everyday drink (even less so, the £400 a bottle "last cask" version).
The Dallas Dhu distillery ceased production in 1983, and ever since, they've been bottling from their vast stocks, this means that every year, the number of potential bottles becomes more limited. It is also now a museum, and if anyone is in the area of it, I thoroughly recommend the tour as about the only distillery tour that allows you to stick your head inside the stills. It allows a persective that you just can't get in an operational distillery.
Aromawise, it is slightly spicy and floral, with a cedar edge, the taste being similar with a kick and dry smoke backdraft.
Gordon & Macphail usually have miniatures avaliable for the 'taster' though I don't believe these portray the whisky fairly.
