Coffee Grinder Single Dose Hopper for Eureka Mignon Grinder 2 in 1 Function Coffee Grinder Accessories Hopper Hand Pressure Silicone Bellow to Clean and Collect Coffee Grounds

Simple installation, effective in converting to single dosing
I considered the single dose model of the Eureka Mignon, which has a bellows very much like this and is at a 30 degree angle. That one was quite expensive. Getting the very attractively priced Whole Latte Love exclusive Mignon Facile (Exactly like the Silenzo only without the grind timer, for like $100 less) plus this single dose hopper plus 3D printing a perfectly fitting stand that puts it at a 30 degree angle basically got me something very close to the single dose model for a whole lot less money.I prefer single dosing as I like to keep the beans stored in a vacuum canister rather than leaving some in a hopper on top of the grinder to oxidize. I can weigh out exactly what I need, and the reality of this single dose hopper is that it does actually effectively blow out most of the residual grounds. Without it, retention would be somewhere around 1.0-1.3g, but this gets you to somewhere under 0.3g retained. What you put in is virtually the same as what comes out. With the last tiny bit of what was retained last time being replaced by the small retention this time, you should pretty much land on the dose you were expecting.You’d think that even with higher retention that “old retention out / new in” gets you close as well, but keep in mind that just less than 0.3g being retained is far less stale oxidized grounds to be mixed in with your fresh dose rather than 1.3g or so, which is more significant. Also, less retention means that there is less opportunity for variability in how much ends up in your dose. Having much more left in the burrs just increases the possibility that a different dose results than expected as it’s more to possibly come out next time or maybe it retains a lot more from shot to shot. Anyway, one less variable, or at least minimizing one of them.My only complaint is that this thing is probably slightly more expensive than I’d have expected for what it is, which is a not very complex few pieces made from materials that aren’t super costly, but I’m guessing it’s one of those things where there are design and development costs and maybe not a massive volume to be sold so the unit price ends up needing to be higher than you’d figure to get them to a point of making something from it. Fine. For me it’s still well worth it.

Eureka espresso grinders need bellows like this. This is a good one, with a minor issue.
If you have a Eureka grinder you know. They are arguably the best espresso grinders for home use. But they have a strong tendency to get clogged up, because of a little metal screen at the top of the chute. If you don’t blow it out with a bellows very frequently, fine grounds accumulate and clog it up. You can disassemble and clean it but who wants to do that? With a good bellows you can blow the grounds through. It’s best to do that after every use.This one has four collapsable stages, which is better than those with 2 or 3. It works great.Some reviewers have noted some problems, and initially I did, too. The main problem is that it doesn’t come with any instructions and it is possible to use it in multiple ways. Only one of them works right.If you try to leave it in place and take the top off to add coffee, you’ll be disappointed. The top is hard to remove, while the whole bellows tends to fall off the grinder when you do. It comes with a big black rubber band. Perhaps that is meant to hold the bellows in the grinder? Who knows. Maybe that’s meant for use with another brand of grinder? The paperwork that came with the bellows indicates it’s for several different brands of grinder, not just the Eureka Mignon.The way this device works properly is to remove the bellows every time you add beans. Don’t pull the top off, and don’t try to make the bellows stay in the grinder. Forget the rubber band. It’s very simple and easy.When you add beans with the bellows removed, there’s only enough space for about one dose. That’s OK.

Very nice and great addition to your grinder
It’s a great upgrade to your grinder, the metal cap feels premium and the bellow Is a good quality.My retention has dropped from almost 1.5-2 grams to less than 0.3 grams.I just wish if there is no branding on the metal plate it would have been nicer.

Bought this to use with a Eureka Mignon grinder – with timer but not the digital screen version. It is a very tight fit, but goes in with a bit of force. The bellows fit well and stay in place and the cap fits well too. I do not have the issue that some report of the bellows coming loose. The cap needs a couple of firm pumps and it cleans the grinder out brilliantly. The EM is not known as a high retention grinder so single dosing was my main purpose. I did consider units with a clear hopper, but went for this partly because there is no anti- popcorn screen as in my experience beans just get trapped on them. The fall onto the burrs is steep and pop-corning is not really an issue with this grinder. With an 18 gram bean dose and one pump on the bellows, I get 17.8 grams of espresso grind out, or 18 grams out if I use a minuscule spritz of anti static water. The item is well made – I did not want cheap printed plastics. The bellows look to be high quality as is the (branded) lid. Other buyers comment that they don’t know how to fit the rubber band. I think it is a wrist band – and there is no way I am wearing a branded but of rubber. Eureka do of course sell their own version of a single dose hopper in plastic or (insanely expensive) glass and their own bellows. But it is more than double the price for what is in essence just a funnel. I recommend this item. Price I paid was circa £32.

Amazing, it fits perfectly to my Eureka Mignon Specialita.

Juste génial, il fit parfaitement avec mon silenzio !!
