Having used bensynnock’s method to accurately determine how many beans you need use a pill counting tray to measure the correct number.
How does that work for different size beans?
Apologies for triggering! I think Quiff is talking about beans here though, and they could control the process a bit by putting a sticker that says “no squishing” on the side of their measuring pot 🙂Measuring things by volume makes even less sense when the objects are larger (I’ve seen a U.S. recipe that listed a cup of fresh apricots FFS). With irregularly sized objects, the order in which you put them in the container can make a difference and also, how do you determine if you’ve optimally packed the beans?
https://en.wikipedia.org/wiki/Packing_problems
I think it’d be easier to use an 8-dimensional volume and hand-carve the beans into perfect spheres as that way, you can use the optimal E8 lattice packing.
BECAUSE THIS IS AN IMPORTANT ISSUE, I have just tried loading my digital scales with cocktail sticks (approx weight 0.2g) one at a time. I have no coffee beans. I see similar behaviour to that you describe. I suspect the scale is doing some kind of processing to filter out electrical noise, resulting in small changes not being registered.One solution would be to lift the receptacle you use to hold the beans off the scale between additions.
When I was at university (a long time ago) we had to do a lab where the task involved making a sintered metal part (powdered material heated and squashed together) The part need a certain mass of material to be right, but we had to propose ways of making them quickly. The problem was that the weighing systems we had took time to stablise, so it was difficult to do “fill until right weight” as you have found.
The answer turned out to be doing it by volume instead: making a “cup” of the right size to hold near-enough the right weight of material when filled to the top. Could you do that? I’m thinking about the scoops one uses for e.g., infant formula or protein shakes, where you are encouraged to “level off” the load with a knife to get a consistent amount in each scoop.
Then, obviously, do some blind tasting with slightly different amounts to see what tolerances your palate can tolerate!
I’m properly triggered by that.
I hate the U.S. system of measuring cooking ingredients by volume – it makes no sense at all which is why every other country in the world uses weights.
The “volume” of coffee grinds would depend on whether it’s tamped (and what force is used for tamping) and the size of the grind.
Incidentally, to continue the
Incidentally, to continue the other coffee related thread, I discovered someone selling elephant dung coffee: https://blackivorycoffee.com/
There’s definitely diminishing returns when you start paying those kinds of prices for coffee (£150 for 40g).
Anyhow, you’re better off weighing the ground coffee.That’s a fair point. Experience with my grinder shows that weight of beans in = weight of grounds out (albeit some of that weight out will be retention from the previous grind). Just seems a bit suspect to say it has 0.1g precision if a single bean which weighs more than 0.1g can’t provide the force to register, so that you can add 20+ g slowly without changing the reading.
They’re kitchen scales and thus not particularly sensitive. There’s also the difference between precision and accuracy – they might have 0.1g precision but only be accurate to within +-0.5g. If you want accuracy, go for some chemical scales that are usually in a glass case to prevent air movements from disrupting the measurement.
Personally, I’m too lazy to weigh my coffee all the time – I use a Baratza Sette 270 which has a time setting and grind directly into an Aeropress for 5 seconds. (The Baratza is somewhat overkill for Aeropress coffee which doesn’t demand as much accuracy as espresso).
I think that’s common for
I think that’s common for most digital scales. Maybe give the scales a little tap to get it to re-weigh properly. I assume it’s something to do with a single bean not providing enough force to get the scale to update its weight, but that’s a guess.
Anyhow, you’re better off weighing the ground coffee.

Count 100 beans and weigh them to get a better mean weight. In fact, do that 100 times and work out the variance and standard deviation, and plot a graph of all the recorded weights. To go even further use R to generate a statistical model for the weight of beans, perhaps using other measures such as air temperature and humidity also, to enable you to determine the likely weight of any future bean counts.That should be done for each different bean type and different roasting profiles as the moisture content will vary.
My preference is to weigh the ground coffee as that’s what I’m using to make the coffee drink. You could accurately know the exact weight of the beans, but then lose a little bit when grinding as electrostatic forces can prevent all the grounds from landing in the appropriate receptacle (I think some people use aerosolised water to control the conductivity of air).
I’m a fan of the Earth Pak
I’m a fan of the Earth Pak drybags. They’re cheap, durable and completely waterproof. I’ve got a fairly massive one which I got so that it could fit a standard boardgame size box in it easily, but with the roll-down top, it shrinks down to a manageable size. Been using it for years, often with a heavy load and it’s still going strong. It’s so much better than so-called waterproof backpacks which let in water through the zips.

A disgustingly insulting comparison, very rude to babies. Babies stop whining when they’re given what they’re asking for, Reform got what they (at any rate their predecessors) were asking for in 2016 and have continued whining ever since, always moving onto the next hate target…Also, babies don’t try to divide peope and get them angry. They also don’t care about the colour of people’s skin.

I love the Right Wing Stuff … If your happy for migrants and Pakistani heritage rapists to abuse your children you are not wanted in this country… The Right wing are the majority of the British population ….. The left … who are they, why do they hate everything about this country … There’s A War Coming …. You will have to pick a side … ????You’ve fallen for their rhetoric and lies.
The war isn’t between Left and Right, but between the rich and the poor. The “left” wants to help the poor become better off and the “right” wants the richest to get even more money. If you love your country, then you shouldn’t want the rich to own more and more of it. If you hate this country, then you probably welcome the Tories/Reform aiming to destroy the NHS so that they can sell off lucrative contracts to their mates who can then fleece everyone with sky high medical bills (see the U.S. where medical bills are the number one cause of bankruptcies).
Don’t let yourself be tricked by wily politicians who are only after their own enrichment and care not one bit about you – they’d happily sell you off to work in a Victorian factory if they didn’t have to abide by human rights laws.
(Incidentally, if you really care about stopping rapists, then you should be caring more about the top rung of society that Epstein used to ply with vulnerable girls – it’s the rich white males that are the real problem).
Also, if you really care about immigration, then why would you want to follow the advice of Farage who was instrumental in tricking us into leaving the EU which now makes it harder to control immigration as we no longer share information with e.g. France. Farage is literally banging on about a problem that he helped exacerbate.

No idea because with long threads it’s hard to know what you replied to… Aha! So now the merit of the wtjs (patent pending) italicized message beginning becomes apparent!I find it easier to just use the “Quote” button, though your italics then gets included which confuses matters. Also, the text within a Quote block doesn’t appear in the “Latest Comments” at the bottom of the page, whereas your italics does, which makes it less clear what you’re actually saying without having to go and read your comment.
