    Hopper vs Jar

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Im looking for experience with storing coffee in Grinder hopper. Ive got a Rocky Doser and use about 250gms of beans a fortnight. Up untill now, I keep beans in an old mocona jar with the sealed lid. Each time i make a coffee, i measure beans for the basket im using and grind that amount only. Ive read, somewhere, that it is better to grind with a full hopper and it would certainly be more convenient to keep the beans in the hopper. My question, has anyone experience with keeping beans in the hopper for about 2 weeks vs keeping in a jar as i currently do? Is the air exposure in the hopper any worse in practical terms vs the jar?

    If the jar is not airtight you could do either. I store my beans in the vacuum bags or a container that I pump the air out of the create a vacuum.
    Air contact with the beans makes them go stale, they only have a life of about 3 weeks after roasting so storing them properly helps keep them as fresh as possible.

    Whilst air oxidises the coffee oils and makes the beans taste rancid...... the oils which are so precious are volatile.... they evaporate easily..... put them under a vacuum and you have just sucked out those precious oils!!! Well at least they wont go rancid!!

    A bag with a one way valve and squeeze out as much air as you can.... then into a cool, dry dark place.....

    No vacuum, no open containers or sealed containers with lots of air space :-X :-X :-X - not if you value your beans!! PLEASE

    P.S. and in case anyone misunderstands the word "cool" it does NOT mean a fridge or freezer.... they are "cold" and will cause condensation which is also bad!!!

    I have the perfect solution Argon.

    Drink more coffee so you use up the beans quicker. :)

    My problem living on the Sunshine Coast is finding a cool place during the summer months. I usually go through a 250g pack in a week though so its not too much of an issue.
