Are you sure that Mac is worth opening ? It must be worth more than £400. I can't help but feel it moved from drinking to collecting catagories a few years back.
Yes, this would be considered a collectable by most and I am guessing that many would not drink it but look for resale. Fortunately I was able to pick it up a couple of years back in a very favorable trade so I am not too concerned on that front.
Also, as I am a drinker as well as a collector the intention of my collecting was not only to have an enjoyable hobby, that in the end could hopefully pay for itself, but also to be able to use the ROI from some of the more collectable or in demand whiskies to allow me to actually grow my collection and most importantly drink some of the rare and/or vintage whiskies that I have that I could not afford to purchase outright and drink due to monetary constraints. (Sorry for the run on sentence).
I have heard that the 50's Macs are an experience none should miss out on and as I have yet to try one, I am really eager to try it as well. Thus my quandry with the selection above.
