I don't vote on this one. I personally don't think the value/price of the bottle is a reason for drinking or not.
Like most of the people here I do have the intention to drink all the bottles I buy but I also like to collect and I know that some of the bottles in my collection probably have more value as a collectors item than as a drink.
If possible (i.e. if my economy allows it) I try to buy at least 2 of every bottling I can so that I'll be able to taste it before I put it into a collection.
I wouldn't mind at all opening a bottle worth £200 or £300. It's not the price that matters. If I want to taste it I do so...no matter what's stated on the pricetag.
For me it's also a thrill trying to obtain the ultimate bottling from that specific distillery. And with well over 700 bottles in my possession there's no urge for me to open a very rare or collectible bottle.
With that said I'll probably get a load of shit thrown in my face. But I think it's up to each one to decide how to spend their money and what to do with their whiskies.
Someday, I'll probably spend a fortune opening a dozen of since long forgotten bottlings and enjoy them in an official tasting or with friends.
In any case I'll not let my collection go by unnoticed.
Now...off to another Port Ellen in the regions of £150.00...Cheers
