Is a 20 Bar Espresso Machine Good?
There are multiple different factors that are going to come into play whenever you are trying to make an espresso in some way, shape or form. One of these factors is the pressure that you use while creating the espresso at any given point in time. The optimal pressure that needs to be used during espresso brewing is a topic of consistent and constant debate among coffee enthusiasts, and a big part of the reason why that is the case has to do with the fact that the kind of pressure that you decide to use can have a very strong impact on how your espresso would end up tasting once you finish making it.
Suffice it to say that you can buy a wide range of espresso machines from a site like CoffeeShan.com, but you still need to ascertain what the best possible range of pressure might be. The manner in which pressure is calculated uses a unit called bars, and basically the number of bars that your machine is capable of sending your way is calculated by the average atmospheric pressure of the earth itself.
A 20 bar espresso machine can offer up to twenty times the normal atmospheric pressure of our planet, and that is more than enough to create a wonderful crema that is extremely delicious to consume. This crema is a major aspect of what makes espresso so delicious in the first place, so it’s easy to see why so many people want high bar machines that they can utilize. This might be too much pressure for certain beans, though, so try to restrict its usage to beans that will thrive under high pressure.
