    Blending - rookie question

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hello dudes and dudettes,

    I have a beginners question on blending.
    Do you roast each single origin separately and blend as roasted beans or do you blend the green beans and roast the blend?

    I have not delved into my own blends as yet, but I have a kilo of Monsooned Malabar on hand and have been reading that topic with great interest.

    Hi Brett,

    You can do either, depending on your own tastes, and the desired roast profiles of each origin.

    I believe that each origin should initially be roasted separately and cupped, until you have a clear idea of your own preferred roast for that particular coffee. Once this is done, you can then "pre-blend" this coffee with any other coffee(s) that have the same desired roast profile.

    To give you an example from my own personal experience. I am currently experimenting with the following blend:

    20% Ethiopean Harar (roast - 2nd Crack)
    45% Brazil Cerrado (roast - 2nd Crack)
    35% Sumatran Mandheling (roast - 2nd Crack + 35 secs)

    What I do here is pre-blend the Harar and the Cerrado, since they have the same desired roast level. The Mandheling is roasted separately, since it has takes a darker roast.

    A handy hint I picked up a while ago - pre-blend your coffees at least 24 hours prior to roasting. This allows the varying moisture levels of each origin to equalise with the other constituents, thus allowing a reasonably uniform overall roast.

    As you are starting out with blending, I suggest getting some high-quality Brazilian coffee to use as the base coffee of your blends. CoffeeSnobs is currently running a poll of the Brazil Cerrado (the best Brazilian widely available in Aust.), so Id recommend snapping up a few kilos asap.

    btw, I did a post of espresso blending a couple of weeks ago. Check it out, it may help you start out on the wonderful world of espresso blending -

    Experiment with using the Monsooned Malabar as a base as well. I hear that it does very well. Try starting at 40%, and increase or decrease proportion as needed. I have no experience with this coffee, so I have no real advice to offer.

    Graeme and Avi, thank you very much for the responses. Im still using my Imex for roasting, so I might do some experimenting with blending post-roast.
    I have put in votes for a number of the polls which have just happened, so I will be able to try a few combinations once the beans arrive.

    Ill be like a kid in some kind of shop!
