  • Refrigeration of roasted bean

    From what I can gather the jury is still out on this topic. Has any one any good or bad points on doing this? :-/

    Re: Refrigeration of roasted bean

    At least in the Snobs world the jury is far from out on this question.

    The 3/4 word short answer: Dont do it!

    The long answer is this question has been dealt with extensively on here. Doing a search will yield further/more in-depth answers.

        i tried...
        condensation in the bag makes for damp beans, rubbishy un-even grinds, cold "sticky" oils gunking up your grinder and the flavour of the brew is flat.

        if you use the mortar and pestle method for your grinds and plunger for your brew you could get away with refrigerating the beans.

        otherwise, dont.

        snap-lock bag, push air out, store in dark cupboard... beans keep for at least a few weeks, even in the heat of a motor-home in the searing summer sun!

          I used to store my beans in the frig in an air-tight container until I became a CS member and was educated in the art of storing beans. I now use the air-lock bag which I keep in a dark cupboard after sqeezing out as much air as possible.......................

            Refrigeration .... NO

            Freezing ...  who can say ?.   I personally dont, but there are many  arguments for and against it.  

            I went to the coffee expo on the Sunshine Coast a few months ago, (too many automatics but thats another matter).  Paul Bassett was there and he said not to, while someone else from a local roastery said its fine to freeze them.

              If you could fill the bag containing the beans with TOTALLY dry air, then freeze them....... and when you thaw them leave them sealed in the dry environment until at room temperature.... they might be alright.....

              But if the air isnt totally dry (and that would be hard to ensure).... moisture will settle on the bean surface during freezing, and if the bag is opened before the contents are at room temperature - again moisture will condense on the surface.....

              I guess it begs the question - Why would you bother when you can have fresh coffee by buying / roasting just enough to last a couple of weeks?

                Could substitute Dry Nitrogen for air and it would probably work quite efficiently... Dry N2 is readily available from BOC for reasonable cost,

                  Ive done test on this 5 years ago and what i notice is the beans go bad really fast when the bag has opened. Like a banana, once in the open air from the fridge the banana goes brown really fast. Also the coffee still maintains a lot of crema. 3 week old coffee in the fridge has more crema than 3 weeks out in a bag that hasnt been nitrogen flushed. The coffee has no sweetness and in a few hours time the coffee is horrible. The coffee is flat and boring.
                  With summer coming on and getting worst every year i left the air conditioner on a nights to keep the coffee good. But the heat still killed it by 30 to 40 percent during the day. I just purchased a wine fridge and i will run it around 12-14C to store my coffee in. So hopefully thats a lot cheaper than the air conditioner!

                    Ive seen them kept at 14 degrees then packed and sealed when bought. So its probably more how hot you can run your fridge.

                      ok runnng the wine fridge at 18 C. That seems to work at its best. No direct cold air going thru it. I also put some padding at the back to reduce a direct cold surface on the coffee. I will find out how well it goes. All looking well.
