Espresso Machine Buying Guide

Choosing between Manual, Semi-Automatic or Super-Automatic

Purchasing an espresso machine can be a substantial investment and requires some important decisions. IDC is committed to helping you make the right choice to meet your needs, lifestyle and budget. We are here to answer any questions you may have or to make suggestions if required. Please review our buying guide below for some general considerations to keep in mind when choosing an espresso machine.

General types of espresso machines

First, we suggest that you read our article on the types of espresso machines; this will give you a better understanding of the general types of machines that will be discussed.

Are you a person who relishes detail? Someone who wants to be a part of espresso extraction process? Someone who appreciates the finer things in life and understands that art takes time and effort? Then a manual piston driven machine might be the choice for you.

Manual machines…do the pros outweigh the cons?

Manual machines offer the operator the most control over the extraction process and are capable of producing the finest shots of espresso when operated by a skilled Batista. Manual machines are works of art in themselves, they are often made of polished steel, brass or copper; they stand perched decorating your counter top begging to be admired and discussed. Although not commonly used today IDC is respectful of the history of espresso and we do carry some manual machines for the romantics.

The most common espresso machine is some form of semi-automatic. These machines are named such because they have an electric pump that creates the pressure required for a pull of espresso. Semi-automatic machines are also for people who also want more control over their coffee but like the convenience of not having to pull on a lever to create the water pressure. Whereas fully automatic machines take this one step further and also automate the extraction process.

Don’t underestimate importance of your coffee grinder

Another very important consideration when purchasing a manual, semi or fully automatic machine is the grinder. Espresso requires finely ground coffee and a decent grinder is an important consideration. Coffee grinders are divided into two types. The first is blade grinders which have two or more blades that rapidly and repeatedly chop the coffee beans into a powder. The downside to blade grinders is inconsistency and heat transfer and the upside is that they are relatively inexpensive. The second type of coffee grinder is a burr grinder. A burr mill or burr grinder is a device to grind hard, small food products between two revolving abrasive surfaces separated by a distance usually set by the user. Burr mills do not heat the ground product by friction as much as blade grinders, and produce particles of a uniform size determined by the separation between the grinding surfaces. High end burr grinders are remarkably consistent in the grinds they produce and feature a wide array of settings from coarse to very fine.

Grind beans just prior to brewing for maximum freshness.

Are you a person who is in a hurry? Someone who just wants great coffee in the morning and wants it fast and easy? Then a super-automatic is the machine for you. A super-automatic machine only requires you to fill the bean hopper and the water tank and then press a button to extract a shot of espresso. The machine will grind the beans, tamper the coffee, and pull the shot for you in a matter of seconds. Now, there are even some high end super-automatics that have a milk reservoir that can foam milk automatically and create cafe lattes, cappuccinos or cafe macchiatos with the press of a single button.

To summarize we have included a chart below to illustrate the steps required to create given types of coffee drinks using the different types of machines.
