Q: What is passive pre-infusion and why does it matter?
A: During the initial phase of extraction known as pre-infusion (on machines that feature it), the coffee bed will become fully saturated before full brew pressure is achieved. This settles the coffee and ensures that all particles are evenly reached by the water, creating a more well-rounded flavor.

Essentially, passive pre-infusion refers to the fact that you do not need to manually control this stage of extraction.

And since you can program the passive pre-infusion in the S1 Vivaldi II for different lengths of time, you have more control than in a passive pre-infusion system like the one that comes with an E-61 group. Meanwhile, you retain the simplicity and ease of the passive system.

Q: What does a manometer do on the Vivaldi ii?
A: A manometer shows you a pressure measurement. In the case of the S1 Vivaldi II, the dual manometer displays the boiler pressure as well as the pressure built while the pump is active during brewing.

By reading the boiler pressure gauge, you’ll have a clearer understanding of when you can use the machine, as in when you can brew espresso and steam milk. You’re looking for the right pressure reading.

The group pressure gauge guides you toward the right brew ratio. So when you’re pulling a shot and the pressure is not building correctly, you know that it’s time to adjust an element of your brew ratio, such as how much coffee you’re using.

Q: Why is the offset differential important?
A: Typically, there is a difference between the boiler temperature readings an espresso machine is producing and the actual temperature of the water coming out of the group. This is because there are natural temperature differences between the water sitting in the boiler and the water that has traveled to the group.

Differences shouldn’t be vast, but even slight variations can change your espresso results. As such, if you’re serious about espresso, you may want to get out a temperature reader to test the group water on any espresso machine.

The S1 Vivaldi II solves the problem by letting you adjust the LED temperature setting so that it matches the group temperature—not the boiler temperature. This way, you’ll know exactly what temperature you’re extracting espresso at.
