    Re: Just purchased an Isomac Venus

    stay calm ;D

    Tapping after tamping is said to fracture the puck or dislodge it from the side of the basket, tapping during dosing as a settling technique may not be without its downside as well.

    You want to be consistent with your technique, its pretty hard to "tap" consistently so why not take it out of your process? What do you think it is adding to the taste in the cup? could it be detracting from the taste in the cup?

    Are you simply tapping because Scottie Callaghan does it?

    I grind, rotating the group handle as the basket fills, level off to a small mound (similar to stockfleth manoeuvre) and use a light tamp. Naked handle shows an even extraction with no channelling and its very repeatable.

    dose to full, tap pf, dose to over full, tap pf, tamp light
    I dont understand terntski comments

    I assume you talking about settling/collapsing which merely allows more coffee in the PF and allows for volume dosing using a sweeping technique
    Yes, i think there is confusion because i am using a doserless grinder.. The coffee doesnt have a chance to settle/compact before it is dosed into the group... i think...

    Anywho i am getting heaps better results now, and no wet pucks!

    This the technique Scottie Callaghan discribes
    1. Grinder on
    2. Pull group handle out of group head
    3. Knock coffee out in knock box
    4. Clean/wipe out filter basket
    5. Grinder off
    6. Put group handle on grinder forks
    7. Pull dosing chamber lever 4 times
    8. Collapse on grinder forks twice
    9. Pull dosing chamber lever another four times
    10. Collapse on grinder forks twice
    11. Pull dosing chamber lever four times
    12. Collapse on top of grinder (given you are working on a grinder that has a metal casing for the dosing chamber) four times
    13. Sweep

    So the question, which should be for another thread, remains. What are you hoping to gain by tapping during dosing and is it making a positive contribution in the cup or are you doing it because youve seen others doing it?
    I really dont understand what you are trying to convey.
    To what type of tapping are YOU referring?

    tapping during settling
    Tapping during settling? OR tapping TO settle,
    theres a bit of a difference.
    I dont know a method of settling which does not involve tapping the portafilter.

    Trentski, I think you misunderstand.
    Nope, no misunderstanding here 8-)

    Nobody is tapping the portafilter during the tamping process.
    Nobody? are you sure

    Its just a settling the coffee grounds, perhaps up dosing?
    There is discussion around the webs that tapping during settling has no effect, a negative effect, a positive effect, depending on who you listen to.

    So the question, which should be for another thread, remains. What are you hoping to gain by tapping during dosing and is it making a positive contribution in the cup or are you doing it because youve seen others doing it?

    Re: Just purchased an Isomac Venus

    I guess the question to ask is, why are you tapping the group handle, what are you hoping to achieve?

    Can you see any difference in the cup between tapping and not tapping?

    Probably a subject of its own although I am sure it has been discussed a number of times already. FWIW I dont tap

    Had another play, think i got it about right, grinder set to 14, dose to full, tap pf, dose to over full, tap pf, tamp light, theres only about 3mm of gap between top of filter basket and coffee. Great shots, no more wet pucks


    Be careful with that tapping, you may find that it fractures the puck which leads to channelling.
    I thought the tapping that fractured pucks came after the tamp, the tapping be refereed to above is just settling isnt it?

    Yea, its hard to dose consitently without a doeser system.

    And your right, if it tastes good, i shouldnt be worried about it.

    The Smart Grinder is on my list of things to buy, i can only imagine it will make it easier to fine tune my tamp... Had a pretty expensive month so far, car tyres, rego, ctp... Insurance due next month! eek! Grinder will have to wait

    Re: Just purchased an Isomac Venus

    If you are taking the pf out straight after pulling a shot the puck may seem a bit sloppy with surface water but this is normal and I dont think it is a real problem. A sloppy puck is usually from grinding too fine or underdose like mentioned.

    If it tastes good I wouldnt get overly concerned about the puck.

    Chances are with the grinder you are using you are expecting to much. I had the em0480 and went to the Smart Grinder and its a massive improvement in shot consistency.

    Well i pulled back the pressure valve.. Now can use a coarser grind, getting better creme, but still get wet pucks...
    Suggest yo try and dose a bit more into the basket, sloppy pucks can be due to low dose.  If you not already doing it, tapping the PF on the bench to settle grinds into the basket is good way to get a bit more in with some repeatability.
    Yep, already doing that, getting better now, read up on some other forums that wet puck are a problem with the Venus, though not sure...

    Last night i was practicing with different tamps and found softer tamps better for puck dryness. Also realised the tamper i have been using for years is concave That could also explain some things too! How much of that would make a difference...?
