MediumRoastSteam Dude. It’s the scale. If there was retention, and the scale was accurate, at some point I would’ve lost some coffee due to retention, and the scale would have told me so.

But the fact is that the scale never reads below the initial weight of the beans that I put into the grinder. As I said previously, I kept track of the weight after grinding over the course of one week, and by the end of the week I was up by over 1g. That’s not retention.

      MediumRoastSteam Probably not, given that the repeatability error is smaller than the amount of change in the dose that seems to be required to cause a noticeable change in the taste of the espresso.

      Just for kicks, I ran another set of weights according to your suggestion.

      1. Weigh the container – 109.0g. Note that this is different than the 109.1g that the scale usually reads. I didn’t mention this before, but the scale says that the container weighs between 109.0-109.2, depending on the day. Most of the time it’s 109.1g, but there is some variation here.

      2. Add beans until the scale reads 109.0g + 18g = 127.0g.

      3. Take the beans out. Now the scale reads 109.1g.

      4. Wait a while, and then add the beans one by one back into the container. When I finished, the scale reads 127.1g.

        You guys are working in 0.0 of grams

        Personally I really don’t think it matters that much

        If you scales are wandering like a clock fair do but in coffee I don’t think it matters.

        At work we mix paint in the 0.0g range and we even have a % of error were we don’t have to re calculate the mix.

        wilburpan While it is up to you if you would like to splash your hard-earned cash on a new scale or otherwise, would you be able to tell a difference on blind tasting if you were to make two cups with 0.5g/1.0 difference between them? I assume all other parameters are the same.

        If you can’t, why bother? If you can, you are a super taster and you are going to lose some decent cash. I assume, you can get away spending money. 😂

          I need a more accurate and responsive scale for my cottage setup. I have a Timemore Nano in the City but I recall seeing mention of another good one. Fyi I am not prepared to spend the $$$$ needed to buy an Acaia Lunar; I’d rather put that towards an espresso machine upgrade at the cottage. Any suggestions?

            If all you want is a repeatable and accurate scale (no timing functions) and one which is actually calibrated you can find one in any price range from RS Components or similar sites that cater to industry and universities.

            Thanks Sham!
            I do need a timing function for the moment, as my current cottage espresso machine (Breville DuoPro doesn’t).

            Bodum do a bistro scale

            If I’m reading this right, you have a Timemore Nano at one of your locations, and another scale that’s not a Timemore Nano in the second location. Why not just get another Timemore Nano?

              Probably will, but I saw a post with CoffeeTime Forum members crowing about a scale. Can’t find the post, so I was hoping to jog people’s memories.
