espresso v coffee

the difference between espresso and regular brew coffee is the amount of time that the hot water is in contact with the beans. regular coffee is brewed at a lower temperature than espresso, with more water and for a longer period of time (typically for at least one minute). espresso is concocted through a high-pressure process that involves forcing steam through tightly packed and finely ground beans for about 25-seconds at 15 atmospheres (ATM) of pressure . the caffeine content of both brews is determined by the amount of time that the beans are in contact with water and the roast of the bean. as a general rule-of-thumb, espresso has anywhere from 1/2 to 2/3rds as much caffeine as a cup of coffee.

oh, and it's espresso not expresso, you hoosier.

this diagram might help you prepare for your next starbucks date... but you'll still have to get the tall-grande-venti thing down.
