I highly reccomend Chuck Cowdery's book Bourbon Straight if you enjoy reading. It has a great history of Bourbon and many of the distilleries that are still around today. At the end of the book it offers many different "tast groupings" that help to contrast mash bills. It also follows a "bottle" up the shelf so you can compare a product as it ages or is subject to tighter selection requirements which is interesting.
I have found that my purchases go up and down the shelves depending on my available income more than the available selection!
I have been able to pick up some nice bottles that were not expensive, but because of the information on this board, I learned they were limited or no longer being produced.
I have been searching for an affordable "everyday" pour for myself, but still managed here and there to pick up a top shelf bottle to try or save for a later date.
One of the best tips I have received was not to give up on a bottle after one pour, my taste changes depending on my mood, what I have had to eat or drink prior to a taste, more than I would have guessed.
This is an incredible site, and the people here have been awesome in helping my education and selection.
Welcome and enjoy!
