    Rocky vs K3

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all, I am the very pleased new owner of a Silvia and also a Rocky grinder.

    Just wondering what your thoughts are of the Rocky vs the K3. The Rocky is actually new so was wondering if it was worth selling it and getting a second hand K3 instead.

    I dont plan on upgrading the Silvia at any stage over the next 3-5 years (will see how that goes ;) ) so only need a grinder to suit the Silvia.

    Just pulled my first shot from the Silvia with grind from my Breville (BCG450 conical burr grinder) and it was horrible! :D Not sure if it was cause the grind was too course or my tamping skills need alot of work. Mind you, the plastic tamp is really horrible to try and tamp with as there is ALOT of room around it in the basket.

    Re: Rocky vs K3

    The second part of your post, The BCG450 is a horrible grinder that needs modifications to be anywhere near good enough for the Silvia (which is notoriously finicky about the grinder its paired with)

    I would work with the Rocky first, find out how it works, and see if you can live with it before deciding on whether or not its worth upgrading. It is a solid machine, and long lasting too, itd more then last long enough for your planned next upgrade.

    Oh, and Relegate the BCG450 to doing French press, its perfect for that ;)

    Re: Rocky vs K3

    I use a Breville Smart Grinder BCG 800 with my BDB and get great results.

    I also have a BCG 450 which I do not use for coffee. It makes a good door stop.

    In other strings at this site several members have said they are using a Smart Grinder with their Silvias with good results and while I have not used a Rocky, the general feeling here is that the Smart grinder is superior. You may have to pay a lot more to get something better.

    The SG can be bought for about $200. It is often said to buy the best grinder you can afford.

    I suppose you stop upgrading when the money runs out.

    I disagree, there is nothing finicky about the Silvia, its a simple process to get the grind and dosing right, once you have it worked out the Silvia Rocky combo will produce excellent coffee and should give years of trouble free service.
    Cant comment on the Smart grinder, Ive never used one, however I owned and used a Rocky for many years and found it to be a very good machine. :)

    I disagree about this "general feeling" The general feeling seems to be that the Breville is barely adequate for espresso, with many people complaining of metal on metal crunching sounds when trying to grind for espresso. And it often needs to be modified out of the box.

    The Silvia is no more finicky when it comes to grinders then any other non-appliance espresso machine. It just needs a real grinder.

    I dont know of any grinders cheaper then the rocky that have a metal burr carrier.

    Re: Rocky vs K3

    Thank you for all your replies :-) I had no intention of using the Breville I owe with the Silvia, planning on selling both the Breville coffee appliances together on eBay.

    So, basically wondering if I should sell my Rocky whilst its new and upgrade to a second hand K3.

    From what I can tell from having a read through other posts etc. is that although the K3 is a beautiful grinder, I think the Rocky suits my needs at this time to use with the Silvia.

    Here goes, going to open it up and give it a burl later today. HOW EXCITING!!!

    PS. Had a wonderful little lesson on how to use my Silvia this morning from Steve (I think thats his name?) from Chosen Bean in FGully this morning. Thank you :)

    Be prepared for a "learning period" with Silvia.
    Hopefully Steve taught you how to gauge the correct brew temperature ( there are several possible ways),.. so that you get consistent results. It can be tricky.
    Search these forums or ask if you have problems.
    The Silvia really benefits from a PID upgrade ( or a temp gauge) to simplify the operation.

    I would like to get a PID eventually but my budget got a little stretched when I bought a version 2 thinking that I was getting a 3 so had to pay for the upgrade for the steam wand.

    As for the temp, Ive been following the temp surfing clips on FB for the Silvia. I presume thats what you mean?

    Ive made a mess of this forum with two posts going on about the Silvia and then the Rocky :( Sorry.

    Re: Rocky vs K3

    My Rocky grinds really well for my Lelit which is similar price point to the Silvia (mine has a PID thank C...). My grind number is usually 9 and may go down to 8 when the brew passes through a bit too quickly. I think I have my Ps on these days so a lot to learn but no longer a complete novice but I can rip out some really nice lattes on demand. I dont store many beans in the Rocky , maybe a day or two of usage - the rest stay sealed away in a cool, dark spot.

    Not planning on storing my beans in the grinder, only dosing what I will use for that shot as I switch beans throughout the day. Of course that would imply I need two grinders wouldnt it ;) ;D

    Do buy the best you can afford. The Breville is good, the Compak K3P way better. In between are plenty of other good grinders.

    With grinders, you really do get what you pay for. Both of those I mentioned punch above their weight in my opinion.

    Good luck!

    "Sunbeam EM0450/0480 is the minimum level for a decent espresso grind. The Breville is currently regarded as one of the best buys under $400. Both are recommended, and are quite capable of serving with your Silvia".

    There are also plenty of favourable statements about the Smart* Grinder on Breville BES900 Dual Boiler - Owners thread.

