    An interesting pre-roast blend observation…

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all
    Just something interesting Ive noted the last couple of roasts…
    Ive had some disasters in the past with getting a consistent, even pre-blend roast (eg the KJM house blend) - ending up with a mix of light and black varieties on occasion :-/
    But Ive recently ramped up my input temp before first crack (bringing 12-13 mins to first crack down to 10mins in the process) and Im getting a much more even roast - I now cant pick the varieties visually.
    The other interesting thing with this faster ramp has been that the temp for second crack has been extended. Now second crack is coming on at a higher 224-225 - 2-3 degrees higher than my traditional drop point, but also with a lighter overall colour than before too.
    And great in the cup and off the grinder!

    Not world changing by any means - but very interesting nonetheless… hmmmmmmm :)

    Happy roasting!
    Matt

    Hmmm - the "KJM Blend" is usually 10 or so (depends on how cold it is!) minutes. Ive always been surprised at how even it is. I might have a go at extending it to see if I get spotty results..

    Id love to know how it is that the roast of such a diverse mix can end up so even. Very interesting data point there Matt. Youve re-piqued my interest in sorting out what is going on!

    Yeah - I was surprised too! Id almost resigned myself to SOs after the first few salt & pepper blends I did - but the faster climb seems to do wonders.
    Last night I did a blend of Brazil, Columbian, PNG & Uru - and even the soft & small Uru was pretty consistent in colour depth to the others - and that was always my Achilles heel before. So - in happy land now! Blended roasting here we come!

    I like to tinker when I blend, so I will roast the coffees individually, and blend on a shot-by-shot basis. I also think that if youre going to bring any funky coffees, such as robusta into the mix, you should definitely try a shot of each ingredient.

    Quite agree. It is the only way to do it. BUT once youve nailed the thing - co-roasting gives an interesting flavour twist. And its just easier ;D

    Hi MC
    I must admit, Id really like to potter a bit more with post-roast blending of SOs, but with a corretto that has a minimum batch of about 350g (a weeks worth for us), doing 4-5 SOs would be counter-productive - Id be blending stale beans for months (and a full day of roasting would no doubt destroy my marriage!)
    Maybe a modded popper needs to be on the cards… ;D

    But now Ive got my profile consistent much more consistent & in-the-zone with this technique, the flavours keep getting better and better ;)
