Cocoa butter is essential as an ingredient as far as encapsulating the non-soluble particles, with insufficient fat, chocolate will not melt smoothly in the mouth. The ideal amount of fat is thus dictated by the particle size, smaller sizes 15-18 microns will require more butter to encapsulate due to a larger surface area. Even smaller sizes don't make sense as our tongues cannot identify particles beyond this range, and the chocolate will feel muddy.
Cocoa butter is priced between premium beans and commodity-grade beans. So for premium chocolates, quantity of cocoa butter will tend to be at least sufficient because it reduces cost to use cocoa butter. For commodity chocolates, cocoa butter may be insufficient if the producer wants to cut costs.

I've attached a file with info I've collected on the percent of cocoa butter and cocoa solids for some of the bars I've reviewed. I also give my rating of my enjoyment of these bars. In general, the bars with a higher fat content were lower on my enjoyment scale.
(If you're curious, "Class Rating" refers to a system I devised to compare similar type chocolates. Some of my "Classes" are Darks: <59%. 60s, 70s, 80s, 90s, 100%, White, Milk, Mint, Spices, Spicy Hot, Nuts, Nibs, Orange, Other... I did this as a way to compare bars of a similar group such as "White". This allows me to know which bars I liked best in a certain group even if I don't particularly like that kind of chocolate. "White" is a good example because I don't particularly like White chocolate but there are some bars I gave a White class rating of 10 because if I have a whim for a White bar then that's one I enjoyed the most. I hope this makes sense.)

I'm moving some info over from another thread because I think this is better home for it:
Lowe:
In my experience, the general practice seems to be that the higher the overall percentage, the higher the relative percentage of cocoa butter (without increasing the cocoa solids much).
[My guess on why they do this is it that this it's for economic reasons. That assumes that cocoa butter is cheaper than solids.]
Clay's reply:
Lowe:
Some terminology because I know you love this stuff.
What we think of as cocoa powder is what the industry technically calls "non-fat cocoa solids." Cocoa butter is also cocoa solids - so it's good to be careful in differentiating between the two when the goal is to be accurate and precise.
Cocoa powder almost always contains cocoa butter. A "high-fat" cocoa powder will consist of 20-24% fat by weight; a "low-fat" cocoa powder will consist of 10-12% fat by weight. It's really expensive (in part because it's time consuming) to go much lower than this. Cocoa powders making "non-fat" claims can do this because of labeling regulations that allow "non-fat" claims when the amount is below a certain threshold per serving (usually less than 1/2 gram).
FYI generally, cocoa butter is generally more expensive than cocoa powder- often much more expensive.
By Lowe:
Clay,
Thanks. Using the most precise language possible helps to avoid confusion, so I'm all for using the most accurate terms possible.
Unfortunately, many people aren't that precise or use terms in the wrong way. I think I took my use of these terms from an article in The Nibble : "Cocoa butter is the natural vegetable fat present in the cacao bean. Beans are approximately 52% cocoa butter by weight (the amount varies by the variety of cacao bean ); the rest is cocoa solids"
My line of inquiry started with wondering if there was any correlation between fat content and my enjoyment level (designated by my rating). Thus far I haven't really found out any such correlation, but I still want to differentiate them. So overall a cacao bean has fat and non-fat. I'm trying to be even more precise than cocoa powder since that also has some fat in it. For example, the Mast Bros and Rogue Piura bars that I'm currently reviewing only list cacao/cocoa beans and sugar as their only ingredients. What are the best terms for the 2 components of the beans? How about "cacao fat" or just "fat" for one? What is the other part? Solids, powder, liquor, or mass all seem problematic since they actually have some fat. Is there any term for the non-fat part? It sounds like "non-fat cocoa solids" may be the closest even if that contains some fat.
BTW, I've also been using "cocoa butter" as synonymous with "cacao fat" although I guess they're not really identical. I assume that all of the fat is in the cocoa butter, but that cocoa butter has more than just fat. Is that accurate?
Thanks for your patient help with splitting hairs in this minutia.
From Clay " FYI generally, cocoa butter is generally more expensive than cocoa powder- often much more expensive ."
So why do think there's generally higher fat content in higher percentage bars? By adding extra cocoa butter the makers are decreasing their profit margin. It doesn't seem like it's for taste because IMO extra cocoa butter weakens the taste. But maybe the makers just think most people couldn't handle that much "non-fat cocoa solids". What's your opinion?

