A double-ended bar jigger that handles the two measurements you need for almost every cocktail recipe. The 30ml side covers a standard Australian spirit pour for highballs, sours, and most classic cocktails. The 15ml side handles half pours, syrups, liqueurs, and dashes of accent spirits like vermouth or absinthe. Flip the jigger between sides as you build the drink, and you've covered the volume measurements for the majority of cocktails on a typical bar list.
For bartenders, the value is in the speed. Free-pouring works for some experienced bartenders, but jigger pours are the standard for any bar that cares about consistency, cost control, and matching the spec on every drink. A jigger is also faster than people assume — once your hand learns the motion, jiggering a Negroni takes about three seconds, and you've measured it correctly every time rather than over-pouring by 5ml.
The build is what matters here. Thick stainless steel rather than the thin pressed metal that bends out of shape after a few months of bar use, holds its volume markings accurately, and survives being dropped on a service mat or knocked into the rinse sink. Corrosion-resistant for the citrus, syrup, and spirit-heavy environment of a bar bench.
Useful at home for anyone serious about cocktails. The difference between a great Negroni and a mediocre one is whether the proportions are right, and that's almost impossible to do reliably by eye.
Australian standard sizing — 30ml is the standard spirit pour. (Note: US recipes often spec 1oz/30ml or 1.5oz/45ml, so US-recipe drinks may need a 1.5x pour using both sides combined.)
