About this deal

My point is, are we regularly removing non-reactive gas and replacing it with o2? And is that happening to a degree that nullifies or even is larger than the positive effect of a lower pressure environment? In a side-by-side comparison of airtight, displacement, and vacuum storage containers, the differences are quite stark. James Hoffmann, YouTube coffee influencer extraordinaire, put about a dozen containers to the test—tasting coffees stored in various airtight, displacement, and vacuum canisters—followed by an espresso-pulling test to better highlight any differences. In his video, Hoffmann admits there wasn’t a huge difference between the coffees during his tasting, but that vacuum canisters did, in fact, perform better.

Oxo manufactures a variety of items to help households run smoothly, including its line of Pop containers. The 1.6-liter option is specifically designed for coffee, and it's one of the best values compared to other coffee canisters out there. Where this does shine is in the aesthetics. This is one of the most beautiful canisters to show off your beans to whoever will take a gander. Clean, simple design that works for minimalists and maximalists setups. Once you've followed these steps, it should hold a seal between four and five days. Please remember that Atmos is designed to hold whole beans and not ground coffee. You can repeat the above process as you see fit to maintain your Atmos. So please consider what your putting in it and how long you want it to stay sealed before your buy this item.Okay, not a bad thing, right? The beans are good to brew with now! You keep storing the beans, setting a vacuum, etc. Each time more gas gets pulled out of the beans. But here's the thing... C02 is (remember, regular non smart person here) non-reactive with the beans. So we're pulling out a high concentration on inert gas from the beans each time it's put in a vacuum. Then, when we open the beans container... We introduce air, which, if I remember correctly, is 21% o2, who is coffees worst enemy. Of course, we then create a vacuum again... But now with a mixture of gasses that constantly introduce more o2. In fact, the beans, if one can imagine then as a sponge, are super dry in the vacuum, and once regular atmosphere hits them, the pressure forces the regular o2 laden air into the beans.

Now let's look at the beans. Many of us know that fresh roasted beans have a lot of trapped c02 as a result of the roasting process. This is why it's best to brew a week after roasting. Normally, in normal pressure, this c02 would diffuse out of the beans over time. Eventually, oxidation begins to dull the coffee and remove the nice flavors, making it stale. Atmos is available in three sizes. The .4 L Atmos holds up to 6 oz of coffee beans, the .7 L canister holds up to 10 oz of coffee beans, and the 1.2 L canister holds up to 16 oz of coffee beans. But remember, some varieties of coffee beans are bigger than others (looking at you, Pacamara). Can I put Atmos in the freezer? This canister is available in three sizes and multiple colors. The medium canister, which we tested, comfortably holds 1 pound of ground or whole bean coffee. We filled the canister with water and shook it upside down over the sink to test the integrity of the airtight seal. Not a single drop of water escaped, showing how well your coffee beans will be protected inside. The item should not be put in the dishwasher, but we washed inside the canister with a sponge without issue. This is an updated version of a previous Oxo coffee canister. The two are similar in size, price, and design, but the newer model comes with a couple of upgrades, especially regarding its ease of cleaning. It is now dishwasher-safe (aside from the lid) after previously being hand-wash only. Airtight Container Storage – Feel assured the freshness and quality of your coffee will last for much longer.Displacement containers are another popular option, especially in the coffee and tea market. These devices rely on shrinking the area in the device, usually with a lid that you push into the container. As you press the lid, air rushes out, removing “empty space” between the lid and it’s contents. Despite the fact that this type of product removes air, in practice, there isn’t much difference between this type of storage and folding up your coffee bag, smooshing the air out, and tying a rubber band around it. Sure, it limits oxygen exposure, but oxygen is still present, albeit much less than in airtight containers. Vacuum Le Creuset is well known for its colorful cast-iron cookware, and these stoneware canisters capture the brand's signature style. They are available in several eye-catching colors, from a cherry red to an elegant white, so every customer should be able to find an option that matches their kitchen décor. The canisters also have a wooden lid for a nice accent. While glass isn't the best material for a canister, as exposure to sunlight causes coffee to go stale faster, the Bodum Yohki storage jar tested well enough that it deserves inclusion on this list. (It even outperformed several stainless canisters that we tested.) Just try to keep it out of direct sunlight if possible.
