    Dynamic Blending

    Hi all,

    I have been using a technique I'm calling dynamic blending.

    What does this mean? ...well, I have a 2 grinder setup.

    The LHS grinder if full of a killer bean. That's the bean with punch and unique characteristics. Right now that's Yemen Mocha Ismaili.

    The RHS grinder is full of my single origin of the week.

    So what's the dynamic part? Basically, I grind different ratios every day.

    For example, this morning I ground approx 10g for the RHS grinder, then 5g from the LHS grinder, then another 5g from the RHS grinder.

    Tomorrow I will try another ratio. I get a different blend every day

    You don't need 2 big grinders for this. Try the same, but use a hand grinder for your middle "killer bean" layer.

    Interesting concept, I sometimes use an espresso blend or single origin and add 25% lighter roast and mix them together and then grind, produces some interesting results!!!

    Good in theory if they will extract at the same particle size.... Out with the refractometer to see what's actually in the cup ...

    Hope you're well gm...

    There are 2 reasons for the dynamic blending approach.
    The main reason is to get a little more variation in the daily espresso. eg, no Yemen one day, 10% another day and 30% another, and so on.
    The second reason it that I don't want to waste my Yemen on latte drinkers, so when I have visitors wanting lattes they have to suffer with my SO alone.
    I find that if I get the get the grind size for the Yemen in the LHS hopper just right for full Yemen extraction, I can leave it as is and control the back pressure using the SO RHS beans.
    I hope that all makes sense
    Cheers, Paul

    You certainly don't. You just need two bags of beans and a bowl in which to mix them on different days

    That will do the job as well Barry. I used to do that a while back when I single dosed, and yes, for single dosing the dynamic blending method isn't relevant at all.
    Now I'm a full hopper guy (weighing after grinding, not before), so that's why this method works for me.
    Cheers, Paul

    Sure. I don't single dose, but I only put enough in the M4D for the day's use, plus enough surplus to ensure that the last grind doesn't popcorn. In fact, I'm 'dynamic blending' presently as I had a bit of a Garry while roasting the Indonesian C's and am experimenting with the best use for them.

    Goes back 20+ years, but nevertheless good fun... I recall experiments in cafes I played in back in the early 90s with 2 grinders used to deliver half-caf...

    2 grinders for half calf... That's a good idea Chris. Good for an evening brew

    ....I thought about my technique and decided to change from having the Yemen layer in the centre to having the Yemen layer on the top. This makes mores sense as having 2 layers instead of 3 means less variation.

    Today I amazed a customer away when he experienced shots with 0%, 15% and 30% Yemen. I think we have a new Yemen fan

    I couldn't help myself this morning Paul. With all this talk of Yemen going on I cracked open my bag of Ismaili at day 9. As suspected, it hasn't rested enough. Needs 14 days I find. Closed the bag up and back to the Limu Kossa! First world problem if ever there was one!

    and the first gram or two of the 5g from one grinder is probably yesterdays grind....... I would run an empty hopper mix what you like and then drop them in as others have suggested already

    Great point Justin.
    Run an empty hopper and the top up bean or - purge.

    Glad you enjoyed it. The secret is the Yemen. What a difference a little Yemen makes
