    Flat or convex Pullman Tamper?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hello all,
    Im in the middle of ordering a pullman tamper but im unsure about flat or convex?, could someone explain the difference(in coffee outcome, not whats the phisical difference :P)
    I primarily drink milk drinks but will have espresso 2 or 3 times a week, as you can see below i have a silvia and EM0480.
    I have also ordered a naked PF and some other stuff from coffeeparts and some WOW from Andy.....super keen for it all to arrive, maybe i should stop drinking coffee and go to sleep till it arrives! :o
    cheers once again for all the info!

    I too have just ordered a pullman tamper, and went with flat. I think the convex is supposed to make sure the edges of the basket receive enough compression. A careful tamp should achieve this with a well fitted tamper. Im a newbie so others will have more experienced wisdom.

    had a well-fitting convex coffelab, went to a well-fitting flat pullman: *far, far better shots... huge difference!
    the world is flat, according to my tamper and me... ;)

    This topic has been exhaustively covered over the years and a particularly good thread that has condensed most of the relevant information can be found here....http://coffeesnobs.com.au/YaBB.pl?num=1161240704/0

    The "Search Tool" is your friend ;),

    Hmmm,

    I got 15 results and that only went back as far as 2006.... Guess you need to be choosy with the keywords you use ;).

    Another way to do it that you might find easier, is to just use the power of Google and do a "site specific" search. This will (usually) turn up more results as the CS Search Tool is limited to 15 results per search. For example, heres the results using Google,

    Cheers mate :),

    Re: Flat or convex Pullman Tamper?

    Frankly, I think that whether or not you are using a flat tamper or a convex tamper is probably pretty far down on the list of important variables to get a good shot. That said, I think that the convex tampers are probably a bit more forgiving.

    In many of the trial runs for Gregs tampers, the various pro baristi that used them requested convex based tampers, which is why Greg now offers convex bases as an option. (Thanks for listening, Greg!) The strange thing is that they havent been very popular at all. Three possible explanations for this spring to my mind. The first is that it simply doesnt make that much difference. The second is that people at home might put more effort into making sure that everything is perfect for all of their shots, when compared with a barista who has to make fifteen coffeees in a row. This might alleviate any problems that might be caused by a flat based tamper as compared with a convex based tamper, if they are indeed more forgiving. The third is that we are stuck in a feedback loop; ie. one person buys a flat Pullman tamper and is happy with it, so based on that persons feedback the next person goes and buys one. Pretty soon, there are a whole bunch of people saying that flat based Pullman tampers are awesome and most successive purchasers opt to go with the crowd, rather than going with something that they perceive to be more risky because there arent as many fans of it. (I think that the classic example of this is when you look at discussion of the Rancilio Silvia in the US forums - in the USA you can buy a prosumer machine for only a few hundred dollars more than the Silvia, but to this day many people still opt to buy a Silvia instead purely because there is so much noise on the internet about it being awesome. Of course, much of those posts were generated before the prosumer machine market in the USA took off.)

    Personally, if I were buying a Pullman tamper today, I would buy one with a convex base. But I dont think that either base is the end of the world and Im sure that there are many people out there who prefer flat bases to convex bases. Im just glad that Greg continues to offer the convex option despite it being a poor seller.

    Cheers,

    Luca

    ok, points well made, Luca, so, *let me rephrase my earlier statement: my tamping technique is better suited to the flat base pullman i purchased than the convex coffee lab tamper i already owned... and therefore my shots improved dramatically once i started using the flat *base pullman.
    i would like to point out, though, that as far as i can ascertain the coffee lab tamper is a fine piece of craftsmanship, and for those who prefer a convex tamper, it would be a serious contender in the convex line-up.

    Agreed.

    I use my Anfims telescopic spring-loaded plastic tamper regularly during busy times - with no complaints.

    Grinder, machine, variable settings, barista gut-feel ... ;)

    Equally important, & symbiotic

    A tamper is just one of the factors that contributes to a fantastic espresso ... IMHO

    Disappear for one day and find this when I come back! :)

    We offer both because there are proponents of both profiles. I wont go into the arguments for and against in this thread as the thread Mal pointed to covers a lot of that. At this point in time I subscribe to the flat base philosophy, and last year over 500 people followed suit whereas about 10 opted for convex. I would echo Lucas three possible reasons for that, and add a fourth that I feel the philosophy of a flat base tamper is easier for a lot of people to understand - you want even compression, the baskets flat as is the group, why have a convex tamper? The arguments for particle distribution may be right or they may not be, but they dont make as much logical sense to many as the flat argument.

    So what do I recommend? I have no hesitation about recommending a flat base tamper, and Id recommend a convex if thats what you prefer. Weve had reports of excellent results from owners of both flat and convex based tampers which says to me that the other benefits available from a Pullman make at least as much improvement as the shape of the base. At this present time we have no convex so that makes it a very easy decision however! :) Im not writing off the convex by any means, and I must say Im getting some very good results on the bottomless portafilter from the convex tamper so thatll be an ongoing investigation - but having not reached the end of that process Im not going to pre-empt any outcomes which may or may not be reached.

    ... and being the craftsman you are, probably shuddering in horror at the thought of my u-beaut plastic spring-loaded telescopic tamper! ;D

    Fear not mate, 95% of the time I use a real tamper ;)
