    I have never experienced what you describe but perhaps if you can give us a bit more info on your roasting setup and maybe a few piccies, that will help us to help you...

    see I always get two total different ends of the spectrum, it's such an even sized bean too.

    Here's the roast setup. It roasts quite even with other beans. Thanksimage.jpg

    By the look of the picture the beans look a little over done. My preference for these are to be roasted a little before second crack on a steady yet moderate heat. Even dropping the beans prior to second crack i have found that some are darker than others. If it helps the beans in your picture that are lighter, thats the colour i would be aiming for.

    I have read online a few places saying they are not the easiest bean to roast, that may have to do with the appearance of the end result more than the taste. I dont worry about the mixed colours however i do follow a profile that ensures i drop them before second and that i have the flavours right. I let these sit atleast 4-5 days.

    Kind regards,

    Chris

    Have never experienced this with MM, in fact I find it one of the easiest SO Arabica's to roast, always turns out very evenly for me.

    Looking at your pic would lead me to wonder if there are two different varieties there! the darker beans look to be over done and the lighter ones underdone.

    I thought the same thing. I'm not super experienced but I found the MM really easy to roast albeit a little different to other beans but easy none the less.

    Could end up being an interesting blend in the cup - combination of different degrees of roast of the same bean. Could end up a winner. Generally I find MM to need a longer rest period as well.

    Seems like the heat distribution throughout the batch is not being evenly conveyed.

    It's a bit difficult to tell from your photos but I imagine you have sufficient stirring vanes located throughout the roasting drum? What is the rotational speed of the drum (rpm)? Also, how is the heat inside the oven circulated, natural convection or fan forced? Fan forced would probably do a better job. Lastly, what sort of batch size are you roasting? If the batch is too big you may not be achieving a thorough mixing of the beans throughout the batch.

    +1 to this. I did the exact same thing (probably not as dark a roast as yours) but in a corretto in my garage. I decided to turn a standing fan on to stop myself from roasting also but ended up moving all the hot air over the open corretto and gave myself quite a varied roast.

    Yeah Mal,
    It does appear that the heat isn't evenly distributed... There are 3 "vanes" in the drum, the RPM is about 30/min; unfortunately no fan in there, just 4x heating elements - 2 top and 2 bottom; interestingly I was having trouble with uneven roasts whn I was doing 300g green (to yield 250 odd), but since bumping it up to 450g green all my other roasts have been really quite even! Only the Indian MM has consistently been black and white.

    I will try 300g next time to see if that makes any difference.

    Cheers Mal

    Yeah true story Graham. I only wish I could compare with an even roast...

    Yeah I know Chris, one bean is overdone yet the others almost green! A long rest period for this bean is essential.

    LukeMC and Yelta, the plot thickens. For me, all other beans are fine, but every time the MM is multicultural.

    I looked back at your original post and there could be many reasons why there is a variance in bean colour when finishing the roast. With that all said you also mentioned it comes good after 2 weeks and that i feel is the main thing when roasting. If its good to you and those drinking it the colour difference may not be a big issue. I use this bean in most of my blends, purely because of the crema it creates. To me it also has a interesting taste which can also compliment a blend. I do find if i do go to second crack with this bean, it begins to get sheen to it rather quickly.

    Regards,

    Chris

    The roast does look uneven, but I have found MM to be pretty easy to roast - and it seems to taste great no matter what. Being a monsooned bean, it does crack quickly. I think I'm in the minority but I think it's one of the most chocolatey SO beans you can get. I love it. And it certainly benefits from a few days' rest before you drink it.
