Unlock Dynamic Pressure Profiling on Your Profitec Go Espresso Machine | BrewRatio Singapore

Summary

In this video, the Buay Show introduces an exciting espresso tip: pressure profiling for the Profitec Go. Pressure profiling allows for greater control over espresso extraction by adjusting pressure during various stages. The video covers the steps to enable pressure profiling, including marking the steam knob position, using a blind filter, and making micro-adjustments during the shot. This method enhances flavor, sweetness, and texture, unlocking the full potential of your espresso. Whether experimenting with flavors or refining techniques, pressure profiling offers a new dimension to your coffee experience.

Takeaways

• 😀 Pressure profiling allows you to adjust the pressure during espresso extraction, giving you control over every stage of the process.
• 😀 You can perform a gentle pre-infusion to saturate the coffee evenly, followed by a lower pressure extraction towards the end of the shot.
• 😀 Pressure profiling offers greater control compared to a static extraction, allowing for improved flavor and texture.
• 😀 A well-executed pressure profile can enhance sweetness, distinct flavors, and refine the texture of your espresso.
• 😀 To enable pressure profiling, you need a small sticker to mark the starting position of the steam knob.
• 😀 Start by turning the steam knob fully clockwise to ensure it's closed, then mark its starting point with the sticker at the 'CH' of the clock position.
• 😀 Insert the blind filter basket into the portafilter, lock it into the brew group, and press the coffee button to activate the water pump.
• 😀 Watch the pressure gauge and use the sticker to note when the pressure starts to drop—this marks the opening position of your valve.
• 😀 The opening position of your valve is key to consistent results when creating a pressure profile shot.
• 😀 To brew a pressure profile shot, adjust the steam knob during pre-infusion, gradually reduce pressure, and end with higher pressure for the final stage of the shot.

Q & A

What is pressure profiling in espresso brewing?

Pressure profiling allows you to adjust the pressure during espresso extraction, giving you control over every stage of the process. It enables techniques like gentle pre-infusion and varying pressure throughout the shot for more consistent results and better flavor development.

How does pressure profiling enhance the espresso shot?

Pressure profiling enhances the espresso shot by providing greater control over the extraction process. It can help bring out distinct flavors, improve sweetness, and refine the texture of the espresso, unlocking new dimensions in the final cup.

What equipment is needed to start pressure profiling on the Profitec Go?

To enable pressure profiling on the Profitec Go, you will need an indicator sticker to mark the starting position of the steam knob, a blind filter basket, and a portafilter. Additionally, ensure that the steam knob is adjustable and the machine is set up correctly.

How do you mark the starting position for pressure profiling?

To mark the starting position, turn the steam knob fully clockwise to ensure it is closed, then place an indicator sticker at the 'CH' position on the knob. This sticker helps you track the starting point of the steam knob for reference during profiling.

Why is the blind filter basket used in pressure profiling?

The blind filter basket is used to prevent water from flowing into the coffee grounds, enabling pressure to build up in the system. This step is crucial to test the pressure and identify the correct opening position for the steam valve.

What role does the steam knob play in pressure profiling?

The steam knob is used to adjust the pressure during the extraction process. By rotating the steam knob clockwise or counterclockwise, you can control the flow of water and maintain specific pressure levels throughout the shot, such as during pre-infusion or adjusting pressure mid-shot.

How do you perform a pre-infusion with pressure profiling?

For pre-infusion, you gradually release pressure to maintain a steady 3-4 bar by making micro-adjustments to the steam knob. This gently saturates the coffee grounds, ensuring an even extraction before increasing pressure to the optimal levels.

What should you do after completing the pre-infusion stage in pressure profiling?

After the pre-infusion stage, rotate the steam knob clockwise to close the valve and increase pressure up to the OPV (over-pressure valve) limits. This allows for a higher pressure extraction during the mid-shot phase.

How do you reduce the pressure during the espresso shot?

To reduce the pressure during the shot, gradually turn the steam knob counterclockwise, bringing the pressure down to around 6 bars. This softer extraction enhances the flavor clarity and balance of the espresso.

What is the benefit of using pressure profiling with the Profitec Go?

Using pressure profiling with the Profitec Go gives you unparalleled control over your espresso shots. It allows for experimentation with different flavor profiles, precise adjustments in pressure, and an overall higher quality of espresso compared to static extraction methods.
