However choosing one is proving difficult, I think I have basically narrowed it down to either a spectra or a cocoatown, they seem to do the same things but are very different in price. In desperate need of help to choose!! I should also note I am in the UK.
I think this user is just a spammer…
I have to agree with Choklat when he says that if you are going to be buying a wet grinder for chocolate you want one made to make chocolate. Most small wet grinders are made to work a short time.
Is any of the models listed suitable for making chocolate? I notice you have buy links on the page so I want to make sure that members know what they are clicking through to.
Sarah – These small table top wet grinders were designed as kitchen appliances and are not designed to run for 8-12 hours or days at a time. It’s best to look for ones that have been modified (e.g., critical wear parts in plastic parts upgraded to metal) for making chocolate. I also think of these as lab machines, not production machines, as they are too small to make chocolate cost-effectively to support a profitable business.
I found good option for me on this site: https://cookingtimejournal.com/best-table-top-wet-grinders. This article is new, so information is relevant. I hope you’ll find what you need.
There are many ways to make chocolate from the bean. The route that most small startups take is using a so-called wet grinder as a “universal” – a grinder/refiner/conche. The reason for going this way is simple – it’s very inexpensive to get started.
The wet grinder uses two grinding stones against a stone base. Pressure is exerted on the grinding stones which takes the very large particles of cocoa and sugar and refines them to the desired size while at the same time doing flavor and texture development.
Now, there’s no need to fixate on 15 microns – it’s not just the particle size, it’s the particle size distribution, which looks a lot like a bell curve. No matter what you do in a wet mill you are going to get a distribution of particle sizes – some will be larger than the center/peak and some will be smaller. The location of the peak and the shape of the curve are related and important. It’s also important not to have too many particles that are too small as this can make the chocolate gummy and pasty.
Now that that’s out of the way.
The real engineering differences between the small tabletop Santhas and CocoaTowns are not all that great. They have small motors (too small), tend to have lousy drive belts, and plastic parts that wear down quickly. The main difference is in the way pressure is applied. The Santha has a knob you turn (adjustable) and the CocoaTown has a spring-loaded lid. There are lots of posts here on TheChocolateLife about the replacement belts and bushings for the small machines.
One of the main price differences you’ll see between the CocoaTown and the Santhas has to do with size. The CocoaTown comes in one large size (a 65 liter working bowl). The Santha has more sizes; the 20 and 40 liter machines are the most common. The size difference accounts for most of the price difference.
Well – not really. When you buy a Santha Spectra 40 it comes with an electronic speed controller. When you buy a CocoaTown ECGC65L it does not.
So which is better? It’s hard to say. If you are just starting out, you’re probably best off with one or three of the small tabletop machines to learn the process so to speak. Once you’re comfortable that you know what to do and that you have a business, it’s really all about how much production you need. If you are doing 200kg a month that’s one answer. If you’re doing 200kg a week it’s a different answer. If you’re at 200kg/week or more you also want to start thinking about bringing other machinery into the mix – a pre-grinder for the nibs and sugar and a dedicated conche so you’re using the wet mills only as grinder/refiners — or, you’ve moved on to an entirely new suite of equipment.
Thanks so much Clay for this. As with James, I’ve had the same dilemma and this information helps a lot. I am a silent member of this wonderful site and has been greedy of all the informations all the members has been generous of.I guess, it won’t matter which machine to choose from as long as it does the work and gives you the result you need. Kudos to you Clay and all the members. Cheers!
I’ve got a Spectra 40, but don’t think it grinds nearly as well as my benchtop Spectra 11. One thing I’ve wondered is about whether I need to ‘scale’ the time in the bigger grinder given the fact I’m doing bigger loads and, if so, how to scale. For example, does 3 kilos for 10 hours in the Spectra 11 equal 9 kilos for 10 hours in the bigger machine, or 9 kilos for somewhere nearer 30 hours?
The Premier Wonder gets the thumbs up from various people including Chocolate Alchemy … I’m pondering getting one.
Hi Clay, thank you for your helpful comment. I have since been looking at the tabletop versions, and have decided its best to practice with one of these. However I am now undecided on the spectra 11 or the cocoatown ECGC-12SLTA both seem very similar but I think the spectra is cheaper for some reason, but doesn’t come with warranty if used for chocolate?

Hi Lee,I have been looking at the machine you suggested and seems easy to get hold of in the uk, but it seems that people are unsure whether it would overheat if run for too long?
I’m in the same position as you I’m afraid. No idea! Based on what I’ve read here on TCL and the user’s thread on the chocolate forum at proboards it seems like a winner. Price is right too! Seems to me overheating is not a big deal. Just rig a fan to blow on the motor.
I’ve run many test batches in a couple of unmodified Premiers for multiple days with no heat issues. I also haven’t heard of anyone having any problems with them overheating.
That is brilliant news as it would seem that they bar far the cheapest machine. I was wondering why they are so much cheaper though…Which premier do you have?
I have the Premier Wonder Grinder which is the non-tilting 1.5 L version.
I have the same machine and have left it running for 50 hours straight without any fans/modifications. No problems what-so-ever. My machine would have done over 800 hours now without needing new belts or any new parts.
After your advice and recommendation I am going to go for a premier grinder. From what you and Gap have said the 1.5ltr machine seems to have no problems running for long period of times and has good durability. I was wondering whether or not you have tried/tested the slightly larger premier 2ltr grinder (tilting and no-tilting version)to see whether it is as good as the 1.5ltr one.

Hello. We love our Premier Grinders. We do four single origin chocolates in very small batches, so these small machines work very well for us. We also like being able to back off the stones so the chocolate stops grinding but keeps conching. After several hundred hours, the belt got a bit loose so the chocolate was conching but not grinding/refining the particle size down enough. We opened the top, loosened the nuts that hold the motor in place, adjusted the motor so the belt was tight, and tightened the bolts. Problem solved.
We also want to add our thanks to those on this forum who have contributed so much information and advice. We would not be making bean-to-bar chocolate without you.
Have you asked over at the chocolate alchemy forum (aka chocolate talk proboards)? They have a whole thread for Premier Wonder owners.
Thanks a lot for information, Clay! That is right i needed, very useful for me!
Unfortunately, we have not such a wet grinders here, in Georgia. Can anybody advice where is possible to buy one in internet by reasonable price and in good quality?.. Except cocoatown.com and amazon.com

My good friend Victor died at age 54 and Kudvic does not make the bean to bar equipment any more. Beware of scam.
I am in the proccess of making my own machine but i do not know the name of the stone…. i mean, i imagine that should be a special stone. Anybody know the name? or what kind of stone can i use
