Due to the medications I am on for the rest of my life I cannot drink alcohol. Which I do not, for the most part. I have found, that like everything else, a little bit every once in a while is not going to cause me any problems. At least not now. In the future, as my health gets worse, who knows.
Anyway, I do store the liquors and liqueurs that I used to drink occasionally. Once I was making a reasonable amount of money I graduated to the premiums of both types, as well as top-shelf wines. In addition to these, which are for me for the occasional use and for sharing with specific people. I also plan to store long-term-packaged high-grade tobaccos, kept in carefully controlled humidors, with cigarette rolling equipment, cigar rolling equipment, and a large selection of pipes. Also seeds for two to three types of tobacco plus a couple suitable for cigar rolling leaves. If I can, I will have a greenhouse where I can grow coffee beans and cacao beans for chocolate, to supplement canned green coffee beans and plenty of cocoa.
For general trade use, I store Everclear 151 PGA (pure grain alcohol).
The PGA is for medical use, as a disinfectant if nothing else is available, and to make hot toddies when I, or someone else that does not object to having a bit of alcohol. Usually hot lemonade, honey, and a teaspoon or so of the Everclear. Taken with a peppermint disk I find the combination to be very effective in clearing my sinuses and helping me sleep.
And it is a trade good, as well. I have not found it in the 50ml 'airplane' bottles, even plastic ones. So, for trading the Everclear, or any other alcohol I might have or run across, I will transfer it from the 750ml bottles I usually get, to glass 50ml bottles I get on Amazon now. I do try to get the Everclear in glass bottles, but if I cannot find it in glass I go ahead and transfer it from the plastic bottle into the 50ml bottles and seal the caps with wax.
I use 4-ounce to 8-ounce stainless steel flasks for the Everclear I keep in medical kits.
I have found that, while a few high-grade plastic bottles that some bottlers use do not taint the alcohol, not allow for migration through the plastic very quickly, the cheap bottles do. Either one is a deal killer for me. If I cannot get something an original glass bottle I always transfer it to glass and seal the regular cap with wax.
I do not stock much in the way of wines, though I do try to keep a few splits of good Champagne. I can no longer afford vintage Louis Roederer Cristal Champagne, I will occasionally get a split or two of Dom Perignon to have for major celebrations. I also will get Korbel in splits for longer storage since if I cannot have the really good stuff, I do not drink much at all, even when there are reasonable reasons to have something like Champagne.
For beer, wine, and a few other spirits as well as some soft drinks, I plan to acquire the equipment and supplies to make them myself. I am fairly certain there will be plenty of people distilling hard liquor so I do not worry about it overly much.
If I was able to stock in-depth the things I would drink they would be the following:
Root beer making kit using flip-top Virgil’s Root Beer bottles w/spare rings
Beer/stout making kit using flip-top Drake’s Imperial Stout bottles w/spare rings
