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.
I dont like my coffee sweet, black coffee smells so good anyways.
Though every once in a while (super rare) when I feel like treating myself I will have coffee splashed with a bit of vanilla oat milk.
