My rule is that if there is 12g or more left over I will make a ‘random blend’ by making it to 18g with beans from an airtight container I keep in the freezer which houses beans from those bags which has less than 12g left in. My thinking is that if it’s more than two thirds it will be close enough to avoid re-dialling in. Most of the time you get a tasty shot. Occasionally it pulls weird and it’s a sink shot, but at least I’ve tried to utilise the leftover beans.

JimmyP Yes, I have posted about this before.

For brewed 12.5 to 12.9g suits most common bag sizes.

14g +/-3g.

16.2 to 16.9g.

17.5 to 18.1g is good for most bag sizes except 150g

20.6 +/- 0.6g.

I often find that bags have 2-4g over in bean weight, though typically I don’t weigh the bag until a fair way through.

These are whole bean weights, you need to allow for whatever dose consistency your grinder has.

    JimmyP For instance dropping from 18g to 17.9g for an extra shot of espresso! 😋 (250g)

    Your calculator needs new batteries.

    14×0.1g = 1.4g, not 17.9, nor 18g.

      I stick to 19.5g now or 20g decaf both using thick puck screen in a deep acs basket.

      As per @axpetts i enjoy one, never to be repeated blend as I use up the last X.Yg from the end of a bag and top it up with my new bag.

      I assume there’s a slight rounding error in the 17.9, it would need to be 17.857g (or 17.9 if your scales are only one decimal place). But I think the point is that dropping 0.1g doesn’t save a whole 18g shot but means you don’t have a half shot worth of beans left at the end.

        Im doing something wrong

        Cant believe what im reading

        Its getting, putting it politely, Daft to the nth degree!!

        Do you guts swap out beans when weighing to get to the exact .000 or . 500g every shot

        And who can honestly tell the difference.

        Im more than happy at plus or minus just over .1g and am most likely not that accurate most days.

        I do not think anyone in a blind test could pick out plus or minus 0.2g. maybe i belong on face book, not here 🤪☕

        Thanks for all the fish!

            Consistency will be vastly improved.

            James and Lance (who work at the local hifi shop) said its definately true so it must be .

            For the sake if clarity i am taking the piss here !!

              Just forget about that cheap as chips 10 -30 metres of grey twin and earth mains cable in the wall at 36p per metre supplying that final metre. These HiFi shops should not be allowed to make the claims they do.

              The reviews are truly laughable as are the terms they use for the music: Separation between notes, leaner, soundstage, neutral, detail , better defined. *“Audio is cleaner the noise floor is much lower, separation of instruments is better smaller previously unheard details are now heard and the system becomes much more musical.”
              *
              Apparently these are half the usual price for such cables.

              Do a large number of people really believe this garbage and the fake reviews that accompany it and the Hifi Choice 5* rating???

              And, more importantly, are we the same with coffee, as some influencers would have us believe?

                Dusk Start by measuring the coffee you actually have in the bag. Divide by your dose weight, then round up to make the number of whole doses fit.

                14dosesx18g= 252g, you’ll more than likely have that in a 250g bag.

                You can’t practically weigh beans to 0.10g dead because whole beans weigh more than that.

                Your final doses will vary by what your grinder holds back and by cumulative inaccuracies in the scales, but these won’t matter much in term of actual consistency/drink quality.

                Adrianmsmith Do you guts swap out beans when weighing to get to the exact .000 or . 500g every shot

                You did just say, “stick to 19.5g (which is 19.500g) now or 20g (which is 20.000g) decaf”. I found that odd, but you’re free to do what you want and share in good faith

                Adrianmsmith And who can honestly tell the difference.

                When you dose 14g per drink and have, say, 7g left in the bag, most people would tell the difference. I also often buy small bags of expensive coffee, where it tends to matter more.

                  They really must do!!

                  Sorry if it came across that i was being serious. 😎🤭

                  I guess the use if the work “may” occasionally keeps these claims legal if not immoral!

                  I also ordered some snake oil to make my surgery scars heal quicker!!!

                  Why odd do you make shots with both?

                  Being genuine here, not taking the piss, nothing to do with snake oil, the decaf we are using from rave and coffeelink definately needs more in the basket to dial in and give similar head space then the standard coffee i like.

                  I do not tend to buy what you describe as expensive coffee. I just stick to outlets such as rave, black cat, coffeelink, origine, extract etc etc.

                  Whilst my target is 19.5g or 20g im not looking for 19.500!

                  Plus or minus .1 ish will do fine, or should that be finer!!

                    I understand that some decafs are less intense than others, but you can also adjust grind size & ratio. Which is probably the route I would take, but do what works for you.

                    What is odd to me, is most common bag sizes don’t divide by those dose weights. Adjusting dose weights slightly to reduce wastage will make likely no difference to shot quality, just to wastage per bag. Again, if you like a home made blend at the end of the bag, all power to you. I might make a French press, or a Cesve in the same circumstances, if left with an odd dose amount.

                    No one measures to the milligram, but you can stick as many noughts as you like after 19.5…it’s still 19.5 when rounded to one decimal place. You weigh to +/- 0.1g. That’s great, but whether that ends in a 0, 5, 3, or 7 isn’t any more/less precise/pedantic/more or less difficult. It’s the same tolerance and that’s the target in my post above.

                      dfk41 I agree…and it definitely won’t if you make up half the dose with a different coffee (that’s what we’re discussing, not how much difference you need to force a recogniseable fault).

                        Its to do with headspace and how i like my puck to not be sloppy.

                        Generally speaking, does decaf needs to be pulled longer or shorter?

                          Inspector

                          I dont actually drink it, but, i try and keep comments from my Wife on the good side!! She has it as americano not a straight shot.

                          Best comments seem to be circa 5 seconds pre infusion and 30 35 seconds shot time.

                          One observation from me is that decaf always looks like its going to run quick but somehow slows during the main shot.
