Koryaiko 30ml/60ml double-head stainless measuring cup review

Two cones welded base to base, 30ml at one end and 60ml at the other, at around ₱199 as of August 19, 2026. It is a jigger, and it is the most precise thing on this page for the amounts it covers.

Why a fixed volume beats a graduated one at this size

Every other liquid measure here works by reading a line on the side. That only works well when the vessel is narrow relative to the amount, which is why 50ml in a litre jug is a guess.

A jigger sidesteps the problem entirely. There is no line to read, because the vessel is the measurement. You fill it to the brim and stop, and the answer is the same every time regardless of your eye level, the light, or how steady your hand is.

For 30 and 60ml specifically, that makes it more repeatable than any jug on this page.

Where the two sizes come from

Thirty and sixty millilitres are the standard single and double pour behind a bar, and they are close to one and two US fluid ounces.

They are also two amounts that turn up constantly in cooking. Thirty millilitres is almost exactly two tablespoons, which covers vanilla, vinegar, soy sauce, fish sauce, oil and syrup. Sixty covers the same things doubled, plus a small pour of milk or cream.

So even if you never make a cocktail, the tool is not wasted.

The trade for the precision

Stainless steel is opaque, so you cannot watch a level rise through the side, and the graduation, if any, sits inside the cone where you have to look down into it.

That makes it useless for the job a graduated jug does: measuring some amount you choose rather than the two it offers. And it makes it wrong for espresso, where the whole point is seeing the shot arrive.

It is a single-purpose tool that does one thing exactly, and that is the right way to think about it.

Stainless is the right material for it

It will not stain, it will not hold a smell, and it survives being dropped. Something that measures soy sauce, then calamansi juice, then vanilla needs exactly that, and it is the reason bar tools are steel rather than plastic.

Who should buy the double-head cup

Buy this if you make drinks at home, or you want a repeatable way to pour small amounts in cooking without reading a line.

Skip it if you want one tool that measures any amount, where a graduated jug is the answer.

The measuring tools either side of it

For a graduated glass you can watch a shot fill, see the Koryaiko 100ml borosilicate espresso cup. For general cooking amounts, the Eurochef 250ml borosilicate jug covers what a jigger cannot.
