The Best Coffee Storage Canister

I remain pretty surprised about the tasting, and the differences not being particularly pronounced. Below are the links to the canisters and containers tested, and I'd love to hear people's thoughts on them.

A few quick responses to recurring questions: 1. The containers were opened regularly during the six weeks to mimic daily usage. (As I said, six weeks is a long but I hoped it would help produce more dramatic results) 2. Why no control? A good question, with a two-part, dull answer: - The coffee I used came from a 2kg bag so I could be confident it was the same roasting batch. I couldn’t reseal that batch. If I had used a retail type bag from that day I couldn’t be 100% sure it had come from exactly the same batch/blending session and it felt like introducing a variable. - The bigger idea of the testing was to look at the impact of broad technologies. Most resealable bags would work like displacement containers - so they’d work well, but not quite as well as vacuum storage. However, the differences in taste would be pretty minor. In the end my recommendations from each category as much reflect their taste impact as they do the broader experience of owning and using one. Hence I felt comfortable recommending the Airspace even though it wasn’t tested.

[@fluffyfetlocks]

It'd be interesting to see how the plastics and rubber permeate the coffee. It'd also be interesting to see how the acidity reacts with the metal containers. Surely all these materials alter flavour in some way. What might a oak, manuka or maple wood storage container do to the flavour?

What about a resealable bag with the water immersion technique? Theoretically it should be the budget version of the vacuum canisters (just like your sieve + paper towel method with blade grinders as a proper grinder replacement). Much less comfortable to use, but in theory I don't see any reason why the result should be different.

[@shannonmcbride2010]

There is another control case that I would be interested in seeing: a non-airtight container. I store mine in a '50s style tin on the countertop, but I try to use it within 10 days or so. It would be interesting to see the difference between that and a couple of the best performers in this test

[@bl6973]

I mean you definitely could use a bag sealer (those do exist) but okey

[@lightings2021]

I had the Fellow canister for several months and it did not keep the seal. After several days of the canister sitting on my shelf I could take the top off without doing anything. I noticed that after I sealed it the seal would weaken after several days. I contacted Fellow and they said that was normal and supposed to happen. So I bought the Miir canister when it was on Kickstarter. I have the same issue with trying to seal it as you did, but it works. I wish the Fellow canister could maintain its seal for longer than a few days but within a day or two it begins to lose its seal. Thanks for this review!

I’m guilty of reheating coffee too. Once my pot has been brewed (Technivorm) I immediately turn it off and remove the pot from the machine to cool quickly. I actually like the taste of the reheated stuff - deeper darkness with a hint of tar. Then again, I’m also guilty of adding cream (whipping cream) but no sugar.

[@bstr-ey6wl]

I buy coffee in a top rated brulerie / roaster who was often ranked in the best, worldwide. It does not come cheap, the coffee is not acid, nor bitter. And my tiny plastic container, is doing wonders... Just cook the inside with 14° vinegar for few days to seal the molecules. then it acts like glass.

I bought an Airscape from my favourite local roaster at their recommendation and it works pretty well. They give a discount when I bring it in to get refilled, too, so it's pretty near paid for itself at this point. Like James says, I don't know if it's significantly better than a well-sealed bag, but it's durable and dark, and since the roaster will fill it directly (and will again post-Pandemic, I hope...) means I'm not generating a lot of plastic waste.

Same scenario here, I’ve had the Airscape for apps. six years and it does a fine job of storage but then I buy beans every two weeks give or take so haven’t really noticed any issues. I also have a CoffeeVac and it shares a similar performance to the Airscape, works just fine. I’ve also experimented with true vacuum containers and with the frequent opening and resealing I just didn’t experience any advantage

[@AdamDrew]

If your roaster doesn't do a bulk refill...maybe ask them! I bet it would save them some money on packaging.

[@MrSpartanZ12]

A method that I find works to keep the freshness longer is to store the coffees in smaller containers of maybe 100-200 grams each. The reason for this in my opinion is because you reduce the number of times each container is opened. With smaller containers, the container might only be opened 3-4 times as opposed to a larger container that might be opened 10-20 times which exposes it to fresh air each time.

[@dtonpbac]

That control which is the original bag, is the best option as long as the bags have resealable ziplocs and beans are freshly roasted. Pouring the beans into canisters is the dumbest thing you can do to significantly reduce the freshness. You spent money on these to keep freshness and you pour the beans into the canister... what are people thinking..? Just leave the beans in the bag and finish it within 2-3 weeks.

