Kruve Twelve Sifter

Do you know if your coffee grinder is doing its job properly? Can you ascertain the quality of your coffee grinds, whether by touch, sifting the grounds through your fingers, or simply by sight? Are the ground particles uniform in size, allowing for the best extraction? In short, is your grinder helping you make the best cup of coffee you can brew?

If your answer falls anywhere on a scale of “No idea” to “What the heck are you talking about?” then the KRUVE Sifter Twelve is the tool for you.

The Pitch

The KRUVE Sifter is a compact device for determining the optimal size of ground coffee for every brewing method. Anyone who takes their coffee seriously can benefit from sifting coffee grinds with the KRUVE Sifter.

Unboxing Kruve pre siftingThe KRUVE Sifter’s components are a two-tiered set of triangularly-shaped compartments. A set of 12 sieves comes in micron densities from 200 µm (the neighborhood for espresso) to 1,000 µm (french press territory). The photo-etched metal sieves snap snugly into place in two of the compartments, which are housed between a bottom tray and a lid on top. The KRUVE Sifter kit also comes with a bamboo sieve holder to keep everything organized.

Simply grind 50 grams of whole roasted coffee beans, dump the grinds into the top compartment of the KRUVE Sifter, then gently shake the KRUVE Sifter for about a minute. Boulders—the oversize and chaffy bits—will remain in the top compartment, and the dusty particles (aka super fines) will separate into the bottom tray.

When this distribution is achieved through sifting, you know your grinder is calibrated correctly and you can proceed to pour-over, drip, espresso, or any brewing method in between—Chemex, AeroPress, Ratio—in full confidence that your grind size is dialed in for optimal extraction.

The KRUVE Sifter has applications for coffee professionals, too. It has obvious appeal for baristas of all levels, from those who are just beginning to learn the craft, to those who are throwing down in latte art competitions. In fact, several international barista champions have used the KRUVE Sifter along their path to victory.
