    0.1 gram scales?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I have been searching unsuccessfully for a kitchen scale that will both hold my grouphead and basket, and measure to 0.1 gram. I'm sick of looking and wonder whether I am the first person in the world to want this. I'm happy to stick a little plate on top to hold the grouphead while being able to read the weight, this is what I do now with my unsatisfactory 1.0 gram scale. I calculate I need a platform of at least 12 cm.
    Any hints much appreciated!
    Dawn.

    I bought a scale from ebay that is pretty much the same as Market Lane Coffee sell for much, much cheaper. I won't post the link as it will probably get removed due to site policy.

    It comes with a lid that you can turn upside down and sit on the scale it supports a portafilter will - the scale is also small enough to fit on the drip tray under the grouphead.

    I've since upgraded to a Acaia Lunar as I got one for a steal on ebay.

    I use Brewista - not the cheapest, but can be had for a relative bargain, at the right time on ebay.

    This is what you want. American Weigh Station make absolutely the best scales on the world market, hands down!

    What do you REALLY want in a scale?

    You need the scale to be calibrated by the user at any given moment, This scale can do this.
    You need 2 x weights to calibrate it, This comes with 2 x 200g weights.
    You need an AC adapter so you can use power, who wants to change batteries? Even though I've had this scale for 2 years and never changed the batteries once but its nice to have! (Comes with 110v-240v adapter just twist the prongs from American to AU)
    It also supports 500g capacity with 0.01g.
    (You might not think that's enough, however you tare the portafilter off first and then dose and it sets the scales into negative weight, that's how good these scales are!!) Just make sure your portafilter is not over 500g.
    Another way is to dose into a cup first then put into the portafilter - most cafes do this!
    If you accidentally drop a portafilter on any scale it will damage it and throw the calibration out - to avoid this dose into a plastic small cup first but entirely up to the user.
    Oh, Also comes with a bowl and batteries included.

    Read the reviews on Amazon, they're amazing scales and I got mine for less than $40 shipped - Shipping took 3 days from America via Amazon. YMMV.

    I bought a set of scales of ebay also. About $25 search for coffee scales .1g
    These allow me to sit my PF on diagonally, slim enough to fit on the machine as well.

    I think one of the more important features is speed of returning a weight. These are ok, but if you are aiming at a weight when extracting I need to stop the flow about 5g early (~2 seconds)

    Haven't used more expensive scales, but from the videos it seems they are a bit quicker.

    Sette 270w?

    Sorry, couldnt resist.

    I have a cheap ebay scale, very consistent, the measuring plate is small, maybe 5x5cm?, but I can site the PF including basket on it for the times I used it for that purpose. It was under $10 delivered, and does 0.1g to 1kg. Quite handy for a variety of things.

    There are heaps of options that will do what you need at varying price points.

    Cheers

    An alternative - I bought one of the Tiamo stainless steel dosing cups. I grind into that - it sits nicely on my small eBay scale (about 115gms - tare it out) and allows me to stir the grounds to get rid of clumps and Id like to think the metal cup reduces static electricity.

    The cups fits the top of my baskets perfectly so I can upend the grounds into the basket without spilling any - no spillage in grinding process either.

    I then use the small scale to measure the shot going into the cup - scales and cup easily fit under the installed portafilter.

    Perfect - was looking at these but couldn't find any reviews. Do you grind into the cup as it sits on the scale? Or weigh the cup and then adjust the quantity?

    I have a Brewista smart scale 2 coming in a day or two...

    I put the Tiamo cup on the scale and tare (zero) it. I then grind into that cup. I have a Quamar Q50 with a timer and it can generally get within a gram of what I want.

    So I grind into the dosing cup; check the net weight and then give a couple of little bursts to bring it to my desired weight if needed - usually within about 0.2 gram after practice.

    I haven't tried sitting it on the scale under the grinder - for two reasons:
    1. There is a stainless steel "prong" for the portafilter to sit on, so the vibration would probably make the scales and cup fall and I suspect the vibration would throw off the weighing.
    2. I have no quick way of stopping the grinder when the desired weight is reached, without also compromising the weighing process - plus grinds will still come out for a while after the machine stops, so you have to anticipate.

    Your set-up might be different, but the zero/weigh process works for me.

    So I bought the Brewista scale, and also the Tiamo dosing cup. It has been a game changer. I hadn’t realised just how far out my ‘estimates’ were from reality. Coffee experience has soared, its been the cheapest upgrade to my coffee ever...

    Having said that I have ordered a $15 eBay scale as a back up/second unit (for beach coffee). I won’t be sitting this on my drip tray during the extraction like the Brewista, but I can weigh the cup afterwards. I haven’t seen an alternative to the Tiamo surprisingly so may have to get another. Unless anyone has any DIY hacks involving yoghurt pots etc...

    A consistent dose is one of the basic steps toward good espresso.

    A Portafilter stand for use on small scales. Shouldn't be too hard to knock one up yourself though. There's some plastic copies floating around also. An enterprising individual could probably use chromed bent rod to achieve a similar shape by following the shape of the edges.

    A 3D printer would be handy...

    Just don't try tamping while resting it on something 3D printed in the fashion of the item pictured.

    I have some cheap eBay 500g scales for bean weights. It is 0.01g resolution. Easily measures 1 bean weight. Portafilter blows out the 500g limit though, and it's too small to fit a portafilter on.
    But I use it to pre pack my beans into single dose sized ziplocks. Then repack back into the suppliers bean bag and freeze the lot.
    If going to work for 4 days, grab 4 ziplocks. If home and ready for espresso, grab 1 baggie.
    Works well for me, though the initial weighing and bagging is a bit painful for 1kg of beans.

    Having used the TiAmo for a few weeks I'm pretty sold on the grinding into cup concept now (see above). Much less messy and no clumping. So you don't really need your heavy portafilter on a scale.

    Have you tried single dosing beans into the grinder? Weigh whole beans into the cup and then dose into the grinder. If you have any sort of consistency in retention, you may be able to adjust for this in the bean weight to achieve the desired grind weight. If not, this message will self destruct in 5 seconds....4....3...

    I know this was directed at steve7, but I would consider this if I was the ONLY user of the grinder. Wife and son prefer to find a few beans already in the hopper...
    I'm not going to try to change their practice if they are happy enough with their own results They won't be bothering with scales and dosing cup either

    I did try something close to that, but the retention weight in my grinder is not consistent - it is give or take more than a gram - so could be out on that last bean! It was just too much fiddling.

    I find the timer on the grinder is best set to say about 11 grams and it will give +- 0.4 grams, depending on the state of the beans. If I want a 12 gram dose I just “blip” the grinder a couple of times and give the delivery cone on the Quamar a bump. I can get to within 0.2 grams on my cheapie scale without too much fiddling.

    If anyone is interested there's a set of Brewista 2 scales on fleabay (273663488250) at the moment for $35 including postage from Doncaster VIC (to me in Sydney at least). Used in a Melbourne cafe. I bought an identical one from the same seller a few days ago for a friend and it was fully functional but with some marking from cafe use.
