Jack Daniel's isn't bourbon.
Jim Beam only technically so.
Jack Daniel's is made in Tennessee. For a whiskey to be called "Bourbon," it must come from a designated area in Kentucky, of a certain water, a certain specific content and aging process. So Jack Daniel's is simply whiskey.
Maybe you might like to try a rye? I don't know about your area, but Old Overholt is about the only Rye available around here. You may have better luck. Once common (in the US), Rye is a somewhat unusual find on the shelf these days. Good Rye is worth the hunt.
My own taste is for Maker's Mark. Also some excellent Scotch and Irish whiskies - I inherited a bottle of Glenmorangie that I have about finished off.
