Look no further
UpdateExecutive summary: this thing is great, get one!I had left a rather negative review. The canister I received would leak its vacuum out, then automatically re-vacuum. I was convinced that this behavior was intentional because they knew that the thing leaked, and I was appalled.OutPeak saw my review, contacted me and said no, no, no, that is definitely not the case. They offered me a full refund (I was past my return window) and asked me to give them another chance. Well, I _do_ really like the product's fit and finish, I just wanted it to work, so I replied that if they felt that my unit was simply defective, I'd rather exchange it than get a refund.They promptly sent me a replacement unit. I've been using it for three days now and it has operated flawlessly!Apparently my first one was indeed defective, so I was WRONG and am now eating my words! I'm leaving the original below so you can see exactly what I'm eating.In retrospect I should have contacted OutPeak, but in my defense, I've had very, very few positive experiences with customer service departments. That's another point to note – I'm very impressed with OutPeak's customer service and a company that stands behind its products. TBH I would have given them another two stars just for reaching out!Some people get agitated when they receive defective products. Really I'm ok with that; while it's not ideal, we quite simply don't live in a perfect world. OutPeak being an outstanding company is more important to me than 5 stars, and if I have a need for any more vacuum canisters I will absolutely get another OutPeak one. If you're reading this, you're looking for one right now. I encourage you to stop looking and get this one!- - - - -I don't get it. The entire point is that it's supposed to keep the contents under vacuum. If my design team came to me with this as-is, I'd tell them to go back to the drawing board and see me when they had one that actually... kept the contents under vacuum.What they did instead is set it up so that it automatically re-vacuums when enough air has leaked in to trip it. So I know I don't have a defective unit, they designed it that way.What's the problem, you ask? Well, any time you walk by it, you can SMELL the contents. That means that it's leaking the scent, the moisture, and the flavor. By design.Another, more subtle problem with this faulty design is that you'll need to remember to charge it occasionally, because all of those automatic re-vacuumings are running down the battery.Mind. Blown.

Solid vacuum canister overall, but the 0.5l version is much too small for practical use
TL;DR: The vacuum feature works well to keep coffee fresh for a decent amount of time, which I think is the OutPeak's major win. But its major drawback is that what they call the 0.5L size (the one I bought) is considerably smaller than other canisters that offer similar capacities. It's too small to be at all practical for daily coffee drinkers. If the 0.5L I got barely fits 130g of dark roast, anything under 1L isn't practical. The vacuuming isn't as strong as on the manual Fellow Atmos I own, but on the plus side, the Atmos doesn't auto-pressurize when it detects a vacuum loss, which the OutPeak does, making that its major selling point. I really wanted it to be the end-all of coffee canisters, but unfortunately, due to its capacity, it isn't. Due to the tiny, impractical size, especially when my Atmos (with a 0.7L capacity) can hold over 250g of beans and still have room to spare, I really leaned into giving it just 3⭐. But because it does such a good job, because I got it on sale for $23, and because I imagine had I gone for the 1L one I'd be very satisfied with it, in the end I'll give it 4⭐—if nothing else, because it does keep beans as fresh as on day 1 for a decent amount of time.PROS:🥳 Keeps coffee fresh for a decent amount of time🥳 Automatic vacuum feature is simple and easy to use🥳 High-quality materials, with no plastic in contact with beans🥳 Bonus small canister and scoop are nice touchesCONS:😩 The 0.5L model is WAY too small (barely fits enough coffee for about eight 15g espresso shots)😩 Vacuuming isn't as powerful as manual models😩 Price is too steep for the size (my MUCH bigger Atmos cost less than this tiny canister costs when not on sale)DETAILED REVIEW:NOTE: I've uploaded a video alongside this review that shows the correct workflow I mention later on in my review in order to avoid it from trying to re-pressurize while you're using it (as I've seen several reviews mention this a "bug", while it's not). It also shows how the thing actually sounds. Check it out for a more visual showcase of what I write in this review. Also, a disclaimer: in one of the photos I upload I pose my grinder's air blower next to the OutPeak as a size reference, it doesn't come included in the box. The other two items in the photos do. 