Coffeemaker

My wife bought a new coffeemaker which can grind coffee beans a few months ago. My wife and I cherish the coffeemaker and use it habitually. I couldn’t distinguish the difference of coffee beans before I bought the coffeemaker. But I tried some types of coffee beans and I got to find the difference a little bit such as smell, flavor bitter taste. Because of that, I drink a cup of coffee too much lately. I’m happy but a little regretful about the choice of my wife.
