    Re: Tapping the group handle on the front end of the dosing chamber.

    Strictly with regard to the title of this topic.

    Do not do this.  It damages the equipment...the equipment earns income. The grinder usually doesnt even belong to the cafe it belongs to the coffee supplier. Why damage equipment that earns income and doesnt belong to the cafe?

    In mild case scenario, it chips out the rim of the perspex and eventually, or in the worst case scenario, cracks up or breaks the perspex.

    According to Murphys Law, this always happens at the worst possible time.

    Someone with a proper command of technique and with a healthy respect for the equipment and their business wouldnt damage it.

      I dont think its a very good idea to rap the pf on the dosing chamber. It damages the portafilter and adds really ugly lines on the bottom of it.

      If you want to collapse, do it on the pf forks!

        We just use a tamping mat. You can actually tap pretty hard as you have the firm rubber mat and there is no damage to anything!

          I agree with Wushoes, use the group handle forks if you have to tap. :P

            Im not a professional barista but Id tend to agree with Cremachine - why not use a tamping mat? Even tapping on the forks is still metal banging against metal. Id never do that with my own equipment nor anyone elses.

              Hi all,

              if you do it anywhere on the grinder it will eventually get damaged or break...somewhere.

              The best place to tap is on the edge of the bench. That way you tap the bottom of the group handle, NOT the spouts which also eventually break off when you use them as "tappers".

              You can now buy tamping mats that have a right angled bend in them so they fit on the edge of the bench and go down the edge. That way you wont damage your granite benches.

              Do not tap the spouts on the tamping mat. The tamping mat always has spilled grinds on it, the spouts are wet when in continuous cafe use, so they pick up grinds and then drop them into the cup during brewing.

              For final tamping after you have settled the grinds by "tapping", you can now buy a raised tamping jigger that the group handle slots into. It keeps the spouts OFF the grinds which live on the tamping mat.

              These barista aids are not expensive and help to better your system of operation and technique.
              Hope that helps.