[@barkingburro]

When I started using my new Airscape canisters, I was surprised at how much longer my coffee retained good flavor. I especially noted how roasts I was familiar with had an extended “break-in” period-over 6 days-before they started peaking in flavor and no longer tasted grassy. Also, I highly recommend buying 2 small canisters instead of one large canister. I keep approx. 1/2 lb. in both, and avoid opening the second one until the first one is empty.

[@amieinnovascotia3237]

barkingburro: good idea. Personally a pound of beans doesn’t last long enough here. I do use the Airscape (comes in pretty colours too). Although I have most of a bag of flavoured beans (I’m not a fan but a visiting niece likes hazelnut) and what is left I vacuum sealed in 50 gram portions in a food saver and tossed into the freezer for next time.

[@WisdomFolly]

Although I learn a lot from you, I am not nearly so fussy about coffee as you are. Finally, a test that has a direct impact on my coffee life! The reason vacuum-sealing did not result in significant outgassing is because after the initial purge of air those beans were never exposed to air again until shortly before use. Had you opened the container daily and re-established vacuum (as I would use such a container rather than inexpensive vacuum bags) you might have produced a different result. Always interesting, informative, entertaining -- I enjoy your channel and I wish we lived at least in the same hemisphere so we could be friends IRL.

[@YunisRajab]

Which is the downfall of vacuum jars. Don't see the point of them

[@jadoei13]

@@YunisRajab Maybe they're useful if you get 1kg of beans and want to store half of them in one of these for a while. Getting beans at a local brick store is pretty hard around here, and ordering half a kg makes them rather expensive as it adds 4-7 euros to an order (thus adding 8-14 euros to the kg price). Luckily most just come in half kg bags and there is seemingly little need for these.

[@user-fk8rb8ue5h]

I'll be honest I've tried all sorts of coffee beans and ready ground. With so many variables such as the water flavour etc, I find little differnce. I grind 200 grammes at a time and put it in a container. By the time I get to the bottom there is sod all difference and yes I have tested it against freshly ground. Haven't I just. I really do believe that there is so much hot air and snobbery around coffee it's all down to personal taste.

[@mignav464]

After years of using the Coffeevac, I can tell you: I have observed cracks in the bottom of the containers, eventually making them unusable. Remember, they're made of plastic, so they will have an "exipry date". I have recently moved to the Airscape, for three reasons. 1. they will never have cracks, since they're stainless steel. 2. you can buy REPLACEMENT lids, both for the inner and the outer lid! 3. there's less air sealed in than with the Coffeevac.

James, great content as always! I actually bought the Fellow Atmos Canister after a bit of research, your review definitely influenced my decision. I need to inform you that there seems to be an issue with the lid. The pumping mechanism is failing on my Atmos, it stopped functioning after only two weeks of use. I've contacted the company and they replied that they recently identified an issue with the sealing component of the Atmos lids. In light of this discovery, they have stopped shipping the Atmos canisters until they can guarantee quality. The good thing is that the Fellow company is aware of the issue and is transparent about it. They are also keen to send a new lid, once they fix the issue, but there is no ETA for that. Finally, they allow you to request a full refund.

[@Shadowguy456234]

Because, as a household of one, the coffee consumption here is at such a slow rate that my coffee is going to be sitting around getting stale simply because I can't drink it all before it does, so getting better coffee storage makes sense, if I don't have to spend an arm and a leg on it.

Hey James, I know this is an old video but wanted to give you another experiment you could do with these. In the food packaging industry, part of the calculation for shelf life of dry goods includes weighing the food at certain intervals to see how much moisture it has taken up. If you were to design an experiment around weighing the beans before and after 6 weeks in each container, you should be able to see which system has the most integrity by seeing which one gained the least weight.

[@gray_gogy]

Not sure that a test would be necessary for that, its obvious that the vacuum sealed containers would perform the best because there is the least air in those containers. At the end, the most important thing is the taste and he already tested that.

[@iteese]

@@gray_gogy That also depends on how leaky the vacuum canisters are. A poor vacuum seal means moisture will get in over time.

[@oysteinsoreide4323]

That experiment is highly dependent on the humidity at the place of storage. It will be very difficult to test.

[@cyberlord8]

@@iteese For long term storage of dried goods, I agree. So for green coffee beans a proper vacuum seal would be important. For roasted coffee not so much.

