What Does Cacao Percentage Mean?
Cacao percentage is the total proportion, by weight, of all cacao bean derived ingredients in a bar, cacao mass, cocoa butter and sometimes cocoa powder combined. So, “70% cacao” does not necessarily mean “70% cocoa solids”. A higher percentage means more of the bar comes from cacao and less from sugar, though it says nothing about the ratio between those cacao bean derived ingredients themselves. Two bars can share the same percentage while differing significantly in the balance of cocoa solids to cocoa butter, which changes how each actually tastes. The number describes quantity, not the composition of that cacao content, and composition is not the same thing as quality.

A= Cane Sugar. C = Cocoa Nibs. B = Cocoa Butter.
How is the percentage actually calculated?
The percentage on a bar is a simple sum, by weight. Take every ingredient derived from the cacao bean itself, cacao mass, which naturally contains both cocoa solids and cocoa butter, any additional cocoa butter, and any cocoa powder, and add their combined weight together. Divide that total by the weight of the finished bar, sugar included, then multiply by 100.
So, a 100g bar labelled 70% cacao contains 70g of cacao-derived ingredients in total, and 30g of everything else, mostly sugar and sometimes a small amount of vanilla. Here’s what that 70g could actually comprise, using two genuinely different but equally valid ways of reaching the same number:
- Bar A: 65g cacao mass, 5g added cocoa butter, 30g sugar
- Bar B: 50g cacao mass, 20g added cocoa butter, 30g sugar
Both are correctly labelled 70% cacao. Neither is mislabelled, and neither is automatically the better bar. But Bar B contains considerably less cocoa solids for the same headline percentage, because more of its cacao-derived content is cocoa butter rather than cacao mass. That is one reason two 70% bars can taste noticeably different even though the wrapper says the same thing. See: Is Higher Cacao Percentage Better?
It’s something we research closely in our own recipe development at MayHawk. Our two-ingredient bars use only cocoa beans and cane sugar, while our flavoured bars balance in a small proportion of added cocoa butter alongside whatever else the recipe calls for.
What’s the difference between cacao percentage and cocoa solids?
The most confusing thing when reading the ingredient label on a chocolate bar is that cacao percentage and cocoa solids are related, but they are not the same thing. Mixing them up is one of the most common misreadings of a chocolate label.
Cacao percentage is the total of everything derived from the cacao bean, cacao mass, added cocoa butter and any cocoa powder combined. Cocoa solids are only the non-fat part of that cacao content: the material responsible for much of the colour and flavour of chocolate. Cocoa butter is not counted as a cocoa solid because it is the fat naturally present in the bean, separated from the cocoa solids during processing. Cocoa powder is different again. It is made from what remains once much of that cocoa butter has been removed, so it does count towards cocoa solids, but it carries a different flavour profile from cacao mass.
Going back to Bar A and Bar B from the section above, both were labelled 70% cacao, but their actual cocoa solids content differed considerably. Bar A, built mostly from cacao mass with only a small amount of added cocoa butter, has a cocoa solids figure much closer to its 70% headline number. Bar B, containing far more added cocoa butter, has noticeably fewer cocoa solids despite an identical percentage on the wrapper.
Under EU labelling law, some chocolate is required to state cocoa solids as a separate figure from the overall percentage, phrased on pack as “cocoa solids: …% minimum.” Where that second figure appears, it provides useful additional information because it tells you specifically how much of the bar consists of non-fat cocoa material, rather than the combined cacao-derived total represented by the headline percentage.
Why can cocoa powder be used to inflate the percentage cheaply?
This is a topic not much discussed, but one worth digging into. Cocoa powder is produced by pressing cocoa butter out of cacao mass, and it is generally less expensive to use than increasing the proportion of cacao mass or cocoa butter in a recipe. Part of that price difference comes down to demand elsewhere.
Cocoa butter is sought after beyond the chocolate sector. It is widely used in cosmetics and skincare, particularly in creams and balms, which helps keep its price higher regardless of what chocolate makers alone need. Cocoa powder has far less demand outside food and drink, keeping it comparatively inexpensive. Yet because cocoa powder still counts towards the total cacao percentage, as explained in the section above, a maker can use cocoa powder to increase the stated percentage without increasing the amount of cacao mass to the same degree.
The effect on the label is real. The effect on the chocolate is different. Taking a bar from 70% to 80% by adding cocoa powder does not necessarily deliver the same flavour, fat content or melt quality as a genuinely higher-cacao bar made with more cacao mass. The number goes up, but the number alone doesn’t tell you what has been added to achieve it.