😊CAPACITY:Let's start with the obvious: the size of this canister is far too small for serious coffee drinkers. It holds only about 130g of dark roast beans (meaning a little more for medium and light roast), just enough for 7-8 shots of espresso. I typically use 15g per shot on my Flair Pro 3, and we usually drink 2 cups in the morning and I drink 1 in the afternoon. In our case, this tiny canister barely lasts 2-3 days. So, for anyone who drinks more than one cup of coffee a day, this canister is impractical. There's no need to spend this much on storage for a week's worth of coffee. I believe fancy coffee storage is only necessary for beans that won't be touched for 7-8 days. And with this small canister, you're opening and closing the lid daily, essentially negating most of the benefits of vacuum storage. If you're a daily drinker, you'll either need to buy two of these tiny canisters or get the larger 1L one, because even the 0.75L still is not going to be big enough for 250g, if we extrapolate from the 0.5L's capacity. Why have they chosen these lower, impractical sizes? I think starting with the smaller canister having at least a 250g capacity would've been a much better choice.So why did I buy the small one, then? Well, that's my main gripe: I wasn't expecting it to hold so little coffee… As I mentioned, my 0.7L Atmos fits well over 250g of dark roast beans, which is perfect for a week (or more) of daily espresso. A quick Google search shows that "250 grams of coffee beans is roughly equivalent to 0.375 to 0.5 liters". So, all things considered, I had no reason to believe a 0.5L canister wouldn't work for my needs—an OutPeak 0.5L clearly doesn't.VACUUM FEATURE:The vacuum feature is solid and works well to keep your coffee fresher for longer by creating a low-pressure environment. James Hoffman's video comparing different canisters concluded that only actual vacuum canisters made a difference. There's more nuance in his video, but this is roughly the material point. He tested manual vacuum canisters (the Atmos among them), but the OutPeak should rank similarly. Displacement canisters, like Airscape, though perhaps more professional-looking than vacuum canisters, at least than the OutPeak, imho, were only slightly better than just using an airtight container.In practice, the OutPeak has given me excellent results. While my Atmos may create a better vacuum, it loses it over time and can't regain it automatically, unlike the OutPeak. After a week of storage, I've found my beans still smell as fresh as when I first sealed them, and the resulting espresso from my Flair tastes just as fresh as when I used freshly defrosted beans—even the workflow and profiling on my Flair feels exactly like with freshly defrosted beans rather than like beans that have been in a container for a week or so. So, the OutPeak definitely delivers top-notch storage, in my opinion.From the first time you seal it, the vacuum works well, and you can hear the motor kick in. It doesn't take as long as I expected for the electric air pump to reach inner pressure, which made me skeptical at first—but the results speak for themselves, I guess. As long as you don't open the canister, your beans should stay fresh for a decent amount of time. Of course, opening and closing the canister daily will prevent beans from staying fresh, so it's best to minimize how often you open ANY container. I recommend opening and closing the container only once a day to preserve freshness. In ideal conditions (i.e. not opening the canister), I found it keeps coffee as fresh as on day 1 for at least 5-7 days, which is already impressive. (Though I haven't had a chance to test it for longer, I think there's really no real-world reason to do so on such a small canister, because whoever is keeping 130g of coffee sealed in a canister for longer than a week is a person who probably doesn't taste the difference between a day 7-15 bean and a 3-month-old supermarket bag, imho.) Having said all this, when you press the outgas button to open it, you don't always get the strong rush of air you'd expect from a manual vacuum canister like the Atmos*, so I'm not sure how much air it's really removing and how comparable it is to, again, the Atmos, if you were to manually degas it a bit every day at least. At any rate, the freshness of the beans speaks for itself.* This may seem disingenuous, or maybe an exaggeration, considering that in the video I uploaded, you can hear a decent amount of whooshing. However, I'd say: (a) I've increased the audio levels in that video so everything is more clearly audible (and I also reduced the background noise, btw); and (b) I'd also say that the depressurization recorded in the video is one of the strongest I've seen, so I suspect it happened fairly soon after an auto-pressurization, since it occurred about a week after the canister had been closed. This is corroborated the very next time I opened the canister the next morning to brew a cup and the thing made a very tiny, barely noticeable whiff of air, as a pose to a whoosh.FUNCTIONALITY:A lot of reviews complain about something that, in my experience, isn't really a defect but rather part of how the canister works. The OutPeak has an ON/OFF button that, when engaged and the device turned ON, essentially tells the device to pull a vacuum right away and, then, to do so again every time it senses that the pressure drops.** Clearly, when it senses said drop in pressure, there's a 20-30 second delay before it re-engages the vacuum. This delay prevents the canister from automatically pulling a vacuum as soon as you depressurize it to get coffee. But as 20-30 seconds is in practice too little time for the weighing process, especially if you're taking out more than one dose, it often tries to start pulling a vacuum again with the lid off the canister. This is the "issue" people are complaining about. So, what's the solution? When you're going to open the canister to get coffee, just press the ON/OFF button to turn the thing OFF… The LED light will flash a couple of times, which means it's turning off. You can take as long as you like; it won't try pulling a vacuum. Once you're done, just close the lid and press the ON/OFF button again and the above-mentioned process will start again. It's simple and works perfectly.