  • Fatal Overdose

    I guess every machine is different - I wouldnt know as I have only used my Perfetta - but I find dose is everything and on the occasions that I slightly overdose I can guarantee problems with the pour.
    I slightly overdosed the double basket this morning and got serious channelling with only one of the spouts delivering anything. I think that when I overdose I tend to tamp a bit firmer to try to create the required amount of clearance at the top, instead of just unloading the basket and reducing the quantity slightly. The combination of slight overdose and firmer tamp is fatal. Anyone else notice this?

    If I find that the dose is more than required for the correct level I generally unload the whole basket back into the doser and redose to the right dosage for the correct tamp level. Yes, I find overdosing and tamping harder to get to the right level will effect the shot. I think there is some allowance if its just a slightly harder tamp but if its a significant more pressure on tamping to get the right level it will generally cause some issues.

    Did you try my rice test method for tamp level? Curious how it compares to your current tamp level.

      Thanks for the helpful suggestion saoye. That is a clever method!
      I need to be more disciplined and just unload the basket when there is slightly too much grind. The difference between just right and too much is so small that the temptation is to just squeeze it in a bit more - which is fatal.

        As an alternative to emptying the basket back into the dosing chamber and starting again I sometimes sweep the excess grind out of the basket with a slight scooping motion with my finger (as opposed to a level sweep) so as to compensate for the excess grind - works particularly well when youre busy making a lot of coffees - or if the coffee is being temperamental and your minor adjustments to the grind settings are yet to have the desired effect...
