    First and Second Crack

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Ok so here’s one for the discussion thread. After doing some reading from another US forum website that provides a visual guide to the roast process, why it is here on this forum does the emphasis on time between first and second crack be so different.

    From what I have read over the years on here the general rule is to aim for 4-5 minutes between FC and SC. This is to allow for sugars to develop etc etc.

    My point of discussion is, why on this US forum, and I quote "The whole stage between the first and second crack is a short period (15 to 30 seconds) where a lot is happening chemically to the beans" be so different. Also when you read the article and look at the times, the times from the beginning of FC to the beginning of SC is only 1min30sec.

    I ask for this discussion because if you know the site, they, like Coffeesnobs, are very passionate about their coffee.

    Hello Brew Time

    If Im not mistaken the article you refer to (from Sweet Marias) describes an increasing, linear application of heat. The article describes the process, or perhaps better to say, the transition, but I dont think its a recommendation on how to roast coffee.

    Re: First and Second Crack

    Hi all,

    Its an interesting question - Ive read the Sweet Marias guide before - is that the article you are referring to Brew Time? Do you have the link - would make it easier to discuss.

    From my personal experience using the Behmor roaster, I originally used the normal method which leads to approximately 2 minutes between start of 1st crack and start of 2nd crack, but recently have been using the method mentioned by Mal if I remember correctly where you open the door slightly with the brush and create a longer pause between 1st and 2nd crack, closer to 3-4 minutes. Ive found with that method on the last 20 roasts or so, that its been more predictable getting to the end result that I want without the beans running away at the end.

    Cheers,

    Jonathan

    Times mentioned above are for 200g of beans. Would be longer times for larger roasts...

    Hi Dennis

    Yes you are correct with what article I am referring to. I not 100% on what is allowed to be mentioned with other sites etc within this forum, hence why I didnt mention the site name.

    That is soooo wrong. The time should always be 1 minute 28.5 seconds if the prevailing wind is from the East, I cannot imagine what a 1:30 roast would be like.
    ::)
    (sarcasm end)

    As a roaster you need to understand what works for your equipment and taste preferences. I have seen some amazing coffee (amazing they could sell it) from people who are electronically very verbal and sound like they know what their are doing all over the world.

    Roast yourself two batches, one with 1.5 minutes between the cracks and another with 4 minutes between. Rest, taste and make notes what you liked and didnt like about the two.
    ...and then you can answer your own question!

    There are many ways of getting to the finish line, none of them are correct and some of them are great.

    Re: First and Second Crack

    Im glad you brought this up, Brew Time, because I was trying to figure out the same thing.

    Ive got to the point where Im heating evenly and getting to first crack at about 9 minutes (give or take, depending on the phase of the moon or something :b ). At this point, I have started to ease up the heat and wait for the beans to go through to where I want them. I aim for another 6-9 minutes.

    Partly for the sake of establishing common terms, Id like to know how CSers generally describe this stage of coffee roasting. Do you consider it as being from the very first crack, which wont be followed by the next crack for maybe another 30 seconds, or do you count this stage as having started when the pops are coming fairly steadily?

    What difference does it make?

    - Andy you have nailed this one right - lots of ways to make coffee that somebody likes (and it seems there is no accounting for taste).

    That being said, after a lot of experimentation and a lot (but not enough) browsing of the coffeesnobs threads, I have found that there are some general guidelines for times and temperatures that have made my coffee a million times more palatable than it was eight months ago, both to myself and my friends at work who are gracious enough to continue buying my coffee and funding my little hobby.

    I hope that I havent hijacked this post too bad, but Brew Time has asked someting that is on my mind a lot lately.

    Youd think I would get paid better

    Somewhere in between.
    (When a few early cracks can be heard close together.)