Is there anything other than fat in cocoa butter? Or is cocoa butter 100% fat?
Here's information I got from The Nibble : Cocoa butter is the natural vegetable fat present in the cacao bean... It solidifies into a yellowish-white fat, solid at room temperature." Is this completely accurate?

Lowe, in the linked thread about migraines, Clay said that "Cocoa butter has more than fat in it in the same way that butter has more than fat in it".
This is incorrect. Minifie, Beckett, and the USFDA all agree that the term "cocoa butter" means the _edible fat_ obtained from cocoa beans.
It might be difficult (or even practically impossible) to remove 100% of the non-fat compounds from cocoa butter, but that just means that your cocoa butter is "contaminated" with other compounds. It doesn't mean that cocoa butter isn't pure fat.
By contrast, "butter" in the more common sense of the word refers to a dairy product made from cream. The butter in my fridge is only 81% fat (most of the rest is water). Dairy butter also naturally contains a small percentage of protein and carbohydrates.
Also, Lowe, I've taken a look at the file on your website labelled "Cocoa Fat in Chocolate", and I have a couple of questions and suggestions.
First of all, it would be helpful for the columns to include clear unit measurements.
For example, what exactly does "Percent" indicate? And how about "Cacao fat"?
The lack of clear explanation of these terms makes the data confusing. For example, I don't know what you mean when you state that Green & Black's white chocolate is:
Percent: 30
Cacao fat: 47
Non-fat solids: 0
If the bar is 30% cocoa solids, and 100% of the cocoa solids is cocoa butter, then how did you arrive at the 47% figure? The only way that figure makes sense to me is if you've included milk fat in the "Cacao fat" column.
Also, you asked: "So why do think there's generally higher fat content in higher percentage bars? By adding extra cocoa butter the makers are decreasing their profit margin."
1. You can't simply assume that "higher fat" means "added cocoa butter" (for example, many bars also contain milk fat, and/or other vegetable fats, e.g. Green & Black's white chocolate, as mentioned above).
2. A bar with a higher percentage of cocoa solids would naturally contain a higher percentage of cocoa butter, if expressed as a _percentage of the total bar_ (this is because pure cocoa liquor is always roughly 55% cocoa butter - hence, the more cocoa liquor you use, the more cocoa butter comes along for the ride).
So, an 80% bar with no added cocoa butter would contain about 44% cocoa butter, while a 60% bar with no added cocoa butter would contain only about 33% cocoa butter.
3. Cocoa butter isn't necessarily a more expensive ingredient than cocoa liquor. For example, if you produce your own cocoa liquor on a relatively small scale from whole beans, you can probably purchase cocoa butter from a large manufacturer for a fraction of the price that it costs you to produce your own cocoa liquor.
4. A lot of people (women especially, I've noticed) prefer the taste and mouthfeel of chocolate with a generous amount of added cocoa butter - so it sells very well in certain demographics.

Thanks so much for that long and very informative reply.
What do you call the part of the cacao seed that isn't fat?
More to reply to, but I'll start with that.

From Langdon "what exactly does "Percent" indicate? And how about "Cacao fat"?"
Percent = the percentage of all cacao that is printed on the label
Fat = from the nutrition facts. Calculated from Fat grams / serving size and changed from a decimal to a percentage. e.g.- 14 g fat in a 40 g serving = o.35 or 35% fat
I'll try to explain somewhere where these numbers come from. Thanks for the advice.

Green & Black's White was a mistake that shouldn't have been in there. That was done early in my data collection process and has now been removed, as will any other White bars. White can't be included because of the other added fats. Thanks for pointing that out. Please let me know of any other discrepancies or errors.