    OR... you might consider a grinder with a removable hopper, and get a 2nd hopper, so you can quickly swap bean supply ! :D

    Id even (almost) go so far as to say that mosy (many) BES900 owners got the Smart Grinder as part of a combo deal and most of the posts I have seen about the grinder have been very positive. In fact the only reason I didnt end up with one was because they were unavailable when I got my BES900.

    I like your thinking :-) Now that Im finding alot of things I need for my silvia I think Im going to stick with the Rocky and think about a grinder with interchangeable hoppers down the track ;)

    Not a good idea Pobie, coffee beans sitting in hoppers go stale fast.
    Keep your beans in sealed bags with one way valves and all will be well. :)

    Re: Rocky vs K3

    I am one that had a Rocky but now use the BCG800. I find the BCG800 much more user friendly then the Rocky and grind quality as good with less clumping and retained grinds. I wouldnt expect it to last as long as the Rocky though given the Rockys rep and the fact the Rocky weighs more than three times the Breville.
    I have never used the K3 but would swap a new Rocky for one for sure.

    The Silvia is a good machine ive had mine for a couple of years and still going strong. Let it heat up, get a decent basket (vst ridgless 21g or similar) and you will love the beast.

    Re: Rocky vs K3

    I had a Rocky for about two years and got a K3P when I upgraded my Silvia to a shinier model.

    IMHO the K3P is a way better grinder.

    Myself and I am sure others, would be interested to know what you mean by: ".....IMHO the K3P is a way better grinder...."

    Would you care to elaborate as I am sure it will help others. What do you mean by "better"?

    Ill take a stab and say that what he means by better is that its; greater than, superior too, its perfomance exceeds, etc...
    Better in regards to the quality, value and performance. That is how I would take it.

    Re: Rocky vs K3

    Thanks for that, but I was actually hoping for specific reasons why tiddler thinks (after owning one and then the other) one is better than the other.

    Quality, value and performance dont mean much without the supporting info.

    For example, rocky is a 50mm grinder the the k3 is a 58. Reviewed by someone with the requisite expertise in the operational side of the grinder, the difference in grind quality should be very small if not very possibly undetectable (depending on the individual reviewer expertise in cupping), and the only diff in the delivery will be that the 58 will deliver grinds more quickly than the 50.....except that there may be a difference in the type of delivery wrt to the resulting level of clumping or amount of grinds retained etc.

    All of this wrt "in home" use, as there is no point reviewing from the point of view of much greater volume put through as would happen in a work situation, when this is a home use situation.

    Or.....it could be that there may not be a large difference between them in any way performance related, but the "client ease of use" or overall positive or negative "useage experience" or "satisfaction index" is greater for one of the grinders in the reviewers point of view....and this may well be just as legitimate in deciding which grinder is "better than the other" even if it may not really be significantly performance related.

    And we then I believe need to consider, that often in these pages, very big things seem to be made of what could be described out in the real world, as being very small differences between pieces of equipment, which in turn, puts some equipment into a "preferred" category, while other pieces of often very good equipment are relegated to the waste bin as in, to be walked straight past in showrooms and ignored.

    From my point of view all of this this is quite interesting and is what I expect to see to help individuals differentiate and make serious purchasing decisions for themselves, when choosing between two pieces of equipment, be they significantly different in actual performance or more simply, different in the total "client experience".

    Therefore, still happy to hear from clients that have experience with both these grinders in their home.

    As a keen fisherman I visit a bunch of fishing forums and the amount of technical jargon and opinions for and against comparisons of fishing reels puts coffeesnobs discussions to shame. In the end a $2 handline can outfish a $2,000 reel, depending on the human on the end of it.

    To some extent I reckon the same applies to coffee brewing!

    Its very true. Ive got a Sunbeam 0480 with my Silvia and during my learning curve it was easy to blame it for my own errors. Now Im more proficient and the grinder works just fine, electrostatic issues aside.

    This thinking alone stopped my buying a new grinder today. Learn proper technique then blame the gear!

    Re: Rocky vs K3

    Hi All
    I too have a Silvia and Rocky combo. It has been faithfull for some 7 years now and never missed a beat. I pull my hopper off to get to the burrs and clean stale grounds out and check for wear. I was told the rocky is a 58 burr grinder (I never checked validity) and is off a semi commercial quality build. The stepless grinder is perfect for small adjustments depending on age and type of bean youre using for your machine. Dont let anyone fool you into believing Rocky is somehow not a worthy unit, because like others have said, differences maybe minor. You will get many years out of Rocky. Silvia is a good girl too, if well maintained, she will do you proud for many years.
    I have not modified Silvia like others but still manage to pull a great coffee. I think if you need to modify your machine, then maybe this is not for you. Im going to upgrade to a Giotto Premium Plus as now I would like a more precise machine with a few extras.

    Good luck with Your Rancilio duo and hope you get alot of enjoyment out of them for a long time to come. :)
