    Greg could you - or anyone else - describe more about this negative effect?  One or two taps to settle the grounds evenly is okay, but more affects the flavour negatively?
    Thats how it works for me, with my machines, methods and taste buds. When I tapped 3 or 4 times to settle the grounds, the volume in the basket was less and the extraction time changed and the flavour of the extraction was worse--to me.

    Try it yourself and see how you go. Coffee is so individual that what works for you, works for you.

    Okay, this is a new concept for me as I read this thread: tapping. I havent thought about it or what effect it would have on the shot. Mostly because Ive had a dreadful grinder up until last night.

    Greg could you - or anyone else - describe more about this negative effect? One or two taps to settle the grounds evenly is okay, but more affects the flavour negatively?

    Thanks!

    I have found that too many taps (more than 2 for me) always has a drastic negative effect on the coffee. I think it settles the grounds rather than packing them the way a good tamp does.

    I just tried some of beanbays Colombian Volcan Galeras on the weekend. It was a little fast, but I tried a couple of different things:
    • only one light tap in the "grind, tap, grind"
    • a more symmetrical sweep
    • no polish.
    Not sure if its that or the beans, but holy moly the the crema was thick! It came out in a wide stream from almost start to finish. I also noticed that it tamped lower - probably because I didnt tap so much that there was less coffee in there.

    It was a little fast, but otherwise tased much better. I think this one is lower in acidity than the Tanzanian which probably suits me a bit better.

    just replaced my gauge and it is at a perfect pressure of 1.1. There goes my "too cold" theory. Im still getting some chanelling, so Im experimenting with no tapping, no polishing, etc. Could the thermosyphon be blocked?

    I have to say, compared to the Giotto, my Lelit combi is so much more forgiving. I just pulled a shot with a double basket on the Lelit which I would probably call a gusher (about 70ml in 25 seconds) and being used to the Giotto was expecting a sour coffee but not at all. It was a very pleasant espresso. I know the Lelit is no where as hot as the Giottos E61 grouphead, but then again that to me would mean a greater possibility of under-extraction and therefore sourness. Its really strange to me why the Lelit is so much easier to pull an all round good espresso compared to the more fussy Giotto. But then again I find the shots out of the Giotto much prettier. I definitely enjoy making a coffee more using the Giotto, but find I have to have much more skills to get it tasting as good as it looks. I just hate a sour coffee! >

    So at work I drink a double espresso from the Lelit and at home lattes from the Giotto...unless I know I got an almost perfect shot. I am using a single basket on the Giotto though, so maybe I am a sucker for punishement.

    but any finer and its sloppy.  Even on this one it was "wet" on top which drained before I took the photo... It doesnt look coarse when I grind - could the grinder be a bit inconsistent?
    Hmmmmm
    I noticed that you measured straight into the hopper (which I did for a long time too).
    I have heard it said that this can cause some grind inconsistency, as the first half of the grind has the bottom beans weighted down evenly by the top ones, but as the number of beans decreases the later grind gets coarser, even pop-corning at the end (bouncing off the burrs into the air etc as there is nothing pushing on them).
    I personally never noticed a huge difference - but having a doser might have helped to mix it all up a bit - but straight out of the shoot in the K3 this might make the top layer in the PF coarser than the bottom - creating your pooling when you go finer? The bottom is too fine while the top is too coarse?
    Have a try at keeping the hopper 1/4 - 1/2 full to keep an even bean pressure throughout the grind and see if this gives you a more even result. That way youll know that the grind is consistent throughout the puck.
    I keep the hopper 1/3 full always now - esp with home roasted beans. Even after 10 days the beans seem to improve with some resting time out of the bag - and the added advantage with this system is that our whole house now smells amazing

    I notice with the K3T the top burr seems to be able to move if I touch the hopper - could this be causing the blades to not meet parallel and make some inconsistent grinds? Just a guess...

    Hmm, doesnt look bad at all.
    I agree. Looks like a nice puck Anything seriously wrong itd look like a train smash…
    But even from that pic (and the pour in the vid) the grind still looks a bit coarse… Id fine up a fraction too and hit it again.

    Hmm, doesnt look bad at all. the large circle I suspect was the top of the grind stayed behind stuck onto the shower screen as you removed the portafilter, I dont think thats channeling.

    So maybe its just a matter of a slightly finer grind adjustment since you say it was on the sour side?

    did the puck show any holes? again how did it taste?
    Ive attached a picture I took just after that shot, and circled some suspicious areas - not sure why they look like that.

    It was a bit sour, but not disgusting.

    Nice to meet a local snobber! Is that a manual lever and smart grinder you have there?  Do you taste your shots "black"? How would you describe it?  Id like to take you up on that - lets meet sometime.  I may have some free time next weekend - 17th or so.  Would this be the first ever NT meet n greet?!
    Correct on both the grinder and lever (although it is a spring lever).
    I should be free around then, although it is the works Christmas party the night before so maybe not very early.
    Just about to start roasting again, but not got my corretto set up properly yet. What beans have you got? I will try to order something different to taste (and not from anyone local).

    Glad to have a new member to coffee vids annonymous

    nice vid. I noted it started slow and then the streams thickened with a few glubs if thats the word...could be channeling. did the puck show any holes? again how did it taste?

    Re: What am I tasting in my espresso?

    thanks although its squished in sideways for some reason - even though I told it to fill out, I think my camera uses widescreen pixels and youtube likes 1:1 pixels... I thought Vegas would fix that, but maybe I forgot to check the option.

    You cant see the grind into the pf, nor the dose / sweep - Ill move the camera next time.

    This was my first go after backing off the grinder a bit (you can see that at the very start) so I was guessing with the tamp, but it seemed to work ok. It is usually a tad slower. It tasted maybe a touch sour, or acidic, not sure which.
