I'm a father-to-be and am wanting to get a decent bottling of an as yet undecided scotch (preferably single malt) near the date of birth that will then be held on to as a gift for their 21st birthday. I'm not really a scotch drinker so I'm not even sure if this is possible, so I'm hoping to get some feedback.

Is it possible? If so, what brands or places should I be looking in to?
