The question of whether it is better to use copper or bronze espresso machines can easily be answered if one realizes that the original versions had both copper and bronze. It just knows which is used where that is important and no, one need not be an Italian to understand this simple rule about espresso machines. For more than hundred years, these rules of making espresso machines have been handed down to us from the time that Italian gentleman Luigi Bezzera first thought up the idea of the Fast Coffee Machines.

Use Of Steam To Brew Coffee

When he first came up with his espresso coffee machines, Luigi Bezzera used steam in order to brew coffee. Then, in 1947 another Italian named Achille Gaggia came up with the invention of brewing coffee under pressure. However, the coffee machine made by Bezzera used big cylcindrical shaped machines that had copper, bronze as well as brass fittings and which closely resembled what can only be called a space ship.

Thus, when considering whether to use copper or bronze espresso machines it is necessary to understand that the secret behind the best espresso coffee is being able to have a process that churns out crema that is nothing but coffee foam of hazelnut color. Thus, you need to remember that you must have the ideal pressure built up in the machine to get you the best espresso coffee, and it means having to choose between copper or bronze espresso machines.

It is normal for the better espresso machines to have steel frames that are wrapped in stainless steel panels and the boiler and piping are generally made from copper, while the fittings are made from bronze. If you must choose between copper or bronze espresso machines you should realize that the better machines have copper used for boilers because of its property of being able to expand and contract much better than other metals. In addition, if you want a machine that has better looks you can choose one that uses bronze on the fittings.

Thus, the answer to copper or bronze espresso machines can easily be found when uses copper for the boiler and bronze for the fittings. That is how the better espresso machines are being made is it the Gaggia Classic or Rancilio Silvia. The difference between these high end espresso machines and the cheaper ones such as Expobar is that the former has a single boiler and can operate at two different temperatures that are brew and steam temperatures. Thus, brewing and steaming are two separate processes, whereas the cheaper machines have one process that includes both brewing and steaming. However, the copper boiler in the cheaper machines were quite good in their performance and were thus quite handy to have in the home irrespective of the fact that they cost less, but were nevertheless symbolic of copper boiler machines and thus were able to overcome the need of having to choose between copper or bronze espresso machines.
