During COVID I couldn’t find any distilled water to make cocktail pods (which are already pretty extra in their own right), so I bought an alembic still and learned how to use it to distill water, which led me to figure out how to rig it up with a hot plate, food grade tubes, fish tank pump, and igloo cooler so I could run it in an out of the way spot in my house. It takes days to make a few gallons…but the cocktail pods came out great and now I’m slightly closer to being a survivalist! (My smartass friends: Why didn’t you just make Jell-O shots?)
"Cocktail pods are small, single-use packets that contain all the ingredients you need to make a specific cocktail. All you have to do is add alcohol and water, and you're ready to go."
I got mine at a beer brewing supply store in Denver. I would guess you could find something similar online. Be sure to wash them well the first time. My first couple gallons of water through them tasted a bit “rubbery.”
