The Premier Chocolate Refiner at around $250 and 1 kg capacity is best for beginners and recipe testing. The Spectra 11 at around $479 and 9 lbs capacity is best for regular home production. CocoaTown 30-kilo models are for small commercial operations. All three use the same granite-on-granite mechanism and can reach the 10 to 20 micron particle size range that defines smooth chocolate — the difference is batch size, price, and the practical considerations at each scale.
The Mechanism All Three Share
Every melanger adapted from the Indian wet grinder design works the same way: two heavy granite rollers rotate on a flat granite base plate inside a stainless steel drum. As the drum rotates, material is dragged under the rollers, where the combination of compression and shear force reduces particle size. No blade is involved. The process is purely mechanical pressure.
This mechanism does two things simultaneously: it refines particles (reducing them toward the 10 to 20 micron target) and it conches (oxidizing volatile aromatics and distributing fat through the mass). For craft chocolate, having these two processes happen in the same machine during the same run is the core advantage of the melanger format.
The minimum viable refining time is 8 hours. Dandelion Chocolate recommends 18 to 24 hours total. Nanci at Chocolate Alchemy finds flavor peaks at approximately 8 hours, with an optimal balance around 30 hours and diminishing returns after that.
Premier Chocolate Refiner
Capacity: Approximately 1 kg Price: Approximately $250 Best for: Beginners, recipe testing, occasional use
The Premier is Dandelion Chocolate’s entry-level recommendation. At 1 kg capacity and $250, it is the lowest barrier to getting into genuine stone grinding.
The Premier’s small drum makes it physically easy to work with — cleaning is faster, loading and unloading is simpler, and the machine fits easily on a kitchen counter. For a maker who is testing multiple origins or formulations in parallel, running several Premier batches simultaneously at 1 kg each is a practical approach to comparative testing.
The practical limitation is throughput. One kilogram per batch with 18 to 24 hours per batch means that producing any meaningful quantity requires multiple machines or significant time investment. At the Premier’s scale, making 5 kg of finished chocolate takes at least five separate 24-hour runs.
Grain size consistency is comparable to the Spectra 11 — both reach 10 to 20 microns given adequate time. The Premier’s smaller drum means there is less total mass pressing down on the rollers, which may mean slightly longer refining times compared to the Spectra for very hard or large particles.
Spectra 11
Capacity: Approximately 9 lbs Price: Approximately $479 Best for: Regular home production, small-scale serious making
The Spectra 11 is the primary recommendation from Chocolate Alchemy for makers beyond the beginner stage. At 9 lbs capacity and $479, it offers meaningful production volume at a price that is still accessible for home use.
Nine pounds of chocolate mass per batch is a significant jump from 1 kg. A single Spectra 11 run can produce enough chocolate for dozens of bars. For a maker selling at farmers markets, gifting regularly, or making enough to justify weekly production runs, the Spectra 11 hits the right balance.
The larger drum means more thermal mass, which is relevant for long runs. The Spectra 11 maintains temperature better than the Premier over extended periods, which helps refining consistency. The tradeoff is that overflow is a more significant risk with the Spectra — nibs should be added gradually in the early stages when the mass is most fluid and the drum is fullest.
One practical note from experienced users: the Spectra 11 can be noisy at full load. Long refining runs (18 to 30 hours) run overnight; plan for this if your kitchen is near sleeping areas.
CocoaTown
Capacity: 9-liter (home range) to 30-kilo (production) Price: Varies significantly by size Best for: Small commercial operations, production scale
CocoaTown manufactures melangers across a wide capacity range. Their 30-kilo production models are the reference machines for small craft operations. Dandelion Chocolate’s Valencia Street production line ran six 30-kilo CocoaTown melangers 24 hours a day, seven days a week, producing approximately 12,000 bars per month. That is the clearest real-world benchmark for these machines.
CocoaTown also makes a 9-liter model that bridges the gap between the Spectra 11 and the production 30-kilo units. For a maker who has outgrown the Spectra but is not yet running 24/7 production, the 9-liter sits in the middle of that range.
