First post here. I'm quite new to the world of single malt whisky, but I can say with absolute certainty that I'll be enjoying it for the remainder of my days. The first scotch I tried was Glenfiddich 12 (was an impulse buy brought on by conversation with a fairly sophisticated coworker) - it was very difficult to drink and I recall making a face. I put it away and didn't touch it again for many months until after I made a friend in a scotch drinker. Now this fellow has a tendency toward inexpensive scotch, so it's a wonder I ever became fond of it, but there's something about drinking with a friend that makes it more enjoyable.
Anyway, it did not take me long to polish off that initial bottle and I was quickly out looking for something else. I have tried only a dozen different single malts and enjoyed every one of them. So back to the original topic, favorites, I am quite fond of Lagavulin 16, Glenmorangie Nectar D'or, Auchentoshan Classic, & The Yamazaki 12. I have much research to complete, but for now it is Glenfarclas 25 that tops my list. I look forward to trying many more single malts and hope I don't go broke in the process!
