Featuring the Pressensor Built-In Kit for the Kees van der Westen Spiritello

Kees van der Westen Spiritello + Pressensor

Lever espresso machines have always been appreciated for their tactile brewing experience, mechanical feedback, and ability to produce expressive extractions. But today, modern espresso workflows are evolving beyond feel alone. Data, consistency, and repeatability are becoming equally important, especially in professional coffee environments.

This is where pressure profiling and real-time extraction data begin to change the conversation.

At Roasttrip, we’ve been working closely with Pressensor to bring a more integrated pressure-monitoring solution to the Kees van der Westen Espresso Machines Spiritello through the Pressensor Built-In Kit.

What Is Pressure Profiling?

Pressure profiling refers to monitoring and controlling how pressure behaves throughout an espresso extraction.

Traditional pump machines often follow a fixed pressure curve. Lever machines, however, naturally create a declining pressure profile during extraction, one of the reasons many coffee professionals appreciate the texture, sweetness, and body associated with lever espresso.

With pressure profiling data, baristas can better understand:

Pre-infusion behavior
Pressure decline throughout extraction
Flow consistency
Channeling tendencies
Extraction repeatability

Rather than relying purely on instinct, baristas gain a visual understanding of what is happening during the shot.

Lever Espresso, Now Backed by Real-Time Data

The Pressensor Built-In Kit for the Spiritello combines the traditional lever espresso experience with modern extraction analysis.

The kit includes:

Bluetooth-enabled pressure transducer
Dedicated installation kit
Installation manual
Real-time pressure monitoring via the Pressensor App

This allows users to visualize extraction pressure curves directly from the machine while maintaining the clean aesthetic and workflow of the Spiritello.

The result is a setup that still feels mechanical and hands-on, while offering the precision and feedback modern coffee professionals often look for.

Why It Matters for CafEs and Coffee Professionals

Consistency is one of the biggest challenges in espresso preparation, especially in high-volume environments.

By analyzing pressure curves, cafés can:

Train baristas more effectively
Replicate successful extractions
Identify inconsistencies faster
Improve recipe development
Better understand how roast profiles behave under pressure

For lighter coffees, pressure data can help refine acidity and clarity.
For darker roasted coffees, it can help control bitterness while maximizing sweetness and body.

This becomes especially valuable for cafes working with:

Seasonal coffees
Competition coffees
Experimental roast profiles
Lever espresso programs

The Spiritello + Pressensor Combination

The Kees van der Westen Espresso Machines Spiritello already stands apart through its mechanical lever workflow, thermal stability, and visual presence.

The addition of the Pressensor Built-In Kit expands what the machine can do operationally without changing what makes it special.

It remains a true lever machine, simply with added visibility into extraction behavior.
