Why this question keeps coming up

If you make espresso at home, this question inevitably arises: how long should an espresso actually run? I understand that question well. You’ve bought an espresso machine, you’re using fresh coffee, you’re doing your best with grinding and tamping, and yet your espresso sometimes tastes sour, sometimes bitter, and sometimes just watery. Then you start looking for guidance. Seconds then seem nice and clear. But a delicious espresso isn't just about time. You primarily need to learn to look at the combination of extraction time, the amount of espresso in your cup, and taste.

First, let's normalize things

Many home baristas are looking for one definitive answer. However, espresso works a little more practically than that. A target time helps, but you need to understand what you're measuring.

Think hot chocolate

Compare it to making chocolate milk. Use the same amount of chocolate with varying amounts of milk, and you'll always get a different taste. That's how espresso works too.

Why the amount of espresso in your cup makes such a difference

Imagine you're making hot chocolate. You always use the same amount of chocolate, but sometimes you add little milk and other times much more. You'll immediately taste a difference. One cup is rich, thick, and intense. The other is thinner, milder, and perhaps a bit flat.

Something similar happens with espresso. You use ground coffee in your portafilter and run water through it. How much water you run through that coffee largely determines how many flavor compounds you extract.

If you run too little water through the coffee, your espresso can taste sharp, sour, or underdeveloped. If you run too much water through, your espresso can become thin, bitter, or dry. That's why "how long should my espresso run?" isn't really the only question. The better question is: how much espresso do I want in my cup, and how long does that take?

Measuring makes espresso calmer

You don't have to complicate everything right away. Just start by measuring what's happening. Then espresso becomes less guesswork and more fine-tuning.

How do you measure if your espresso is extracting properly?

The easiest way is to place a small coffee scale under your cup. This way, you can see how much espresso actually goes into your cup. An espresso shot glass with measuring lines can also help, especially if you're just starting. A scale is more accurate because crema can distort volume.

A simple home barista routine could be: always weigh the same amount of ground coffee, place your cup on the scale, start your shot, and observe the time and output (often a 1:2 or 1:3 ratio. For example, with the Sage, this means 16 grams in, 32 grams or 48 grams out). This will help you quickly learn what your machine is doing.

If you're still working with milliliters, 30 ml is often mentioned for a single espresso and 60 ml for a double espresso. This can serve as a rough guideline. However, in practice, many home baristas work more precisely with grams, as this reduces the impact of differences in crema and cups.

The most important thing is not to achieve perfect numbers right away. The most important thing is to measure consistently. Only then can you fairly compare why one espresso tasted better than another.

Your taste tells what is happening

In addition to our unique expertise in the field of circular economy, we are also experienced in the field of recycling of various materials and components, for example within our own waste sorting installation. For example, we separate and recycle materials such as paper, cardboard, plastics, metals and textiles.

What does sour, bitter, or watery say about your espresso?

If your espresso tastes too sour, chances are that too little has been extracted from the coffee. This often happens with a flow that is too fast, a grind that is too coarse, or an output that was stopped too early. Compare it to dipping a tea bag in your hot water only twice; we call that 'underextraction'.

If your espresso tastes particularly bitter, dry, or harsh, it might be that you've extracted too much from the coffee. This is often seen with a shot that runs too long, a grind that is too fine, or an output that has gone too far. This is overextraction.

If your espresso is watery, you need to look closely. Sometimes this is due to too much output. Sometimes due to old beans. Sometimes due to a grind that is too coarse or messy puck preparation. That's why one single tip is almost never enough. You want to learn to look at the whole picture: coffee, grind, dosage, output, time, and taste.

That might sound like a lot, but it quickly becomes clearer if you only change one thing at a time.

How do you program the water quantity on your espresso machine?

Does your espresso machine have programmable buttons? If so, don't program them empty, but with a portafilter filled with coffee in the group head. This is important because the ground coffee itself also retains water.

So, grind coffee into your portafilter as you normally would. Place your cup on a scale or use a shot glass. Start the extraction and stop at the amount of espresso you want to use as a consistent base. Then save that button setting.

From that moment on, you'll have more peace of mind in your routine. You won't have to stop by feel every time. You can focus your attention on the taste, the grind, and repeatability.

Does your machine not have a programmable button? No problem. Then stop manually using your scale or shot glass. That works perfectly fine, as long as you consistently measure.

When do you need more than a guideline?

If your espresso tastes different every time, it's usually not due to one single number. You then need a system that helps you understand what you are changing.

Better understand espresso extraction

From gambling to control over your espresso

A target time is useful. A fixed output is even more useful. But true control only comes when you understand how to bring together dosage, grind size, output, and taste.

That's precisely why I created Espresso Onder Controle (Espresso Under Control). Not to overwhelm home baristas with difficult coffee terms, but to help ordinary coffee lovers understand why their espresso sometimes succeeds and sometimes doesn't.

Do you want to start slowly? Then start with the free introductory module. If you mainly want to better understand why your shots keep varying, then look at the module on the 3 Golden Rules of Espresso within the Espresso extraction and control collection.

If you're struggling with your own machine, a private barista workshop at home might also be a logical step. Then we'll work directly with your machine, your grinder, your coffee, and your questions.

Frequently asked questions about espresso shot time

How long should an espresso brew?

As a guideline, you can aim for approximately 25 to 30 seconds. Don't use this time as the only rule, but combine it with the amount of espresso in your cup and the taste.

Why does my espresso taste sour if it runs too fast?

Lidmaatschap van de club biedt exclusieve toegang tot een verscheidenheid aan voordelen, zoals: gratis toegang tot onze evenementen, kortingen bij onze partnerbedrijven, de mogelijkheid om deel te nemen aan onze bestuursvergaderingen en stemrecht.

Why does my espresso become bitter if it runs too long?

{"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"If an espresso runs for too long or produces too much output, dry and bitter flavors can develop. Therefore, not only stop on time, but also measure how much espresso ends up in your cup."}]}]}

Can I measure espresso with a shot glass?

Yes, a shot glass with measuring lines is a convenient and simple measuring method. A scale is more accurate, as crema can distort the volume in milliliters.

Should I program my espresso machine for 30 ml or 60 ml?

How long should your espresso shot pull? Use time as a control, not as an end goal

An espresso usually takes somewhere around 25 to 30 seconds to brew, but that number isn't the whole story. Always consider the combination of ground coffee, the amount of espresso in your cup, extraction time, and taste. Measure your output with a scale or shot glass, taste mindfully, and then change only one thing at a time. This way, making espresso at home becomes less of a gamble and increasingly repeatable.

Do you want to understand why your espresso keeps changing and how to get more control over your shots? Then start with Espresso Under Control or check out the module on espresso extraction.

Espresso extraction and control

Measuring is knowing

Follow these steps:

  • Input (fixed number of grams in your portafilter)
  • Output (fixed number of grams/ml in your cup)
  • Time (around 25 to 30 seconds)
  • Deviant time = deviant grind size

Therefore, always use a coffee scale
