Lately I've also started on bourbon, I find I really like Jim Beam Black. As a bourbon corner sewer, do you have any other recommendations?In my opinion, (and this is just my opinion), there are several bourbons that should be on any bar cart, in o particular order.
Wild Turkey 101. Don't laugh. It's a lot better bourbon than most people give it credit for being. Hereabouts, I get it for about $20 a bottle. At 101 proof, it mixes well with cola, or it can be consumed neat, or with ice. Really a very versatile mixing bourbon at an economy price point.
Evan Williams Bottled in Bond. It's a four-year old bourbon bottled at 100 proof. Very versatile mixer, also good neat (although I drink it with Diet Coke).
Buffalo Trace. Originally, the Buffalo Trace distillery didn't have a signature bourbon, making a variety of brands, but the resurgence of bourbon made them re-thing that option. Nowadays, Buffalo Trace bourbon is a very nice, nearly upscale bourbon at a very attractive price point (mid -20s hereabout). I like it neat, or with just a single ice cube.
Maker's Mark. It's a wheated bourbon that I like to drink neat. But, the make a variety they call Makers 46 that I am currently exploring. Very nicely finished, a small step up from the basic Makers, and not overly expensive.
Those four should be on every shelf. After that, the sky is the limit. Buffalo Trace makes a bottom shelf that they call Benchmark. Great mixing whiskey. They also make the Weller's line, an upscale ($50-ish) that is very nice in a couple of varieties.
Elija Craig Small Batch is a favorite, as is Jack Daniels, (not technically a bourbon, but I quibble). I also like Knob Creek (we really love sucking the Knob), and Bullit. I recently bought a bottle of Four Roses Small Batch, and I'm having fun exploring that bottle.
That should give you a starting point, but those first four should be in any collection, and won't break the bank.