If you do use mason jars, you could vacuum seal in appropriate measurements for your preferred brew using the food saver jar sealer. No wasted plastic and you reuse the lids too so no waste. A can of spray paint will take care of sunlight coming through the glass. Now it won’t last forever. For me with one pound of coffee that would mean 7 jars sealed (you could easily keep two days worth without doing anything special). Only if you’ve got loads of time to fiddle away. I don’t do any of that though. An Aerscape canister or a plain steel tin with a wooden lid seems fine in the time it takes me to use it up - 9 mornings, if I don’t have company; which I do often.

Agreed, need a control open air and possibly coffee stored in the factory bag

[@xiola]

He does reference factory bags at least twice in the video, and says he'd just as soon use them over a canister. I expect the ziplock bags with a one-way air hole should, in theory, be sliiightly better than displacement (because the sides aren't solid so you can get more air out), and the roll-top bags would basically be sliiightly worse than displacement (because it's harder to get all the air out)? I do put mine in a second ziplock bag just in case tho, especially if it's roll top, since the plastic lining in those paper bags trends to be pretty thin and I don't trust the seal.

[@ohreallybigdeal]

When I open a new bag of coffee, I divide the coffees and put them into 4 oz mason jars, which are then placed inside a cabinet. That way, I minimize air contact and "agitation" without breaking the bank. The jars are also easily stackable/rearrangeable for tight spaces.

[@jcvan]

50g of beans always "just fits", so far in those jars. I found some narrow kitchen trays that keep my vertical stacks of four 4 oz jars in the door's bottom shelf. So up to 200g each of caf, decaf, and espresso.

[@pieman7]

Extremely informative video! I'm glad someone went through the time and effort to evaluate these storage technologies. Since the difference in results are relatively small, the more significant factors in storing are IMO: 1) opacity so light doesn't accelerate the reaction to any remaining air, 2) fewer parts probably means more durability, 3) pick one that's easier to use (large hands and small openings are a pain). Thank you so much for this video!

[@BigPappy1231]

Hey James, great review! Next time around for a test like this, would you mind adding a control? I feel like it would have been a nice addition if you had tasted a regular bag of coffee beans that you had opened at the beginning of the 6 weeks. Keep up the good work, I love your videos!

Totally agree with this. I would have really liked to have seen a regular zip bag of the same coffee tested along with the others. Otherwise great video as always.

[@chrisatlee]

I was curious about this as well! I was also was wondering about how the ratio of air to coffee impacted the results. A smaller container would have less air in it, and so maybe wouldn't stale as quickly?

[@DonSWG]

James, I really appreciated this test! I have a Fellow Atmos and I enjoy it. It isn’t a night and day difference, but it does seem to extend the “golden period” of the coffee by another week. Secondly, you absolutely can take the metal disc out of the top! You simply remove the rubber gasket and remove the metal piece and cloth thingy below it.

Although it’s the only solution I’ve used, the airscape does do a fairly good job of increasing the “enjoyable” shelf life of coffee.

[@TamarLitvot]

I also have an airscape and for at least 4 or so years. Coffee is good (we keep the beans for about a week to 10 days). Durable, washable and its biggest advantage-simplicity. My technology-challenged husband has no trouble with it (except occasionally not having beans and air extractor level).

[@slipshodaverage844]

I've had an Airscape canister for almost two years now. I've been very happy with it. I've started ordering 2lbs at a time from a nearby roaster. I vac seal 1lb in the freezer, and keep the other 1lb in my Airscape. I haven't noticed any big changes between the last cup from the canister, and the first cup from the thawed freezer bag.

[@amieinnovascotia3237]

I have been doing pretty much the same as you have, SlipshodAverage. I have been vac sealing the beans destined for the freezer right in the bag they come in. Saw how the FoodSavers can be “tricked” into working with regular ziplock bags too but I don’t bother doing that with the coffee beans as it creates so much plastic waste. However, I do seal in glass Mason jars. I find the 8 ounce jelly jars hold the right amount (50 grams in my coffee maker) for each pot. My pantry is like a very cold fridge much of the year. Oh: using Mason jars, you can reuse the lids too.

Fascinating how little things like a coffee ritual can affect a life! Thank you Mr. Hoffmann. :)

[@JCleggy]

I appreciate the comment at the end about keeping the coffee in a resealable bag. My method is to leave the coffee in whatever bag it comes in, squeeze out as much air as possible, put that bag in a freezer gallon bag and again squeeze out as much air as possible. I’m convinced that oxidation is more a function of free air exchange and less about total air-tightness

I absolutely love your videos Mr. Hoffmann! I have been taking my careful steps into the wonderful world of coffee, and have been enjoying your videos thus far! I started off with the standard pre-ground coffee from Tim Hortons, brewed in the K-Cup Keurig machine I have from my college days. Now I have a little electric coffee grinder and a De'Longhi Dedica I got off kijiji a while back and have been having a lot of fun learning how to properly make espresso, and it is absolutely delicious! Haven't splurged yet and gotten any specialty beans or upgrade my espresso machine as of yet, but I'm excited to continue moving into the wonderful world of coffee. Thank you for sharing your knowledge on coffee science! It is very much enjoyable to see!

