Moccamaster Cup One

5-YEAR UPDATE: The machine is still going strong. I descale with white vinegar every 80-100 brews (I use the filter box as a guide; once I've finished the box of filters, I know it's time to descale. I've never opened it up to clean the interior, although it would probably be a good idea to do so now. The warranty is up, so I feel comfortable taking it apart to see how the guts have held up in these 5 years. If I remember, I'll take pictures and post them here. I use 3-stage filtered tap water, and I've never noticed an unusual amount of scale buildup. I've also tasted my coffee alongside distilled water with 3rd Wave Water mineral supplements, and haven't noticed much of a difference. This machine can handle 1-2 cups of coffee per day for 5 years, I can confirm. This machine will keep its 5 stars. If I could go back and do it again, I *may have chosen a batch brewer that could brew more than 1 cup, for all the cases where I've had to make coffee for visitors. But for most days of the year, it's just me drinking coffee in my house. For times where I need to make coffee for visitors, I use my 1L French Press. My Baratza Encore on setting 10-14 works great, yielding 10-12 oz of brew in 2:30-3:30. My next drip brewer will probably be a Moccamaster again. Love mine! UPDATE: 2 months after my original impressions, I've gotten into the groove of using it and how to get the most out of it. I've concluded that setting-and-forgetting this machine sufficiently renders great coffee without altering anything out of standard coffee making procedure. The damp coffee grounds left after brewing do indeed still form a cone-pyramid shape, but I haven't noticed hardly any difference from when I stir the grounds during brewing 2-3 times vs. not touching it at all. This bumps the machine from 4 to 5 stars. This is the best single serve machine on the market. Now read my review below and keep in mind what I just mentioned. I'm going to be rather critical of this machine since I spent a pretty penny on it. But if this gets 4 stars, 99% of other auto-drip brewers probably get 1-2 stars. This machine is fantastic. I've put about 15 cycles through it, and the ones where I measured temp, they all came out to ~198-200F, and all went thru the brew process of 300g/10oz water (medium fine grind) in about 5 mins total, from flipping the switch to the last drip, 5:30 at the longest. So it does what it says it's supposed to, which is great. A few design features confuse me. The lid that sits atop the reservoir and drip cone sits a little precariously (it wants to tip if you touch the cone side). This is minor, but I feel like maybe a hinged joint on the reservoir side and the cone side would be more robust. Additionally, the drip spout is a simple U-shaped tube (longer on one side). I wonder why Technivorm didn't follow the design of the other higher volume brewer models and design a shower-head design instead of just a dripper that drops water right into one spot the whole brew process instead of the even showering you see in bigger models. I don't think this would necessarily lead to better flavor, but from what I know about pour-over coffee, a more even wetting of grounds is always better. The grounds do seem to all get wet, but once dry, they form an inverted cone/canyon once the brewing is done. I stir the grounds/water after about 30 seconds to hopefully combat this possibly negative effect. I'm too fiddly to resist, but the coffee tastes great either way. The reason I included this tidbit is that if you pay this much for a brewer that is supposed to be mostly autonomous, there should have to be minimal interference for good coffee. This is probably why I'm putting 4 stars instead of 5. If someone provides me with enough compelling evidence that this doesn't matter, I'll change it to 5. The coffee is excellent. Without the cup preheated, and waiting about a minute after brewing ends, the coffee is at the perfect temp for drinking. The mug is nice as well, and the filters seem to be flavorless/neutral. This sits in my office and gets to brew 2 * 10oz cups for me daily (Onyx Geometry, Colombia/Ethiopia blend is great through this). If you only plan to brew for yourself, this machine is perfect, because if I brewed 2 cups a day through a machine with a thermal carafe or burner, that 2nd cup would be stale/lukewarm 6 hours later, I almost guarantee it (even the good Zojirushi carafes/warmers cool off after about 4-5 hours). So it's a quick, fresh cup on demand. DO NOT buy this if you plan to brew for multiple people or an office. Grab one of the bigger volume models.

