I have 250 of 60w, 75w & 100w, plus spotlights/floods etc, all in incandescent bulbs. None of those CFLs for me.
I buy Dunkin’ Donuts or Eight ‘o Clock Whole Bean brands ($5.99-6.99/lb), grind it to Turkish consistency in-store, for fullest flavor, but don’t stock it in prep supplies. Once ground, unless refrigerated, it just goes stale. I can get along wo/ it in a SHTF. But I do the Whole Bean-Turkish grind for 1-2 lbs/ weekly, for ‘fridge/freezer storage. If you regrind pre-ground coffees to Turkish (expose more surface area to H2O), they taste much better, IMO.
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.
