Ask any coffee aficionado about espresso and it’s likely he’ll tell you a story rather than a short, straightforward answer. Coffee is available pretty much on every street corner and with Starbucks packing in locations every couple miles, most people see it as a fast caffeine-filled pick-me up, just another drink to help them make it through a long work day. Coffee aficionados, however, know of the nuances among the different types of coffee, understand individual flavor profiles and enjoy a much higher-level drinking experience. Want to join the club of true espresso and coffee enthusiasts? Looking to start brewing your own espresso at home and need some guidance? Allow us to enlighten you on the basics and help put you on the path to espresso nirvana.

Espresso is the type of coffee made by forcing a few ounces of pressurized, nearly boiling water through finely ground coffee beans, producing a cup of coffee characterized chiefly by its concentrated flavor. Espresso’s other distinguishing characteristics are its being thicker in consistency than most of the other types of coffee and its having a creamy foam on top, called a crema, and a higher concentration of solid particles than the others.
While many people believe that espresso is the strongest type of coffee, it isn’t. Although it has more caffeine per unit than most of the other types, due to its usually small serving size, the total caffeine content of a cup of it is less than your regular cup of joe.
Since espresso is the base for several of the other types of coffee, such as cappuccino, caffè latte, caffè Americano, and caffè macchiato, it may also be considered the most popular type. Due in large part to the success of popular coffee shop chains like Starbucks, it’s likely you buy coffee every morning at one of these establishments rather than make some by yourself at home. There’s nothing inherently wrong with buying from a chain shop, since there are now numerous baristas trained in preparing all of the different types of coffee while using high-quality, expensive coffee makers. But you should know that there are now many coffee makers available in the market that enable you to make coffee by yourself at home that is as good as if it were made by a well-trained barista, and these machines continuously increase in number, variety, and quality. If you ask us, a cup of great coffee made right in the comfort of your own home beats the $5 alternative made by even the best barista any day.
To help you learn which type of coffee maker might be the best fir for you and your lifestyle, allow us to discuss the different types, beginning with the various types of espresso coffee makers: steam-driven, piston-driven, pump-driven, air pump-driven, with boiler, stove-top, and automatic.
The first espresso coffee machines were steam-driven. They brewed coffee by forcing a certain amount of water through ground coffee beans using steam or steam pressure generated by a boiler. Steam-driven espresso machines aren’t costly to mass produce, especially since they contain no moving parts, so such espresso machines are still available commercially as low-cost espresso coffee makers.
Piston-driven espresso machines brew coffee by sending pressurized, hot water through ground coffee. These machines do so after being activated by a lever, pumped by an operator. Also referred to as lever-style espresso coffee machines, piston-driven espresso coffee machines require pulling their long handles to make espresso, giving rise to the expression ‘pulling a shot of espresso.’
The 2 types of piston-driven espresso coffee machines are manual and spring. A manual piston-driven espresso coffee machine requires an operator to push a certain amount of water through ground coffee directly in order to produce espresso, while a spring piston-driven espresso coffee machine requires an operator to apply tension to the spring himself in order to deliver the pressure needed to make espresso.
Motor-driven pump espresso coffee machines are generally considered the refined version of piston-driven espresso coffee machines. Instead of manual force, the aforementioned coffee makers’ motor-driven pumps generate the needed force for making espresso. The other distinguishing characteristic of these espresso coffee machines is their ability to take in water directly from either a supply or from a separate water tank. Motor-driven pump espresso coffee machines that can take in water directly from a supply are currently used at most of the coffee shop chains, while motor-driven pump espresso coffee machines that can take in water only from a separate water tank are most commonly used at home.
The 4 different types of motor-driven pump espresso coffee machines are: single boiler (SB), single boiler / dual use (SB/DU), heat exchanger (HX), and dual boiler (DB).
Single-boiler, motor-driven pump espresso coffee machines can only brew coffee, without steam, and that requires only a single boiler for making espresso. These espresso coffee makers are the most uncommon type among the 4 different types of motor-driven pump espresso coffee machines.
While single-boiler, dual-use, motor-driven pump espresso coffee machines each come with a single chamber that enable them to heat water to brewing temperature and boil water for steaming milk, they cannot perform these operations simultaneously. They require a warm-up period between executing an espresso pull and frothing milk, making using them somewhat of a chore to use.
Most heat exchanger, motor-driven pump espresso coffee machines heat the water for brewing by passing it through a ‘heat exchanger’, the part that takes some of the heat emitted by the steam generated during the brewing process without rising to the same temperature. Although the water remains at a lower temperature range than that required for steaming milk, it is still too hot for proper brewing, necessitating 4–6 seconds of cooling before use. Once the said espresso coffee makers are set to the proper temperature, as many shots as required can be pulled; however, if the machines are left unused for several minutes, the flushing process has to be repeated, making using them a bit of a hassle.
Dual-boiler, motor-driven pump espresso coffee machines heat the water for brewing in a separate chamber, which requires two separate boilers. Many believe these coffee makers can generate the needed temperature for brewing in a more stable way than most of the other coffee makers available in the market, but at the expense of steaming performance and speed.
Air pump-driven espresso coffee machines use compressed air to force hot water from a kettle or a thermo flask through ground coffee. The compressed air is generated by a hand-pump, N2 or CO2 cartridges, or an electric compressor.
One of the advantages in using these types of coffee makers is that they are much smaller and lighter than most of the other espresso machines currently available in the market, especially the electric-powered ones. Indeed, most air pump-driven espresso coffee machines are portable and handheld.
Also called Moka pots, stove-top espresso coffee makers are similar to espresso machines in that the former brew under pressure, make coffee with a similar extraction ratio, and produce crema of the same quality, except they do so without any automation.
These coffee makers consist of 3 chambers: the bottom chamber, where the water for brewing is to be poured and contained; the middle chamber, where ground coffee is to be put; and the top chamber, where the coffee ends up after it funnels through the 2 aforementioned chambers while the coffee makers themselves are being heated on a stove top.
Espresso machines that come with grinders, pumps, sensors, and valves for automatic brewing are called automatic espresso machines. There are 3 different types of automatic espresso machines with varying degrees of automation: semi-automatic, automatic, and super-automatic.
Rather than manual force, semi-automatic espresso machines use a pump to deliver the water needed for brewing.
Automatic espresso machines control ‘brewed volume’ automatically by way of an in-line flow meter attached to a grouphead. When the programmed amount of water has passed through an automatic espresso machines’ flow meter, its pump turns off automatically, ending the brewing process. These coffee makers still require manual grinding and tamping of coffee, like the semi-automatic machines.
Super-automatic espresso machines can grind coffee, tamp it, and make espresso all without any interference on your part. The only help these coffee makers need from you is filling their bean hoppers and pouring water into their water tanks. Some models of these machines come with an automated milk frothing and dispensing device, enabling them to make the other types of coffee, besides just espresso.
While automatic coffee grinding and tamping is convenient, many believe doing both manually ensure that proper espresso is produced every time.
Automatic espresso machines are our top pick for the at-home brewer and they now come in a wide variety of designs, sizes, and features, making finding the best one for at-home brewing a little tricky, especially for the novice. To help you, here are 3 that we believe will give you the best possible at home espresso experience:
