I have espresso coffee. But I want to know how do you make it strong enough for the extra caffeine. Like when you go to Starbucks and you order an "add a shot" to your frappuccino.
I have an espresso machine already. I'm curious to know about the "added shot" It's obviously a small amount that's packed with caffeine. So, how do they get the small amount without losing the caffeine?

To do it right you need an espresso machine.

The water is forced through at high pressure. You cant really duplicate it without the machine/

GO to starbucks or dunkin donuts lol and just order one.. its a lot easier that turning on ur cpu, logging into yahoo! answers, clicking on ask., and typing up this question! =) i think its like impossible to be made from scratch lol

you need the machine to make it. that's all i know. hey can you please help me answer my Q its about that Fiji water I keep buying!
