How about a whiskey tasting set or kit? You can get a set that comes with several different types of whiskey for him to sample and compare. Another option could be to get him a subscription to a whiskey of the month club, where he can receive a new type of whiskey to try each month. Additionally, you could consider getting him a personalized whiskey glass with his name or favorite quote etched onto it.
Or you can get him a star map with the date when he welcomed you in this world.
