How To Brew Espresso – How to Make the Perfect Espresso

How To Make the Perfect Espresso

When you start to learn how to brew espresso, you get frustrated, and some even give up and they return to the mediocre shots at the famous coffee shop chain. This is understandable, because making the perfect espresso is a complex, elaborated, sometimes intuitive combination of coffee quality, extraction pressure and time, water temperature, coffee grind, and roast, and more... If only one of these parameters is off, your espresso shot will be an average one.

Learn how to brew espresso at home, using an automatic or a manual espresso maker. Tips on pulling the perfect espresso shot and a troubleshooting guide.

As in all areas where talking about savor, aroma, and taste, preparing a good coffee needs strict rules. If you skimp on the beans quality, it will dramatically affect your espresso, a poor grinder will also have a bad effect on the end result, and let's not forget the espresso machine which can make or break your shot. 

But also, Espresso requires preparation and tasting ritual, and some subjectivity. That means that the perfect espresso shot is subject to personal taste and mood. 

Having said that, there are a few factors that are the common ground no matter what is your personal taste. Let's see what are these factors and how can we control them for a perfect shot.

This is an advanced espresso brewing guide, and it assumes you have some knowledge on the subject. You can read it anyway because it provides you with facts that are useful regardless of your knowledge level. If you would rather take it gradually and start from the beginning, I recommend you to read our low budget espresso making page. It is a a great starting point in your barista training journey.

The Perfect Shot

The perfect shot is a subjective term. Many people like ristretto, other prefer a lungo, and other like the normale. The Northern American coffee community has attached an objective description to espresso perfection. The description doesn't take into account personal taste, it's just an ideal extraction of the essence of coffee. This ideal shot is very hard to prepare, most people get it right once out of 5-7 shots. This perfect espresso is referred to as the God Shot, and it's basically a double ristretto. For a detailed description, you can read this article by Mark Prince on

What Is the Perfect Espresso?

You heard someone saying: "This espresso is perfect", but you don't really have a comparison term, and maybe you didn't even like it. Then the question is: "how do you know you have been served a good one?". Here are a few hints that will give you at least an idea of what it means "a good espresso".

  • It should have a consistent layer of the specific brown foam, called crema. Much of the specific taste of espresso resides in its crema, and it accompanies the dark extracted liquid through the end, leaving a unique combination.
  • The taste is in a small measure dependent on the beans' provenience, but more than that, it depends on the roasting art. Bitter is often associated with espresso, but that's not what properly describes it. In fact, a Starbucks shot is bitter, but it is that way because the coffee is over-roast.
  • Furthermore, a long shot tastes different than a regular one, and a ristretto is different as well. And they are not different because of the concentration, they are structurally different.
  • The aroma of an espresso shot is so unique, it resembles somewhat the drip, or the Turkish coffee, or any type of coffee brew, but it is distinct, and you can easily tell espresso from other brew types only by its aroma.

The Perfect Espresso Recipe

"The perfect espresso" is a combination of the coffee beans' quality, the espresso machine's quality, and the barista's skills.
This is what makes up a great espresso shot:

  • An espresso shot contains around 1 oz of brewed liquid and is made from 6 to 8 grams of ground coffee.
  • A double shot, or a doppio, is prepared with 12-14 grams of grounds.
  • The brewed coffee is a mixture of acids, proteins, sugars, aromatic oils, and other substances, in perfect concentration and proportion to enhance the aroma and taste to maximum.
  • The extraction is made by passing hot water - 190 to 202 °F (the espresso brewing temperature in Celsius is 88-94 °C) with a pressure of 9 atmospheres, through the ground coffee.
  • Coffee is placed in the port-filter and pressed with a special tool, (espresso tamper), with about 30 pounds force for that perfect stream of water to pass through the entire dose. If the coffee is too finely ground, the tamping should be lighter.
  • Espresso is just great as it is, with no additions to it, besides maybe a little sugar, or a biscotti. But many people love it as a base for other coffee beverages, such as latte, or cappuccino, or a macchiato.

The Perfect Espresso – Recipe and Preparation Tips

Espresso Recipe Step by Step - The Basics

Espresso brewing is complex, but the simplest espresso recipe is this. For more details around each step, read this page thoroughly.

  • Fill up your water reservoir with spring water.
  • Turn on the espresso machine so it has time to warm up.
  • Weigh your coffee beans on a kitchen scale. You need 14 grams of coffee grounds for a double shot.
  • Grind your espresso beans finely. The ground coffee should be about the size of table salt.
  • Fill your portafilter with the coffee grounds, and make sure you distribute it evenly to avoid channeling.
  • Lightly tap the sides of the portafilter to achieve perfect distribution, or use a distribution tool.
  • Tamp it with about 30 pounds of pressure, I explain more in this tamping tutorial.
  • Insert the portafilter into the brew head of the espresso machine, and press the brew button.
  • If the variables above are correct, you will get a doppio in about 25 seconds, give or take 5 seconds.

