In the past few decades, big chains like Starbucks and Caribou Coffee and cozy, independent coffee shops have become hallmarks of almost every city and town. With this ubiquitousness of artisanal coffee, it would be close to a miracle if you've made it into adulthood without developing a taste for fancy espresso drinks. Seeing as these drinks aren't exactly cheap, and the lines to buy a latte before work are only getting longer, it is very tempting brew espresso at home. However, making espresso is much more complicated than pouring hot water over coffee grinds and the complicated machinery required can be somewhat intimidating. Not to fear. We've put together a step by step decision guide that can guide you your perfect morning caffeine machine. We've also summarized some of the finer points of making espresso at home, so you impress your friends with your barista skills.

What Exactly is Espresso

Despite its popularity, there are still a number of widespread misconceptions about this magical elixir. Espresso is made from the same beans as normal coffee, the difference in the two drinks comes solely from the preparation. When making espresso the beans are normally ground much finer and then compacted or "tamped" to create a dense block of ground coffee. Hot water is then pushed through that coffee at a high pressure. This method concentrates the flavor of the beans into a smaller amount of water, creating a much more intense and robust drink when compared to normal coffee. All of the fancy cafe drinks like lattes and cappuccinos are created by adding hot milk that has been frothed to create various amounts of foam to the espresso.

Choosing the Right Espresso Machine

Step 1: Convenience or Quality? Super-Automatic vs. Semi-Automatic

The biggest decision to make is whether to go with a super automatic or a semi-automatic machine. The basic difference between these two categories is that super-automatic machines are foolproof and do everything automatically at the touch of a button, while semi-automatic machines require you to grind and tamp (think press into a tightly packed hockey puck) the coffee yourself.

Super-automatic machines are for those that place a premium on convenience and just want an easy, no fuss way to make espresso at home. With their single button functionality adding one of these machines to your morning routine takes zero extra brain power. Also, if you have guests you can generally teach them to use the machine in under a minute. The sacrifice you make here is taste. We found that while super-automatic machines can brew some pretty good espresso, they often tended to water it down a bit and couldn't match the rich, full-bodied shots we were able to pull from semi-automatic models. Bottom line: these machines are quick, easy, and even tasty, but they're not going to match the quality of your favorite Starbucks order.

Super-automatic machines only require you to toss bean into the bean hopper  then they grind  tamps  and brew for you.

Semi-automatic machines require a bit more labor and have a small but not insignificant learning curve when compared to their super automatic brethren. With these machines, you grind the coffee yourself, put it into a portafilter (that fancy, ice cream scoop looking thing you see baristas flinging around), compact the grinds by pressing them down with a tamper, clamp the portafilter into the espresso machine, press a button, and wait for the brew. This may sound complicated, but if watch it all happen in the video below you'll see that it's fairly simple. It might take pulling 10-20 shots to feel proficient in all of these new skills, but it quickly becomes second nature. We've found that if you invest in a nice semi-automatic machine like the Breville Barista Express, this extra effort will reward you with much better tasting espresso. Semi-automatic machines also give you the option of experimenting with grind size, and the amount of coffee used, so you can play around with the subtleties of espresso. These machines are thus better for those that don't mind putting in more effort in order to improve taste and those that enjoy the ritual of coffee making.

Step 2: To Pod or Not to Pod, is Nespresso Right For You?

Nespresso machines fall within the super-automatic genre and utilize a single serving capsule system, similar to the Keurig coffee makers that have become common in many offices and the waiting rooms of overpriced dentists. These capsules, often referred to as pods, nearly eliminate cleanup and make it easy to quickly switch between types of coffee. Their biggest obvious downside is cost. Making a shot with one of these capsules can be as much as double the cost of making a shot from freshly ground beans.

Aren't Those Capsules Bad For the Environment?

On top of the extra cost, many users will be concerned about the environmental impact of producing all those little capsules. Nespresso does offer a free recycling service for the Capsules. However it is not clear how many users participate in this recycling program, so some people feel that buying into this capsule system is buying into a system of unnecessary waste. Additionally, recycling is not a 100% efficient process, so it is still better to not produce the recyclable waste in the first place (that's why 'recycle' come after 'reduce' and 'reuse') The Guardian recently published an article that called out Nespresso's lack of transparency in reporting how many capsules get recycled. The good news is that same article lauds Nespresso's efforts in responsibly and sustainably sourcing their coffee. Additionally, Nespresso has said they are committed to making their capsules more sustainable.

