    Mythos 1 & Mahlkonig K30 questions invited

    After 15 or so grinders over the last few years I've finally been able to choose my grinder b4 my coffee machine. If anyone's been interested in either of these, I'd welcome any questions and do my best to answer them, or run some grinds, then answer them. I will say this, the Mythos grinds different to any other grinder i've had, the de-clumping really does make a difference and has a very even grind, it also retains only a gram at most. The flavours thus far are quite different but i've got a long ways to go yet to really nail it!

    The Mythos retains around 5g of broken beans, of which a portion would be permanently retained until a clean

    Pulled the front burr off, swept all grinds with a small paint brush and weighed on an acaia lunar. A decent amount of that grind weight was compacted under the lower burr and would not have been able to mix with fresh grinds and exit the chute under normal grinder operation.

    My mythos retains only 2g, this by weighing grams going in vs grams coming out, done this a few times, same result each time

    is this in the normal course of things or is this based on retention from totally clean? if not post a clean i wonder if that will change eventually toomuchfuel, because otherwise it's like an infinite sink right and that can't be. have you had it for very long?

    I've never done an accurate test on mine but if I don't purge nearly a double shots worth (at least 10-14g) in the morning the first shot always pours badly. I'm speaking about my Mythos 1.

    Jono sorry buddy i get a great pour from zero purge but experience a flavour benefit of purging 2-3 seconds (my usual grind for a 19g double is around 8 seconds). Do you mean visually pours badly?

    With a Mythos Plus (similar setup to Mythos one with TiN burrs and clump crusher but without heater), I found a purge of about 5g (prolly less) is beneficial, but not much more needed. The first shot looked off without purge but flavor wise is not that bad (just slightly less crema). 10g+ sounds a lot...

    Total retention(including static retention) is about 6g between/under burrs, and about 1-2g behind the chute. There is also some partially broken bean bits(~3g) above the burrs, but those probably don't count. Measured by disassembling the grinder and then meticulously recover the ground/beans, then sifted.

    Maybe I'm used to purging for my Kony E and I don't need to go to that extent, but I like to be sure. I have made many shots without purging and they seem to visually suffer, I don't normally taste them if they look off, maybe I should. Yeah that's the figure I use, 3 secs most days.

    It really is an incredible grinder. The longer i have it the more i like it. I am experimenting now with longer running shots which are phenomenal, ie 45g out in 35s, 19g in at 94c. Don't feel i ever had that kind of shot work on previous grinders

    Hi toomuchfeul
    Great initiative, thanks.
    A couple of cafes (in Sydney) I often get an espresso from, use EK43 for their espressos and Roburs for milk based drinks. I have ALWAYS witnessed fines migration (from both cafes) from EK and wondered if it's just an EK thing or a Mahlkonig thing in general.
    Do you ever see any fines in your cup from K30?

    Whats consistency day to day like? Does the heating element help with this? I've only used these in commercial settings where they're always hot and have the fans spinning. I'd imagine the constant bean temp regardless of room temp would be beneficial for a home user? Or does the effect of staling hide this?

    I dont even know if my fan or heater comes on. Don't think about it. For me the things that are great about it are super low retention, no static or clumps ever, low grind speed, high quality even grind, low noise, and great distribution straight from the grinder. I

    I've only ever had the fans come on once so far in the life of my Mythos and it was an unusual day where I was doing higher volume while testing out something. The heater on mine is always on, I never turn the grinder off. I do wonder though what it does to the beans when they are sitting there for so long heating up? I wonder sometimes if this is what gives my first shot in the morning some in inconsistency, it seems to settle after a good purge?

    Considering its a lot lower than the temperatures experienced during roasting... I doubt its significant. It might affect the rate of staling but I don't see it changing the bean too much. No scientific basis for this though.
