Some people view coffee drinking as a caffeine-delivery system. Others view it as a pleasure experience. It’s similar to eating being a calorie-delivery system versus a pleasure experience.

I disagree with the conclusion of this article that only a trained barista can make a great cup of coffee. It is accessible to all of us, just like gourmet cooking. It’s all a matter of commitment, learning, equipment, and skill. While I like going out for a great cup of coffee, I also like making one at home.
