KRUVE Sifter 5pcs Coffee Grinder Measuring, Graduation, Refining (Black)

-color bleeding, I bought the black one and the color bleed on my hand , not safe for beverage process -lid was too tight, doesn’t fit well with sifter body, hard to open

This is pretty amazing, but it showed how very much *not* consistent the grind is from my Baratza Encore grinder. I had no idea. Using the 800 and 1100 screens, which is in the ballpark range for pour over, I get roughly a 26% yield of usable ground coffee from the first run through the sifter. That’s with experimenting first in adjusting the grinder to get roughly a 50/50 split between too large and too fine. Though as someone else pointed out you can regrind the too large grains and re-sieve them and after a few runs through I can then get about 22-24g of ground coffee from 50g of beans. So this thing isn’t going to save you money, that’s for sure! However the resulting coffee from my Kalita Wave pour-over coffee dripper is certainly a good bit better, so it’s worth it to me. Though it also makes me want to buy a $1000+ grinder to get a more consistent grind to start with. Oh the hobby… lol. Even a grinder like that I’m sure could still benefit from this sieve, though, as there is still going to be inconsistency, just less. As far as ease-of-use, I had no issues with it once the screens are properly in, however I do find getting them clicked in to be fairly tricky. Particularly in the bottom one. But I think with practice that will get easier. Overall a well designed device and I do highly recommend it. And … I just ordered the rest of the screens so I can fine tune the grind more. But if you are making pour over you can certainly just use the included 800 and 1100 screens (the normal range for pour over is 700 to 1200) and get better coffee right out of the gate.

Muy buena calidad, llego dentro del tiempo previsto. Estoy contento con la compra

The Kruve sifter is designed to solve a common problem: the inconsistent size of the coffee grounds you get out of a typical coffee grinder. That might not sound like a big deal but it is. Coffee grounds impart their flavor differently depending on how large they are. Small ones brew fast and can turn bitter quickly, while large grounds brew slowly and don't contribute much flavor at all unless you brew them a long time -- and by that time the small grounds have ruined the coffee with their bitter taste. So that's the problem: different sizes of coffee grounds that need different brewing times, all mixed together in the coffee you're trying to make. There's no way to choose the right brewing time. I was shocked how inconsistent my grinder is: lots of tiny bits mixed in with very large ones. And my grinder is a highly-rated burr grinder, one that you'd expect to do a good job. But it's still not good enough because my coffee had a bitter taste. The culprit was those tiny coffee grounds. Even setting the grinder to "coarse" did not make them go away. But filtering them out with the Kruve works like magic. The sifter removes the grounds that are too small, separates out the ones that are too big (so you can grind them again, a little smaller if you want), and leaves you with the ones that are sized just right. You can see the difference just looking at them. It's not a lot of extra work to sift your coffee grounds. It adds about three minutes once you get the hang of it, and the results are worth it. Now I'm drinking smooth, delicious coffee. No more bitter flavor. You do throw away the small grounds (called "fines") which seems wasteful at first but it's made up for by the fact that you can re-grind the "large" grounds to get them to be just the right size and brew more efficiently. So you lose a little on the small end but you get it back on the large end, for no net loss. I'm using the same amount of coffee beans per pot that I was before sifting, and now my coffee tastes so much better.

I like it, I use it. I used it to help dial in my super expensive hand grinder for pour over. I'm not convinced that the fines are what is hurting your cup. I think it's more likely that the chaff present in the trendy coffies of the day are having more of a bittering effect. Anyway it works, my screens fit, stay put, and I probably won't be using it a lot, but I'm glad I have it.
