I've been drinking Maxwell House for the last 50 yrs. Its what Im used to. Probaby about 12 cups a day. I usually buy their columbian, if available.
My grandparents had a virtual coffee pot when i was a kid. Didn't matter, day or night, there was always a pot on the cookstove or on the gas stove. Everybody always would hang out there, so someone would fill a bunch of cups on a tray and bring them to the living room. Originally, I used cream and sugar. But there, you had to get up and go back to the kitchen for that. The rule there, was 'Move your feet, Lose your seat' So I soon learned to drink it black.
I like our local McDonalds coffee. At others, not so much. I would guess it is the same blend, so I blame the water.
I have a friend who roasts and grinds coffee. All of it I have tried has been good. I don't buy much of it because of the cost with the amount I drink.