Capsules are convenient and require hardly any cleanup  but they're expensive and create a lot more waste.

The greener alternative to Nespresso is a super-automatic machine that you put your own beans in, like the Gaggia Brera. All you have to do is put whole beans in these machines and they will grind and tamp them automatically. This ends up being nearly as convenient as a Nespresso machine, with just a little additional cleanup (since you'll have to rinse the bin where the spent grinds are deposited). Since you can choose your beans for these machines you can make sure you're drinking an ethically and sustainably sourced brew, without having to worry about buying into a system that wastes a bunch of aluminum.

Step 3: Got Milk?

If straight shots of espresso isn't your thing, you'll probably be looking to add milk with varying degrees of frothiness to create lattes and cappuccinos. This requires some sort of milk frothing device. The machines we reviewed ranged from having built-in, automatic milk frothers (Gaggia Anima Prestige) to having cafe style steam wand (Breville Barista Express) to having no way to froth or steam milk (Nespresso Inissia).

A good steam wand  like the one on the Breville Barista Express  makes the  best steamed milk. However  they require some practice  and can get pretty gunky if you're not adamant about wiping them off after each use.

Nespresso machines are the most likely to not includes a milk frothing device (the De'Longhi Nespresso Lattissima Pro being an exception). This can be remedied by buying a standalone milk frother like the Epica Automatic Electric Milk Frother or the Nespresso Aeroccino Plus Milk Frother. However, these frothers require some scrubbing and cleaning after each use. While this isn't particularly arduous it felt like it really detracted from the convenience of pod capsule machines.

Automatic milk frother is a nice addition to a capsule machine. However  the added cleanup bogs down an otherwise cleanup free process.

In general, we found machines with built-in automatic frothers the easiest to use. Stand Alone milk frothers are also easy to use, but slightly harder to clean. Steam wands produced the best milk in our testing, but definitely required the most effort and had a bit of a learning curve. However, if you want anything close to latte art quality milk you'll have to use a steam wand. For a more in-depth review of frothers, see the 'Which Milk Device do You Want?' section below.

Step 4: Consider Ease of Cleaning

Cleaning will probably be your least favorite part about owning an espresso machine. In our ease of cleaning metric, we've evaluated everything from day to day cleaning requirements, like emptying drip trays and wiping down steam wands, to long-term cleaning processes like descaling (which flushes out mineral buildup). Descaling is generally only done every few months (depending on usage and how hard your water is), so it should factor into your decision less than daily cleaning.

Generally, we found models that use capsules, like the Nespresso Inissia to be the easiest to clean when making straight espresso, but adding in a separate milk frother to make cappuccinos increased cleanup significantly. If you want to add milk to your drink, super automatic models like the Gaggia Anima Prestige, which have built-in automatic milk frothers, were the most painless to clean in our testing. Just make a few drinks and then throw the milk frother into the dishwasher.

Step 5: Don't Forget a Coffee Grinder

Most of the models we tested either have a built-in grinder or use capsules that negate the need for grinding (the Mr. Coffee being the one exception). If you end up going with a machine that doesn't include a grinder, you'll need to get one. Espresso tastes much better with freshly ground beans. You won't want to skimp on the grinder either, as a sub-par grind will make poor tasting espresso, no matter how good of a machine you have. We would recommend a quality burr grinder, like the Oxo On Barista Brain.

Types of Espresso Machines

A number of different methods have been developed to create the high pressures required to extract a perfect shot of espresso. However, these different methods represent a wide range of success and complexity.

Stovetop Espresso Makers

Stovetop makers, sometimes referred to as Moka pots, are essentially fancy kettles. They have a lower chamber that is filled with water and then put on the stove. When this water boils the steam is pushed up through a layer of ground coffee and then through a small tube into the upper chamber. These makers can't produce the same kinds of pressure as machines, and many aficionados would consider what they produce as strong coffee rather than proper espresso.