The 30-kilo production models are a business decision. They require 24/7 operation to justify their cost. If you are not selling finished chocolate in volume, the economics do not work.
Head-to-Head Comparison
The most important variable across all three machines is the same: how long you run them. The Premier and Spectra 11 both reach 10 to 20 microns given adequate time. CocoaTown’s 30-kilo machines reach industrial particle size targets (18 to 25 microns D90) under continuous operation.
Cleanup is faster on the Premier because the drum and components are smaller. The Spectra 11 takes longer to clean, which matters if you are changing between different origin chocolates or chocolate types. CocoaTown production machines are typically dedicated to specific chocolate types and cleaned far less frequently.
Motor longevity: the Spectra 11 is commonly reported to run for years under weekly use without motor failure. The Premier is less frequently used for extended production; its motor life under intensive use is not as well documented. CocoaTown production machines are engineered for continuous commercial duty.
Which One Should You Buy?
Start with the Premier if you are making chocolate for the first time, testing recipes, or uncertain about your long-term commitment to the craft. The lower price and smaller batch size make it a forgiving starting point. You will not be disappointed by what it produces — it is the same mechanism as the Spectra, just smaller.
Move to the Spectra 11 when batch size has become your limiting factor. If you find yourself wishing you could run more than 1 kg at a time, or if you are making chocolate at least once a week, the Spectra 11 is the right upgrade. The jump from $250 to $479 is justified by the nearly 4× capacity increase.
Consider CocoaTown only when you are producing for commercial sale and need the 30-kilo scale or the 24/7 duty cycle. The 9-liter CocoaTown is a consideration if you have outgrown the Spectra but the 30-kilo is more than you need.

Frequently Asked Questions
- What is the main difference between the Premier and Spectra 11 melanger?
- Capacity and price are the primary differences. The Premier holds approximately 1 kg and costs around $250; the Spectra 11 holds approximately 9 lbs and costs around $479. Both use the same granite-on-granite mechanism and reach the same 10–20 micron particle size range. The Premier is for beginners and recipe testing; the Spectra 11 is for regular production use.
- How does CocoaTown compare to home melangers?
- CocoaTown's 30-kilo production models operate at a different scale than home melangers. Dandelion Chocolate ran six of them 24/7 to produce approximately 12,000 bars per month. They use the same stone-grinding mechanism but at a capacity and duty cycle designed for commercial production. Home use of a 30-kilo CocoaTown is not economical.
- Does a bigger melanger produce better chocolate?
- No. Particle size and flavor development depend on run time and mechanical consistency, not drum size. The Premier and Spectra 11 both produce the same 10–20 micron range given adequate time. A bigger machine produces more chocolate per run, but the quality per gram is the same as a smaller machine run for the same duration.
- How long does each melanger take to grind chocolate?
- All three machines take the same amount of time per batch because particle reduction rate depends on the mechanism, not the drum size. The minimum is 8 hours; 18–24 hours is the practical target; 30 hours is the optimal window identified by Chocolate Alchemy. The difference is that the Spectra 11 produces more chocolate at the end of that time.
- Can I run the Spectra 11 overnight?
- Yes, and most makers do. Long refining runs of 18–30 hours are standard, and running overnight avoids the noise of daytime operation. Ensure the machine is properly loaded (not overfilled), is sitting on a stable surface, and is not enclosed in a space that could trap heat. Check the machine after the first hour to ensure everything is running properly before leaving it unsupervised.
- Is the CocoaTown 9-liter worth buying over the Spectra 11?
- The CocoaTown 9-liter occupies a middle position between the Spectra 11 and the production 30-kilo. For most home makers, the Spectra 11 at approximately $479 provides sufficient capacity. The CocoaTown 9-liter becomes relevant if you have specifically outgrown the Spectra and are not yet at the scale where the 30-kilo production machine makes sense.
