West Cork Bourbon Cask Whiskey
Whisper it, because if they hear you they'll jack up the price—this stuff is excellent. Rich, sweet, spicy, smooth, and a wonderfully wide, buttery mouthfeel for something in this price range, and frankly better than lots of stuff that costs 2-3x as much. At the very least, it absolutely beats the snot out of any of the standard mass-produced bourbons or ryes one can generally find in the UK, which again are almost always more expensive than this. It's not particularly subtle ... but it's delicious.
