I didn't do it deliberately, but found myself with much more scotch than bourbon as well. The bourbons I could get weren't that interesting, and the interesting ones are impossible to get. Meanwhile there's a treasure trove of great scotch available, with more diversity (if not absolute higher peak of quality) than you could get in bourbon-land anyway.
Shame too. I always used to direct whisk(e) novices towards bourbon because the value was so much higher. Not really the case anymore once you get past $40/bottle or so.
Thats so funny because I moved away from Scotch specifically for the value proposition of Bourbon. Well that and I do actually prefer Bourbon.
Was just in the UK and delighted to find some Nikka From the Barrel @ Waitrose in Marlborough. I love that stuff.