[@SimpleKindOfLiving]

I own a Coffe Vac. The valve that you mentioned is also an oneway check valve allowing the CO2 to escape. That might be why you liked that one better than the others in that category.

[@thePronto]

If the CO2 is able to 'escape' into the ambient air pressure, then not only is the vacuum gone, but the pressure of CO2 is higher than the local air pressure. Furthermore, the vacuum is not being restored. On the upside, CO2 isn't degrading your coffee...other than it is an indication of getting stale...

[@cibazolnorbert4889]

@@thePronto CoffeeVac is not "vacuum" system. But it is not very good name - making confusion.

[@nternalPractice]

One thing James didn’t take into account is the amount of coffee being stored. I have the airscape and, what I like about it is the fact that the volume inside the container is essentially variable. It works just as well with a small amount of coffee as with the larger amount of coffee because you can push the lid down until it contacts the coffee.

[@DNGR369]

Good to see you still going during this time. Hope you are well senor James. Big love from Tasmania.

Hi James! This is a small note but the date dial on the Friis container isn't actually for the coffee (but it could be!), its for keeping track of when you last put a new C02 filter in the lid, which in theory should be replaced each month, hence the 31 days

As a comparison I ran an experiment a while ago with vacuum seal bags. Right after roasting I sealed 1oz of coffee in each of two small bags. One bag I left at room temperature. The second bag was immediately placed in the deep freezer. Results: The bag at room temperature was puffed out after just one day from off gassing and was ready to pop after a few days. The second bag in the freezer maintained a perfect vacuum for weeks. I then took it out of the freezer and it did exactly what the first bag did. Puffed up after one day and ready to pop after a few days. So the freezer totally prevented off gassing. So it seems that by putting freshly roasted coffee in vacuum bags and freezing you can have almost indefinite perfect storage with identical taste to the freshly roasted that wasn't frozen. Note: I only do pour overs so I don't know what effect it would have on crema or other things in espresso.

[@jennijawsz]

Thank you for such an informative video! I actually bought both the Miir container and the Fellow, and found that I gravitated towards the Miir out of convenience. To twist the Fellow tight every time I wanted to make coffee ended up being very cumbersome to me. I definitely appreciate the comments from others about storing batches of smaller coffee to reduce the amount of opening times which I never thought of. Thanks for all this great content!

I’ve been thinking about getting the atmos, but I saw some reviews about it losing a vacuum after a few days. Thanks for the explanation about that being caused by the gasses releasing from the beans! I hadn’t thought about that, it makes a lot of sense!

[@ordinarycable]

Same reason I came here! Did you ever try it out?

[@SS-hc6sp]

It would have been cool to see him test the theory - like is it really off-gassing or a shoddy seal? I suppose if you used an esp32 with WiFi and CO2 sensor and solid state barometer one could determine how much off-gassing is happening and pressure change is happening to determine if it’s a bad seal or just gas released from beans.

[@hani1615]

This was well thought out bar the missing control. If there is no discernible difference between storage in a bag or in a container then these products are less important.

James, this was really interesting. I have three cylindrical 'Vacuvin' vacuum jars that I bought, many years ago, from a Whittards high street store (I'd guess around 30 years ago!). I've used them for all manner of things, but primarily storing coffee, and found them to be very effective at extending storage life. The ones I have look a little easier to use than the vacuum jar you have, to release the pressure on the rubber valve, you just squeeze the sides of the rubber bung. It's also easy to judge when you hit the maximum evacuation, as you can tell from the feel of the pump. Another interesting element (given your video about freezing coffee) is if you have a large bag in the freezer, you can quickly pour out some into the vac jar, evacuate it and there's no condensation or moisture build up on the coffee, as you let it defrost. They were discontinued years ago, but it looks like the unit you tested is a spin-off: www.shopvacuvin.com/Tomorrows-Kitchen-Medium-Vacuum-Storage-Container-p/28733606.htm Mine look like this: lh3.googleusercontent.com/pw/ACtC-3fWJp_-9viaUF6pzkrDHvSDQwlFKhPGUBd0UenB1kzFfmkj_xAUsSLs-cJfekenyEu6PYO2PU8OhvUUgfpk21eJmF5_9hcOSMigA5npUap_ky8PDTDlENibBlVxQLZwt1eKBlc6DnVNuroZlXbEGdBWYw=w958-h539-no?authuser=0 P.s. they're great for rapid marinading of food too!

