Here is the response I received. So... an online gift certificate emailed to him for a Scotch seller online would probably work, I am going to ask him :)
Thank you XXXX for your interest and support. Thank you also for the offer of a bottle of Scotch. I must say that your mail is more than adequate thanks and even if you were to send me a bottle I would unfortunately probably have to trash it as there may be people out there wishing me harm. So please accept that your mail on its own means a lot to me.
Kind regards