Espresso is above all a race against time. Prepare quickly, in just 30 seconds in which hot water passes through the ground coffee beans, at a certain pressure. Ideally, the barista serves the espresso fast and you drink it fast. Ten seconds after pulling the shot, the espresso taste begins to change and the change increases exponentially in time. The fact that the preparation is extremely fast, makes it even easier to miss the perfection. Here are some tips for preparing your best ever espresso:

  • Buy coffee as fresh as possible.
  • Always freshly grind coffee, always.
  • If you don’t buy an “espresso blend”, choose a “Full City Roast” or a “Vienna Roast”
  • Pull the shot at the right temperature. Espresso is brewed at 195 °F to 205 °F, (90 °C – 96 °C). 
  • A regular, single shot is made with around 7-8 grams of ground coffee. You can play a bit with this but start with the standard to get a decent shot, and then experiment your way to greatness.
  • Tamp with around 20 lb to 30 lb pressure. As a beginner, you can tamp on a scale, in time you’ll get the feeling of it. Check the video below to see how to setup your practicing bench. Or if you want precision every time, look at the Espro Calibrated Tamper.
  • The grind should be espresso grind size, and it dictates the tamping force. The finer the grind the lighter the tamping. But this is only if you want to play around. Most baristas will keep the tamping at 30 lb pressure and adjust the grind until they find the sweet spot.
  • Buy  a specialized espresso blend, if you are a beginner, it's safer.

How To Choose the Espresso Beans

Buy coffee as fresh as possible. This is the most important for espresso. Crema is made of CO2, coffee oils, and water. Coffee oils, water and CO2 are emulsified during the extraction, so that the oils and the CO2 form the thin crema layer at the top of the shot. When coffee is old, it loses the two main ingredients in crema - oils and gasses. The older the coffee beans, the less oil and gasses are in the coffee. This is why you should never buy ground coffee, and freshly grind your beans just before pulling the shot. Buy coffee properly stored, or freshly roasted.

Can Espresso Be Made from Any Coffee Beans?

In theory, you can use any coffee beans to make espresso. Espresso is not a coffee bean, or a roast, it is a coffee brewing method. In reality, there is more to it than that. For instance, a darker roast is easier to extract, because the bean's cell structure is softened up with the prolonged roast. A lighter roast will provide better coffee, and the espresso will retain a lot more of the beans' origin, but it is harder to pull, and requires more precision.

Another aspect to consider is the beans' origin.  For instance, many Brazilian beans are great for espresso because they produce a lot of crema. Too much acidity in an espresso is generally perceived as a flaw, although some, (including me), might enjoy them.

When choosing your coffee, you can’t go wrong with Brazilians. If you buy espresso marketed beans, you will be sure you bought good coffee. You can’t go wrong with Illy, but is more expensive. Make sure your espresso blend is from a reputable roaster. Sometimes roasters add too much Robusta in their blend, in order to improve crema. Robusta beans tend to have burnt rubber taste.

If you don’t buy an “espresso blend”, choose a “Full City Roast” or a “Vienna Roast” more about coffee roast.

Espresso Brewing Temperature

Espresso is brewed at 195 °F to 205 °F, (90 °C – 96 °C). Some espresso machines need a warmup before pulling the shot. If your machine doesn’t have that in its program, just pull a blank shot.

What Not To Do When Brewing an Espresso, or Troubleshooting an Espresso

Why My Espresso Doesn't Have Crema

There are other countless ways to fail an espresso. In the first five seconds pre-infusion occurs, the contact between water and the ground coffee, and then in the next 25 seconds follows the actual infusion - the espresso pull.

The 25 seconds of infusion is the time when the flavors and aromas are poured into the cup. A too short pulling time results in a very short espresso with low volume and an acid taste. If the pull is too long, the coffee will be bitter and will mask all of the coffee flavors, and the shot will contain more caffeine. At the end of the pull, the foam turns brown in color, and this foam contains the highest concentration of caffeine. This foam, (la crema), must be dense and thick. Air bubbles or white spots are signs of a poor preparation.

In your quest of preparing a "barista grade" espresso, you need to know the potential problems, that could render your shot bland, or bad:

  1. Coffee is oxidized, (stale) - it had contact with the air more than 4 hours before use;
  2. The coffee tamping is too mild or too hard, or uneven;
  3. Extraction time is too short or too long;
  4. Poor maintenance of the device (you have to clean and descale on a regular basis)
  5. Coffee grind is either too fine or too coarse
  6. Poor quality coffee
  7. Bad tasting water
  8. Cold cups, or cold equipment, (brew head)

There are also problems that you can't control, related to the equipment. You can't change these after you bought a bad espresso machine, but you can choose carefully your next one.

