I used to hate the bitterness in coffee too. Those were the days when coffee was perculated. Once the drip coffee makers came to us, I discovered I liked coffee, it wasn’t bitter. You can make it by the cup or by the pot, and as strong as your heart’s desire.
However, burned coffee is horrid. So, I shut my pot off so that the burner can’t keep cooking the coffee. As a result, each cup tastes as good as that first cup. In the winter, I can reheat the cup in the microwave as long as its not over heated. In summer, I pour it over ice cubes with sweetner and cream and have a refreshing iced coffee. Ummm, delicious!
I do have to watch that evening coffee because then it can give me intense heartburn.
I love K-cups because every cup is fresh-brewed cup. There are a gazillion brands, strengths, flavors available. I like Peet's Major Dickason brand.
