    Wasting new beans finding new grind setting.

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Anyone have a hint or a trick they use to find the new correct grind setting when getting a new bag of beans?
    Getting sick of wasting 100's of grams of beans finding the right grind setting when I get a new bag of beans which usually fortnightly.

    Thank you

    Hundreds of grams? This is outside my experience. Surely if you have weighed and timed your previous optimum then you would have a good approximation of what adjustment is needed after the first shot, which you also weigh and time? The third shot should be enough, usually, allowing that the final adjustments are for taste rather than to reproduce exactly the original measurements.

    Alternatively, maybe that is why they invented stepped grinders (fewer choices = less wastage)

    Which beans and when were they roasted, what grinder and what machine? It takes one (OK sometimes two) 18g shot/s to dial in a new bean on my set up, then there should be very minor tweaking only, to maintain consistency etc.

    Excuse my hastily written, over-exaggeration. Id say im wasting about three pucks before getting the grind setting correct which I consider 30ml in 27 seconds. Im finding in the period of a fornight the grind setting generally starts finer and is constantly ever slightly adjusted to coarser as the beans get older. New beans arrive and the grind back a fair bit finer, that’s my experience anyway,



    Beans are generally three days old when bought and are 500gr Goodness Galileo from Coffee alchemy.

    3 days post roast? Probably haven't finished degassing.
    How far off your desired yield/time is the first shot?

    How long have you owned the set up, I find after working with a grinder/machine combo for a short time its pretty easy to figure out grind settings for a new batch of beans, the first shot may be a bit tight/fast the second usually spot on, certainly no sink shots.

    i find that my setting starts coarse and over a week or two it needs be a step or two finer with the possibility of adding 1 gram by the end of that batch. Generally takes me two - three pucks before I get it right. I also try and not change my beans too much, unless I'm bored of them

    As the above poster 'Far' notes, it's typically the case that one needs to make the grind a little finer as the beans age. I can't recall needing to make the grind coarser as beans age (holding all else constant). But, yeh....if you are starting with 3 day old beans there might be a little unexpected variation in the first few days.

    I'm surprised that a well used setup causes that much dramas. I find that even if the first shot isn't quite as perfect as it could be it is rarely if ever undrinkable. The only adjustments for me is a little coarser and more or less time for the grind. Maybe start roasting your own to eliminate another variable.

    I waste a bit when I switch to a to me unknown brand. I do have been told that you make the grind courses as beans age. Never really worked for me though

    The grind will need to get finer as the beans age

    It certainly will, not by much though, I always find my Mini a couple of clicks finer at the end of a batch.

    I doubt it’s the setup, but rather knowledge on how to get the best from it.

    Agree to a point.
    As the beans age further they can benefit from grinding coarser and up dose

    Has never been my experience.
    Have always found that the best results in the cup come from grinding finer (as required) and dosinging correctly...

    And that’s why this industry is great, so many different opinions.
    None of them wrong either but all subjective to what the drinker likes in the cup.
    From all different brewing options at home to commercial roastery with all the tech analysis gear, I’ve been lucky over the last 10 years to work with some of the best in the county, from green suppliers, roasters and q grade palates from which to try to understand why they can get more from the beans we drink.

    Grinding finer or coarser as required and dosing correctly

    Thank you
    * Make a small pile of grinds (about half a teaspoon) from your outgoing beans onto a sheet of paper.
    * Make a similar pile of grinds from your new beans next to the 1st pile.
    * Rub a pinch from each pile between your fingers.
    * Adjust the grinder, up or down, until both piles feel the same, at which point you should be in the right ballpark.

    Ps trust your fingers, they are surprisingly sensitive.

    Ps 2 works especially well after disassembling some iffy grinders for cleaning.

    Have found that using the above method, standard Table Salt is not a bad analogue to use when setting a grinder up for first use...

    Sometimes you've got to over-exaggerate to get your point across. I've been told millions of times not to do it, but I still do.