Manual Espresso Makers

Manual espresso makers generally require water to be heated separately and then added to the machine. Then, human power and a lever or some other mechanical device are used to create the proper brewing pressure. These devices range from large and stationary to small enough to bring on a camping trip. Some of these makers can produce decent shots, but since you're the one applying the pressure it can be hard to maintain consistency and they often come with a steep learning curve.

Semi-Automatic Espresso Machines

Proper espresso machines use a pump to create the require brewing pressure and are much more consistent and effective than any other method. Semi-automatic machines use pumps to automatically create pressure, but still require you to do some things manually like grinding and tamping the beans. These machines have a bit of a learning curve, but we found the nice ones produce the best shots of any machine type.

Super-Automatic Espresso Machines

Super-automatic machines do everything for you. All you do is put some beans in a hopper and the machine automatically does all of the grinding, tamping, and brewing. Some machines even have built-in milk frothers and can make a cappuccino, all at the push of a button. We found that these machines generally represent a small sacrifice in taste when compared to semi-automatic machines, but are much more convenient.

Single Serving Capsule Espresso Machines

Capsule espresso machines are a type of super automatic machine, but instead of grinding beans they use pre-ground beans that come in airtight, aluminum capsules. These machines are even more convenient because they require less cleanup, but the capsules tend to cost significantly more than fresh coffee beans. Nespresso machines are the main contenders in this category.

Which Milk Device do You Want?

For those of us that are trying to recreate one of those heavenly coffee shop drinks at home, milk quality is just as important as espresso quality. Before we get into the different types of milk prep devices it is worth reviewing the difference between steamed milk and frothed milk, the two types of milk used in espresso beverages. Steamed milk is essentially heated milk that has had a small amount of air introduced to create a creamy texture and a hint of sweetness, ideally with just a little bit of foam on top. Steamed milk is a key ingredient in lattes and is responsible for the leaves and hearts your barista creates on the top of your drink. Frothed milk, on the other hand, has had much more air introduced in order to create a velvety milk foam. Frothed milk is the very foamy layer on the top of a cappuccino that has adorned many a mustache.

Steam Wand

Steam wands are the most capable milk preppers of the espresso drink world. They can both create the luscious texture of steamed milk and blast in more air to create voluminous and luxurious milk foam. Steam wands are also the most difficult milk tools to use. They require you put the wand into a small pitcher of milk and skillfully move the pitcher around to get the desired result. There is a small learning curve to this, but with some practice, you can get barista level results from some home machines. Also, prepping milk with a steam wand is a hands-on process from start to finish, as opposed to other processes that just require pushing a button. If you're diligent about purging and wiping off the steam wand between each use cleaning is fairly easy, but if you forget a couple of times a stubborn buildup of gunk can form relatively quickly. Below is a helpful video detailing how to prepare milk with a steam wand.

Milk Frother

Stand-alone electric milk frothers boast a very convenient 'pour milk push button' functionality, and they excel at making fluffy milk foam. Most also have a heating function that aims to create steamed milk, but sometimes it is difficult to get that little bit of foam on top of the steamed milk that makes the perfect latte. Also, the little metal coil used to froth the milk can be a bit of a pain to clean.

Automatic Milk Frother

Some of the machines we tested have built-in, automatic milk frothers. These devices automatically heat and frother the right amount of milk for the drink you want and mix it with the espresso, all at the push of a button. These frothers are about as easy to clean as stand-alone models, but most have a large milk tank that can be removed from the larger machine and stored in the fridge, negating the need for cleaning after each use. These machines are definitely the easiest, most convenient way to prepare milk. The one downside: like stand-alone milk frothers they often can't make the steamed milk with just a hint of foam that you'd want for a latte, so you make a small sacrifice in texture.

Automatic milk frothers  like the one on the De'Longhi Nespresso Lattissima Pro  are the quickest and easiest way to a cappuccino.

What's the Deal With Those $4000 Machines?

The most expensive machine we tested lists for $1100, but you can easily spend $4000 and even $10,000 on an espresso machine. You might be wondering what you gain from spending the extra dough. Perhaps the most obvious is a better pump. A better pump does not create more pressure but can create the perfect amount of water pressure more consistently, and that consistency translates into the quality of the shots being pulled (that being said, we were quite impressed with the consistency of the Breville Barista Express).

