My mom always took her coffee black, so did my grandma, so I think it imparted onto me. For me I like the bitterness, when I take a sip of my morning coffee and it hits there's nothing like it.
Over the years I've tried to get into sugared coffees and I still keep coming back to black. Although every now and then iced coffee with creamer and sugar is a good treat.
Actually good coffee. Drank the cheapest and nastiest coffee, had to use sugar and salt to make it palatable. When i first visited Cuba, i got a coffee not long after i got off the plane. The difference is night and day. Also, instead of energy drinks, i just had a shot of nasty espressor and a cold bottle of water to wake me up on the night shifts.
