As a low-brow whisky nerd, I'd enjoy any of these bottles as a gift.
Bourbon
Woodford Double Oaked - Fancy without being outrageously expensive (~$50). Distinct among normal bourbons in a very, very good way. One of my favorites -- if not my favorite -- right now.
Eagle Rare - Hard to find but nicely priced. Outstanding. Don't know anyone who dislikes it.
TN Whiskey
Dickel Bottled in Bond - 13-year-old, 100-proof goodness.
Jack Daniels Single Barrel - Overpriced but good. Plus, people who aren't whisky dorks will be impressed by the name and bottle.
American Whisky and Rye
Michter's American Whisky - If you find some anywhere near southeast TN, PM me. It just doesn't exist where I live
Knob Creek Cask Strength Rye - Never had this, but their normal rye is great.
Scotch (non-smokey)
Auchentoshan Three Wood - Outstanding, off-the-beaten-path single malt for under $75. Complex but approachable.
Compass Box Oak Cross - Blended malt that's on par with great Speyside single malts. Like the Auchentoshan, a little out of the ordinary. Plus, under ~$55.
Scotch (smokey)
Compass Box Peat Monster - Blended malt for Islay fans that are looking for something a little different.
Laphroaig 10 cask strength - Briney smoke bomb for the true believers.
Irish
Redbreast 12 - Awesome, true-to-style single-pot-still Irish whisky for under ~$60.
Green Spot - Single pot still Irish whisky that's got a little more fruit going on than typical Irish stuff.
Happy shopping, dude. A nice whisky is always a great gift.