Langdon:
Technically true, Minifie et al and the USDA refer to the edible fat component. However,I am not aware of any commercially available cocoa butter that is not "contaminated" (in the sense that you use the word) by at least some amount of volatile aromatics. I was making the point with references to Lowe's impression that adding cocoa butter muted the flavor of chocolate - I was pointing out that cocoa butter does have flavor. I may not have chosen the clearest way to express that thought.

Even so, Clay, x amount of cocoa butter has much less flavour than the same amount of cocoa liquor. So it's fair to say, as Lowe did, that extra cocoa butter weakens the flavour.
In some bars, where only a small amount of cocoa butter is added, the weakening effect might be negligible, but in other bars (like Choklat 70%, for example, which contains 30% added cocoa butter) the effect is undoubtedly significant, whether the cocoa butter is deodorized or not.
Also, much chocolate is made with deodorized cocoa butter anyway - e.g. milk and white chocolates.
It also seems safe to assume that origin bars would often contain deodorized cocoa butter, too - because no serious chocolate maker would want the flavour of their "Chuao" (or whatever) beans competing with flavourful cocoa butter from a completely different origin (very few artisan manufacturers press their own cocoa butter).

Langdon:
I wasn't arguing the amount or intensity of the flavor of a cocoa butter, just that cocoa butter has flavor. I agree that the affect adding a deodorized cocoa butter has on the flavor of a chocolate depends on how "flavorful" the chocolate was to begin with and how much cocoa butter gets added.
You are right, few origin chocolate bars contain undeodorized cocoa butter made from the same beans as the liquor. The only origin chocolate maker in the US that I know of that has a butter press is Askinosie.
FWIW, it's my opinion that in order to be truly called a "single" origin chocolate it's necessary to use butter from beans of the same origin (deodorized or no), not butter from an unknown source. If the chocolate maker is making a single-plantation bar, then the butter needs to be from beans from the same plantation, not the same region or country, in order to be a "true" "single-origin."

Forgive me for misunderstanding, Clay, because I thought that was precisely what you meant when you said here that "If the cocoa butter is pressed from the same beans that the chocolate is made from and the butter is not deodorized then the flavor isn't diluted."

"So why do think there's generally higher fat content in higher percentage bars? By adding extra cocoa butter the makers are decreasing their profit margin. It doesn't seem like it's for taste because IMO extra cocoa butter weakens the taste."
IMO, whether the cocoa butter is deodorized or not, I think each manufacturer uses whichever to achieve the flavor they wanted.
It may be true that cacao powder is more flavorful than cocoa butter, but I think chocolate is not just about "chocolatey" flavour burst.
The notes, the mouthfeel, and the aroma might be enhanced or muffled by the ingredient they use.
Too much cocoa powder might overpower the taste details and notes of flavor. That may be one of the reasons why they decided to use cocoa butter instead of powder.
CMIIW.
I wouldn't be surprised if makers add cocoa butter solely to appeal to a certain clientele, namely those who favor texture over flavor andto ease the transition into higher percentages for those folks who are just tooreticent of going that route. chocolate can have a fantastic texture withoutoverloading the fat content with cocoa butter or vegetable oils or other"texture-enhancers." Particle size achieved through the grinding andrefining has much to do with the finished texture. A rough estimate of 50% iseven easier to calculate. I forget which beans have more fat but I think it isforastero from Ghana.At least I remember that the butter content in those beans is supposed to beharder, which makes them more suitable for milk.

