Leaving aside oil and wheat, we must say that coffee is on the third place in the world as an important traded commodity, and, judging by its quantity, it has the first place in the North American food products import. Moreover, we can describe it as a source of export in the developing countries. At this moment, coffee plantations cover about eleven million hectares of the world’s total area of farms, and approximately twenty million families work in the coffee making industry. That is why, generally, coffee is very important worldwide, found in every home in the world.

After the collecting of coffee crops, its way to the final consumers is very long. Coffee passes through a number of processes and intermediary exporters and, of course, importers. First, it leaves from the producers going to the intermediary exporters, and then to the importers. Next, the roasters, and then the tradesmen handle it; eventually, it arrives to the consumers. Even if it seems a long and difficult way, this is the usual and logical path of the coffee beans, which end up ground and attractively wrapped.

Yet after this long way, once they reach the hundreds of millions of homes, the coffee grounds pass through a last chemical process. Preparing the coffee has never been so easy ever since the development of coffee and espresso machines. Although the first coffee percolators were big and very hard to handle, the development of the coffee machines industry has made their utilization very easy. After the Second World War, the metal parts found their replacements in glass and Pyrex ones, lighter, unbreakable and even more attractive. These changes have brought only favorable appreciations from the consumers, and, in this manner, the industry of coffee machines has been and is still increasing day by day.

Nevertheless, referring a little more to what coffee machines really are, we must say that their basic and most important characteristic is that they work, most of them, on electricity. The electricity generates enough caloric power to heat the water to its boiling point, so that under pressure it can mix automatically with the coffee grounds.

The starting point of coffee machines is the first manual percolator, which worked under high temperatures, developed with the use of fire. The “Biggin", as people had labeled it, had its origins in 18th century France. Of course, the biggest importance in creating a coffee machine is its electrical source, but the materials from which people made it are also important for the maintaining of some industrial standards, which, unfortunately for the producers, develop every year. The temperature of heating, the materials from which people make coffee and espresso machines, the brewing time and the quality of the mixed coffee flavor are the most important characteristics that a consumer should expect.

The usage of both coffee machines and espresso machines bears the influence of the machine’s type and, of course, of the consumers, who come from different cultures and environments. Espresso machines are particularly preferable if you have a taste for stronger and creamier coffee. However, there are coffee makers that, even nowadays, do not use electricity. These are the modern percolators.

Overall, electrical or non-electrical, coffee makers have a very powerful industry that is, as the genuine coffee industry, in a continuous development. Their great utility, low costs and high standards of quality give them a very important place in every home in the world.
