Grinista

Grinista, presented as a Kickstarter project, tries to fold several pieces of a home coffee setup into a single machine. The maker describes it as an all-in-one grinder built around precise weighing and fine-grained adjustment, intended to suit a range of brew methods and bean types.

What the maker highlights

• Built-in scale: an integrated weighing system that, the maker says, measures beans precisely for anything from a single cup to several.
• 48 grind settings: adjustment runs from 0 to 16 with finer steps within each level, covering methods from espresso to French press.
• 64mm flat burrs: large flat burrs that the maker says deliver uniform, precise grinding.
• Automatic powder removal: clears grounds from the burrs and outlet, keeping retention to 0.1g or less according to the maker.
• Adjustable RPM: motor speed variable from 600 to 1800, which the maker positions as a way to match bean type and roast level.
• Compact metal body: a space-saving design with a metal exterior meant for kitchens and café spaces.

Speed as a variable

The adjustable RPM is the most unusual item on the list. Rather than a fixed motor speed, Grinista lets the user pick anywhere between 600 and 1800 RPM, with the maker suggesting that tuning speed to the bean and brew method helps bring out flavor.

Paired with the low-retention claim and the integrated scale, the pitch is a grinder that cuts out separate weighing steps and cleanup. The maker frames Grinista as having the potential to set a new standard for home grinders; how it performs in practice is not something Modern-G has assessed.
