That’s a good idea - my drip coffee maker chokes on fine grind though.
For long term storage, canned coffee tastes about as good as it ever would, that is, not that great. To get around that, and for the fancy arabica stuff, stashed 30 or 40 pounds of green coffee, beans are easy to roast and the quality is excellent, and green coffee stores for many years.
I got rid of electric coffeemakers many years ago, and use Chemex drip:

I’m looking at a Keurig System...
...but price of entry is steep and per cup costs are 3-5x what I can do w/ Chemex. I can brew better coffee than Keurig or any other maker. Turkish grind is the key to flavor; drip is so much better. And it works in SHTF. Electric makers just become doorstops.
