    Roasting and Storing

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi,

    Completed a few roasts so far with HG/DB...

    What do you do when the roast is complete...
    like how long do you do beans need to degas... how do you go about letting them degas?
    and storing beans after this?

    The reason that I ask is because I often stop when 2nd crack just begins and before it really rolls on... and after storage (at least a day) Ive found that some beans that Ive store have shiny moisture on them?
    Could someone tell me why this happens and what is it?

    Ive have this happen with other beans that Ive bought and put into a sealed plastic container.
    Any help would be greatly appreciated.

    Re: Roasting and Storing

    A roast can really be complete at many points.
    At least rolling 1st would need to be complete, and most beans would need to go a bit further as a minimum.
    Take an example roast where 1st crack began at 12:00
    Rolling 1st @ 12:50
    2nd @ 18:00
    Rolling 2nd @ 19:00

    The roast could be complete anywhere between say the 15:00 and 20:00 mark depending on how dark you want the roast.

    Personally, I take all of my roasts to 2nd crack and many to rolling 2nd, but the more experience you have with a specific bean (and keep records of your roasts), then you will be able to try to complete roasts before 2nd crack and see how that affects the tatse.

    Degassing can be different depending on the bean. General rule of thumb is 48 hours. Can be shorter or longer. Most beans taste continues to change from roast to 12 days. I generally aim for days 4-8 as the optimum days.

    The shiny moisture is oil from the coffee bean itself. A darker roast will bring out the oils quicker. IE: if you go rolling 2nd + 30 seconds, the beans will most likely be shiny as soon as you finish. Lighter roasts can and do develop oils as they get older. Perfectly normal.

    Hope that helps.

    Brett.

    Thanks heaps... got you on the de gasing time frame.
    How do you de-gas in a bowl in open air?
    When and how does one store the beans best from each stage?

    The oil appears not during the roast but later, only a few individual beans like it is sweating, occured about a day later. I felt like I store them in a closed container too early. Could that be right?

    I just put mine in a Maxwell & Williams cannister. I open it a couple of times over the first 48 hours (usually start drinking after 24) so that lets the CO2 out.
    Many people use glad zip lock bags with a pin hole in them. There are also special coffee bags with one-way valves you can buy, but that might be overkill.
    Generally, I think its best to keep them in a sealed container out of direct sunlight. If you have a LARGE volume of beans (over 1kg), you might need to look at other options. I recall reading an article by Alan Frew which mentioned a lid bursting off a tin in his car boot due to CO2 buildup. But I think he was carrying quite a lot in the container..

    I put them straight into my jars next to the coffee machine. Any excess, I put into the coffee bags with one-way valves and store in the pantry until ready for use.

    Oils appear over time. If you roast to just on 2nd crack, the beans will probably not show oil immediately, but it is perfectly normal for the oils to start to appear after a day or so. If they last a week, youll probably see a bit of oil on most of the beans. Nothing to worry about re: storage.
