What scales do you use?
As a bit of a coffee noob, I'm making some efforts to improve my technique, and I think dosing is the one area I could be more consistent with.
What sort of scales are y'all using?
My kitchen scales only measure in 2g increments, so they aren't much good. I've seen a small set for around $50 that are accurate to within .01g, which may be overkill...
Any suggestions would be greatly appreciated.
Digital and accurate to 0.1g. I have a cup that holds 40g approx and I pour that cup of beans into the empty hopper from my airtight container when I make 2 large flats early AM, any beans left in the grinder (negligable) get ground and tossed next brew and I reload another fresh 40g. If/when I change bean/roast I get the scales out to confirm that my 40g cup still holds 40g and it nearly always does plus/minus 1 or 2g. Simple.
Get a cheap point scale off eBay. Should only be about 10-15 bucks delivered. Get one with a 300g or 100g limit; they should have a resolution of 0.1 or 0.05g, far more than necessary.
They won't be accurate (same as most that people are using) to that, but it's consistency you need; knowing exactly how much coffee is being dosed isn't necessary as long as it's in the balllpark and is the same each time.
They're also useful for weighing your shots.
Accura measuring jug scales bought from a european foods retailer.
Has cup and millimetre/ounce markings.
Useful to weigh green beans prior to roasting as well as post roasting bagging. Convenient.
Just weigh, then put the whole lot into the roaster, or weighing then place into bags without mucking about with bowls, cups etc.
Accurate to the nearest gram, so you can also use it to weigh out your beans prior to dropping into the grinder or measure your dosage after grinding if you're testing out the accuracy of grinder timed dosers.
I also use the same scales for making bread and other cooking uses.
i've always preferred my 0.1g increment scale... but that said 1g increments are a lot less of a pain (ignorance is bliss) and doesnt get you fishing our the stray 2-3 beans that make it .6g more . ebay have em cheap and you can even get ones from large online small appliance stores. if you're into manual brewing the breville themometer and weighing scale is pretty cool - but pretty pricey too.
I just picked up a small pocket scale from Jaycar.
100g to .001 scale.
My previous scale was only rounded to a whole gram, which was ok, but the size of the dose was noticeably different if I lined a few up, in shot glasses.
I agree for convenience finding a shot glass or appropriate volume measurement is plenty close enough and in experimenting with several shots, once you have an accurate volume (measured on your scale by weight) it's a bit of overkill weighing every single shot... I just re calibrate with the scale when I change beans... :YMMV
I also started using a timer on the shot and combined with the scale does seem to help with consistency. It's now easier for me to isolate extraction temperature as a variable and experiment with that and it's effect on taste....
PM'd you with some details and a link about 10.30 this morning Andrew.

You're probably right, Dragunov, that true accuracy of the measurement isn't the goal, but consistency is. That said, my mid-level bathroom scales will fluctuate up to half a kilogram difference sometimes if I just get off and back on again, so a certain level of quality is required.
Loving the forum, by the way.
I've ordered a spoon scale but hasn't arrived yet. Will let you know how it goes.
got a 200g .01g scale for $11 delivered off ebay, works great, small footprint.
