Been a drinker all my life. It's not that I like coffee, I need the caffeine. At Starbuck, I usually get frap. At home in the morning, I drink those instant coffee. So questions: What's the difference between coffee and espresso coffee. I had a conversation once and said, "hey this coffee is good" and the guy said, you mean espresso. Which kind is the strongest as far as caffeine? What's a shot? Is it standardize? A shot of espresso from starbuck is the same as somewhere else. Is a shot of coffee the same as espresso coffee or there's no such thing as a shot of coffee? Call me party pooper but all these fancy names drive me nuts. All I want is my dose of caffeine without the fancy French .
