    Another dumb question...

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Does anybody re-use their ziplock bags? Is the main reason that you wouldnt because of the residual oils present?

    BTW, its probably not the last dumb question youll hear from me! *:P

    Flo, not a dumb question....

    Yes, I do reuse them after careful cleaning - the best agent being alcohol to remove the old oils..... you might get away with a good detergent and a microfibre cloth scrub as well....

    But the bottom line is you must remove all the old oil and leave no moisture inside (hence why alcohol is so good)

    Re: Another dumb question...

    I use a glass jar, so does that mean that i have to wipe it down with alcohol everytime? i normally just wipe it with papertowl until i see no more oils. but it still smells.

    Re: Another dumb question...

    Is that Isopropyl alcohol youre using JB?

    If they can be re-used thats great-less plastic in landfill.

    Nope.... not sure if that would be safe. I use ethyl alcohol as per:

    As suggested by Mal ;)

    And if you get thirsty!!!

    Re: Another dumb question...

    I use alcohol wipes for the bags, have reused them over and over and the wipes remove all the oil. I am interested to see how long they last.

    For my glass jars I wash them with detergent when I do the dishes, rinse thoroughly and leave to dry. Works fine.

    Re: Another dumb question...

    Sort of like bowling balls. You gotta remove the oil, otherwise they get saturated, and stop hooking.

    I never use bags to hold roasted beans. I use washable plastic canisters and ice cream tubs. The only time i use ziplok baggies is when Ive weighed out a bunch of batches of greens for sample/blend roasting.

    Re: Another dumb question...

    Actually,

    Another thought came to mind..... If anyone has any friends or relos who have remained on the dark side and still drink instant, and their particular brown poison happens to be Moccona - That stuff comes in really great, resealable glass jars in a variety of sizes. To make them light-fast would be pretty easy, just wrap them in a suitable dark coloured plastic material or some such thing and Voilą.... Very nifty airtight storage jars for next to nix ;D.

    Or just go buy some home canning jars. Theyre dirt cheap and come in a variety of sizes and seal airtight. Not to mention because theyre glass they clean easily and dont retain flavors like plastic does. :)

    We have always saved a few for storage.

    My wife being the crafty type would probably take your idea Mal and cover them in some kind of decorative cloth with a coffee theme. ::)

    Hmmmmmmmm Marinated Canned Coffee Beans. . .

    Coffee Chutney perhaps? Pickled Panamaria, Mandheling in Muscat, Brandied Brazilian, Veracruz in Vodka, Sumatran in Schnapps - the alliterative possibilities are endless!

    Re: Another dumb question...

    Just a quick comment....

    If we assume removing as much air from around the beans (without applying a vacuum) is important to prolong their "life" for as long as possible.....

    Then using a rigid container - one which you cant squeeze out the air - doesnt seem like a smart idea (unless that container is full with beans - right to the top).

    I would think using the correct one way zip bags (which arent expensive and can be recycled) is miles ahead of anything else.... and that is why the quality roasters use them!

    If you want cheap and cheerful - why not use zip lock glad bags? You can do the same with them - that is squeeze out the air by rolling the bag towards the zip lock - and then zipping them up. You just have to make sure they are stored in a dark cupboard.

    The commercial machine trainer I had even stressed the use of the one way valved bags in cafes and squeezing out the air - and their turn over of beans is far higher than it would be at home.

    Advising people to use rigid containers (because of availability, price, convenience but with sacrifice in quality) is the same as advising people to purchase coffee machines with double wall (crema enhancing) baskets....

    One makes the coffee more stale than it should be - the other allows you to use that more stale (or even supermarket bought) coffee :-X :-X

    Re: Another dumb question...

    Great point JavaB, that is why I use the ziplock bags for freshly roasted beans to degas.

    Then once I start to use the beans they go into the canning jars which as Javaphile has noted are great for sealing and storage.

    Re: Another dumb question...

    I finally bought some valved bags on my last visit to Coffee Parts.

    I also reuse the bags I get with my roasted beans.

    Sometimes though the bags look too oily to bother trying to clean so I dont bother.

    Re: Another dumb question...

    To remove ALL the air, you can try the vaccuum pump that you use when re-sealing partly consumed bottles of wine - you know the pump-and-two-cork kits you get in bottle shops for about $20?
    That way you can use ordinary plastic bags, just give em a twist and Bobs your uncle. (I can hear the purists cringing from here!)

    Re: Another dumb question...

    I have used/do use several methods,
    Currently putting my freshly roasted beans into valved zip lock bags from coffeeparts, however I have noticed a tendency for the zip lock part to come off the inside of some of the bags, a bit too soon, meaning no seal,
    So reverted to the good old Moccona jar for my daily usage, NOW I thought about the light and air issues, and the daily use Moccona jar sits inside a stainless cannister, and I push a plastic bag into the jar to minimise the amount of air that can affect the beans,.. best compromise I could come up with at this time.

    Regards
    Bullitt

    hi javab,

    Gday DB,

    Yep, the stuff I bought was just plain Ethanol in a 1.0Lt brown bottle from our local Amcal Pharmacy. Ive bought it a few times over the years this way, even in a 4.0Lt bottle once. I guess the next best thing if you can find it would be really high proof Vodka..... probably more than 120% proof if its available. At least you know you can definitely drink the residue from one of these bottles ;D,

    Mal.

    hi mal,

    yeah, i went around pharmacies asking for this stuff and the chemists were either denying they have it or reluctant to give it to me over the counter - probably because of the fact that its 100% ethanol. something about scared of people downing it. will keep looking.

    I found a picture of closing options.
    http://www.northatlanticbags.com/resclosable.htm

    I get the pouch ones. The bottom opens out to increase the size of the bag and make a nice base to stand on. They seal with a ziplock.

    The gusset bag is designed to be heat sealed, but I roll them over 4 times and place a broad heavy duty clip on mine.

    I need to do a big buy of bags soon for the Fundraiser roast and will have heaps left over if WA snobs want to buy the extras.

    So are the zip lock ones; they have a section above the lock that is used for the heat sealing.
    After you cut it open you can then use the zip to reseal.
