The stimulant caffeine bears the scientific name xanthine alkaloid, and it is found in tea leaves as well as in coffee beans. Today, adults drink more coffee than most other beverages on a worldwide basis, because coffee enhances the drinker's mental awareness of the world around him and stimulates the body to better complete the activities that the day brings.

Home coffee makers and espresso makers. Coffee makers are generally one of two types, coffee brewers or espresso machines. Espresso machines are favorites of true coffee lovers because they instantly produce fresh, strong coffee.

An espresso machine can come in lots of different sizes: you can buy a small one for your home, or watch a barista use a larger machine in a coffee shop. These machines all do basically the same thing: they shoot streams of hot water through concentrated ground coffee, and the end result is a tiny shot of frothy espresso.

Some people simply drink the espresso shot, but others sweeten it with milks or creamers. It's all a matter of personal preference. If you want the authentic taste of professionally brewed coffee, opt for the espresso machine. The coffee produced by traditional coffee brewers simply put out a diluted version of espresso. If you want a tamer flavor without having to add cream then a coffee brewing machine is all right, but the real genuine coffee taste will always come from an espresso machine.

Different Espresso Types - Each of the various different types of espresso machines will make an espresso of differing intensity and flavor. Over the years, though, espresso has become the base ingredient of high-quality coffee.
