Crema - The stamp of quality

In espresso making, actually in coffee making in general, it can become one of those subjects where it can be hard to tell if and what good coffee is. Espresso, however, has something that your eyes can take notice of in order to make a judgement, "is this espresso or espresso-tastic?" Say hello to crema.

Crema simply observed is the lighter colored foam that naturally appears on top of the espresso (no to be confused with the milk foam that is poured in for a latte). It's the carbon dioxide and other bits of coffee science that come together to form a Guiness like head on the espresso, not too dark, not too light, it is the sign of a great shot of espresso. Now I know in the US most people don't drink it straight, but if you get a good one...well, lets just say it's the ultimate pure coffee experience.
