Dear Daniel,
Your enquiry has been passed on to us here at the Diageo archive from Joanne at Whisky.com
We have bottles the same as your 8 YO Dufftown Glenlivet in our historic bottle collection which are dated c.1980s, however you will be pleased to hear that I have found evidence of this bottle being marketed as early as 1978. This particular bottle continuted to be maketed into the 80s and I have found examples as late as 1985, so from the evidence I have,
your bottle will have been purchased sometime between 1978 and 1985. Therefore it could well be 30 years old.I hope this information is of help.
If you have any further questions, please do not hesitate to contact me.
Kind regards,
Alia Campbell
@JoJo: Thank you very much for helping me. The bottle is probably as old as me. I will enjoy the whisky
