A friend has a very rare knappogue castle cask? (I can not remember the cask no.he said) 1951 36 year old not the usual 1951 but a single cask!
He wants to hold onto this bottle as an "investment" / a special occasion but would like to know the value of the bottle if was being sold at auction or somewhere just so as he knows the value of his bottle!
Cheers for any details!
