Unique and valuable gift for drinker? I want to give a close friend a unique and memorable liquor-related (his stipulation) gift. He's particularly fond of whiskey and beer but drinks most anything. What are some ideas, not necessarily limited to actual liquor? In the past I've given him special whiskey glasses, a $100 bottle of whiskey, a home brew kit, and a bottle of chartreuse. He's got a pewter stein he bought himself. Think big, between $100 and $200.
While:


this might not be the type of drink they like
this was a numbered birthday present
this website is in the UK


Nonetheless, it might spark off some ideas: https://www.thewhiskyexchange.com/p/18434/grahams-40-year-old-tawny-port

It was his 40th birthday, so a 40 year old port with a custom engraved bottle. He's a Tolkein fan, so the inscription read: "Such an excellent and admirable hobbit"
