Coffee Grind Refining System

Many have tried to perfect the grinder, KRUVE has perfected the grind

The KRUVE Sifter Can Make Any Coffee Taste Better. With micron-level precision, it takes the guess work out of grind size.

The KRUVE Sifter solves the problem of uneven grind size and arbitrary measurements. With two tiers and up to fifteen interchangeable sieves, the KRUVE Sifter delivers 105 possible coffee grind sizes at the precise micron range of your choosing! This means you get a truly uniform grind every time you brew and that, in turn, means better tasting coffee.


Not only do grinders change and wear over time, but no two grinders are alike. So, if you want to achieve a truly reliable coffee routine, you need to have a properly calibrated grinder. Use the KRUVE Sifter to determine the grind settings you should actually be using


Imprecise grind measurements like “fine, medium, and coarse” or vague comparisons like “sugar or sea salt” are not helpful. Proper brewing requires accurate measurement. With the KRUVE Sifter, you can confidently create and replicate recipes using objective measurements.


Your brew measurements are calculated down to the second, gram, and degree. Now, you can refine your grind down to the exact micron range of your choosing. With two tiers and up to 15 sieves, you can take advantage of 105 possible grind sizes. Add to that, our sieves are etched, which means sifting is faster and more efficient.
