Olympia Express Gauge 16 Bar for Mina – Pressure Display at the Brew Head
The original Mina gauge – display range up to 16 bar, integrated at the brew head. It shows you in real-time the pressure you generate when pressing down the lever. The Mina is one of the few mobile espresso machines with a built-in pressure display – no electricity, no battery, just honest mechanics. Original part from Schwanden GL.
What makes this gauge special
Display range up to 16 bar – more than any espresso needs
Classic espresso is extracted in the range of 8 to 10 bar, usually around 9 bar. The Mina gauge displays up to 16 bar – the oversized range provides a reserve for maximum lever force and visual safety. You can see whether you are in the espresso sweet spot (8–10 bar) or above.
Learning aid for lever machine beginners
Unlike electric machines with pumps, with the Mina, you have to build up pressure yourself. The gauge is your display – over weeks, you learn what 9 bar feels like in your hand. After a while, you won't need it, but at the beginning, it's worth its weight in gold.
Mechanical, no electricity
Pure mechanical gauge – no battery, no electronics, no app calibration. Works just as well at the beach as at home.

Frequently Asked Questions
How many bar do I need for espresso?
The classic espresso pressure sits in the range of 8 to 10 bar, usually around 9 bar. With the Mina, you build up this pressure with your hand on the lever – the gauge shows you whether you are in the sweet spot (8–10 bar) or above.
Why does the display range go up to 16 bar?
Reserve. With very strong movements of the lever, the pressure can briefly exceed 10 bar – the gauge shows this honestly, instead of getting stuck at the stop.
Where can I buy the gauge or see it live?
Online via coffeecoachingclub.ch. On-site in our showrooms in Bern (Gerberngasse 44, 3011 Bern) and Zurich (Hagenholzstrasse 50b, 8050 Zurich).
Roastery Tip
The Mina gauge is one of the most honest learning tools for lever machines – at the beginning, you look at it every second, after a year you hardly need it anymore because your hand has developed the feel. A new gauge gives you back the learning process if the old one is worn out. Our opinion, one of many.