Some cocoa powder is also alkalised, sometimes called Dutch-processed. This treatment darkens its colour and reduces its natural acidity, while also changing its flavour and reducing some of the naturally occurring polyphenols. It can produce a darker-looking, more mellow cocoa powder, which may affect the character and appearance of the finished chocolate. Non-alkalised cocoa powder, where powder is used at all, retains more of the characteristics of the original cacao. See: What Is Cocoa Powder?
None of this means a bar containing cocoa powder is automatically poor. It means the percentage alone cannot tell you whether cocoa powder is present, how much is being used, or what role it plays in the recipe.
Why do two bars at the same percentage taste different?
This has already been shown directly with Bar A and Bar B earlier on this page, and the same underlying answer explains much of the rest. The percentage is a combined figure, and the balance between cacao mass, added cocoa butter and any cocoa powder can vary considerably even when the total stays fixed. A bar containing more cacao mass relative to added fat and powder will generally taste more intensely of cocoa; a bar containing more added cocoa butter will generally taste smoother and milder despite having the same number on the wrapper.
Composition isn’t the only variable either. Origin, fermentation, roasting and conching all shape flavour independently of the percentage, which is why even two bars with genuinely identical composition can still taste different from one another, something we see clearly across our own single-origin range at MayHawk, where bars sitting at the same percentage carry noticeably different characters depending on where the cacao came from. Percentage tells you how much of the bar is cacao-derived. It says nothing about what was done with that cacao, or how well

How should I actually use the number when buying?
Treat the percentage on the packaging as a starting point, not a verdict on how dark or light the chocolate will taste. This number tells you roughly how much sugar to expect, and roughly how intense the cacao’s own flavour is likely to be, which is genuinely useful for matching a bar to personal taste. It tells you almost nothing about whether that cacao was any good.
A few checks matter more than the number on the front of the pack:
- Read the ingredients list, not just the percentage. A short list, cacao mass, cocoa butter, sugar, and little else, says more about a bar’s quality than a high percentage ever will on its own.
- See whether cocoa solids are stated separately. Where that second figure appears, it’s a more precise measure than the combined percentage, and worth comparing against it.
- Check where cocoa powder sits in the ingredients, if it’s used at all. Powder listed early, or in real quantity, on a bar also leaning on a high headline percentage, is worth a second look.
- Look for who made it and where the cacao came from. A named single origin and a named maker tell you far more about care and sourcing than any number can. See: What Is Craft Chocolate? for a good place to start.
None of this replaces trusting your own palate. But going in with these checks means the percentage stops being the only piece of information doing the work. Where a genuine starting point does help is knowing roughly what to look for by type of chocolate in the first place, which is exactly what the guide below sets out.
Guide: Which cocoa percentage is best for me?
There’s no single best cocoa percentage, it depends on how much you want the taste of cacao itself to lead, rather than sweetness and creaminess.
- Dark chocolate: A good dark chocolate, made with a short ingredient list, is sold from 60% to 100%. Our advice is to start at around 70%. At that level, the cocoa’s own flavour, fruit, spice, or floral notes depending on origin, comes through clearly without being overwhelmed by sugar. Moving up to 85% or 100% intensifies that character further, giving a bolder, more direct experience of the bean, though it also means less sugar to soften any sharpness in the cacao itself. See: What Is Dark Chocolate?
- Milk to dark-milk chocolate: For a good milk chocolate, look for 37% to 60% cocoa solids. Many milk chocolates on the market sit toward the lower end of that range, but 40% and above is where the cocoa genuinely starts to lead rather than the sugar, giving a noticeably more chocolatey flavour without losing the characteristic creaminess. From around 40% up to roughly 50%, the balance sits as classic milk chocolate, creamy and sweet with the cocoa clearly present. Above 50%, it moves into dark-milk chocolate, where the cacao’s own character becomes more pronounced while the milk keeps the texture smooth. See: What Is Milk Chocolate?
- White chocolate: Look for at least 35% cocoa butter, well above the 20% legal minimum. White chocolate contains no cocoa solids at all, so it never develops the traditional cocoa flavour that dark or milk chocolate carries. Its character depends heavily on the quality of the cocoa butter, alongside the milk, sugar and how the chocolate is made. Below 35%, there is simply less cocoa butter contributing to that character, and the balance can tip further towards tasting like sweetened milk rather than chocolate. See: What Is White Chocolate?
Does a higher percentage always mean a better bar? No, and this holds regardless of which type of chocolate is preferred. Percentage measures quantity, not quality, it says how much came from the cacao bean, not how well that cacao was grown, fermented, or made into chocolate. See: Is Higher Cacao Percentage Better?
