    Well last time I had a Barrister for a half-day session it cost me $3,500- and in the recess, Mr White informed me that the half-day rate meant that he would only pay for one Flat White! : true story... Full day rate is therefore $7,000- AND includes two flat whites....

      More important is the beans itself, roast date etc and the correct dose. Tamp does come into play but if they don't have good beans to begin with then it's all minor improvements.

        Oh dear, Ground Hog Day, again.

          I once asked a barrister if he would answer two questions for me for $500 and he said "Certainly. What's the other question."

            But surely with no tamp at all the shot would be severely prone to channeling and consequently very inconsistent. You would have to grind very finely and with 9 bar of water pressure hitting loose grinds, I can't imagine a good shot. Maybe in the example given, the barista is overdosing and effectively using the showerscreen to perform a light tamp?

            BTW, I agree that tamp pressure is an overated factor, with dose and grind being more critical variables.

              One of the Italian entrants in the world barista champs a year or four back did not tamp. Must need a different grind / dosing setup to work, however it must be possible if he could compete at that level.

              Tamp pressure: a 300lb (say 130Kg) single tamp test done by La Marzocco showed no compression below 1/4" of the top of the puck. That is partly why progressive tamping is so important / critical w a naked. Other setups: who knows?

                Am I reading this correctly? You're saying they put a 130kg tamp on a basket and there was no compression beyond the top 1/4" of the puck?

                  No. Not necessarily...It all comes back to grind, dose and distribution. Get them right and tamp becomes far less important.

                  Yes- not a new thing....It all comes back to grind, dose and distribution. Always has...

                  My detector just went off again....

                  Sorry, but bollocks.... It probably helps sell tampers, but it all comes back to grind, dose and distribution. Always has...

                  Get the above right and you can use your palm, the base of a glass or nothing if you wish.

                    This is incorrect, assuming everything else is right a regular tamp with a naked PF is all that is required.
                    Not sure where your getting your information from Tampit, you certainly come up with some oddball idea's.

                      A lot of the stuff you post is (to me) knowledgable, well-thought-out and interesting.

                      The above is pure fiction. A naked PF cannot logically have any effect bar whatever difference in taste you think might be caused by contact with the basin/spouts that exist in a spouted PF but not in a naked.

                      There is not and cannot be any difference in pressure or flow in the system due to choice of naked/spouted PF if the shot is not gushing and the spouts are appropriately sized.

                          Must admit the forum is certainly good for the odd chuckle nowadays.

                            If the 130kg tamp only compressing the top 1/4 were true, it would revolutionise the helmet and many other industries.

                              A bullet will punch through several inches of timber (making a mockery of all those movies showing people being immune to being shot by standing behind a fibro or weatherboard wall) but be stopped cold by a book less thick than the wall. Humour is one thing, but be aware of physics.

                              I'm more interested in how the OP went with his edjumacation of the barista...?

                                Yeah you have me there Journeyman. Certainly no physics or any form of science in that long bow.