  1. Inadequate pressure, too low or too high, (best machines have a PID)
  2. Water temperature is not consistent

Your Perfect Espresso Shot is a Bit Personal

Normale vs Lungo vs. Ristretto vs. Americano - A Matter of Taste

The perfect espresso is many times a matter of personal taste. Many times, what a barista considers a perfect espresso, is not working for you. I will give you the example of Starbucks espresso; for any coffee connoisseur, their espresso is too bitter because of the excessive bean roast. They still have a constant stream of people who just love their espresso. So, don't let anybody tell you what is the best espresso for you. Experiment with various beans, various extraction times until you get your espresso right for you.

Personalize It

A few variations of the taste and strength can be obtained through the control of the extraction time. The standard espresso shot is called "normale", and it is about 1 fl oz. A slightly longer extraction time will produce a "lungo", which is less concentrated but will contain more caffeine.

If you prolong the extraction time even more, you will obtain the "caffè crema", which is a longer espresso, (longer than lungo), and has the taste of the espresso, but is milder, and it has a bit more caffeine.

"Caffè americano" is similar to a long shot, but is obtained by pulling a long shot, and adding a shot of hot water. The americano It has the strength of a "caffè crema" but it is different because it maintains the espresso flavor profile, but diluted.

Using a short extraction time, you will obtain the "ristretto", a short espresso. Ristretto contains less caffeine but more flavors and aromatic oils. If your espresso machine has the capability, you could prepare the ristretto by shortening the extraction time but pushing the same amount of water through the coffee grinds. The result will be similar, but you will have more coffee in your cup. Ristretto is less bitter than normal, (regular espresso), and is more flavorful.

How to Serve and Drink an Espresso

Tips to Enhance your Espresso Experience

Serving and drinking espresso is part of a ritual that makes up the whole espresso experience. You need to focus on every detail of the process to enjoy the flavors to the maximum. Here are a few hints.

Porcelain espresso cups maintain optimal coffee temperature for a longer period and maintain the foam and the flavor. There are also glass cups with a double wall that are even better than the porcelain ones, and they look fancier. For optimum results, the cups need to be warmed up before pulling the shot. Oh, by the way, you also need to warm up the portafilter before using it.

Drink Mineral Water with Your Espresso

Drink a few sips of water before your espresso; this will help your taste buds to wipe any previous taste memories. You can also drink water in between your espresso sips. Coffee dehydrates, and you need to drink water.

Espresso is a strong coffee and while is very tasty and bold, for some it is hard on the stomach. A little water between sips won't dilute the taste, but will dilute its strength in the stomach. Drinking water cleanses the palate, so you can drink before taking the first sip, and you can drink it in between sips. 

Mineral water, (sparkling water), is the best because carbonated water neutralizes better lingering flavors in your mouth.

I typically end this routine wit a sip of espresso, because I want the exquisite taste to linger a little longer. Sometime though, I choose to end wit water, so I can wash off the taste of a poorly prepared shot.  

Cookies and Espresso

Mix a bit in your espresso before the first sip, even if you don't add sugar, this will ensure that the first drink is not a bitter one. Some add sugar to their espresso, others eat a biscotti or any other cookies with their espresso, others will just drink it as it is, plain. The cookie's sweetness will contrast with the espresso's bitterness in a good way, accentuating it. 

Is there Such a Thing as a Dead Espresso?

If you heard the term dead espresso and you want to know if it's a real thing, here is the answer: YES and NO. You might be thinking now: "Very useful Dorian, thanks for sharing this..." OK, let's delve a little deeper into it, and I'll explain. 

The term dead espresso as it was coined by certain corporate barista circles, means a shot that is older than 10 seconds. When I pull my espresso shot, it needs a few seconds to cool of. Coffee should not be consumed piping hot because you can't really taste it anymore. So this means that my shot is dead before it even reaches the drinking temperature. You see why this is silly?

On the other hand, a shot that has been sitting for 30 seconds, loses all of its crema. (Rather crema is incorporated into your coffee.) So from an aesthetics perspective, the shot will be dead. However, when I pull myself a triple shot, I drink that over a longer period of time. My espresso will eventually get cold, and I enjoy it. Is it dead? Not to me. 

How Does a Good Espresso Taste

A properly prepared espresso is vaguely fruity, floral, slightly sweet, reminiscent of chocolate and caramel tones. Bitterness is a quality sign only if it's gently weighted by a little acidity.
