  1. No, an airtight container is the best storage for coffee. The cold temperatures and lack of controlled humidity tends to affect the flavor of the coffee (not to mention flavors from other food).
    Good airtight containers are easy to come by (most kitchen stores should have them in glass or stainless steel).
    And if you’re looking for the rolls royce of coffee containers, try this one:

    which we use at home and are happy with.

  2. I keep my coffee in the freezer in an airtight container and find that it holds the flavor better for a longer period of time than the airtight container at room temp. As an added benefit, the cold keeps the oils in the beans in a more solid form and my grinder stays cleaner for longer.

  3. There has been several double blind experiments on espresso beans frozen shortly after roasting conducted over at: Home-Barista.com notably Coffee: To Freeze or Not to Freeze and Freezing Espresso Coffee, Part Two . General consensus is that freezing did preserve the freshness of freshly roasted coffee for up to 6 months without significant degradation in bean quality, provided that the frozen beans were in air tight sealed container (mason jars were used in the experiments), the beans were allowed adequate time to thaw before use, and the beans were kept uniformly cold (no huge temperature swings, as might happen if the beans were in the door of a residential combination freezer/refrigerator (notably, the experiments on Home Barista used a deep freeze chest).

  4. Coffee is not a potentially haxardous food as it is dry and therefore will not allow bacterial growth. So it is highly unlikely to cause food poisoning and therefore does not need to be kept cold. Mould can grow and you have probably seen mouldy coffee before. It needs to be thrown out an not used. Keeping coffee cool will slow mould growth. Many people like to keep their coffee cold or even in the freezer and this slows down chemical reactions in the ground beans and extends the usable life or the product and maintains the flavour. Whether in the fridge, freezer or cupboard the most important thing is to keep the pack well sealed to stop oxygen and moisture getting in.

  5. The roasting process causes chemical reactions that leave CO2 inside the beans. The outgassing of the CO2 over several days and weeks also brings some of the high vapor pressure components (responsible for aroma) with it. If you see the one-way valves on coffee bags, these are for letting the CO2 out without letting O2 back inside. Freezing will delay the outgassing effect and any other chemical reactions. However, the other answers about the beans trapping other freezer odors are correct. If you freeze beans without keeping them in an airtight container, they will get soggy, etc. And once you pull them out of the freezer, keep them out, because atmospheric water will adsorb onto the cold beans very quickly. Freeze your beans if you can’t use them in a week or two. And thaw them without opening the container.

  7. In my experience, coffee in the freezer means that the coffee picks up odors from the fridge since we have a single-compressor fridge. Also, the residual moisture in unground beans tends to freeze out and also seems to affect the flavor.
    The best thing you can do, really, is buy coffee often and use it up regularly. That, or buy green beans and learn to roast your own, because green beans keep for a much longer time.
    In any case, I tend to agree with everything in this article:
