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.

Re: Just purchased an Isomac Venus
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...Originally posted by 76603C733C783C627B717977607B7C75120 link=1244684389/18#18 date=1314364303I dont understand terntski commentsOriginally posted by 756060717C343432050 link=1244684389/9#9 date=1314266783dose to full, tap pf, dose to over full, tap pf, tamp light
I assume you talking about settling/collapsing which merely allows more coffee in the PF and allows for volume dosing using a sweeping technique
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

Re: Just purchased an Isomac Venus
I really dont understand what you are trying to convey.Originally posted by 3036212A30372F2D440 link=1244684389/15#15 date=1314333894So 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?
To what type of tapping are YOU referring?
Tapping during settling? OR tapping TO settle,Originally posted by 3036212A30372F2D440 link=1244684389/15#15 date=1314333894tapping during settling
theres a bit of a difference.
I dont know a method of settling which does not involve tapping the portafilter.

Nope, no misunderstanding here 8-)Originally posted by 414A52584445474E445C2B0 link=1244684389/13#13 date=1314327554Trentski, I think you misunderstand.
Nobody? are you sureOriginally posted by 414A52584445474E445C2B0 link=1244684389/13#13 date=1314327554Nobody is tapping the portafilter during the tamping process.
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.Originally posted by 414A52584445474E445C2B0 link=1244684389/13#13 date=1314327554Its just a settling the coffee grounds, perhaps up dosing?

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

Re: Just purchased an Isomac Venus
I thought the tapping that fractured pucks came after the tamp, the tapping be refereed to above is just settling isnt it?Originally posted by 4D4B5C574D4A5250390 link=1244684389/10#10 date=1314267788Had 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.

Re: Just purchased an Isomac Venus
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.

Re: Just purchased an Isomac Venus
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...Originally posted by 784F5656534E4E3A0 link=1244684389/5#5 date=1313457075Suggest 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.Originally posted by 4E5B5B4A470F0F093E0 link=1244684389/4#4 date=1313217757Well i pulled back the pressure valve.. Now can use a coarser grind, getting better creme, but still get wet pucks...
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...?
