Adjustable Espresso Shot Mirror for Bottomless Portafilters

Want to see what’s happening under your bottomless portafilter without crouching beside the machine? This adjustable espresso shot mirror gives you a view of the extraction while you stay focused on your shot.

The 360° swivel lets you adjust the viewing angle to suit your setup. It’s a simple tool for watching how espresso emerges from the basket and spotting uneven flow as you work on your grind, distribution, and tamp.

What you’re getting

• Adjustable viewing angle: A 360° swivel helps you position the mirror beneath your portafilter.
• Wood and glass construction: A natural wood component paired with a glass mirror.
• Listed size: 8 × 5.5 cm.
• Included: One espresso shot mirror. Espresso machine and portafilter are not included.

How to use it

Place the mirror where you can see the underside of your bottomless portafilter, adjust the angle, and pull your shot. Check that it sits securely and leaves enough room for your cup before brewing.

Do you need a bottomless portafilter?

For a view of espresso emerging directly from the basket, yes. A bottomless portafilter exposes the basket’s underside; a spouted portafilter hides that view.

Does it measure espresso flow?

No. This is a viewing tool, not a scale, timer, or flow meter. It helps you observe your extraction, but it won’t fix an uneven shot on its own.

If you’re learning to dial in espresso, seeing the extraction can make it easier to understand what to adjust next. Less guessing, a better view.