The biggest difference, however, is that these machines generally utilize a dual boiler system. One boiler is kept at optimum espresso making temperature, while the other is kept right at boiling to supply the steam wand. This means you can pull a shot and steam milk simultaneously, whereas a cheaper machine would have to pull the shot, quickly ramp up the heat to create steam, and then steam the milk. Technically the faster milk is added to espresso the better and fresher it will taste, so this is a distinct advantage, but we were still quite happy with the milk drinks made in the machines we tested.

Finally, all of these expensive machines are geared towards professionals that want to serve coffee to customers and thus are all semi-automatic. If you're willing to spend a lot, want the absolute best, and want to learn the ways of the barista, one of these more expensive machines may work for you. However, we feel their slight advantages will not be worth the large additional cost to most consumers, and that the machines we tested are more than adequate for a good at homebrew.

Espresso Lingo and Terminology: Sound Like a Pro

The world of espresso brings with it a mountain of jargon that can be intimidating even to coffee drinking veterans, whether you're researching what machine to buy or just trying to put in an order at your local cafe. We've compiled some of the most common terms here to make your path from novice to home brewing barista master a little bit easier.

Espresso Making Terms


Tamping refers to pushing down on the ground coffee beans to create the dense block needed to make espresso, The small, circular press used to do this is called a tamper.


A portafilter looks kind of like an ice cream scoop. It has a handle and a circular basket where ground coffee is inserted and then tamped. The portafilter then locks into the espresso machine for brewing.

Filter Basket

Filter baskets are small filters that are placed within the portafilter. Depending on how much or what type of espresso you're making, some semi-automatic machines come with different filter baskets for different situations.

Espresso Terms


Crema is the light brown, slightly foamy layer that appears at the top of a freshly brewed espresso shot. This is often lauded as a sign of a great shot as it indicates fresh beans with a good content of fats and oils. This is true if it is proper crema, which is the result of CO2 outgassing from the beans (which only occurs if they've been freshly roasted) and emulsification of the fats and oils (a high fat and oil content is indicative of beans that were roasted properly). However, many others claim that a crema-like layer of foam can be created by a number of different variables, and therefore is not a definite indication of quality. Regardless of its origins, many people enjoy the texture that is added from this foamy top layer.

Steamed vs. Frothed Milk

Steamed milk is essentially hot milk. When prepared correctly a small amount of air is introduced into the milk that creates a creamier texture and adds a hint of sweetness. Most say that perfectly steamed milk will also have just a tiny bit of foam on top (this foam is responsible for the hearts and leaves your barista creates on top of your latte).

Frothed milk, on the other hand, has had much more air introduced into it, creating a rich and fluffy foam (think the top of a cappuccino). The smaller the bubbles are the richer the foam. In fact, many aficionados refer to high quality frothed milk as microfoam.

Most espresso milk drinks have a combination of steamed and frothed milk. For example, a classic cappuccino is ⅓ espresso, ⅓ steamed milk, and ⅓ frothed milk (foam).

Types of Espresso and Espresso Drinks

Espresso itself can be prepared in a number of different ways, each providing subtle differences in taste and texture. Adding different types and amounts of frothed or steamed milk creates we whole slew of other drinks. A quick visual reference can be found here, but we'll give a quick rundown so you can get the terminology right.
  • Single shot: one shot of espresso, normally about 1 fluid ounce
  • Doppio: refers to a double shot, or about 2 fluid ounces of espresso, most milk drinks use a double shot
  • Ristretto: a slightly more concentrated shot of espresso, usually around ⅔ of a fluid ounce
  • Lungo: also referred to as a long shot, a slightly watered down shot that is about 2 fluid ounces but uses the same amount of coffee beans as a single shot
  • Americano: 2 ounces of espresso (double shot), 3 ounces of hot water, essentially waters the espresso down to have the texture of a normal cup of coffee
  • Cappuccino: 2 ounces of espresso, 2 ounces of steamed milk, 2 ounces of foamed milk
  • Latte: 2 ounces of espresso, 10 ounces of steamed milk, just a bit of milk foam


Home espresso machines vary widely, and choosing the right one largely comes down to a tradeoff between quality and convenience. You can get a machine that will pull a good shot at the push of a button, or get a machine that will pull a great shot with a bit more required effort and skill.
