A Matter of Taste
Guys, in all fairness, nobody knows this gentleman's palate other than himself. That said, can we really make recommendations on anything other than the facts we already know? If the guy likes Glenlivet 12, get him a few bottles of that. Anything more would be a guess! Better yet, why not spend some quality time with dad and take a trip to the liquor store together?
I don't want to step on any toes here, because I value your opinions, but we are only speaking based on what we like. If we all had the same tastes in whisky, a lot of distillers would be closed! Viva Variety!
