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.
When I was much younger I did some summers of manual labor and the crew I worked with had a habit of taking in a mouthful of warm water, a spoonful of instant coffee, then shaking your head vigorously before swallowing. I think that focus on coffee as a caffeine delivery drug stuck with me. I enjoy a good cup of coffee but I will drink just about anything as coffee. If I want something that tastes good I prefer tea.
