    Valve bags and resting time

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hello

    This might be a question that has been answered before, but I will put it out there anywhere...After everyone has roasted how long do you wait before putting your beans in a bag with a one-way valve? As soon as they have cooled/\/a few hours/\/a few days? Also do people re-use these bags or is there a chance that oils from previous use might spoil/\/go rancid and ruin the new roast?

    Cheers

    Rohan

    First question - good one, Ill be interested to hear.
    For your second question, check out http://coffeesnobs.com.au/YaBB.pl?num=1198012775 If I recall there was another thread on this topic around the same time so maybe do a site search on bags or something and see if you can find it.

    I put my beans in the bag as soon as they have cooled down and put them in a dark cupboard to degas. I re-use the bags until the zip starts to fail, I clean them out each use with a dry cloth to remove any residue and oils.............................................

    Re: Valve bags and resting time

    Ive started lining my bags with small freezer bags.
    I should be able to use them until the zip fails without ever having to clean them.

    Re: Valve bags and resting time

    After a dozen tosses back and forth between seives,.. I pour and spread the beans out on the kitchen bench. The granite brings them down to cool very fast but I leave them there for about 10mins then pack em away in valve bags now that I finally have a few.

    I was panning to wash them out with warm soapy water, but I liiiiiiiiike the freezer bag idea. Good one TG!

    I pack them in the bags as soon as they are at room temperature..... probably 10-15 minutes post roast.

    The bags get washed out with water and an Enjo wipe between uses and dried on top of the coffee machine - only being retired when the zip fails.

    I tried soap and water a few times but its a PITA and the valves must take a bit of a beating from it too.

    My hands are too big to wipe them out with alcohol.

    Remy Im going to have to start charging you for all my ideas you use. ;)

    Re: Valve bags and resting time

    Probably red rag to da bull, but I like to leave my beans for their first rest, for 24hrs in open ice cream containers......the main reason? I want everyone in the house to experience the smell....PLus if I have to wait to consume them, this may save a day or so.
    To be honest though, I reckon there is more gas released in the 4-10 day zone than those firrst couple.

    Re: Valve bags and resting time

    Ive been curious about the relative pros/cons in letting the roast rest uncovered for a while as well.

    Generally but (after letting the aroma develop a bit and waft around the house - 5 to 10 mins after cooling ::)) I bag them and stick away in the pantry.

    I clean my bags out with alcohol wipes then a clean, dry tea towel. Use until the seal goes or they get a bit too ratty from too much squeezing of the CO2 out.

    What about vacumn coffee storage containers, Good ot Not?

    Do they sweat in vacumn sealed containers even after one way valve bagging for first 48 hours?

    redzone121....

    The oils in coffee are volatile - they boil off at room temperature and under atmospheric pressure - the coffee going flat and dull in flavour....

    Put them under a vacuum and the boil off faster - you are in fact sucking these oils out....

    So bad, bad, bad!!

    My opinion is NOT.

    Vacuum containers SUCK the oils out of the beans and age them faster IMHO.

    Mike, Hi and welcome

    Coffee [s]hit[/s] parts (sponsor...see site sponsor to the left <--) has valve bags and so does this site aswell.
    If you go to "Green beans" and "Other stuff" you will find them.

    Hope this helps

    -Linda

    small edit note: Thank you TG, I made a small mistake there. Coffeehit doesnt sell the valve bags. Long day at the office. *;D.
