There are some similar threads to this on the board, but not exactly this particular question. What is it about Bourbon that makes you prefer it? What taste component..etc caused you to prefer it over Scotch...or is it simply economics.
For me I think it is threefold..and I was a Scotch only drinker for a while (still like many Single malts):
1) Economics..at least in the U.S. I can get high quality bourbon for much less than the cost of a good bottle of Scotch.
2) It's Made in America.
3) I went on a diet and cut out dessert pretty much. I discovered that Bourbon really satisfies my sweet tooth. I used to think that Bourbon was one-dimensional..just sweet, but now I feel that frequently it is actually more complex than Scotch. Sometimes the complexity is more subtle and takes some time.
