    Lux/Nemox Grinder - Settings ??

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

    I now have my shiny new Nemox Dell Opera, which is basically a Mokita/Lux Grinder combo..

    I was wonder what settings people are using for a good strong and smooth coffee blend that are using a Nemox/Lux grinder with the Mokita/Fenice machines...

    The instructions recommend between 4 and 6 for a strong blend and 2 and 4 for a medium blend...

    Now that Ive figured out the right equipment I need to learn how to actually get the best from it ;D

    Helps hints, etc. welcome :-)

    Re: Lux/Nemox Grinder - Settings ??

    Hi again asqui,

    Re your grind settings..... this will depend on a few things, namley:-

    Whether you are using the Single or Double Basket in the PF, and
    The type, degree of roast and freshness of the Coffee Beans you are grinding, and
    The Tamping Force you ar using, and
    The ambient conditions at the time you are pulling a shot, and the list goes on.... :-?

    When you are just starting off with a new machine though, its probably the best idea to use and stick with the Double Basket until such time as you can confidently pull consistently good shots. I had a Lux when I first got my Mokita and I think from memory, I used to grind on a setting just below 5 to achieve acceptable shots with a Double Basket and coffee only 2-3 days out from roasting.

    Of course, this all depends on your having the coffee dosing on the money, the coffee evenly distributed with no voids and the tamping action down really consistent. It sounds like a lot of mucking around but once it all comes together, you can pull some exceptionally fine espressos.

    Anyway, Id start using the Double Basket on a grind setting of 5, pull your shot and see what happens. If its too quick, adjust the grind one step finer until such time as you are getting a 60ml shot in around 25-28 seconds. Once you can do this reliably and consistently, you will be 90% of the way there 8-).

    All the best asqui and happy brewing,

    Cheers,
    Mal.

    Hiya Mal,

    The pamphlet that came with the machine, as youve suggested, recommended a setting between 4 and 6 for a strong blend of coffee. The coffee Im using I bought only yesterday from the Coffee Company in Carlisle St, Melb. So Id assume its very fresh.

    My first pull I did with the double basket on around 4, probably tamped too hard (and unevenly... *SO* getting myself a pullman tamper!) and the machine just choked on it. I basically got a tiny few drops of coffee in the bottom of the glass, with oils sitting on top. I figured the grind was too fine or tamped too hard.

    I had another go on a higher grinder setting and still a similar result.

    I figured if I was going to be screwing up shots over and over that if I used the single basket Id at least waste less coffee, so I tried that.

    Im now on a setting around 6 and a bit getting shots around the 20-30 second mark with some resemblance of decent crema.

    Im worried that 6 seems quite coarse and maybe Im tamping way too hard or something, it really doesnt feel like I am :/

    After a few shots with the tamper built into the dell opera and reading a bit online Im thinking a pullman tamper might be the way to go.

    Is it common to change the grinder settings for a double shot vs a single shot? I guess once you figure out the right grind for each you can just remember and go back,... and as you said there are other inconsistent factors that will change often that youll have to adjust to.

    So much to learn!

    I think Ill be showing up to Melb Cafe Day next weekend to suck some more info in (and a few nice coffees down too :D)

    cheers

    Its great to believe... but believing a tamper is going to fix your problems could be expecting too much from an inanimate object which totally relies on your own and variable force to use.

    You could be overdosing, using excess pressure in the tamp, or both. A pullman or any other brand of tamper wont fix that.

    On the Silvia, the single basket it extremely difficult -- the double is a breeze by comparison. As Mal suggests, the double would set you o the right road quicker, even if initially you use more coffee.

    Good point there Robusto...

    Im using the double basket now and yesterday I pulled a shot around the 30 second mark, so Im just tweaking the grind and trying to keep my tamping as consisent as possible. Im noticing the pucks are getting firmer, but sometimes theres wormholes and one side of the ears on the portafilter will get more coffee while the other is trickling slowly which i think is just uneven tamping on my part.

