MUVNA Star Rain Glass Espresso Measuring Cup TC0421, V-Spout
Guaranteed Safe Checkout
A glass espresso measuring cup that fits under the spoutLow enough for the drip tray, marked for the shot, poured without a drip.
This MUVNA espresso measuring cup is a squat glass that takes up to 100 ml (3.38 oz) and carries lines at 30, 45 and 60 ml (1.01, 1.52 and 2.03 oz). Heat-resistant glass with an iridescent rainbow finish forms the body, and a V-shaped spout empties it without drips. Standing 4.2 cm (1.65 in) tall, it leaves room for a scale beneath a bottomless or dual-spout portafilter on a home espresso bar.
- Holds 100 ml (3.38 oz)
- Three graduated shot lines
- V-spout pours without drips
- Heat-resistant iridescent glass

Three details that matter at the machine
Low and wide
At 4.2 cm (1.65 in) tall and 6.4 cm (2.52 in) across, it slides under the group head and sits flat on a coffee scale.
Lines you can read mid-shot
The marks show the volume as it fills, with headroom to the full 100 ml (3.38 oz) for longer pours.
A spout that stops the dribble
The V-shaped lip sends espresso, syrup or other liquids into the next cup in one clean stream.
The iridescent rainbow finish is what catches the eye on the drip tray.
Check the gap under your group head
Measure from the drip tray, or the top of your scale, to the portafilter spouts. You need 4.2 cm (1.65 in) plus a little room for the stream. The listed size was taken by hand, so allow a small margin.

The details

Who this little glass suits
A good pick if you
- Make espresso in your own kitchen and like seeing every shot rise against marked lines
- Weigh every pull on a scale such as the MUVNA Palm mini scale
- Like barista tools that look good on the counter
Look elsewhere if you
- Want a cup for a large coffee, since it tops out at 100 ml (3.38 oz)
- Prefer plain clear glass over an iridescent finish
Answered plainly
What is an espresso measuring cup used for?
It catches your shot under the portafilter so you can see how much you pulled. This one is marked at 30, 45 and 60 ml (1.01, 1.52 and 2.03 oz) and pours into your drink through its V-shaped spout.
Will it fit under my portafilter with a scale on the tray?
It will if you have more than 4.2 cm (1.65 in) between the scale top and the spouts. It is low by design for dual-spout and bottomless portafilters.
Can it take hot espresso straight from the machine?
Yes. The body is heat-resistant glass, made for fresh shots coming off the group head.
Is the 2-piece option two identical cups?
Yes. You get two of the same iridescent cup, handy for splitting a double shot under both spouts. Pair them with the MUVNA precision dosing cup for the ground coffee side of the bar.
