1LB Patented Airtight Multi-use Vacuum Works as Smell Proof Ground Coffee Bean Containers. Black Cap and Body, 1.85-Liter/1.6-Quart

This keeps my coffee so fresh. When I don’t use my keurig this keeps my coffee grounds so fresh and ready to perk. What a treat.

Great value. Easy to use. Works as advertised. There's no reason not to get this. Keep your beans fresh!

I was surprised to find out both how fast coffee loses its flavor, and how good fresh can really taste. I got into roasting my own green beans (available HERE on Amazon: Costa Rica Dota Estate, Green Unroasted Coffee Beans, 1lb) with one of the poppers still on Amazon that will do so (they are HERE: Toastess TCP-713 Hot-Air Popcorn Popper and HERE: Toastmaster Hot Air Popcorn Popper TPC2), then brewing them in the inexpensive little Bialetti Italian moka pot (available HERE: Bialetti 6800 Moka Express 6-Cup Stovetop Espresso Maker) for AMAZINGLY fresh coffee I'd never experienced being American!All the barista sites I've surfed (source aapbr dot org) told me that: green coffee beans, when cool and dark, last a year or two in storage, and some (Arabica) even get better with age. Once you roast them, after three or so days of CO2 release, they start to lose flavor within TWO WEEKS! Once you grind the beans, the grounds start to lose flavor in FOUR DAYS. This is all trumped by the correct storage techniques. Here are the ones I've tried on Amazon that work GREAT, and don't cost a fortune like the vacu seal machines that can be over $200 US!Green beans: I use the "pseudo vacuum" of the COFFEEVAC (see it here: Tightvac Coffeevac 1 Pound Vacuum Sealed Storage Container, Solid Black Body/Cap) which isn't a vacuum at all, but works fine for green. Does NOT work for new roasted as it doesn't have a co2 release valve.Freshly roasted beans step one: For the first 3 to 4 days you need a container with a CO2 release system. One (the Friis, see it HERE: Friis 16-Ounce Coffee Vault, Stainless Steel), is more expensive and has replaceable filters. The other (The bean safe, see it HERE: BeanSafe "The Coffee Storage Solution", Polypropylene -MOCHA) is cheap, and only has a small valve, but doesn't require replacement filters.Freshly roasted beans step two: Best is to use right away after the three day roast period. Roast just enough for your next few day's needs. The normal popcorn popper will take 81 grams for roasting green beans (about ½ cup or about 5 tablespoons green). These yield (bigger) roasted beans of about 9 tablespoons. Since a tablespoon of ground is roughly the same as a tablespoon of roasted beans, and the moka takes 3 tablespoons for 6 cups of espresso/moka each pot, that gives you roughly three days of roasted beans. I keep the roasted (since they will be used in a few days) in the next "step up" of vacuum: a semi-true vacuum with the airscape sealer (see it here: Planetary Design Airscape 64oz Chrome). This gets close to a "real" vacuum, and just enough to let a little extra CO2 escape over those 3 days.FINALLY, for fresh grounds, the most vulnerable, you'll need a true vacuum to extend the life. I use the handheld freshsaver from foodsaver (10% of the cost of the foodsaver system, see it here: FoodSaver FSFRSH0060-035 FreshSaver Handheld Vacuum Sealer with Starter Kit, Red) with the little "Tupperware" reusable foodsaver tubs. In the cool/ dark (don't refrigerate) this vacuum will keep fresh grounds fresh for over a week, close to the taste when just roasted.For background, I'm not a coffee snob, but as a throat cancer survivor I have barely any taste buds left and coffee is one of the few great tastes that still work. Also, the above is FAR less expensive than either buying drip or certainly Starbucks. Amazon has green beans of very high quality (see link in first paragraph). These can be (eg. Sumatran Arabica) over $40+ a pound roasted, not very fresh when you get them, and you can get them for under $10 at times on Amazon GREEN, REAL savings. Enjoy!

I just got the product today. I ordered it thinking this was vacuum sealed container that removes all the air. It does not. The lid creates a tight seal that you press a button to release the air under the lid when you push the lid down. This creates a vacuum, which is why it's considered a vacuum sealed container. And it is an airtight container. But it is not a container that removes all the air inside the container with a vacuum. If it does extend the life of the coffee grounds by 3x. Then it would probably still be fine for my needs. I'm only giving it first stars because I don't know whether this is going to be good or not. I just wanted to make this comment in case someone who is looking for the ame thing I was looking for doesn't make the same mistake I did.

Works great. Easy to use.I buy a 28 oz bag of espresso and vacuum seal all but a pound. Add rest goes in this canister. Stays fresh til gone then i add rest of sealed coffee and all together it stays fresh till the end of month. Dark roast espresso is so good.

Just keeps my coffee really fresh. It took me a minute to figure out how to open and close it but it’s really easy once you push the button in.

Work easily and effectively. Keeps contents very fresh. Use mine for coffee bean storage. a 12 ounce bag fits perfectly.

Used for over a year and it keeps ground coffee fresh
