How To Use A Pump Espresso Machine

Using a pump espresso machine requires a careful approach to ensure that you produce the best possible shot of espresso. Here’s a step-by-step guide on how to use a pump espresso machine:

  • Preheat Your Machine: Start by switching your espresso machine on and letting it heat up. This usually takes about 15 to 25 minutes, depending on the machine. It’s important to allow your machine to properly preheat to ensure that your espresso extracts at the right temperature.
  • Grind Your Coffee: While the machine heats up, you can grind your coffee. For espresso, you want a fine grind but not too powdery. The correct grind size should look like fine beach sand.
  • Measure and Tamp Your Coffee: Use a scale to measure the right amount of coffee. The standard dose for a double espresso is about 18-20 grams, but this can vary depending on your machine and personal preference. Place the ground coffee into your portafilter and then use a tamper to apply even pressure to the coffee grounds. The aim here is to create an even, compact bed of coffee for the water to pass through.
  • Insert the Portafilter: Attach the portafilter to the group head of your espresso machine. Make sure it’s properly locked in place.
  • Brew Your Espresso: Start the shot by turning on the pump. A good espresso extraction should take about 25-30 seconds from when you start the pump, but this can vary depending on your machine and the coffee you’re using.
  • Steam Your Milk (if making a milk-based drink): If you’re making a latte, cappuccino or other milk-based drink, you’ll want to steam your milk while the shot is extracting. Place the steam wand into your pitcher of milk, turn on the steam, and froth the milk until it reaches the desired temperature and texture.
  • Clean Up: After you’ve finished brewing your coffee, remove the portafilter and knock out the used coffee grounds. Rinse the portafilter and group head, and wipe them dry.
  • Enjoy: Your espresso or espresso-based drink is now ready to enjoy!

Remember, practice makes perfect, and you might need to adjust your grind size, coffee dose, or extraction time to get your espresso tasting exactly how you like it. Keep experimenting and enjoy the process!


Using a pump espresso machine can be a delicate process as it involves a balance of several variables to achieve the perfect shot of espresso. Here are some tips to help you get the best out of your machine:

  • Preheat Your Machine: Allow the machine to heat up properly before brewing. A well-heated machine ensures that your espresso extracts at the correct temperature, which is vital for good flavor extraction.
  • Use Freshly Roasted Coffee: Coffee beans are at their best within two weeks of being roasted. Using freshly roasted beans can dramatically improve the taste of your espresso.
  • Grind Immediately Before Brewing: Coffee starts to lose flavor as soon as it’s ground. For the best taste, grind your coffee beans just before you’re ready to brew.
  • Find the Right Grind Size: The grind size is crucial in espresso brewing. Too coarse, and your espresso will be weak and under-extracted. Too fine, and it could become over-extracted and bitter. Aim for a grind size that looks like fine beach sand.
  • Dose Correctly: Use a scale to measure your coffee dose. Typically, for a double shot of espresso, you’ll need between 18-20 grams of coffee. However, this can vary based on personal preference and the specific coffee you’re using.
  • Even Tamping: When tamping, ensure the coffee is distributed evenly in the portafilter and that you apply pressure straight down. Uneven tamping can lead to uneven extraction, resulting in poor-tasting espresso.
  • Monitor Your Extraction Time: The ideal extraction time for a shot of espresso is usually between 25-30 seconds, but this can vary depending on your machine and coffee. If your shot is running too fast or too slow, adjust your grind size accordingly.
  • Clean Your Machine Regularly: Coffee leaves behind oils and residues that can build up over time and affect the taste of your espresso. Regularly clean your machine, including the portafilter and group head, to ensure it’s always ready for the next brew.
  • Quality Water: The water you use in your espresso machine can have a significant impact on the taste of your coffee. Use filtered water if your tap water is hard or has a strong taste or odor.
  • Experiment: Espresso brewing is as much an art as it is a science. Don’t be afraid to experiment with different coffees, grind sizes, and brewing times until you find what works best for you. Enjoy the process and learn from each shot you pull!

Frequently Asked Questions (FAQ’s)

Q: Why do I need to preheat my espresso machine?

A: Preheating ensures that the machine reaches the ideal brewing temperature, which is crucial for extracting the best flavor from your coffee. If the machine isn’t properly heated, your espresso may taste under-extracted and weak.

