Good People,
I am the owner of the two pieces of machinery in the header and am having some difficulty. Up until today - and after trawling through the boards here - I have used the pressurised porta filter that came with the machine. I ordered a non pressurised PF and it arrived today and I have just spent close on the last 90 minutes pouring shots down the sink.
Some salient facts:
The beans are fresh (Merlo Private Blend)
The machine is clean
I am tamping (I have done a Barista course but rate my skills at novice level)
The grind is set at 2.5 on the 2002 grinder
My problem is I just cant seem to get any consistency in the shot - one pull will give me about 30 mls in 20 odd seconds, the next will burn because it takes so long. I realise that this is probably due to my tamping consistency (all other things being equal) but I am really frustrated particularly when it feels like I am applying the same amount of pressure each tamp.
My questions then:
How long should it take to get 30mls from my machine - on the course I attended, the trainer suggested that it would be about 20 seconds but I am not sure if he was referring to the PPF or non PPF version? :-?
Has anyone any experience using the single basket - it is producing an even worse result than using the double? :-[
Is it my lack of practice that is giving me the grief or is it partly the machines fault?
Any assistance would be greatly appreciated, I have gone from producing a passable shot to something the I cannot drink. I got so frustrated that to avoid throwing the thing across the room I made a cup of tea using the kettle....