**As an aside: it'd be great to know how it senses its pressure has dropped and needs to pull a new vacuum, and especially exactly it senses as a pressure drop, because I feel like it gives a lot of leeway as to what is a true vacuum and just normal atmosphere. For instance, sometimes the canister produces no sound when pressing the degassing button, which makes me think it's close to 0 pressure, i.e. at the same pressure as the outside, and, probably, close to needing to pull an auto-vacuum. But surely it should auto-vacuum way before that, right?Which brings me to my recommendation for OutPeak, if they ever read this review: While the automatic vacuum feature is solid, I do think it could be improved. It would benefit from a function that pulls air out once or twice a day by default, rather than only waiting for what I assume is a sensor to detect that the canister has lost or nearly lost pressure. This would ensure the canister stays as pressurized as possible, rather than letting the pressure drop below the ideal level before it kicks in to repressurize. As the pressure gradually tapers off, the beans are increasingly exposed to the atmosphere, which isn't ideal for preserving freshness. Constantly ensuring top pressure would effectively solve this, keeping the beans in an optimal low-pressure environment at all times.For now, beans stay super fresh for at least a week. I think if I were to leave them in there for a month, most likely I would start to smell and taste the staleness at least creeping in. But if this thing would constantly suck out a bit of air, like when you plug your phone to keep it constantly at 100%, it may be able to keep beans fresher for much, much longer.DURABILITY:As for durability, I'm skeptical. The canister is made of high-quality materials, but its electronic components are a concern. Once the vacuum feature breaks, it's just a costly container. The vacuum system seems fine now, but I'm not sure how long the motor or battery will last. Both of those are the weak links; the battery being perhaps the weakest and probable first to go, and I'm not sure if it would work while plugged in with a dead battery. The motor probably isn't exerted too much with the light vacuuming it does every so often (I've really only heard it kick in once when it had to, but that's because I was standing next to it making coffee during that week-long test), so I don't think it will die soon, unless of course it has some sort of manufacturing defect. But there's no real way to know how long a thing like this will last. Again, something like the Atmos, being entirely manual, is likely more durable in the long run.Would I sacrifice the auto feature for the longevity of the Atmos? Well, let's put it this way: I plan on continuing to use my Atmos as my daily driver; this one, if I ever get a suitable capacity, can be for longer storage.BONUS INCLUDED TOOLS:I don't want to nitpick, it being a gifted horse an all…, but the bonus small canister included for daily doses is perhaps as frustratingly tiny as the tiny 0.5L canister itself. It only holds about 28-30g of beans, which isn't generally enough for even two "normal" shots of espresso for most people. I say "normal", because I use 15g doses per shot on my Flair, so I can cram 30g inside and have 2 shots at hand every day. But most people dose 18g+ of beans per shot of espresso, and they will only be able to hold 1 extra shot there. Because I'm certain this is meant to be a dosing canister that lets you only open your vacuum canister once a day to avoid over-oxygenating your beans, then I have to say it doesn't really fulfil its intended purpose. It really should be able to hold at least 2 "normal" espresso shots. It's a nice gift for someone who only drinks 1-2 shots a day, and it's a good quality little aluminum canister, but it's impractical for multiple cups, and that makes me think what's the real purpose of this small canister according to OutPeak. Still, gifted horse, so let's forget I said anything ☺The included scoop is nice. It's the same one that was included with my Atmos. It holds about 9g of beans, so two scoops give you the 18g dose many people prefer. It's a basic plastic scoop, but much better quality than the horribly cheap scoops you usually get included with even mid-range espresso machines. The squarish shape helps control the beans when pouring.PRICE:The price is definitely a sticking point, especially for the size I got. I bought it for $23 on sale, which is already equivalent to almost $100 in my local currency, but I can live with that, even if I was disappointed with the size. However, normally it's priced at $46-$56 (USD), which I think is to steep for anything that hold so little coffee. Honestly, anything below the 1L OutPeak canister I think is way too overpriced. My Atmos cost $43 when I bought it, which I thought was fair for a high-quality vacuum canister that holds 250g of beans. Of course I'd pay a premium for the OutPeak's automatic functionality, but only if it could hold at least the same amount as my Atmos. This 0.5L version isn't in any way worth $47, especially when other canisters at similar prices offer MUCH better capacities and, if not better features, at least similar.FINAL THOUGHTS:In conclusion, the OutPeak Neo coffee canister is decent. It does a good job of keeping your coffee fresh for a reasonable time, and I was impressed by its performance in my tests. However, the small capacity of the 0.5L version makes it impractical for serious coffee drinkers unless you buy multiple canisters. I hope the auto-vacuum feature lasts for at least a couple of years to make it a worthwhile investment. At its current price, there may be better options out there, depending on your needs. If you're a casual coffee drinker who needs short-term storage, it's fine. For more serious use, I'd recommend doing more research before buying.
