rob,
No bottling number on a single caks bottling, that 's strange indeed...
I think your comments are facsinating. I remember writing on my blog that the Balvenie 15 was too good to be true at its current price (A single cask bottle for $50). I had predicted a price raise. If what you say is not just an occurence of "mysteriously disappearing ink"

(see othe post) then I should have realised that standards would go down...
This also reminds me of the demise of the Macallan 18 (may it r.i.p.) which used to note the date of distillation AND bottling on its label.
I don't know about the Balvenie (waiting for other posts --going to the liquor store today to check things out) but what happened to the Macallan 18 was a shame, it went from being a Vintage Single malt to a standard 18 year old (a BIG difference), and the good folks at the MAcallan tried to put it past us. At the Balvenie, if confirmed, the alleged action would be another stone in the wall that is the decline of standards in the sms industry...
THanks for the post rob!
