Distribution tool path

I've been experimenting with different patterns of moving the grinds with the distribution tool, but I've yet to settle on one. If I swirl it about the edges, I end up with a hole in the centre; but if I swirl closer to the centre, I end up with walls of coffee rising over the edges of the basket on one side or another. On the other hand, if I just trace out random patterns, I get random results. What do others do?

  • I do a random stir, a brief shake, one tap with the pf on the counter, mild press with the flat tamper, lock in and go.
  • I do the same as Frans and results are so much better than without the tool. I add the ring to the portafilter, grind on demand and stir. Love how the ring prevents most mess. I almost always get a good looking naked shot.

  • Thank you for that fascinating account, Frans. My puck preparation is a little different. I grind into a small flask and weigh the grinds in the flask, having previously tared the flask. I usually aim for 15g in a 15g VST basket, although I lower the dose for dark roasts. My go-to brew ratio is 30g liquid out for milk drinks and 32 for plain espresso. I see you prefer more ristretto ratios.
    I next pour the grounds into the basket, employing an OE dosing ring, through which I WDT. Then, if needed, I level the grounds roughly with the edge of a palette knife, rather than tapping the basket. Finally,I give the surface a quick spin with an OCD distribution tool and drop the prepared basket into a bottomless pf.
    I have a pre-R Londinium 1, and I find that with lighter roasts I have to wait too long for drops, so I just release the lever after 10" pre-infusion. That usually results in the lever catching at 45 degrees and a picture-perfect pour. I aim for a flow rate of roughly 1g per second.
