How much pressure do you tamp espresso?

Answered by Andrew Fritz

When it comes to tamping espresso, there is a wide range of opinions on how much pressure to apply. Baristas often recommend 30 pounds of pressure, but some may tamp with as little as 20 pounds. It's important to note that the pressure applied during tamping can have a significant impact on the extraction and flavor of the espresso shot.

Tamping is the process of evenly compressing the grounds in the portafilter before . This step is crucial in creating a level and consistent surface for the to pass through, ensuring proper extraction. The goal is to achieve a compacted puck of coffee that allows the water to flow evenly and extract the desired flavors.

The recommended range of 20-30 pounds of pressure is a general guideline, but ultimately, the ideal pressure may vary depending on the coffee, grinder, and personal preference. Some factors to consider when determining the right pressure include the grind size, coffee dose, and the equipment being used.

If the coffee is ground coarser, a higher amount of pressure may be needed to achieve proper extraction. On the other hand, a finer grind may require less pressure to avoid over-extraction. It's important to experiment and adjust the pressure based on the specific coffee being used.

Personal experience plays a crucial role in determining the right tamping pressure. As a sommelier and brewer, I have encountered various situations where adjusting the tamping pressure had a noticeable impact on the taste of the espresso. For instance, when working with a particularly dark roast, I found that using a slightly lower tamping pressure of around 25 pounds resulted in a more balanced and flavorful shot.

It's worth noting that consistency in tamping pressure is also essential. Applying consistent pressure across all the coffee grounds ensures an even extraction. To achieve this, some baristas use a calibrated tamper, which helps provide a consistent level of pressure every time.

The recommended range for tamping espresso is typically 20-30 pounds of pressure, but it can vary depending on the specific coffee, grind size, and personal preference. Experimenting with different pressures and paying attention to the taste and extraction of the espresso can help determine the ideal tamping pressure for a particular situation.
