    Re: pulling a shot problem

    Hi tal,

    There are 2 possibilities that I can think of.
    1 - your tamp is not quite right. If the tamp is uneven, or the coffee distribution is not right before tamping, you can get what is called channeling which can, in turn, put more liquid to one spout than the other.

    2 - your PF spout might need a clean. Sometimes coffee oils and gunk can build up in the spouts and cause flow issues.

    Hope that helps.

    Brett.

    Re: pulling a shot problem

    Greetings talbashan.

    This is a common "problem". Most commercial machines these days have a little "vane" in the outlet spout of their double group handles, which can be turned while coffee is pouring, to result in an even flow to each side.

    Probelm is, no sooner have you adjusted the thing than it goes out again!!!!!

    Probably something to do with the direction of spin of water gping down the plug hole in the southern hemishpere, and Ill bet it goes the other way in the northern hemisphere!

    Once you have made sure there is no obstruction in the exit hole of your group handle, and tamped evenly, if it keeps happening there is little you can do Im afraid (excpoet maybe to see if a commercial style spout with adjusting vane will fit on the bottom of your group handle).

    regardz,
    FC

    Re: pulling a shot problem

    have you checked if the machine is sitting level?

    the way I look at it, the way spouts are designed, youre only going to get uneven pours is if its not level, or if theres something obstructing the path of the espresso.

    sometimes, due to the viscosity of the espresso, it will start pouring on one side, and kind of build up tension on the other side. Ive seen people use a skewer to break the tension, and get the flow going evenly.

    but check if the machine is level. I guess you could sit a spirit level on the drip tray or something.

    Re: pulling a shot problem

    Also if you havent done it lately pull the basket out and soak the portafilter in some backflush solution. A build-up of oils etc in them can lead to uneven flow, not to mention detracting from the taste in the cup!

    Try doing it naked. PF that is. No more spouts, no uneven levels. Pure, unadultered, untouched crema in one cup. No sharing, its mine all mine... ;D

    Re: pulling a shot problem

    hi boris,
    i got a naked PF recently. the only problem with that is that when i use the double filter i get too much coffee.. too strong.
    if i use the single i simply doesnt work. dont ask me why but it doesnt. the single filter is useless, whether i use a naked PF or a normal one.
    any suggestions will be appreciated.

    Re: pulling a shot problem

    Singles are much more sensitive to grind, distribution, leveling and tamping than doubles are. Any flaw or problem in your technique or equipment is magnified when using a single.

    If you really wanted to test a baristas skills youd force them to use a single in competitions rather than a double. :)

    Using the single with your naked PF should allow you to perfect your technique as you can see where/what the problem is more readily than with a double.

    Or like me you can get used to drinking doubles in a cappa cause you think its a shame to waste the coffee :o. Trouble is I got a bit too used to it and found a single shot wasnt enough any more. Now I have discovered the short Macchiato - much better (and I just dump the other half of the shot)!