    Not sure if youve seen the tamper attached to the Nemox, but i find it quite difficult to use because they are considerably smaller than the basket and have rounded outer edges. Also, the placement on the machine is close to the grind chute so it can be kind of awkward trying to tamp the edge of the portafilter closest to you.

    I expect that it will take me a while to get the technique down but having good tools at your disposal like the pullman tamper will help a lot. Besides that, they look purdy too ;)

    cheers

    I noticed the same thing Asqui,

    The tamper that came with the Mokita was very difficult to use consistently and I guess what the Pullman Tamper does (or any good quality Tamper for that matter), is make the tamping process a lot easier to become consistent. Its the consistency in the end that will make the difference :).

    You might think Im trying to teach you to suck eggs, but if you would like to read how I use my Pullman Tamper, just visit this thread....http://coffeesnobs.com.au/YaBB.pl?num=1137034177/0 and my post about two thirds the way down the page. It works for me and since Ive been doing it this way, never had a bad shot or a soggy puck ;D. Something to get started with anyway.....

    Cheerio,
    Mal.

    Hiya Mal,

    Thanks for the pointers/link. At this stage of my newbieness Im taking as much advice on board as I can :)

    I ordered myself a Deluxe Tamper yesterday afternoon and about 600g of roasted beans from CoffeCo in Melb. Once the tamper arrives Ill give your method a shot and see how I go :-)

    My "pucks" are shameful soggy abominations.. hah..

    cheers,
    Lachlan

    Re: Lux/Nemox Grinder - Settings ??

    Gday All,

    After I pulled the hopper out of my Quaha Neapolitana I found out that there isnt anything to show where the numbers line up with the adjuster. I adjusted it to its finnest setting and put the hopper back on so that N.o 1 was lined up but now Im all over the place with my grind adjustment. Can anyone tell me where the hopper is suposed to line up with. Also how do you remove the burs for cleaning or isnt it neccessary?

    Thanks for your help

    Thomas

    Hey Thomas,

    I have yet to pull apart my machine to get in and clean the grinder. It is actually on my TODO list for this weekend so Ill let you know how I go.

    Maybe you just need to remember what your grind was set to when you pulled out the hopper and then reinsert it around the same point?

    I dont think the reading on the hopper actually tells you much anyways -- How the shots pull should be your guide really, so as long as you know which direction is finer and which direction is coarser you should be OK.

    cheers

    Thanks Lachlan

    In my curiosity I turned the adjuster from lock to lock without making any marks and now Im having a lot of trouble getting a dry puck.

    Looking forward to your results,

    Thomas

    The marks on the Napolitana/Opera grinder are only a guide. Dont get hung up on trying to use them as an absolute.

    The technique you mentioned of getting the grinder touching then setting that as the "1" is great as it makes it (sort of) reproducible, but that shouldnt affect your coffee.

    You should always adjust the grind based on what your coffee results are coming out like.

    Heres what I always aim for......

    Use the same volume of ground coffee
    Use the same coffee levelling technique
    Use the same tamping pressure

    Then if I get a 10 second gusher, I know I have to adjust the grind finer.
    If its 10 drips in 30 seconds, adjust the grind coarser.
    If its in the ballpark of 60ml in 30 secs then its on the money (well personally I wouldnt know 60ml exactly, but if it forms thin mouse-tail flows in the first 5-8 secs, then thats what Im more looking at)

    To help out with a great technique, find a copy of John Doyles Espresso training manual, his ID here is "pinot".

    I use the marks on the grinder as a guide - I have an idea how different the outcome will be if I move it one mark, but I dont care if the grinder is set to half way between 4 and 5, I just worry what change I need to make to get the desired outcome. I actually have a tea-towel wrapped around the top of my grinder, so cant see the numbers anyway (trying to help reduce the noise impact on neighbours who probably dont appreciate coffee anywhere near as much as me!)

    hope this helps
    Brett

    PS: only exception to this rule is if I have to grind beans for relos/friends who dont have a grinder and want plunger, then Ill set it to a number I guess will be OK.
