Personally: black.
I drink it black without sugar and milk, i like to enjoy the true aroma of coffee. Last week i drink one of the best coffee in the world on a special barista they use a method which only 2 places know in the World rn. It was very amazing.
But at home everyday 1 little cup black without sugar and milk. I dont like coffee, my aim is so jittery and i am talking so much if i drink coffee.
