    Bottomless porta-filter issues

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Happy Easter. I recently acquired one of these gadgets to play with over Easter as I am sure it will help with my tampering technique and shot pull. Did the usual this morning and while it starts off with a centre column/funnel as it should [and I begin to glow inside], it then starts to squirt the shot all over the place with some still filling the centre. Have had this happen three times now and checked to make sure I have the handle in nice and tight and also the basket in square.

    Is this normal, suggestions for a fix? It makes a mess *
    Thanks

    Hello Purfect. This phenomenon is called chanelling and can be caused by imperfect distribution or underdose...

    There is plenty within the forum to be found with a search.

    Good luck ;)

    Some anti-chanelling techniques to search for are nutating tamps and (particularly for Ms Silvia) pre-infusion of the manual variety. *Assuming you have your grind & distribution well sorted in the first place.

    Thanks for the tips. The grind and distribution , while not perfect, doesnt appear too bad, and up-dosing sorted the squirts. I got the bottomless handle to assist with trying to fathom out why I cannot get the grind, and whatever else, to slow down the flux of coffee.
    I never had these issues on my el cheapo machine and despite 6 months of playing, reading the board forums etc, the flux remains fast and switches from chocolate to caramel very quickly.
    Coffee tastes fine but always room for improvement, so will follow up on those tips as well ..thanks

    Brew pressure too high?

    More importantly, does it taste bad?

    Cheers,
