Kruve uses a tiered sifting system to solve the problem of uneven grind size. Two tiers and up to twelve interchangeable sieve provide up to sixty-six possible grind sizes. The tool is simple to use—just pour in the grinds and shake to separate out the grinds that are too large or too small.
The Kruve Sifter also allows users to get much more specific than fine, medium, and coarse. Each sieve is defined by particle size measurement, providing micron-level precision. A brew guide provides recommended particle sizes for each brew method, giving a starting point for getting favorite recipes dialed in.
“Many have tried to perfect the grinder, but we perfected the grind,” said Kruve co-founder Mark Vecchiarelli in a recent press release.
The coffee sifter is not meant to replace a poor grinder, but to enhance even the best grinders on the market. It has also been employed as a calibration tool in kitchens and coffee shops around the world.
