  1. I use a airscape container, it is plunger style vacuum sealed container made specifically for storing whole beans. They are quite affordable and good at maintaining the freshness, the coffee shop where I bought it offered a free fill up with beans of my choice, which I thought was a pretty good deal.

  2. Are the beans roasted or still green?
    If they have been roasted, oxygen is their enemy. You want to get them into a plastic (polyester actually) bag that is foil lined and has an integrated one way valve to allow you to get all of the air away from the beans. Mak…

  3. These things cause degradation in coffee:
    So, eliminate exposure to those.
    What most people do: seal the bag with a bag clip and keep it in a cool, dry place away from light. Drink before two to three weeks.

  4. It’s just me, so I buy a twelve-ounce bag, which gives me roughly twenty-four servings (two cups). This gives me roughly around 3 weeks of coffee.
    Beans usually last about two weeks before the taste begins to go south (but still reasonably good to drink), so I store four ounces of it in the freezer using a simple sandwich bag after opening the coffee bag. That gives me another week of fresh-tasting coffee.
    I take it out of the freezer and put it in the cupboard.
    I don’t worry about light, because the cupboard is dark when the door is closed.

  5. Close the bag as tightly as possible. If this isn’t practical (bags are often too fragile for this to be a good idea), a separate freezer bag is my preference.
    There’s a lot of information that suggests putting the bag in the freezer is bad, but in my experience if you use a heavy duty bag that seals completely, this provides the best solution. Using a hard-bodied container that seals well is also effective, but large volumes of empty space (as when there’s not much coffee in the container) result in some amount of freezer burn.
    I’ve had success with this method despite sometimes storing beans for months, and I’ve rarely had an unhappy “customer”.

  6. Lots of good answers here. The only thing I would add is to never save your “good” coffee no matter how you store it. Even in perfect storage conditions, coffee goes bad. Use it up while it’s still fresh is always best.

  7. In a sealed container. As soon as a bag of coffee beans are opened they have a 31 day shelf life.
    If the beans are already ground then they only have a 7 day shelf life.

  8. I agree with Guy McCardle Jr. I roast my own beans, 1 lb at a time and store them in foil lined bags with the one way valve to let them degas. I taste a difference day to day in the coffee but that is due to normal aging and I never have anything remotely stale or off.

  9. I bought a glass container with a plastic valve lid that I use. I just lift the valve and suck the air out after every use. It works great for me!

  10. If it’s roasted beans, I usually use a mason jar or thick freezer bag. Fill the container to the brim to allow the smallest amount of air, & keep in a cabinet or pantry away from light & excesses in temperature. I try to use the smallest size possible so that when I do open it, it will be for use that week only. That way you’re not opening & closing the container alot.


  11. Never store them in the freezer. They will condense when they hit the warm air and become moist….then potentially moldy. It’s best stored in a cool place in an opaque air tight container.

  12. After opening a small bag (say, 1 pound) of coffee beans, they should be stored in an air tight container or a jar with a screw cap top. I keep a few used pasta sauce jars handy after washing them thoroughly.
    If you wish to store the beans for a long period, or have bought large quantities of roasted coffee beans, I recommend freezing them in air tight containers. Retrieve only that amount of coffee beans from the freezer which you plan to consume in a week or two.

  13. Coffee beans lose their freshness when exposed to air, heat, moisture and light.
    The best way to store them is in an air-tight container, in a cool, dry, dark place. Ideally you should also use your coffee beans within 2 weeks before they totally lose freshness. Also, DO NOT EVER STORE THEM IN THE FRIDGE. Trust me, your coffee is gonna taste real bad if you do.

  14. Most coffee bags have a small one way valve that allows the release of cO2 from the coffee and helps it breathe out, but not in. These coffee bags are quite effective when sealed at the top. The better you seal them, the longer your coffee will last. It is best to let the cO2 escape, so putting beans in an airtight container may not be the best.
    Most bags last me a week or less, so simply rolling the top down and putting a clip on it seems to work just fine.

  15. General rules:
    The storage room must be a dry and preferably dark environment.
    Keep away from smokes, dust, and bad smell.
    Roasted beans deteriorate fast, it is generally acceptable that roasted beans can only last 30–45 days after roasting date.
    Do not keep it in the fridge.
    The containers must be tightly sealed.
    Avoid plastic containers.
    If you bought it after freshly roasted, ask the roaster how many days you should aired it for degassing. In my experience it could take 3 -10 days.
    Options for storage:
    If the package is a foil bag with one way air valve, it is the best for storage.
    Mason jars or any sealable glass containers.
    Metal containers, use paper bags inside.
    Personally, I always keep it in its package, unless the package is just a regular plastic bag, I will use my jars.

  16. Sealed
    Coffee releases gas after its roasted
    That gas or ‘aroma’ carries with it, flavour
    You release more of that ‘aroma’ when you grind your beans
    The gas is what people describe as ‘freshness’. Losing that gas leaves little aroma, therefore less flavour.
    The bean will continue to release it over time, and there’s no way to stop this process. Trapping the gas helps contain the aroma but it cannot be put back into the bean. You want to release it all at the same time – therefore containing it together.
    Gas build up though and expands its housing, so bags generally have valves to stop them exploding.
    A properly sealable vessel made of something sturdier can help. It’s just better to roast regularly, and drink the coffee in the desired window rather than attempt to save it forever in an ingenious way.

  17. I usually order 1 kgs of classic italian blends. They’re usually way more forgiving than any third-wave (new-wave, speciality, light roasted etc.) coffee beans after roasting.
    As soon as I open a new bag, I split it into three portions and fill glass containers as full as possible. My favourite is from IKEA: KORKEN Üvegedény+tető – IKEA
    I put all the full containers in a room temperature storage place, and use only one for daily basis.
    Whith this method, I can’t notice any significant change in caffee aroma between the (almost a month) old and the freshly opened bag. By the way, these blends are really forgiving.
    When storing roasted coffee beans, be careful to avoid:
    — contact with air,
    — contact with moisture (or high air humidity),
    — repetitive fluctuation of temperature, as well as too high temperature (above 30 degrees Celsius).
    The one-way walve solution Guy D. McCardle mentioned is a good solution for smaller portions and/or new wave coffee beans.
