Often used interchangeably with the more general term syzygy, this dipody involves the substitution of two normal feet, usually iambs or trochees, under a more powerful beat, so that a galloping or rolling rhythm results. See iamb, meter, rhythm, and trochee.
The most important difference between coffee and espresso comes during the brewing process. Espresso is made by forcing hot water through a compressed puck of finely ground coffee at high pressure. This process produces an intensely flavored viscous shot of coffee topped with a lighter-colored foam called the crema.
Espresso is a way of brewing coffee, not a way of roasting coffee. Most people assume that espresso is a kind of a roast. It is not. You can use any roast to make espresso. However, the espresso drink comes out better with darker roasts (but not too dark).
