    Best way to package freshly roasted coffee?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hey guys, I've been a lurker on this forum for a little while, trying to steadily absorb all the information I can about the wondrous coffee bean! Firstly - apologies for starting a new topic, I did use search but couldn't find much information regarding what I was looking for.

    I've recently started experimenting with roasting my own coffee for family and friends. Most of the coffee I roast gets consumed within one week of roasting. My knowledge of coffee is pretty basic and up until now, I've sealed coffee in simple paper bags however I would like to invest into some proper packaging and maybe even a sealing machine.

    After researching online I've found the most common types of bags are either vacuum sealed without a valve (doesn't allow the coffee to degas) or one-way valve (valves have a slight fail rate) in either a gusset (I don't 100% understand what gusset means) or pouch design. From what I can tell these bags are either vacuumed or heat sealed (sometimes with heat or impulse sealing). What I am looking for is the best possible solution to keeping coffee fresh for roughly 1 week.

    I'm currently looking at 500g one-way valve gusset bags (can these come with zip locks too?) that can stack like bricks or perhaps 500g one-way valve pouch bags with zip locks. Would any coffee snobs be able to provide me with some feedback perhaps? Or better alternatives? Also, I'm stumped with what is the best form of sealing machine/solution?

    One alternative question: if I receive a friends coffee in a vacuum sealed bag (1 or 2 days after roasted) but he does not have a one way valve on it - what type of damage would I do to the taste of the coffee by opening it to the atmosphere and resealing it in my own valved bags?

    I appreciate all the help in advance!

    One-way valved bags are the way to go (like the ones they sell on this site - check the BeanBay link at the top of the page). They have zip locks on them - no need to heat seal them. Smaller bags are better (ie. I prefer to use 2 x 250g bags instead of one 500g bag), as you are exposing less coffee to the air each time you open a bag.

    Definitely one way valve bags as bill said. Package the coffee within 24 hours of roasting then let sit for a week in bags!

    hmmm? .. I don't know where you got the idea that a sealed bag prevents the beans de-gassing ? It's just not true .
    Try it for yourself.

    I find it hard to believe your friend vacuum seals the bag 1-2 days after roasting. In order to do a proper vacuum seal, (without the bag blowing up with C02), it would need to be totally de-gassed, by which time it would be close to stale.

    Use the tried & tested Valved bags as suggested below and which Andy sells in BeanBay. They work, that's why virtually all speciality roasters use them.

    Also I suggest you do a search on this forum for the countless posts regarding roasted bean storage.
