  • Dosing - Whats the advantage and how to with doserless grinder?

    Hey guys,

    I previously posted asking about dose to espresso ratio but think I got a little ahead of myself. I got many answers saying personal preference and varying amounts of coffee. But to be honest I dont think I understood dosing techniques and what the advantage is before asking... So backtracking a little....

    So firstly my technique currently is to pile my basket with coffee as I have a doserless grinder (baratza preciso), then sweep my finger NSEW to get a flat puck before tamping. I guess I thought this was dosing originally as I figure moving my finger around so my basket is flat on top is the same every time?

    So if I am using a double basket, after sweeping with finger, how could I possibly change the dose ( up) without first tamping- which I imagine double tamp to be problematic?

    Other than stronger coffee what dose dose affect? Pour time?, Blonding?, Strength?

    Is it acceptable to simply fill the basket then sweep with finger..?? To be honest I have never even weighed the result, just figured having a flat puck from finger sweep before tamp would result in the same amount each time!!!?

    Thanks again guys

    Hi hellofellow
    Sometimes up-dosing will be required with certain beans/roasts that you need grind a bit finer (thereby compressing more in the PF). I've found that by factoring in a simple settling tap on the bench before my NSEW sweeping gives me a good baseline - then if I want a bit extra in the PF, I just add another light tap. If I want less - tap lightly! That way, there is no double tamp required.
    I don't weigh either - this technique works pretty well over here :-)

      Thanks mate, but what exactly is the advantage of up dosing? Will it slow the coffee? Or make it stronger?
      Why when the coffee is finer, should you up-dose? What will it achieve in the shot pulled?

        If you are unable to perfect your grind so that you get your ideal pour (ie, one setting is too quick, the next too slow), modifying the dose slightly is a good way to "fix" your pour.

          You don't say whether you believe there's a problem with the resulting coffee?

          You have a method that you can apply consistently. That ticks box a). Whether this is optimal probably depends on what the dosing level is in the basket after tamping. The top of the puck should normally be very close to touching the shower screen (the height of which varies by machine). It's far from perfect, but you could do worse than try the '5 cent test' (search this site) and see what your dose level is like. I know that if I applied your technique on my machine in my standard baskets, I'd get an underdose, but this doesn't necessarily mean that you are underdosing. If you find that you are dosing too low, then dosing to a mound, tapping, dosing more before/after your sweep etc will help you develop another repeatable technique. Don't try to religiously copy any video you find on the net in terms of number of taps etc, because your shower head height etc may be different.
