    Black eyes on my Monsoon Malabar AA Arabica!

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I had a totally wierd experience tonight roasting my Monsoon M AA. It is a cold night and I let the second crack go for a while longer - temp hovering at about 232 degrees. All of a sudden these tiny little brown disks started appearing on my roasting table; hundreds of them. I pulled the beans off the roast and cooled the beans. To my horror every second bean had a little black hole in the side of it. Further investigation of the beans revealed that they werent too charred on the inside with the outer bean colour about 2-3 off the top of the CS scale.

    What is this phenomenon? Have I ruined my roast?

    I just noticed raphec had the same problem a couple of days ago... THere you go, one persons worries is another persons worries. Perhaps we should compare our cups in about two weeks. Good tips about only roasting light with the MM.

    Divots theyre called. Do a search on them. I usually get them when I roast deep into second crack and into rolling second. Most of my roast at pulled just at the first snap of second crack so I dont get them much. With the MM, I find it best when pulled at the first snaps of second crack and no further. I did one a bit deeper, pulled at the first signs of rolling second, but it didnt taste as good as the one I did pulled at the first snaps of second crack.

    Re: Black eyes on my Monsoon Malabar AA Arabica!

    i roasted about 550g of the monsoon malabar, half is in my grinder and notr very good, the other half has been sealed away waiting 2 weeks to try but i wont have it sitting there without anything in reserve next time.

    I was too enthused about roasting, and fresh from my earlier success, so i just assumed it would be ok.

    On the bright side, tomorrow i should be able to chuck in the kanga gesha as i roasted it on monday.

    OVer the week the malabar has improved slightly but its still not terribly good. I didnt realise id need to leave it 2 weeks.

    live and learn.

    I always stop my MM roasts at start of second crack with CS 5=7 colour range. I have been using them after 9 days and getting wonderful espresso and milk drinks. I take it out long and slow with fc at around 14min and start of 2nd around 19-20min mark and get good results each roast.

    This is not a good way to store roasted beans raphec.... Theyll age too quickly and become stale in far too short a time frame. Much better to store in 1-Way Valve bags in a cool, dry and dark place with reasonable ventilation.... back of a cupboard or similar but never in the fridge as condensed moisture is another enemy of freshly roasted coffee beans.

    Cheers,

    The taste might not be optimal, but I love the monster crema you get when you use beans straight out of the popper

    oh i didnt go straight from roast to grinder, left it 3 days. But yes the rest is sealed airtight (in a taped up freezer bag also sealed in tupperware) in the bottom of the pantry.

    Will check it out in a week or so.

    You might want to let the CO2 gases out once in a few days.

    The point of the one way valve bags is that they let the CO2 out and dont let the air in. I reckon that they are also good because you can gradually empty the bag over a week or so, each time resealing it and wraping it up with a rubber band so that there is as little air in with the beans as possible.

    No they have a plastic zip on them that re-seals, you then squeeze out the air and place in dark cupboard.

    Well, if you really want to keep air out, then yes, you do. The ziplocks arent by any means air tight. Some people use an iron as a method of sealing the section above the ziplock.

    Only problem with any heat sealer is that it will restrict your ability to re-use the bag. Try it and I guarantee youll notice a difference.

    Ive found that the "Zip-Lock" does a fair job while the bags are relatively new but after a few uses, as Dennis says, they lose the ability to remain really air tight. Its at that time that I use my little impulse-sealer (only uses a 3mm wide heating element) and if Im careful, I can get another four uses out of the bag but I think itll be an awful long time before I recoup the cost of the impulse-sealer at that rate. Really do it to save on throwing away plastic bags, so from that point of view, its worth doing.... 8-)

    I do the same.
    When the ziplock starts to look a bit suss I impulse seal the bag as high as possible and then put the beans away for aging.
    I can then transfer them to a newer bag for everyday use.
    This gets me a few more uses out of the bags towards the end of their usefulness.

    I have had my suspicions that those zip bags leak air once you have reused them more than a few times...

    How well do the pump action jars work? They are pretty dear for what they are are they worth it? Which brand is the go?

    The jars arent recommended because they create a partial vacuum and draw out the oils from the beans faster.
