    Bags Suitable for Storing Small Pouches of Coffee

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Ive been working on storing my roasted beans in small pouches (15g each) with an impulse sealer. But Ive yet to come across a material that is suitable for the purpose


    One way valve bags are out of the question as I plan to pack beans by dose.


    Ive heard alot about "degassing" and such, but it has never been a problem to me. For when youre usingg really cheap material like freezer bags, its easy to spare some space for the pouch to expand.


    Options:

    1) Typical freezer bag. Ultra thin, flimsy.
    PRO: Cheap and economical. CONS: Smell permeates THROUGH the bag! Its a weird burnt ginger smell that somehow gets through the plastic.

    2) Gladware Ziplock bag

    3) "vegetable and fruit" bag from coles/safeway/market. Thicker than a freezer bag.

    4) Vacuum sealer bag. Very pricey, but should be suitable.



    Any suggestions?

    Why would you pack beans by dose?

    It is not that hard to scoop out the required amount of beans from a one way valve bag

    Sorry Ezra it creates more work and to me at least does not make sense

    Seems a very complicated and inefficient thing to be doing "ezra"..... Why are you doing it this way instead of the more conventional and much more efficient 1-Way Valve bags? If its maintaining a consistent dose that has you worried, better to find a spoon or small scoop that contains the correct weight/volume or beans and use it to dose direct into your grinder. Thats what I used to do for several years and ended with very little or no wasted coffee...

    Well "Mal" :p i guess im just a lil anal.

    I consume only about 200g of beans a week. And to roast and measure and dose and pack and seal that much beans - even though i have to have two batches of roasting in a popper - takes well under an hour.

    So when i wake up in the morning, in goes the portafilter. Id take a shower and by the time im done I can open a pouch of beans and make my coffee ASAP and get to class in time.

    I know i may be redefining what it means to be pedantic... but if i can get it work properly with the right bags, Ill be guaranteeing freshness in each shot. So if i were using a one way valve bag, by the end of the week that bag would probably have been opened about 10 times.. so the last few shots would have arguably been exposed to much more oxygen.

    Im measuring my beans with a spare basket.

    I have some small bags (no valves) but they would be about 100g.

    I havent seen any smaller.

    If you are determined then small zip locks impulse sealed would be the way I guess.

    But why????????????????

    Why not do what I do?
    Use a valved bag lined with a freezer bag.
    You can impulse seal them several times before you run out of room to seal them.

    When it comes to coffee, Im probably as "anal" as the next coffeesnob. The advantage of the 1-Way Valve bags, is that you can squeeze out any remaining air after each coffee making session and I have never noticed any accelerated decomposition of the remaining coffee. In fact, with some beans/blends the brews taste better as the days progress.... ::)

    Anyway mate, its your coffee and its up to you how you want to store it and drink it.....

    All the best, :)

    Maybe you could think about airtight containers instead. Just wash and re-use.

    I think WotB has the answer small containers so one for each shot, with such a small amount of beans in each container you wont have an issue with degassing beans popping to lid etc.
    The downside is you are replacing time making the coffee with time to washup the containers

    If youre worried about opening and closing the one way valve too often and exposing the rest of the coffee to too much oxygen, why not just finish the whole bag?

    At 8 bucks a kilo of green coffee, go nuts!

    Roast two batches of the same thing, both into a 250g valve bag lined with freezer bags. Rest for 5-7 days.

    Open it once, take 1/2 out close the bag. finish the coffee, open it again the next day...

    thats what ive been doing :D or just finish the whole bag

    Thats probably why my coffee consumption is 1-1.5kilos a week

    I dont preweigh so i just pour beans into the hopper.....

    Ezra, I think being pedantic is probably a pre-requisite to being a snob here - I have no probs with a certain level of anal-ness when it comes to coffee storage & preparation, because attention to detail ensures freshness.

    However, frankly I reckon youre going over the top a tad with such minimal packaged weights. As others have said previously, the one-way valve bags work a treat in maintaining freshness for up to 2 weeks, release the gasses effectively, & are re-usable if washed, er, pedantically ::)

    Dont get too hung up on the thought that too much oxygen will significantly affect the freshness of your beans over a week - if stored correctly in a 1 way bag (& dry, cool, dark area ... in a pantry not a fridge) the quality is retained.

    Also bear in mind that most beans display at their best in terms of flavour anywhere from 5 to 10 days, relatively dependant on roast profile. If theyre too fresh, all you get in the cup is predominantly bubbly crema without the rich developed body that comes with patient de-gassing & resting.

    Like a good cheese or wine, let it mature a bit for the intrinsic flavours to shine. ;)

    Thats hilarious! ;D All rowed up like little logs. Fresh-roasted coffee snax!

    Those very small take-away containers that sushi places put your extra pickled ginger in would be about the right size, with nice tight fitting lids.

    But not nearly as neat 8-)

    Or as funny :)

    I love a bit of OCD. I can see it now...individual beans, packed in miniature, nitrogen-flushed, hermetically sealed, cryogenically-stored pouches. ;D

    Dont let us worry you though Ezra - do it your way! :)

    Re: Bags Suitable for Storing Small Pouches of Cof

    For a 1kilo roast I just put it in 4 or 5 sandwich size ziplock bags, each holds around 150-200g coffee. I keep the one I am using i a draw under the grinder for easy access, the rest are in my laundry cupboard (coldest room in the house, no clothes dryer or anything).

    Normal use goes through a bag every 3 or 4 days.

    I use LDPE or BOPP (Smell permeates through the LDPE unless you get the nylon lined ones.)

    What about cellophane, thats cheap isnt it? And works fine heat sealing.

    I think something re-useable is the way to go. Think of all those bags going into landfill.

    Re: Bags Suitable for Storing Small Pouches of Cof

    Hi all

    Well when I saw the pic that ezralimm posted I thought of some Woolworths stores where each apple is individually wrapped so that it retains its full freshness and is in a convenient user friendly size :-)

    By the way, when packaging in such small single shot amounts you will need to adjust the quantity of beans to take into account the aging of the beans over the week or so. So for instance for day 1 youll need say 43 beans, day two bags should have 45 beans, day 3 beans 47 beans etc. Also a think a pre-calculated grind calibration curve of grind setting adjustment for each days bag would be good.

    Best wishes
    Mike
