    Bean longevity

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Quick question.. and apologies if this has already been discussed before but I was wondering how long roasted beans will normally stay usable for (both as unopened packs and packs opened).

    I have read reports of anywhere from 5 days to 30 days.

    Cheers all.

    G'day Alastair,

    Preferences are involved, however most of us like to allow beans to degas for about a week after roasting before consumption.

    In my opinion they are at their best from about 7 days post roast to approx 3 weeks, and still quite drinkable at 1 month, from this point on they deteriorate rapidly.

    All of the above is dependent on correct storage (one way valve bags) in a cool dark place.

    No, storing in the fridge or freezer is not a solution.

    In answer to your question, yep, would like a dollar for every time the topic has been discussed on this forum.

    Would vacuum packing extend this period?

    There's a whole section devoted to the storing of roasted beans: Roasted Bean Storage

    This is a good thread to start with: http://coffeesnobs.com.au/roasted-be...ted-beans.html

    Thanks! Didn't want to start a new discussion, I was just surprised by all the conflicting suggestions.

    I always learned rules of 15 ; 15 months for green beans, 15 days for roasted and 15 minutes for ground. Very rough rules of thumb in any case.

    Agreed. I have also heard a variation on the "15" rule to be the "2" rule. 2 years green (arguably a lot longer if kept correctly), 2 weeks freshly roasted (plus a few days resting) and 2 minutes ground.

    2 minutes ground is probably a little stringent, but it enforces those who purchase beans pre ground (particularly from the secondary supplier like a supermarket) are kidding themselves if they want fresh coffee.

    Rule of three
    3 years green
    3 weeks brown
    3 minutes ground or 3 seconds depending on how CS you are

    Re the 3 years green, always try them regardless. I had beans way older than that and stored in unfavourable conditions and they were still great.

    Cheers
