    How does this extraction look?

    Do you see any problems with this extraction?

    Looks good to me...
    More important though, is how did it taste?

    Overall looks pretty good. It might be the camera angle, but it looks like it's flowing slightly faster out of the side basket closer to the machine. If so it suggests that distribution could be improved. 27s total shot time is on the shorter end but if it's a darker roast they tend to do better with shorter shot times. If you have tried it I would suggest trying a few shots at 29s and a few at 31s just to see how they compare and what you prefer.

    Good observation! Yes I noticed it wasn't dropping from direct center of the basket so I will try to tamp a bit better next time.

    It is running slightly faster than I would like but grinding it finer seems to make it taste slightly on the bitter side.

    You've just answered your own problem, you need a better grinder. You can only get so far with a Breville.

    It always helps to get a second opinion to find anything I've missed

    I agree about the grinder, but I'll need to save up for an upgrade.

    It may or may not be your tamping causing the flow imbalance. Yes perfectly evenly distributed and flat ground coffee that is tamped unevenly will produce uneven flow, but by the same token unevenly distributed ground coffee that is tamped perfectly well also produce uneven flow. Uneven can mean clumped, more densely packed on one side than the other even when flat prior to tamping, etc.

    If grinding finer brings bitter flavours it can mean it's causing channelling. Increased distribution may be required. I have a BCG820 (unused these days) and at espresso settings it clumps quite a bit. If you grind into the container and then break up the clumps you should have better results. Alternatively add a dosing funnel to the portafilter / basket after grinding and then use a toothpick to break up clumps prior to tamping.

    thank you for your detailed suggestion!
    I will definitely try it out!

    Unevenness can also be because the machine itself is uneven due to the surface it sits on or a similar reason. Sticking a spirit level on it to confirm may be worthwhile.
