Many, many years ago, Maker's Mark had a Gold bourbon, complete with gold wax over the cap. It was really, really nice. They discontinued it, and supposedly replaced it with the 46, not the same in my opinion.
What i am working on right now is my own infinity bottle. I started on it a few months ago with an old crystal decanter my Dad had purchased from a Reserve Barrel about 40 years ago. I am looking forward to sampling the contents after a few more months of filling it.
Regarding Maker's Mark, I am going to be visiting the distillery next Spring. My Dad purchased an entire barrel over 25 years ago, and he never picked it up. It has since been emptied and filled again, awaiting him to get it. Since his ascension over 5 years ago, I have been trying to have it shipped, but they will not, not even to a ATF or State Liquor Authority licensed agent. I have to go there and get it myself. It will be a whole experience though. I will be able to assist in the opening of the barrel, the filling of the bottles, the dipping of the bottles in the wax, and then packing up the bottles into cases for the trip back. I am told between 15 and 20 cases.
