My recommendation is to be a star and get something a bit out-of-the ordinary. Go to a liquor store (BevMo or Total Wine has a great selection). I am a fan of scotches from the Speyside region of Scotland. Look for names like:
Balvenie - Their "Doublewood" is aged first in flamed oak, then transferred to Sherry casks for final maturity. It is lovely and will cost you about $50.
Glenfarclas - Anything they distill is marvelous. Heavily sherried flavor and my personal favorite. Cost probably starts about $70.
MacCallan is a well known distiller, but heads above the commonplace Glenfarclas or Glenlivit. You can't go wrong with this Scotch. Cost $60+
My new favorite is Abelour, after taking a four hour tour of the distillery last year. They have a sherry finished malt as well as one that is finished in bourbon casks.
You may come across a variety of scotches from the island of Islay (pronounced "Eye -Lah"). The Islays have a following, but they are not for the faint-hearted. Popular Islays include Bowmar, Lagavulin, & Laphroig. They are very smoky with a distinct flovour of peat and iodine. I have never been a fan and re-gifted a $90 bottle recently.
For something light-bodied, I'd go with a Dalwhinnie or Cragenmore. The Crag is quite lovely.
Glenrothies is very nice in its small round bottle. It has nodes of vanilla, something unusual for single malt scotch.
Glenmorangie has an incredible selection of malts all aged in various woods, including Madera and Claret. I would never turn down a Glenmorangie (pronounced Glen MORANGIE - It rhymes with the word "orangie"). Cost is about $60.
Another interesting scotch from the Isl of Sky is Talisker. It is quite peppery in is flavour, but still quite drinkable.
Believe it or not, you can often find some very nice single malts at Costco and last year I found a fantastic 20 year old malt (re-branded to Kirkland) at $35. It was easily a $100 bottle of scotch.
I am often gifted bottles of scotch. I cringe inside when I'm given a bottle of Johnny Walker "Blue" which cost $165 at Costco and over $200 elsewhere. The intentions are nice, but I would have so much more preferred a Glenfarclas or even a MacCallan at much less money.
Personally I'd forget the Glenfiddich or Glenlivit. Not they are bad scotches, but they are so readily available everywhere aren't unique or special.
Single malt scotches are like wine - each is so different and an adventure. If you stay with a scotch from the Speyside, Highlands or Lowlands regions you can't go wrong. As I said, I'd avoid the malts from Islay.
If you really want to impress your neighbor say the word "SLAINTE" when you hand him the bottle. It is pronounced Slan -Cha with the emphasis on the first syllable. It is the Gaelic equivalent to Salude or L'Chaim.
Now, I believe it is time for a wee dram myself.
