Koryaiko 100ml borosilicate espresso measuring cup review

A 100ml graduated glass at around ₱152 as of August 19, 2026, from a coffee-accessory brand. This is not a baking tool, and it is worth knowing what it is.

What a graduated shot glass is for

Espresso is defined by three numbers: how much dry coffee went in, how long the shot ran, and how much liquid came out. The last one is yield, and it is the number a shot glass shows you.

A standard double runs somewhere around 36 to 40g of liquid out of an 18g dose. Pull less and you get a ristretto, thicker and sharper. Pull more and you get a longer, thinner shot. Being able to see where the flow has reached, while it is running, is how you learn to stop it in the right place.

At 100ml this holds a double comfortably with room to see it arrive.

Volume is the rough version of that measurement

Here is the honest limitation. Espresso comes out with crema on top, and crema is foam. It settles over the first minute, so the level you read at the end of the shot is not the level you read a minute later.

Weight does not do that. A small scale under the cup gives you a repeatable number, which is why most people who care about yield weigh rather than measure.

So a graduated glass is the visual, in-the-moment version: good for learning where your shots land and for spotting a run that is going long, less good as the number you record.

Borosilicate is the right call here

Espresso leaves the machine at around 90 degrees and lands in a cup that has been sitting at room temperature. Ordinary soda-lime glass expands as it heats, and a fast temperature jump stresses it.

Borosilicate barely expands, which is why it is the material for anything that meets hot liquid suddenly. For a cup whose entire job is catching something very hot, it is not a premium feature, it is the specification.

Where it sits on price

Around ₱152 makes this the cheapest of the three Koryaiko cups on this page and a fraction of the MHW-3BOMBER 100ml stainless cup at around ₱580 for the same capacity.

The stainless cups cannot show you the shot at all, which for this particular job is a real difference rather than a matter of taste.

Who should buy the Koryaiko 100ml

Buy this if you pull espresso at home, you want to see yield while the shot runs, and you would rather not spend on stainless you cannot see through.

Skip it if you already weigh your shots, or if you wanted a measuring cup for cooking.

The other coffee cups, and the kitchen ones

For a heat-insulated handle, see the Koryaiko 120ml cup with wooden handle. For measuring liquids in cooking rather than coffee, the Eurochef 250ml borosilicate jug is the kitchen equivalent.