[@jamzam7976]

I’ve tried several canisters, but was never convinced they worked to extend freshness or flavor. I eventually just started using rubber straps to seal the coffee in the original foil-lined bags I purchased them in. When I pull out the beans for the day, I fold the bag over to remove as much air as possible, and then place a large rubber strap around the bag to keep it flat/sealed.

[@BasicPsychology101]

And moving the built in value further down the bag so when it’s half full one can roll it down further to displace more air? Probably a reason this would not work... just a random thought.

So proud to be one of your patreons and watching your videos!

[@bjorksven]

I use a decently wide and simple container of the "just airtight" type, and I keep the coffee in the bag that I get it in, inside the container. I cut the top off the bag and then keep it closed using a plastic clip. That allows for minimizing the volume of air above the coffee, just like for the "second" category of container, but in a simple and cheap container. Double-sealed system (together with the container lid) and non-transparent because of the bag, for cheaper than a complicated solution. I use very dark roasts, and I do notice a definite difference in smell when I open a new bag of beans compared to one that has been open for a while, but I haven't made any back-to-back tests like this. There have been other things that have impacted the coffee flavor more for me, and I'm glad to say that this channel has given me a lot of ideas and opened my mind to how to start going about making my coffee taste better!

[@ernestthornhill8222]

Another alternative to consider is using gas displacement. I've tried using many of the canisters you've reviewed here, and while I had best results with vacuum canisters, they're just too fiddly to use in the morning. My alternative is to use an opaque one liter airtight canister, that I fill half way with coffee, roughly ~220 grams, which is enough for 5-10 days of espressos for me. I then fill the container with an ounce of carbon dioxide from a small tank, the sort sold to use with home soda machines, which holds ~14 ounces of gas. This is more than enough to repeatedly fill the one liter volume of the air tight canister. It's not a precision operation; since CO2 is heavier than air, as long as there's enough gas to cover the coffee, a gas barrier forms and oxidization is significantly reduced, and one ounce of CO2 is enough to displace a liter of air several times over. A little air will get mixed in every time the lid is opened or coffee is scooped out from the top, but it's not significant when coffee only lives in the container for around a week. When I run out of coffee, I transfer a week's worth from the freezer, and shoot another ounce of gas into the canister. I've also tried using argon gas displacement, which works as well as CO2, but there wasn't any discernible difference in taste, and recharging a small CO2 tank costs significantly less than having a tank charged with argon.

[@thegrynne]

Something that might be worth considering: how much water/humidity is lost from the beans stored in air-tight container vs vacuum-sealed. Although the beans are all supposed to be equal in weight for each test in the espresso section, perhaps the density of the beans are different due to how they are stored--and hence they behave different when ground wrt channelling?

[@brindlebeard]

I use the Fellow and it’s been great. If you use the coffee daily it never looses pressure in my experience. I stick with one bag of coffee until used and I get a better cup at the end of the bag with the Fellow vs when I used just an airtight container.

Such a great vlog! Thank you for making this particular video.

[@barkingburro]

James, I would like to see you do a test to see if the vacuum storage does harm during the first few days by prematurely removing the CO2 and allowing oxygen to contact more surface area after grinding. Since fresh roasted coffee outgasses CO2, it would seem that repeatedly vacuuming out the CO2 would encourage oxidation of grinds. You would need to repeatedly open and seal the container, say, two or three times a day for two days. Then on the third day, let the just-ground coffee sit for one, two, and five minutes (three different trials). The control would be the same batch of coffee kept in its bag or an Airscape container that is unopened for two days. We want to see if there is some point at which enough CO2 remains in the control so as to produce good flavor after outgassing, compared to the vacuum treated coffee that has had more of its CO2 removed so that the grinds quickly stale after 1, 2, or 5 minutes.

[@forrestbenton2286]

I'd argue a resealable coffee bag is actually closer to the displacement method because you can press out the atmosphere before sealing. It would be interesting to see how the same coffee in a resealable bag faired here. Curious also for the use cases. Many viewers of yours are not likely to keep 12oz of coffee around for 6 weeks. 3 weeks with 1 week in original packaging may have approximated closer.
