    Storing Green Beans

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I am new at roasting but have already got a collection of beans sitting in the spareroom. Does anyone have any suggestions on the appropriate storage of green beans?

    Re: Storing Green Beans

    For best results should not be stored in sealed containers or in humid environments, or could ferment and go off.

    Therefore suggest no air tight containers, no heat, no direct sunlight, no fridges and therefore, a paper bag in a cupboard would do it for me.

    Regardez,

    Plain cotton bags in the bottom of our linen closet (amongst some of our wine collection) does it for me. You could simply use pillow slips.

    My wife found the perfect excuse to buy a new sheet set. She converted pillow slips into doubled thickness bags with a draw string. Clever girl. I have a couple of new bags and she got a new sheet set. I think I got jipped there, but Im not sure, anyway, were both happy. ;D

    The big brown bags they shove your beer/wine etc in at the local pub/bottle shop work pretty well and hold quite a fair volume too. Just try wrestling one off the local Dero and chuck the bottle away. ;D

    I just put mine in non-sealing jars in a fairly dark closet all that being said. No ill-effects thus far.

    Re: Storing Green Beans

    We have close to 130+kgs that are stored here and luckily we are not near the Sea and so the Humidity is not a great concern for us, But we store our beans in the Calico bags that you get from Aldis and then in a cupboard we have in our walk-in pantry. I think the secret is that they be stored in a cool dry environment, with adequate air flow.

    I heard that if the conditions are right green beans can be kept this way for around three years or more.

    Another point is one must conceder is to keep them free from pests etc..... never seen a mouse high on caffeine yet, but even insects could cause a problem as well.

    Hope this helps

    Re: Storing Green Beans

    So an ice-cream container is not a good idea?

    Re: Storing Green Beans

    JD,
    It depends. I use plastic containers with a lid (not airtight). They are dry and out of direct sunlight. They have done the job for me without any dramas so far. I think the ice cream container would be OK for short-term storage (say 6 months) as long as they were cool and dry, but as many above have said, for long term, perhaps cotton, paper or calico bags.

    I have found the beans are ok in plastic so long as they are not left in the sun they tend to sweat.

    Thats a thought there Rich, so there lies the common thought, "Keep them Cool"

    Re: Storing Green Beans

    Hey Guys,
    I just had an idea...
    I am about to get my first green beans tomorrow, and living in sydney means it gets quite humid.

    anyone considered putting some silica beads in a bag in with your green beans? You can get them in shoe boxes or in the new style cat litter..... (unused of course )

    what do you think?

    Hi clarexican,

    Silica Gel is a very anhydrous substance and hygroscopic as well but not necessarily at the same time. Once it has absorbed moisture to the point of saturation, it can then be rejuvinated by spreading out in a thin layer on a biscuit tray and placed in the oven set at about 150 C for an hour or so, depending on how much gel there is.

    As for using it to keep ones beans dry, Im not too sure really. From what Ive read, beans should be kept such that their intrinsic moisture content by weight, is at or about 12%. Really anhydrous silica gel (freshly rejuvinated or straight from an air-tight pack) may leach this moisture content down to a level that is detrimental to the bean. Most proponents of correct bean storage seem to recommend that beans are stored in a cool, dark place in natural fibre bags such as calico that will allow the beans to "breathe".

    No doubt you will receive as many differing recommendations on storage as there will be replies to your post. A good place to start though, is to do a search via Google on the alt.coffee newsgroup on "green bean storage" and you will see what I mean. Anyway, for what its worth I wouldnt use silica gel within a sealed container full of beans, it might just do more harm than good. Better to stick with what has been used down through the ages I reckon: burlap, jute or cotton sacking. Hope this helps,

    Cheers,
    Mal.

    Unless you live on the beach, I wouldnt consider Sydney to be particularly humid - certainly not compared to Brisbane!

    A cupboard in a room on the southern side of the house such as a spare bedroom is a good location.

    Yeah Sydney is only humid if you compare it to Hobart.

    I live 1000klm north of Brisvegas and just 1klm from the coral sea. We get sauna like humidity this time of the year. Humid enough that you can taste it (the moisture) when you breathe and your glasses fog up when you go into and out of an air conditioned area. Just like a sauna! *;D

    That being the case, if I were to get into the whole roasting thing and start buying green beans is there a way to store green beans successfully in a tropical location or am I better off just purchasing a small quantities (a couple of kilos) at a time.

    vacuum storage, either in FoodSaver bags or barrels which you can put under vacuum through a pump?

    plastic/stainless steel vat/barrel with a good seal , and put a "Hippo" moisture absorber in whith the beans ?

    :-/


    5Senses roasters in Rockingham (no more than 3km from the sea-shore) store a lot of their beans in plastic vats, not unlike big rubbish bins, with lids which clip on.

    Re: Storing Green Beans

    Personally I wouldnt pack beans in a vacuum container (unless perhaps if theyre going into a nitrogen bath/deep freeze) or a plastic container. Commercial roasters commonly store beans in the big plastic containers, but those beans are quickly gone through before they can mold and the container then refilled. Long term storage of beans requires that they be in breathable containers stored at (ideally) about 20C and 50% RH with free moving air.

    For short term storage(less than 6 months) a cotton or untreated burlap bag and a cool, dry and dark spot are fine. For longer times I have had good success with the Foodsaver vacuum-canning jar method. I live in a place with much humidity. I put some Ethiopia DP in a cotton bag in the best possible spot in my house and vacuumed the rest in the glass canning jars in Sept. 06 and roasted some of both last month.and the bag stuff was flat and the jar batch was still quite good. George Howell has been commercially vacuum packing and deep freezing greens for a couple years now with great success.
