Subminimal UpShot Espresso Shot Mirror – the view beneath the portafilter
The first drop appears, dark and dense, and in the slim mirror at the cup's edge you see exactly how the espresso flows from the bottomless portafilter – without bending down or craning your neck.
The UpShot sits right against the edge of your cup and moves so close to the brew group that you keep an eye on what is happening in the bottomless portafilter. This lets you spot channelling and whether your grind size is right.
Rimless glass, magnetically mounted
The glass is ultra-thin, tempered and rimless – at just 0.6 mm thick, the mirror looks delicate and gives an unobstructed view of the extraction. A self-adhesive magnetic mount attaches it to the machine or the wall, so it is always within reach. Thanks to flexible positioning, it suits different cup sizes.
