Olympia Express Shot Mirror Mini Black – Espresso Mirror for Bottomless Portafilters
The small mirror that is placed under the bottomless portafilter and shows you during extraction what you would otherwise never see: the underside of the filter basket in full action. Channeling, spraying, dripping, the formation of crema layers – all in real-time, right before your eyes.
What makes this mirror special
Diagnostic tool for honest extraction
A bottomless portafilter shows you the puck during extraction – with the Shot Mirror Mini, even from the perfect angle. You immediately recognize channeling (individual streams shooting through), feel if your distribution worked, see the first honey-like drops, followed by the dense build-up of crema. A learning tool you won't want to do without.
Swiss craftsmanship in a compact format
Black casing, compact size that also fits under a shallow cup. Angled mirror surface so you can look at it in a normal posture. From the factory in Schwanden GL.

Frequently asked questions
What exactly do I see in the Shot Mirror?
The underside of your bottomless filter basket during extraction. You can see where the first stream exits, whether the espresso drips evenly from the entire puck surface, whether you have channeling (individual, early streams shooting through), or whether the distribution worked cleanly.
Do I absolutely need a bottomless portafilter for this?
Yes. With a classic spouted portafilter, you only see the spouts – with a bottomless one, you see the filter basket directly. Only then does the Shot Mirror work.
How do I clean the mirror?
Wipe the mirror surface with a soft cloth after each shot, occasionally clean with warm water. No abrasive agents – the mirroring must not be damaged.
Where can I buy the Shot Mirror 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) you can see it live.
Roastery Tip
The Shot Mirror is one of those tools you didn't know you needed – until you use it. Suddenly, you see distribution errors that you never would have noticed before. Profiling is a learning process, not an act of total control – the Shot Mirror helps you to be more honest with yourself. Our opinion, one of many.