So, I used the method above and calculated the cocoa butter percentages for more than 300 bars... then I discovered that method was flawed, so I threw away all of that data. I had neglected the fact that the serving size was the total weight of cacao plus sugar plus any extra ingredients (vanilla and/or soy lecithin)
Here is the correct method:
1) Note the serving size (in g)
2) Calculate the amount of cacao per serving by using the cacao percentage. Keep in mind that the total serving size = cacao + sugar + (optional other ingredients, 1-2%).
The amount of cacao = serving size X cacao percentage (as a decimal number).
Ex- a 40 g serving X .75 = 30 g cacao.
3) Note the Total Fat (in g)
4) Divide Total Fat by Cacao Amount in step 2. This gives you a decimal. Then convert this decimal number to a percentage (i.e. 0.52 is 52%) and then you have the cocoa butter percentage.
An example, Fresco Dominican Republic 223, 72%:
1) Serving size = 45 g
2) Cacao percentage = .72
3) Weight of cacao = 45 x .72 = 32.4
4) Fat content = 16.2 g
5) 16.2/32.4 = .50, so 50% cocoa butter
ChocoFiles-
I think that you are incorrect not in the mathematics but in the assumptions. Let me follow your example with a lower % bar
Dagoba 37%:
1. 56g total wt
2. 20g fat wt / 21g cacao wt
3. 36% fat
4. 37%-36% = 1% or 97% butter
I can show you many more examples like this. In fact some 30% bars have a negative cacao %.
I am a chemical engineer and I did all of this before I posted my first thread-- which included my assumptions on what cacao% means. I also attached a rough spreadsheet which calculated weight percentages of each constituent. I believe that the OP incorrectly assumes that %cacao is without fat. I made a bold assumption on the fat% and when entered into my spreadsheet shows a wide variation of dry cacao and a very low variation on fat% which makes sense to me. It shows that the texture is well agreed upon and the % cacao is inversely related to sugar based on personal taste preference.

Drew,
Thanks for the reply but I think you missed a crucial point that wasn't made clearly enough in my OP. You can only do this with dark chocolate that has no other inclusions such as milk powder, fruit, nibs, or nuts added.
The only 37% bars I have ever seen are milk chocolate bars, so they have milk powder and other ingredients added, including some that have fat in them. You CANNOT use this method with any bars that have inclusions. Does that make sense?
A better explanation is below:
---
Its actually pretty easy to figure out the percentage of cocoa butter in a chocolate bar. Note, though, that you can only do this with dark chocolate that has no other inclusions such as milk powder, fruit, nibs, or nuts added. You also have to have a package with the nutritional information that includes the fat content (in grams) because the fat is from cocoa butter. Follow these steps:
1) Note the serving size (in g)
2) Calculate the amount of cacao per serving by using the cacao percentage. Keep in mind that the total serving size = cacao + sugar + (optional other ingredients, 1-2%).
The amount of cacao = serving size X cacao percentage (as a decimal number).
Ex- a 40 g serving X .75 = 30 g cacao.
3) Note the Total Fat (in g)
4) Divide Total Fat by Cacao Amount in step 2. This gives you a decimal. Then convert this decimal number to a percentage (i.e. 0.52 is 52%) and then you have the cocoa butter percentage.
An example, Fresco Dominican Republic 223, 72%:
1) Serving size = 45 g
2) Cacao percentage = .72
3) Weight of cacao = 45 x .72 = 32.4
4) Fat content = 16.2 g
5) 16.2/32.4 = .50, so 50% cocoa butter

Also, in your example you have "1. 56g total wt". But the nutritional information is based on a serving size. For Dagoba bars the whole bar is usually 56g but the serving size may only be half of that. Was your example using Serving Size from the nutritional info or the total size of the bar?

For what its worth, you can often find 'specification sheets' for callebaut products online. Just search for "product name specification".
The spec sheet will often include both the % cocoa mass and the % non-fat cocoa solids.
You can use these spec sheets to double check your calculation technique for 'extracting' the relevant info from ordinary nutrition information.
Finally, several of the Callebaut dark chocolates are made with cocoa mass, defatted cocoa powder, sugar, vanilla, lecithin. These are not high end single origin chocolates, rather middle of the road mass market ingredients. These chocolates are very, very thick when melted and have relatively poor texture, but are quite nice for doing things like make ganache where the extra flavor hit per unit fat is a benefit.

