Excellent Bellows to Reduce Retention on Baratza Encore ESP
I bought this bellows to reduce retention in my Baratza grinder, and it works exceptionally well. It fits perfectly on the coffee bean hopper, and the lid also fits without any issues. The material feels durable and well-made, so I expect it to last a long time. I consider this an excellent accessory for the Baratza Encore ESP. When grinding for espresso, retention can reach around 0.5 grams, but with this bellows, and using the RDT technique, it’s reduced almost completely. If you want more consistency and less coffee waste, this is a great addition to your setup.

Perfect - Perfectly clears my grind retention!
Even though this particular Aieve model is made for the Baratza Encore grinder, it works *perfectly* on my Capresso Infinity grinder (air-tight fit is important). Even though the groove in its bottom ring is just a few mm wider that would fit my Capresso hopper, the *inside* of the bottom ring just so happens to *perfectly* fit nice and snuggly over my Capresso hopper. It works fantastic. I love my Capresso grinder (which has amazing grind quality for an inexpensive grinder), but it does have a pretty significant amount of grind retention. I completely flushed out all previous grounds then tested my new Aieve Single Dose Hopper. I quickly pressed down 3-4 times right at the end of the grind. It completely flushed the retained grounds. I suggest pressing down sharply and releasing upward slowly 3-4 times just after your dose of beans finish grinding, while the grinder is still running. Releasing quickly on the upward strokes tends to pull a very tiny amount of fines and chaff up into the hopper, so I go down quickly and up slowly. I'm extremely pleased with this and that I'm no longer agonizing over upgrading to a much more expensive zero-retention grinder. Highly recommend for the Baratza Encore and the Capresso Infinity. I've also purchased Aieve's larger model (several color choices) for the built-in grinder on my new Breville Baratza Pro espresso machine. I got the gray one; cool looking; looks like it's made for it.

Great accessory
I never expected the baratza ESP could have this option, like other smaller grinders. Works great! Very affordable.

Excellent Add-On Product
I love my Encore grinder. Sure there are pricier, better-performing grinders on the market. But for the price-to-performance ratio, the Encore is top shelf. One issue with gravity-fed burr grinders in general is the loss of grind. You put some number of grams of beans into the grinder, you get some smaller number of grams out. Those extra grams are hanging out in the mechanism of the grinder because the grinding process creates static cling and the grinds stick to it. And those orphaned grinds stay in there getting stale, which reduces the quality of the next day’s pot. This bellows very nicely pushes most (but not all) of those orphaned grinds into the reservoir to be brewed. It’s as simple as that. It’s easy to detach and wash this all-rubber device. It fits well over the top of the grinder, and the grinder’s existing plastic top fits well over the device. The only small complaint I have is that bits of grind get knocked upward into the corrugated sides of the bellows. So it does need to be removed and cleaned every few days or so. But running it under the sink with a soapy sponge is a quick, easy process.

Is so so
Does not fit snugly and is easy to knock off. Does not work well on a counter under cabinets. The puff is a bit aggressive, and coffee ends up on the counter. I have found that lifting and tapping down the lid that comes with grinder works ok.

Item title is misleading - product description is acurate - product is good
The product title "single dose hopper" is misleading. You are not getting a single-dose sized hopper with attached bellows. You are getting a bellows to attach to the full-sized hopper that came with your grinder. If you read the product description, it states that it is a bellows to attach to your hopper. I am partially to blame for not fully reading the description; however, the manufacturer is also partially to blame for not providing a clearer product title. I would have titled it "Bellows Attachment" with a subtitle of "single dosing use". As for product quality. I am very happy. It fits perfectly with the hopper and hopper lid. I wish it would be a bit more secure, but I think they went with ease of attachment. (It would have to be harder to attach in order to make it more secure). It does its job well; it pushes grounds out that would otherwise be retained between and below the grind burrs.

Perfect solution to Baratza Encore’s retention issue
The Baratza Encore is a beloved entry-level home coffee bean grinder. However, it’s primary issue is it retains some of your grind inside. It’s essentially a grounds gremlin. Yes, you could spray your beans with a small spritz of water to limit retention or clean it with the brush, but let’s be honest, not everyone wants to do this on a daily basis, and you shouldn’t have to. This is a clean, simple solution that fixes the need to do anything more than a couple pumps after you grind. It adds minimal bulk, feels surprisingly well made, and matches the aesthetic of the Encore as if Baratza has made it themselves. I’ve found that 99% of the time, I get exactly the same grams as what I put in. On occasion it’ll still retain about .1 grams—but that is common with nearly every grinder and is quite negligible. My advice for a future version of this product is to use a material that will collect less dust from coffee grinds and general room dust. As you can see in the photos it does collect a bit. Static tip for Encore: I’ve found that after you grind your beans, if you leave it in the container for ~20sec, it will eliminate nearly all static, and you won’t have to use any spritz of water on your beans before grinding.

Funciona a la perfección. En mi caso tengo una Baratza encore esp y me ha ayudado a sacar toda la molienda y se no queden residuos dentro del molino.

Does exactly what it should do, and it’s affordable. It does however add 2 1/2 inches to the height of the grinder, which may be a problem for some .

I bought this for my Baratza Encore ESP. It fits perfectly and works exactly as described. Very happy with the purchase.

We use our Baratza Encore ESP as a single shot grinder. We weigh our 14g of beans in each time. We noticed clumps would sometimes come out at the end. I purchased the bellows and was amazed, at the end of grinding we can get between 0.5-1g of coffee out by using the bellows. So hopefully no stale grinds sitting in the grinder. Did look at a single dose hopper but this option looks and works great. Ps doesn't fit well upside down!

When buying a product like this, you'd expect it to be fairly uniform upon opening the box. Not so--the bellows I received are very clearly not that round and a bit flat on one side. What this means is that they don't compress evenly and a gap forms on that flat spot. It's not good. I'm hoping another one can be sent out as a replacement.
