I don't remember my grandmothers' coffees, I was too young and envy those of you who can remember such sweetness.
My mother's coffee (also long passed) was either from an aluminum percolator set on the stove and perked until some arbitrary time and then poured. Always black as I remember. Her more recent brews and the ones that I am personally aware of were from a Corning Ware electric percolator and usually quite bitter. One of my favorite memories as a kid was the 'job' of opening the coffee can. A key found on the bottom of the can was broken off of its soldered-on attachment and then used to unwind the band of metal that connected the can from the lid. The first breaking of the seal released the most wonderful aroma! Folgers, was the usual brand. I finally began to appreciate coffee as a young adult at coffee houses around my university campus. I remember the music (folk) and the coffee as about equal in quality, i.e. excellent!!
I avoid Starbucks at all costs due to the bitter and always burned beans. Why can't they learn to roast them? Friends don't let friends drink Starbucks!
