I have no doubt that Ardbeg puts out some excellent whiskys in fact I know they do. However I don't think the speculators can have as big an impact on a 5000 release of Ardbeg as people think. I personally put it down to the fact of it being a pure cult distillery and the distillery really plays on that and between the distillery and the Ardbeg fans they create the hype amonst themselves.
In relation to this expression collectors and fans are paying over the odds now in the blind knowledge that the next and subquent versions will not be of similar quality.
I personally feel the Ardbeg will slowly become a Bruichladdich with so many different expressions that it will eventually dilute the so called collector status of the Distillery.
Sell now while the going is goood
