    Which Grinder to pair with Rocket Giotto v3

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Upgrading from a Baratza Preciso because of excessive clumping and also it can't hold a grind setting.

    Hopefully my next grinder won't have these problems.

    I've narrowed it down to:

    mazzer mini e
    mazzer kony e

    I'd love the Kony but from what I've read, most owners end up modifying it significantly - are all these mods necessary for home use? I'm referring to a custom hopper made of a PVC pipe - is that mod difficult to do and is it necessary? What would happen if I leave it all stock?

    That's a big jump from a Mini E to a Kony.
    A bit like comparing a Hyundai and a F350 if you don't mind me saying.
    In my experience with your Espresso Machine I would suggest to lift the base line up to a
    Mazzer SuperJolly / MacapM4 as the best base choice to get the best out of your machine / bean choice.

    Obv the higher end grinders can give a different result in your shots that may not be easily obtainable from smaller
    Base level grinders. So the budget /choice is yours.
    The above doesn't take into account your requirements in relation to bench space / cupboard heights / budget / style
    Or theKitchen CEO's general taste /style / 'it just doesn't go in this (MY) kitchen - groin! = get rid of it now) ;(

    As a tip once you have your new grinder search out the best / freshest roast you can source so that you can dial in the Baseline for the grinder / machine combo / taste of shot you prefer. (Email Andy @Beanbay)
    I noted where that is on my grinder and you can then refer to that with any new beans you source / ageing beans
    in your cupboard etc. Its also just a very good reference point to have in future shot solving questions you might have.

    Thanks I appreciate your concern - I've already factored those concerns into my shortlist. The kony will fit, I'm leaning towards it because it seems to be the only choice for a conical made by a reputable brand with lots of owners in the marketplace and therefore lots of community support which is important to me (I don't want a machine with much less owners as the community support and parts availability may be much less). Budget is fine.

    I would've just bought the kony without further thought but what worries me is how most owners seem to eventually mod the hopper into some sort of pipe. Wondering why they do this and what would happen if they just left it. I know it's not good to keep too much beans in the huge hopper for home use, they go stale etc - what if i just left a small amount in?

    Hi scientist

    Because of the large burr sets in these big conicals (they are designed for high capacity commercial use) they are really optimised to have a reasonable number of beans in the hopper - think 250g-500g at least to get some weight onto the beans being ground to give consistent grinding.
    The micro hopper and weight on top allows you to have smaller amounts of beans but a similar down pressure - but realistically you still end up with at least 100-150g in the bean path.

    So your choices if you really want a Kony are:
    • Keep 250g at least in the hopper and drink more…
    • Micro hopper option
    • Single dose and put up with frustration of uneven grinding and wastage

    or …

    • Buy a small grinder (M4, M4D) and single dose if you're worried about retention

    or …

    • Buy an OE Lido from Talk Coffee and get the same basic flavour profile as a Kony for a fraction of the price with none of the mods - and avoid save time on bicep curls at the gym!

    Cheers Matt

    BTW I've got a Robur - which are the same issues mentioned above - only upscaled!

    I'll throw another couple of contenders in. You can can go the gourmet hopper from a K3P if you wish. They're an awesome grinder.

    Compak E10 Conic OD | Talk Coffee
    Compak E10 Master Conic OD | Talk Coffee

    Cheers

    I've had a Kony-E for a number of years, kept it totally un-modded, have not even removed the static screen which many people do. My thinking is, Mazzer have no doubt gone to a lot of research and design to develop the kit, so why fiddle with it?

    Pro's - Does exactly what's expected of it, fantastic grinder all round and especially for straight espresso and black coffee. Pretty quiet by comparison to many domestic grinders
    Con's - Largish footprint, with a large hopper. Some grind retention for domestic use, so therefore some coffee wastage

    Take into consideration it is not designed for domestic usage and cater for that appropriately and you have a great grinder. I only put in enough coffee for each session, and run it all through each time. I roast so never a shortage of coffee.

    Having said that however I think the marketplace for more appropriate domestic friendly, (smaller, cheaper etc..), grinders provides much greater choice now than when I got my Kony, so suggest you ask CS Sponsors for advice, and go touch & feel before spending big.

    Are you doing all your research by reading? As per GrahamK's advice, if possible pay a visit to shops where they sell a range of grinders you can check out. Talk to the store owner about your coffee preferences and more importantly see how the shots taste. If you are going to outlay over a grand for your next grinder, you want to be sure. If you drink only milk-based coffee, then there isn't much point in buying a high-end conical

    I'm curious why you haven't included Macap or Compak in your short list. There are reputable with plenty of owners. These can also more easily accommodate a smaller hopper.

    I have a Rocket v3 replacing an older Rocket that is now at work. About 4 years ago we got a Kony-e. Took a while for the burrs to run in. I have absolutely no regrets or buyers remorse. I did modify the bean hopper area as I only grind a few beans daily. I did remove the static screen. The only area where the design could be improved for home use is a sharper angle on the grinds shute so grinds were not retained. With this grinder there is no possible 'upgraditis', you have arrived at an ultimate point. I have perfect grinds and give our super good Cimalino's Cottesloe coffee shop a run for its money. It's only just a nose ahead - most of the time!
    Footnote: some Kony-e folk don't modify and clear the old grinds with a first grind to clear the shute the start with the second grind - me I just like to fiddle.

    Agree with "dumiya"...

    It's really a 'horses for courses' kind of thing with large conical grinders that are intended for commercial use but purchased for home use. In a pure sense, they are not really fit for purpose in a home setting so you can either live with the grinder 'as-is' or apply a couple of really simple measures to make them a more friendly grinder for the maybe half-a-dozen coffees per day, one may consume at home.

    These simple measures are not really mod's as such since all that is done to the grinder itself (in my case anyway) was to remove the screen (completely reversible) to facilitate brushing out the discharge chute area, and the use of a small plastic cup (about the size of a Yoplait container) instead of the 1.5Kg bean hopper. That's it...

    Like "dumiya" also pointed out, lots of people are entirely happy to leave it as it came in the box. Just have to remember to discard the first 4-5g of ground coffee if it's been a little while between sessions - not a biggie. Of course, if you and yours drink mainly milk coffee drinks, then a large conical grinder is really wasted in that situation. Far better to consider a Macap M4D which grinds just as quickly as a Kony-E and a far more friendly domestic use grinder all round.

    Also, as "flynnaus" mentioned above, you really should pay a visit to one or more of our Site Sponsors or other reputable specialist retailers, so that you can get some hands-on test drives of a few different grinders. Will be much easier to make the decision that is right for you...

    How many coffees you make a day?

    Is the HG-One (manual grinder) a consideration? Kony burrset in a sleek package, and not nearly as much of a chore as I thought it would be.

    I'f you're going for the electric dosing models I'd suspect not, but I bring it up on the offchance.

    scientist, I can understand much of your choices are based on reading forums such as this one.
    But if you have ended up at those choices, then I suggest you research more, since , as has been suggested , there are many more options that would satisfy your needs.
    Really, the MMini is not a the leader in its class ( size, performance , value, etc) any longer, and the Kony has many equals.
    Also there is a huge choice of excellent grinders in the range between those two.

    thanks for all the suggestions, I'm still leaning towards the kony after more thought. I think I'll be comfortable doing the mods to make it more home-use friendly.