Q: How do I know the right amount of coffee to use?

A: The right amount of coffee can depend on several factors, including the size of your portafilter and your personal taste preferences. However, a general rule of thumb for a double shot of espresso is about 18-20 grams of coffee.

Q: Why is the grind size important?

A: The grind size affects how quickly water can flow through the coffee in your portafilter. If your grind is too coarse, the water will flow through too quickly, leading to under-extraction. If your grind is too fine, the water will flow through too slowly, leading to over-extraction.

Q: What should I do if my espresso is extracting too quickly or too slowly?

A: If your espresso is extracting too quickly, it may taste weak or sour. In this case, try making your grind size finer. If your espresso is extracting too slowly, it may taste bitter. Try making your grind size coarser in this case.

Q: How often should I clean my espresso machine?

A: It’s a good idea to do a quick clean of your machine after each use. This involves removing the used coffee grounds, rinsing the portafilter and group head, and wiping them dry. In addition, you should do a more thorough clean of your machine every 1-2 weeks, which can involve backflushing and descaling.

Q: Can I use tap water in my espresso machine?

A: The quality of water can have a significant impact on the taste of your espresso. If your tap water is hard or has a strong taste or odor, it may be better to use filtered or bottled water. Also, using hard water can lead to scale buildup in your machine, which can cause damage over time.

Q: What is the function of the pump in an espresso machine?

A: The pump in an espresso machine is used to force hot water through the compacted bed of coffee at a high pressure. This high pressure, usually around 9 bars, is necessary to extract the full flavor from the coffee grounds and create the characteristic crema on top of the espresso.

Q: What is the ideal extraction time for a shot of espresso?

A: The ideal extraction time for a shot of espresso is usually between 25-30 seconds from when the pump is started. However, this can vary depending on a number of factors, including the grind size, the dose of coffee, and the specific coffee beans being used.

Q: How can I tell if my espresso has been correctly extracted?

A: The key indicators of correctly extracted espresso include its volume, extraction time, taste, and appearance. For a double espresso, you’d typically aim for around 60ml (2 ounces) of liquid extracted in 25-30 seconds. The espresso should have a balanced taste, not too bitter or sour, and should feature a thick, golden crema on top.

Q: Why is my espresso bitter?

A: Bitterness in espresso is usually a sign of over-extraction, meaning the water has spent too much time in contact with the coffee grounds, extracting too many compounds. This can happen if your grind size is too fine or your extraction time is too long. You can try adjusting these parameters to solve the problem.

Q: What role does water temperature play in espresso extraction?

A: Water temperature is crucial in espresso extraction. The ideal water temperature is around 93-96°C (200-205°F). If the water is too hot, it can over-extract the coffee, leading to a bitter taste. If it’s too cool, it can under-extract the coffee, resulting in a sour taste.

Q: How do I ensure consistent tamping pressure?

A: Consistency is key when it comes to tamping. Many professionals aim for about 30 pounds of pressure, but the exact amount isn’t as important as being consistent every time you tamp. Some people find it helpful to use a bathroom scale to practice their tamping pressure.

Q: How should I maintain my pump to ensure it operates effectively?

A: Regular maintenance is crucial for the longevity of your pump. This includes regular backflushing (if your machine supports it), descaling to remove mineral deposits, and occasionally checking the pump pressure. If your machine is used heavily, you might also need to replace the pump every few years.

Q: Can I use any type of coffee in my espresso machine?

A: While you can technically use any type of coffee in an espresso machine, certain types of coffee will produce better results. Espresso is typically made with a blend of beans that’s been roasted to a medium or dark level. Single-origin beans can also be used, but they may produce a more acidic shot.

Q: What is the best way to steam milk for a latte or cappuccino?

A: The best way to steam milk involves two steps: aerating and swirling. Aerate the milk by keeping the steam wand near the surface of the milk until it reaches the right temperature (around 60°C or 140°F), then submerge it deeper to create a whirlpool effect which will break up any large bubbles and create a smooth, velvety texture.

Q: What should I do if the water flow is too slow or stops entirely during extraction?

A: If the water flow is too slow or stops entirely, it may be due to a number of factors including too fine a grind, too much coffee in the portafilter, or a problem with the machine itself such as a blockage or pump issue. Start by adjusting your grind size or dose, and if the problem persists, consult the machine’s manual or contact the manufacturer.
