Funny you say that, I've only recently ventured into the world of bourbon - maybe 5 or 6 months ago - and I'm very impressed with what I've found.
Prices are all a bit over the place in the UK for both Scotch and Bourbon - it's a lot more expensive for us that it is for you, for example an Ardbog was £80 and you guys are paying $80 (so it's like us paying $100-$120). I suppose that relativity and living costs versus wages.....
For the same price as a bottle of good Scotch I can get an outstanding Bourbon.
I don't really feel that I'm in a position to judge yet as my experience is just too limited but I currently have open an Eagle Rare 10yo Single Barrel and a Weller 12yo. Both of these I find very easy to drink, very smooth and packed full of flavour.
I've also have Woodford Reserve Maker's 46 (very, very good) and a couple of Rye's (Rittenhouse 100 was one I enjoyed). All told I'm really nailing the American over Scotch at the moment and finding it much more rewarding flavour/£ wise.
Luckily I've got into it at the right time of the year as I've got my pre-order in for the Buffalo Trace Antiques - Sazerac 18yo, Eagle Rare 17yo and a George T Stagg.....can't wait for these bad boys!!
I'll keep you posted on my journey and when some front-runners come out I'll let you know.
