The SingleDoseBrew Grinds Distribution Tool (GDT) is designed to facilitate the distribution of grounds before tamping. By transferring ground coffee beans into the GDT, and giving the grounds a quick shake with the lid closed, then releasing the grounds into the portafilter with the plug gives a more even distribution of grounds in the portafilter. Replace your dosing cup and distributor with this all in one tool.

Why is a Blind Shaker the preferred distribution tool?

Recent studies highlight the technique of utilizing a blind shaker tool for shaking coffee grounds yields a higher extraction compared to alternative distribution techniques like the WDT tool or other distribution tools. The unique design of a blind shaker tool, equipped with a plug, ensures a uniform flow of ground coffee into the portafilter from the outer edges inwards, minimizing the occurence of grounds accumulating in any specific corner of the portafilter.

Is there a 54mm Blind Shaker for Breville portafilter users?

Presently the blind shaker tool is only available in 58mm but can be adapted for use with 54mm Breville portafilters by employing the SingleDoseBrew 54mm Portafilter Funnel for Breville. This conversion funnel seamlessly transforms your 54mm portafilter to a 58mm edge, enabling compatibility with 58mm accessories like a blind shaker tool for a perfect fit.