Hi Sebastian,
I understand that by NIR you mean Near Infrared Transmission Spectroscopy.
I need to set up a lab which will be able to do reasonably accurate (no more accurate than +/- 0.5%) measurements of cocoa butter content in cocoa mass.
We use blends of in house processed beans in our recipes and I need to adjust mixer contents to variation of cocoa butter in the beans to improve chocolate consistency. I have just started to look around for solutions and uncle Google shows this:
Would you have an opinion on which method would work better?

Lots of pros and cons here. A few highlights to consider:
NMR and NIR will be be expensive instruments to acquire ($50-90k?).
NMR can be heavily influenced by metals content - so your process becomes very important. IE if you have a ball/attritor mill, the media will abrade off small pieces of metal and will impact your results.
NIR is heavily matrix and temperature dependent - you'll need to have a robust calibration curve for accuracy. Actually that's true with NMR as well.
If you have the funds to spend, and the expertise to create and maintain a calibration curve - i prefer the NIR, as you can calibrate it to predict other things as well. I've never used Oxford instruments specifically, but that they indicate in their literature that you only need 2 calibration points would concern the hell out of me.
A 3rd option is gravimetric extraction. Grinding your sample up, extracting the lipids with a solved, evaporating the solvent, and measuring what's left behind. Far less expensive up front costs, but you are now dealing with a solvent, and the consistency of the tech doing the prep work is important.

Sorry - one more thing that's relevant - how many/how often do you expect to do this testing? If it's once a day, i'd say go gravimetric. You'll need gravimetric to validate the calibration curves of the instruments anyway. If you need to run 5 samples every hour - than you'd need a small army of tech to prepare the samples, and an instrument's your way to go.
Hi Sebastian,
Thank you for your opinion.
I will need to do about about 3 on average and a maximum of 7 test per day, over 2 shifts so I may start with gravimetric and if this takes too much time buy the instruments. Based on your point about impact of metal content on results NIR looks like a better option.
Peter

Remember that NIR is VERY matrix dependent (and temperature dependent). Be sure you have a calibration curve for each type of chocolate that you're plan to run (ie, a generic 'milk chocolate' calibration won't be very accurate for all milk chocolates, and certainly not for dark or white chocolates). Run all your samples at a fixed temperature (including the plate the samples will sit on - probably easiest to get a small warming oven and set it to 50C and just keep everything inside of it).
good luck!

Spectral Engines has a new NIR instrument: http://www.spectralengines.com/applications/food-composition that has some interesting (at least to me) aspects.
Unity Scientific also has an NIR instrument - but importantly it has databases of characterized samples that could serve as baseline measurements. I think the machine is under $30k.

The name of the game here is to be sure to try it on your chocolate before buying. Everyone's pushing online calibrations (ie it reads your sample, and adds it to it's baseline calibration file with the argument that it makes everyone's stronger). Because of the high matrix sensitivity of NIR, "Jimmys" calibration curve doesn't mean anything really to "Johnnys" actual chocolate - as Jimmy has different process, raw material sourcing, and formulation than Johnny does.
Their argument is sort of a 'wisdom of crowds' argument applied to calibration. It just doesn't work that well i'm afraid. if you've got a very similar type of chocolate and process it works fantastically well (in fact i've built networks of matrixed NIR nodes all around the world to do just that) - but as a general 'catch all' for anything chocolate - not so much.

TheChocolateLife celebrates its 9th anniversary this week, starting publication the week of January 18, 2008. Already planning a 10th Anniversary bash!
Food and Wine Magazine's list of top chocolates in the US.
This appears to have been put together by a committee (there is no byline) and by people who have little or no understanding of the chocolate business. Like most lists produced this way, it's very uneven - mixing very small producers with global mass-market brands, and not differentiation between chocolate makers and confectioners.
What are your thoughts?
This year 2016 was a good year for our small business in Belgium. We now are following some new (for us) small and unique chocolate makers. Such as: Ananda (Ecuador), The Wellington chocolate Factory, Acali, Potamac, Letterpress, PumpStreet Bakery, Dick Taylor and La Naya. We are proud to be the smallest chocolate shop in Belgium following some of the best chocolate makers in the world.
Wishing you all a Merry Christmas and a happy New Year 2016/2017
