I know that the caffeine in coffee comes from coffee beans. But where does it come from when its found in Coke, Pepsi, and other soft drinks?

I've seen those signs that say "We proudly serve Starbucks Coffee"... If I buy coffee beans from Starbucks, then can I legally sell coffee in my shop saying that it is from Starbucks? Or is that against the law?

I would assume I'd have to ground the coffee beans very finely....

like on a machine.
I cant make it that well.And i dont know what the difference between latte, cappuccino, espresso is I mean we use the same coffee beans and milk!

I've heard it doesn't work or it just leaves a different flavor than regular espresso. Which is true?

If you can't, how much (generally) do whole coffee beans cost? how much would a very cheap grinder be? Or how much would it cost to buy pre-ground espresso coffee?

I just got an espresso machine and i dont know what to put in it. Are there special espresso beans to use with it or are you supposed to use coffee beans? I've been using foldgers and it doesnt taste stong enough.

I have never had a coffee grinder, but I have coffee beans. I want to be able to grind them, but I do not know what coffee grinder to buy. I can't spend very much on it - I am hoping that there is a good coffee grinder for around . I am hoping to be able to buy one with more than one setting.

So I got a new cappuccino machine for Christmas and I'm not sure what kind of coffee beans to get. Do I get espresso or what???? I have no clue what I'm doing (as if you couldn't tell!!!) so if anyone could please help me out!!!

I want to make my own energy drinks, and I want to know how to extract caffeine from coffee beans or sugar cane, either one is fine. I want to know of a way I could do that and be able to put caffeine into a drink. Thank you.

I want to buy a cappuccino/espresso machine but I am not familiar with how to make it. I wanted to know if there are a certain type and/or consistency of beans to get? If you live in Maryland, let me know where I can buy these coffee beans. Any help would be appreciated.
