What is the difference between espresso and drip coffee

Coffee?, Espresso? What's the difference???

There are two main differences between espresso coffee and drip coffee: the fineness of the grind and the brewing time, being finer the grind for the espresso and shorter the brewing, being that possible since the espresso machines generate high pressure (15 atmospheres) to force water through the coffee.

A shot of espresso is made forcing almost boiling water through tightly packed, finely ground espresso coffee. The result is a dark brown, slightly thick liquid with a small amount of foam, called cream, on top.

Espresso coffee es made from a blend of several types of beans roasted until dark and oily looking.

The beans are ground much finely than for drip coffee, almost to the consistence of powdered sugar. The finer the beans are ground, the slower the espresso comes out. Generally, for the best espresso, it should take around 25 seconds fot the water to pass through coffee.

Drip coffee, on the other hand, is made by dripping boiling water over ground coffee (more coarsely ground, it is), The cater filters through the coffee and gets to a pot. The process is slower than the espresso process.

An apparent strange fact is that a cup of drip coffee has more caffeine than a shot of espresso.

Some of the variables involved in making a shot of espresso are the temperature of water, the pressure of water, the fineness of the ground coffee and how tightly packed the coffee is.