I hesitated to buy this because of the clogging reviews, but went ahead and tried anyways, as it was one of the only coffee makers with a long enough cord for my office. I've owned the Cup-1 for about 10 months and have made over 120 cups of coffee and have not had the clogging issue while making coffee. I have been able to replicate it, though. The hole is quite small, and when water with a little bit of residue dries, it can clog the hole. I noticed this when I was cleaning it one day - no water would drain even though it was free of grounds. The solution: just use the included needle thing to clear the hole just before making coffee. For the sake of consistency (so I remember), for each cup, I poke the needle through the bottom of the hole towards the coffee filter immediately prior to pressing the on button - even after water and coffee are added. For those worried about use in the office - I am lazy and typically let the old grounds sit in the coffee maker until my next cup the next day. The grounds are dried by the time I remove them. I just dump the grounds out, give it a quick rinse in the sink with a bit of soap occasionally, and remember to poke the hole with the needle. If you are really worried about overflow, just place a baking tray under the coffee maker. I prefer the Melitta #2 filters over the included Moccamaster #1 filters. The smaller #1 filters can occasionally fold over if you don't sufficiently press the filter in. This has never resulted in overflow for me, but has resulted in most of the water missing the grounds and an extremely weak cup of coffee. I have owned a KGBV Select 10 cup maker for a few years, so I will compare to that. The coffee from the Cup-1 is better tasting in my opinion, which is probably due to me using a bit higher coffee to water ratio. The consistency is the same as the KGBV - basically the same great tasting coffee every time. The lid is just as annoying as the KGBV lid, but you get used to it. It does make cleaning easier. I wish there were a better place to store the needle. I should 3D print something, but for now, I just have a piece of cardboard taped to the side of the coffee maker: ugly, but works well.

This machine is the biggest piece of crap. I have only had it for 8 months and it clogs continuously even though I use the needle tool they provide to unclog (which is sort of ridiculous anyway considering no other pour overs have to have this tool). It doesn’t drip through to the cup and instead floods the funnel and creates a giant mess all over the counter which then requires way more time cleaning than the 4 mins it is supposed to take to brew a cup. I emailed customer service and got no response. DO NOT BUY.

Es sin duda alguna una maquina robusta, sólida y con calidad excelente. Produce café con excelentes características y la temperatura exacta en cada taza. Recomiendo este producto ampliamente.

I am quite pleased with this, now. At first I was disappointed — the coffee was too weak for my taste. But I experimented and eventually found a grind setting and an amount of coffee that gives me the kind of strong coffee I like. I haven't had any trouble with the little hole clogging. I wash the basket immediately after making my coffee and occasionally stick a dental brush in it. I always wet the filter with hot water before making coffee so that gives me a chance to check that water is flowing from the basket. The tiny hole is essential to the process: A bigger hole, or more holes, would result in weaker coffee. This was extremely expensive (even though I bought mine from the warehouse) so I hope it lasts several decades. It's nice to be able to make a good, single cup of coffee! --------------------- It's been over a year. This is written in September, 2025. Still no problems with the little hole. Wash the basket, people!

This thing makes an excellent, consistent cup of coffee. All you have to do is bring it the right beans and it does the rest. It's a perfect solution for people who want the freshest, hottest cup of coffee every time, not that lukewarm second cup that you get with a big carafe. The only downside is the filter sometimes gets jammed, so you need to make sure it's clear before you brew.

Excellent unit, great quick one cup unit and nice and hot! highly rated in the Netherlands too!

I got this for my office as I have a full-size Moccamaster at home. The quality and taste of the coffee made with the Cup One is just as good as the regular sized machine. It consistently brews a cup in just over four minutes. I have had multiple other one cup machines that use pods or discs and none can produce coffee to the caliber of the Cup One.
