If you're going to do Macallan, you have to spring for the 25 year. It's much better.
It's a lesser known brand, but it's delicious.
Yes, that's absolutely correct. People think Johnnie Walker is top shelf Scotch, but any blend is by definition subpar. They blend in order to obtain a consistent flavor (i.e., single malts can change over the years, just like a wine from different vintages will change). But when you blend, you're necessarily obtaining a more generic flavor that is less distinct and less flavorful. I don't drink blends, unless I'm at a bar and am drinking solely to get drunk (in which case I'll add ice to my Scotch -- otherwise, you drink it neat or not at all).
