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

    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.

    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.

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

    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 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!

    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.

    In the end a compromise could not be reached  
    There must be more to it as I dont see that there needed to be a compromise from waht Ive read.

    The boss agrees the coffee had a problem.
    The tech says you make the best coffee.
    The franchise head said the same.

    Theres no compromise needed.  The franchise head should have told your boss that you were right and that hed go tell all the other franchises to do the same.

    Id have left to.
    Sorry you had to.
    The compromise was that the boss wanted the coffee gushing out in 12 seconds again. :P

    why not just change the grind when he is not watching and put it back when you get off the machine?

    but yeah sometimes your just better off leaving...... it can be hard working for idiots and just not worth it whatever they are paying

    So technically, thats even worse than tapping on the dosing chamber

    i agree the lever force would higher and  more damaging IMO.

    i sometimes put mine there to sweep (on doser) if making multiple shots but why not just tap on your mat or bench?

    As much as I understand the sentiment, its hard to follow this when the boss wont let you adjust the grind.
    So let me understand.
    a) The boss wont let you adjust the grind - check
    b) The boss says dont tap on the dosing chamber edge - check

    a) is easy - do nothing
    b) Do it - get caught - get another kick up the @r$e because youve been told before

    See Rule Number 1: The boss is always right.

    I was told by a very well known, highly credentialed, award winning barista that even they had to compromise on their standards when working for someone.

    You might know better and I might agree with you but in the end you either do what youre told by the person that pays you or else go find another job.
    Just that one for me mate, the tapping on the grinder isnt my issue.

    As it stands, I want to serve the best coffee possible for my customers. If that means that I butt heads with the boss, then so be it.

    In the above instance I did leave because a comprimise couldnt be reached. When I arrived the coffee was flowing out in about 12 seconds, including pre-infusion.

    I adjusted it to a nice 25-28 second flow, and got lots of compliments from customers. The boss was a franchisee for a small Melbourne based cafe chain, so he didnt really know coffee.

    He insisted there was a problem with the coffee, had the roasters tech come out, check the grinder, said I made the best espresso using their beans that he had tasted, boss still not accepting it.

    Had the head of the cafe chain come out, said the same thing. In the end a compromise could not be reached so I left rather than have the stress.

    Just watched an instructional video on the ECA website and noticed World Barista Champion Scott Callaghan doing exactly this

    http://www.espressocompany.com.au/grinding-dosing-video.htm

    NO...he doesnt.

    He taps the group handle on the built in tamper mount of the grinder, NOT the edge of the dosing chamber.

    Completely different kettle of fish; not that Id recommend this either as I doubt the mounting point was designed for the punishment hes giving it.  
    Not really a different kettle of fish - the built in tamper mount connects to the dosing chamber. So by tamping on the tamper mount, you increase the moment arm and thus the force exerted on any bolts that hold the dosing chamber on. So technically, thats even worse than tapping on the dosing chamber

    Can we damage them with such a method eventually?
    Id say so.
    I dont do it to mine.
    Find something else to tap on.

    Rule Number 2: When the boss is wrong refer to Rule Number 1.

    Ya, know a few like that.... Their contract and or service agreements may imply that other than teh service people... No touch :-?

    Then the are the others that think they know better... And besides if teh customers dont complain... The it must be OK :

    Ya need to come up with a method, where they make the decision that it needs to be adjusted...

    Ie. Every one starts complaining after xxx and it gets worse as the day get on... Must be temp and the beans sweating... Toss out and replace beans or change teh grind setting... What do ya recon ?


    But by the same token... Has a barista in a top hotel complaining that he was not allowed to make changes etc... Then when I asked for a long black... Just hit the button twice/three times...

    So...

    Rule Number 1: The boss is always right.
    Rule Number 2: When the boss is wrong refer to Rule Number 1.
    Rule Number 3: When the boss is wrong get him to think differently and then refer to Rule Number 1.
