    Breville Starting to make Powder

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all,

    Ive had my BCG450 for nearly a year now, and did the mod some months ago. *Ive always had a slightly inconsistent particle size, but generally not too bad.

    Last weekend I was playing with my new Hario, going through the motions to get it right for espresso. *After trial and error on the bad beans I pulled a shot glass with the good stuff from Pioneer Roastery (first time Ive used them at home). *Wow! The first half of the pour was all crema, by the time it settled I was left with about half crema, half espresso. *Not bad for my setup.

    But I digress. *I went back to the Breville to compare it to the Hario on the good beans. *At my usual mark for grinding, I noticed some sludge in the bottom of the cup (after I drank it), but wrote it off as a once off.

    A few days later I made a dessert with two espressos (good beans) and noticed the same thing - some sludge in the bottom of the glass, so its definitely repeatable.

    Ive never noticed it this bad before, but I AM using different beans. *Previously I was using good (but not specialty roasted) shop beans. *Does anyone know the reason? *Its a conical burr. *If the burrs were touching because of the mod, could they get blunter and show this behaviour? *Could it be from the different beans? *I will of course try the old beans as soon as I get the time, to see if its happening there too, but I expect it is.

    Thanks (more fuel for the grinder upgrade ;) )

    There is ya answer..

    That and your making the classical mistake of working to numbers..

    Old / Stale beans usually need a finer setting as they tear rather than grind as required..

    Fresh beans use a courser setting that what ya had for the beans that may be a few weeks old *and as they get older or sweat or hot, the grind has to be changes to get the best result in the cup..

    Thus; it is usual to start at one setting and over time get finer... When ya use new beans or fresh of the same type.. You usualy have to go back to the courser setting and test and define a new start point all over again..

    That is what coffee is about.

    If ya were buying old stale beans then a week or two may not matter if they are already months old..

    Fresh is best but also the hardest to manage... That is why many like stale supermarket or franchise beans... Never have to change teh settings as they are always set to fine to tyry to get something from them.

    Really? *Didnt expect that one!
    That and your making the classical mistake of working to numbers..
    Well, I didnt think I was, since I got the "mark" from trial and error with grinder and technique. *I just didnt realise that it was a moving mark ;)

    Now that you mention it, when I first put in the fresh beans from Pioneer (a week post roast) to the same mark it clogged up the machine and I had to back off the grinder. *I thought it was just inconsistency with the grinder.

    As I am learning :)

    Thanks!

    Re: A little sludge remains

    to resurrect this thread I now adjust the grinder depending on how old the beans are. I can usually get the "perfect" grind by the second attempt at new beans :)

    But theres still some grind inconsistency. It looks even when dry, but looking at the wet puck for some reason the larger grinds stay at the top and the finer ones push through to the bottom. Theres a tiny bit of dark sediment in the last few ml of the cup.

    Am I right in assuming this is the limit of the Breville grinder? Would my search for a GR RR45 or similar fix this completely? Im hoping so!

    thanks :)

    Yes.
    A good grinder gives you the same sized particles.

    Have you thoroughly cleaned out your grinder? I noticed on my old Sunbeam grinder that if I ground too fine, the fine grounds would stick inside the chute.

    Fine grounds could be still coming out with your courser grind if they were stuck in the grinder.

    Im eagerly anticipating that it will be, but trying not to get my hopes up too much!! Im expecting maybe a new set of plates, but well see.

    An interesting thought, but not that much ever gets stuck from what I can see.

    I think AM was on the mark since I can repeat the results consistently - fresh beans require a coarser setting, old beans require a finer setting. (Which reminds me, Im out of beans... must visit a sponsor)

    Thanks...

    But all I was doing was stating what I and others have observed; many times over teh years..

    However; it is good to see further feedback and that you able to reproduce it and thus clarify for your own piece of mind...

    The confusing thing for many is that there are so many variables, that the impact of even small changes are often over looked..

    While our aim is to KISS the problem is that the raw product and variables are any thing but!

    Enjoy the coffee road and the different learning paths it will take YOU on.
