The essential mixing glass for classic cocktails

Not every cocktail should be shaken. Spirit-forward cocktails are traditionally stirred with ice to achieve precise chilling and controlled dilution while preserving exceptional clarity. This technique has been used by professional bartenders for decades and remains the standard for many iconic cocktails.

The CARATS Stirring Glass 747 ml by ONIS has been developed specifically for this purpose, making it an essential tool for cocktail bars, hotel bars, restaurants and passionate home bartenders.

Why stir instead of shake?

The choice between stirring and shaking is not simply a matter of preference.

Cocktails containing citrus juice, dairy, egg white or fruit purées benefit from vigorous shaking, which creates aeration and a lighter texture.

Spirit-only cocktails, however, are stirred to chill the drink while maintaining perfect clarity and a silky texture without introducing unnecessary air bubbles.

This is why classics such as the Martini, Manhattan and Negroni are traditionally prepared in a stirring glass.

Why 747 ml (25 oz)?

The 747 ml capacity corresponds to the professional American standard of 25 oz, commonly used behind cocktail bars around the world.

The generous volume provides enough room for plenty of ice while comfortably preparing one or multiple cocktails without splashing.

The taller liquid column also allows the bar spoon to create a smooth, consistent vortex, resulting in efficient chilling and more controlled dilution.

The CARATS pattern offers more than visual appeal

The cut-glass inspired design gives the mixing glass its distinctive appearance while also improving grip during service. The textured surface catches the light beautifully, making both the glass and the finished cocktail look exceptional behind the bar and in photographs.

A thick, weighted base further improves stability while stirring.

Designed for professional bar tools

The opening is perfectly suited for use with both Julep Strainers and Hawthorne Strainers, allowing cocktails to be poured cleanly into the serving glass.

Combined with a professional bar spoon, it supports the same stirring techniques used in craft cocktail bars and international bartending competitions.
