    Question how much adjusting the grind?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi People,

    I work in a bakery that sells coffee.

    our shop assistant/barister decided the reason he could no make drinkable coffee was because of the coffee beans.

    so we changed coffee suppler and now have a super jolly with a grind on demand attachment.

    this was set up by the coffee rep./ barista the coffee seemed excellent.

    The next morning the handle to adjust the grind has been moved about 60 degrees and the coffee again is undrinkable.

    I am not familiar with commercial grinders however the barista from the coffee company was only moving the adjustment a mm or so at a time.

    Is a a sixth of a turn a large adjustment that it seems unlikely to have to make overnight?

    This person seems good at talking (lying) but often struggles to get any results.

    Hi don_nairn,

    I have a super jolly electronic that I use at home, and the most I would adjust at any one time is a mm or two.

    A 60 degree turn is totally out of the ballpark for a grind adjustment IMO.

    Does your barista's brother own a cafe down the road?

    Man, that's quite the adjustment! The actual handle can be unscrewed and out into a different place on the collar so it could just be that..but how's the shot looking? is gushing or dripping?

    the pore appears very fast and pale.

    he is very protective of the coffee machine and tends to bully his way through most things.

    he tamps and then taps the side of the porta-filler with the tamper about 4 or 5 times.

    he appears to use a lot of force while tamping.

    While I have been served bad coffee in various places his is the only coffee that I could not take a second sip.

    it tastes very over-extracted from my experiments at home.

    Not that I consider myself an expert in coffee faults.

    The answer's simple - he has no idea what he's doing, but thinks he does. On a Super Jolly, a 60 degree rotation of the collar can take the adjustment from ridiculously coarse (fast, weak and pale pour) all the way to the burrs being jammed against each other.

    I suspect this but it is nice to have it confirmed.

    The coffee is enough to make you cry.

    Time for a new barista.

    It isn't that he makes bad coffee, it isn't even that he will try to bully his way through, nor even that he thinks he knows even in the face of evidence he doesn't - it's that he hasn't a clue what good coffee is and blames his tools.

    I'd try one more time - get the rep back in to adjust the machine, tell him not to touch the grind settings and to use the same tamping method the rep shows - if he messes it up again it's walking time and you find someone who knows coffee and likes to make good stuff and is willing to learn and listen.

    It's the profits and goodwill of the shop he is screwing with - how many people will ever go back to a place that makes undrinkable coffee?

    Journeyman is clearly more forgiving than I am, I wouldn't even give him a second chance. If he can't even dial in a grinder he clearly has no idea of what he is doing and only helps to perpetuate the already poor image that barista's have. Why give him a pay-check when he is ruining your current and future business?
