dfk41 Still the same 1:15 ratio, is it not? Personally, I won’t worry as it will give me more coffee in the morning! 😊

    dfk41 Grind size and brew ratio are the same. There may be a small time difference between 270g and 300 in terms of total brew time. You shouldn’t see a quality difference.

    dfk41 Patrick told me he is getting strong orange from his Wush Wush…is he taking the mick!

    He is correct. Orange or berries - it is very nice as a filter.

    dfk41 “Does anyone have anything to add that I can learn further from please?”

    You seem to have made quite a few brews now. But, it’s difficult for us to see what is going on, in terms of a progression, without knowing the grind setting for each brew, the time that you see dry bed and the weight of the coffee brewed. Also, for each brew, how much you liked it with a simple score (maybe a comment on what you feel is wrong with the taste based on previous brews).

    You can’t ascertain grind size by comparisons to sea salt, or by vague perceptions of what might be coarse/medium by one person’s perception. You can, however, read the number off the grinder’s adjustment scale.

      dfk41 What’s your average grind size reference mate ? Mine are at 32 (12% 400 Kruve) and 45 (9% 400 Kruve) respectively. 😊

        dfk41 Kruve equals the entrance to the rabbit hole! In other words I have no idea!

        Go by @LMSC Duo settings, I’d err towards the 12%/400Kruve setting (around 32) to start with.

        dfk41 I agree with @MWJB. All you need is a grind reference.

        As he advised you, please start with say 32 on the Duo. Please feel free to adjust the grind reference for one bag until you are happy with it. Once you find a sweet spot around 32 (plus or minus). please stick to it for another 10-12 bags unless that default grind reference falls off consistently. These are what I had learnt from him.

          dfk41 I wouldn’t ‘focus’ on any particular note, just be open minded & score on how much you like it. I assume your score of 6 is out of 10?

          You have a weight of 201, this is the beverage in the cup? Seems low for brew water weight of around of 300g, based on this, my guess is that you are under-extracting.

          For example, I have a Melitta Aromaboy, I lose 2.4x the dose weight to the grounds, so for 301g in I get 253g out, plus or minus a gram. You seem to be losing 5x the dose weight…which isn’t possible.

            MWJB Right Mark. I have to devise a routine for the new method. Unfortunately, I have to follow procedure as my brain does not function properly, hence the basic questions. This morning, everything went wrong. because I measured the water out then my wife called me, I forgot to put the water in the machine. It did not switch on! I changed the fuse, then realised my mistake! I will collect a few more brews of data before I post again. I will check the weight of the water before I put it in! but, the main thing is I have got the basic data collection right

              dfk41 You could also record the point where the machine spits/flollops loudly when the last water is dispensed?

              You may as well post, brew by brew, easier to check consistency & track any changes.

              Question from a pedant - Dry bed is 3min 50s, rather than three and a half minutes?

                Round 2…wush wush, 20 gms, tightened the grind up 5 points on the Duo to27. Stopped taking water in at 3.10. Dry bed at 4.09 with an output weight of 254. taste score, 6.5…….once cooled slightly, the aftertaste (not every time) gave the merest subtle hint of citrus, although whether lemon, lime, orange or grapefruit I know not! This is the bed

                  dfk41 So how much water went in?

                  32 down to 27 sounds like a large change in grind size.

                  Was there any silty/powdery mouthfeel in the brew?

                  Was the coffee just flat/muddled/dull, or was it tangy & unripe (like green tree bark/unripe fruit)?

                  dfk41 You will feel it on the tongue before you see any silt in the cup, you may see some filmy reside on the surface of the brew, before you stir it. All coffee has a little undissolved solids in it. If grinding too fine, the small particles coat the tongue & make it hard to pick out flavours.

                  Generally, I’d say brew as coarse as you can before cups become weak & tangy, like unripe fruit. Maybe try the next cup at 29/30?

                    MWJB If @dfk41 is brewing Darkwoods’ Wush Wush, may be, it is worth brewing at 60g/L. I find this 60g/l is a little better in taste than 67g/l at 12% for me.
