    Gosh, I think I'd give up home espresso if I had to spend 5 minutes preparing my dry dose every day. Timed grinder is the bomb. Forget about retention and scraping and clumps and... Just purge a little and enjoy your morning cuppa.
    Otherwise buy a hand grinder with little retention. Same effort, less money, and you're using it how it's designed.


    [Edit - I make on average 4 coffees per day in our household. Single dosing was something I did maybe for my first month of making coffee, and it got: 1. very tiresome, 2. inconsistent (you might think that is counterintuitive). There's no way I'd single dose 4 espressos when having 100g+ in my hopper gives me more consistent grinds and saves me time. If all you're drinking is one espresso a day, sure, but much more than that I'd say stop single dosing, take the plunge and actually use your hopper.]

      I am hoping something like Macap M4D will provide more fine grind levels for espresso compared to Rocky but the grounds retention inside the grinder seems to be a problem.
      - I use my naked portafilter 90% of the time
      - Tamp I got from Coffee Parts in their startup pack thingy
      - 20g VST basket (fits 21-22g easy)
      - Hario scales/timer (.01g)

      I find my problem is matching the right grind time to the correct tamp weight. I do try to keep them as regular as possible but it's frustratingly easy to screw it up a little but have large errors as a result.

        It's the 98mm group handle you need to keep the EK43 balanced that concerns me.

        Maybe put the scales away for a while and develop the art of coffee making rather than following a scientific process.

        I almost always pulled good shots on my Rancilio Lucy and never weighed anything.

          I'm surprised you have to ask this question, after reading your last post it's obvious you are quite knowledgeable about things espresso.
          thanks for your vote of confidence! 8^)

          re burrs - I have never replaced them, how often do I need to do this and where do I do this (I live in Melbourne) ?

          if I make say ~15 double-shots per week on average, how many weeks of grinding will Rocky burrs last, approx?
          I bought Rocky in middle of 2010, so this makes it ~300 weeks old, so 300*15 double-shot grinds done on existing burrs.

          thanks!

            I see your point but it does not take 5 min to weigh the beans and grind them using Rocky.

              My Synesso ridgeless double fits 20 grams comfortably and maxes out on 21 grams, so 1 gram smaller than your VST, I guess.
              Using 1 gr of beans for 2.5 ml/grams of espresso extraction rule you should aim for ~45-50 ml/grams double shot in 30-35 seconds, in my opinion.
              Every time I had < 30 sec extraction for 45 ml double shot was not memorable, not in Silvia and not in Gaggia Classic that I owned for 6 years prior to Silvia.

              Slower extraction seems to be better, up to a point. If I get to >45 seconds extraction for 40-45ml then I usually throw it out and do it again.
              Many YouTube barista videos I have seen that show you how to make great espresso are a bit too fast for my taste.

                Well and truly time for new burrs, in fact I suspect overdue.

                You can do the job yourself if your a bit handy, buy genuine Rancilio burrs not aftermarket stuff, or I'm sure Chris from Talk Coffee could do the job for you. Talk Coffee | Professional Coffee Machines

                  No value whatsoever and in fact completely counterintuitive to pay $$$ for an accurate digital timer if you have no intention of using it...

                  It's also 100% clear that that the answer must therefore be EK43
                  pardon my lack of knowledge, what is EK43?

                    thanks! That should be much cheaper than spending $1000 on Macap M4D 8^) LOL

                      It certainly should be, a new set of burrs approx $60.

                        I dare you to time it from the point you grab your bag of beans to the point that you've finished tamping. 5 minutes might have been facetious, but I'd posit you're up there in the 2-to-3 minute mark after you've swept out and found your .01g dose. My timed grinder (Profitec T64) gets me my dose in 7 seconds. So, I have my prepared puck at about 15 seconds, before you've plucked out that one extra stray bean.

                        I know it's not all about speed - for some the enjoyment of preparing espresso is more on the preparing side than the drinking side, each to their own. But there is definitely a law of diminishing returns at play here, and you'd surprise yourself at how much you wouldn't lose by timed grinding from a semi-filled hopper.

                        So - get a timed grinder, and enjoy it. OR change your burrs, and enjoy how you're currently preparing your espresso

                          Why do threads of this nature always seem to turn into a p*ssing contest, must be a gonad thing (my method is better than yours)

                            Really? New burrs after grinding 300 double shots? Seems a little bit of overkill to me.

                              'Cause people ask about timed grinders AND single dosing in the same question...

                                4500 double shots.
