    Roasting blends?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all,

    I’m just wondering when everyone talks about coffee blends how do people blend their different coffee’s together? Are you roasting the two + type beans in the same roast or do you roast the beans separately and then blend them together? Is there a right or wrong way about doing this?

    Cheers,

    Chris :)

    There is no right or wrong way I think, its an experimenting game to see what works best for you.

    Pre roast blending and post roast blending there is benefits to both, a common example of post blending is roasting one bean type as a light and darker roast and then blending them together.

    For me in my small batch roasts I preblend because it saves time and effort and I get good results but I am yet to experiement with post blending as I think it may help more with small batches (250g and under)

    If you have the chance try both?

    Your first line says it all really doesnt it there is no right or wrong way. Like you i do smaller batches of coffee. A light bulb went on in my head when you said post blending and putting together a lighter and darker roast. Which may benifit both beans and there tastes.

    Exactly, a roaster can do whatever they like as long as it works for them.

    Frankly, you will read a lot of BS on the net about SOs and how you should roast each of them first, then blend afterwards. The theory is great and that is, that you roast each of the SOs to perfection in a way that best suits each one of them, before blending.

    Thats all well and good if the roaster has good expertise and the result tastes great, and if he doesnt have much expertise and does a crap blend, where does that leave all the wonderfully and single roasted SOs that he started with?

    All the above takes experience, exactly as that below:

    The other side of the coin is that the roasters experience leads him to be able to preblend and roast the blend in a particular way that also makes a great ( or crap) coffee.

    The only test that counts is what it all tastes like in the cup at the end.

    It also helps to have good roasting equipment and a wealth of experience. The more of each that a roaster has, the more possibility of success no matter wheher he pre or post blends.

    Hope that helps,

    I like post roast, as you can sample each as a SO before you blend and can play around with ratios etc.
    Great fun and interesting experimenting with it.

    Re: Roasting blends?

    Attilio, you make some great points. I must admit even though i have not been roasting long, i really enjoy it and want to learn more. Its all a bit overwhelming with all the different types of beans and how each one can turn out depending on the roaster, thier experience and also the equipment. Which leads me to ask what do you suggest as good equipment?
    At the moment i have a pretty steady corretto going, but feel something else may be a more relieable and more consistant. Any advice would be apprciated.

    Philby good point about doing to roast seperate, and instead of blending the whole lot blend some and of each and then you can sample all three :)

    Cheers,

    Chris

    Re: Roasting blends?

    I think most home roasters tend to pre-roast blend, more for convenience than anything else. Most of our roasters have a certain quantity of beans that is their sweet spot. My Coretto likes 600 grams of greens, which makes a neat 500 grams roasted. Just the right size. To try & do my favourite blend, which is 4:3:2:1 as a post roast blend would be a nightmare.

    4 parts Base.
    3 parts Highlight
    2 parts Tamer
    1 part Kicker

    Base. Ive used Brasil Santos, Brazil Daterra Opus 1 lo caffeine, or my favourite Indian Monsooned Malabar. Peru Ceja de Selva is a popular base amongst many CSers.

    Highlight. Something bright, with floral or citrus or fruity in the description. Usually something african. Ive only used Ethiopian Moka Harrar.

    Tamer. Something earthy. Maybe tobacco notes in the description. Usually Indonesian. Ive only used Sumatran Aged Late Pick.

    Kicker. Robusta for a little, kick. A monsooned Robusta goes well with the monsooned base.

    KJMs house blend
