    Any tips for dose quantity gadgets?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I know about the Scottie Callaghan dosing tools and for now an old credit card with two different arcs cut on the long sides is meeting my needs. But I have a question about bean dose, not grind dose. I have a doserless Rocky and dont want any beans left in the grinder after I make my shot. Im using a plastic measuring scoop to get the right amount of coffee into Rocky, but a few beans more or a few beans less can make a big difference to the final dose. How are others dealing with the issue of getting the exact same amount of beans into your grinder for each shot? Is there something like the Scottie C kit but for bean quantity rather than final grind level?

    DIY one from a business card

    Also level fill the basket you use with beans as a very accurate guide of the amount of beans to grind

    +1 for the scales. I use a cheap (<$15 shipped) set of digital scales from DX that are 300g max with 0.01 gram resolution. More than adequate for my needs.

    Digital scales, cheap, quick and very accurate, add to this a small brush to clean the chute and doser out and its pretty much a case of 18 grams in 18 grams out. ;)

    SeanSheep... nice scale! Do you mind sharing the brand?
    Something weird happened with mine today or my cleaning technique changed a bit... I usually get ~0.5g less than what I put in... I ended up with more than I put in! :(

    Ditto vyapadas question: I seached the DealExtrem site and cant find a digital scale that looks like SeanSheeps. They look cool.

    I dont want to breach any posting guidelines, so mods if this is too much then i apologise and feel free to delete.

    If you go to the site in question these are the product numbers, which are searchable:

    17486 300g/0.01g Black
    17481 300g/0.01g Silver
    17485 200g/0.01g Black
    17480 200g/0.01g Silver

    Mine is actually the 200g/0.01g Black model (not 300g).

    Oh, I had no idea DX was dealextreme, haha. Cheers mate!
    If mine ends up throwing a tanty I might need to get a replacement.

    Its not very often that I get to pull only one shot in a session but on those occasions that I do, I just use a standard 1 Tablespoon Measure x 2. Just strike the beans level with the rim and dump into the grinder. About 19g +1.0/-0.0 whole beans go in...

    After first pulsing the grinder a couple of times (to remove any old grinds, about 1.0g) then grinding properly and sweeping out the grind chute, I end up with about 18g +1.0/-0.0 of fresh coffee grounds. After dosing , I end up with either a perfectly level dose in the filter basket or a very slight mound that gets swept off.

    Makes a perfect shot every time (even if I do say so myself).... ;) 8-) and no need for digital scales or any other device.

    I use the palm of my hand to feel the level in a spare basket that is now only used for measuring beans to go into the hopper.

    Ive checked the accuracy of my hand using digital scales and its consistent.

    How do you account for the uneven grind that gets produced when there is no wait settling the beans onto the burrs?

    I have seen some people use their tamper as a weight, is this what you do?

    Weve got the same (or very very similar anyway) scales as sean, great little scales, we call them our drug scales as you can get such small quatities *;D

    I do tend to go on the level in the kyocera but in saying that some beans have a different weight depending on how Ive roasted them, so back to the scales :)

    Ill have to try the beans in the basket and see what happens too.

    Opened a new bag of beans this morning.
    There was a bit of variation in the bean size with a noticeable amount of smaller beans scattered throughout.

    Filled my basket and levelled with my palm.
    Weighed.
    Came to just short of 22g; readout was flashing 22/21.

    Emptied the basket back into the bag and shook then measured the same way again twice more.

    Both times I came within one or two beans of the same weight.

    :P

    Two-bean resolution. Youve gotta be happy with that. ;)

    Tried the levelled scoop method today and it was surprisingly accurate at almost exactly 9g per scoop.

    Cant say Ive ever noticed any inconsistency in the grind. It all looks uniform.

    But then Ive always done it that way, so I havent really got anything to compare it to.

    I did say my hand was accurate.

    Anyway, Ive just recalibrated my hand down to 19g as 22g was close to the updose limit for my showerscreen.

    19g fits nicely with a bit of extra wiggle room for puck expansion and those 1 or two beans than might have Jon worried for me.

    Re: Any tips for dose quantity gadgets?

    Thanks for some interesting comments. Im interested that some people are using their baskets as a measuring device. This is a question worth some scientific testing: IF unground beans filled the same volume as the same beans that have been ground, then using the basket would be an ideal measuring device, especially as I have four baskets that are used depending on who wants what strength shot - a single Silvia, a double Silvia, a double Synesso and a triple Silvia. I know scales would be the most accurate, but its another device to have on the kitchen bench, and testing would be needed to know exactly what weight is ideal for which basket. These figures of course would probably change depending on kind of beans being used. I like to try different ones and there seems to be variations in dose needed according to beans. My mission at present is to avoid sweeping off too much ground coffee and to avoid having to put a few more beans into Rocky if I did not dose enough. There must be a simpler way. By the way, Im very happy with my shots, Im just trying to avoid waste and/or extra steps in the process. As a relative newbie, Im learning that consistency in technique is paramount.

    The volume of ground beans is different to the volume of unground beans.
    The point is that I can gauge by the level of unground beans what becomes the correct volume when ground.

    Lets say that the unground beans reach the lip of the basket. Ground they dont reach that far.

    This topic has seen me pull out the scales to see if that is practical for me.
    Time-wise there doesnt seem to be much difference but as Richard A said, its one more device to have on the bench.

    Using the scales has been interesting though, as at one point I adjusted the grinder a bit fine so instead of going courser on the grind I decided to use the scales to use less beans for the next shot.
    As the beans aged, instead of grinding finer, I added more beans.

    This will only work so far though as eventually Ill be overdosing and so have to grind finer instead.

    Re: Any tips for dose quantity gadgets?

    I think Im becoming persuaded that I should get some digital scales. True, there may not be a need to use them all the time, but I need to have a picture in my mind of what a 21gram pile of beans look like versus a 18gram pile etc. Whether I use an actual scoop or basket may not be that important provided I use the same device consistently and know within a few beans how much to put into each different basket. Jaycar Electronics have a pocket-size one that measures up to 100gm for $49 and they are close to where I live (pictured). Id rather just get one locally than ship one in from O/S. Does anyone know of another local source?

    The bay of evil was where mine came from at about $30 posted from Melbourne.

    100g ones are great for checking bean load weights and when I am using an electric grinder at home for a single brew I tend to use them each time to save wastage or having to add a few more beans later. If I was doing it again i would consider getting a set of 1000g (0.1g) ones for measuring brew water and finished weights for pourover coffees* ::)

    Re: Any tips for dose quantity gadgets?

    Heres one for the "you got to see it to believe it" file. Im sitting here with a lovely single shot cap, after having used the single basket slightly heaped with beans as a measuring scoop. I had to level off excess ground beans before tamping! I honestly would not have believed that unground beans ended up so close to the volume of ground beans! What the...

    For the record Im using a single source Brazilian from Bellaroma, ground on 9th Feb and opened two days ago. Rocky is set to 7.

    Next time Ill use whatever basket I need leveled off with unground beans as my measuring standard and see how it goes.

    Ive bought a couple of different sets of scales from this mob over the years. They are a very helpful and decent outfit and I have no problem recommending them to anyone.... 8-)
