What Is Dark Chocolate?
Dark chocolate is chocolate made primarily from cocoa solids and cocoa butter, with sugar added for sweetness. It contains little or no milk or milk alternatives, allowing the character and dark colour of the cocoa to come through more clearly. While dark chocolate spans a broad range of cocoa percentages, a higher percentage does not necessarily mean it’s a better chocolate. The character and quality of dark chocolate depend on the cacao itself, its origin and variety, the other ingredients, and how it is processed and made. The often-cited rule of thumb of looking for 70% and above in a dark chocolate is a good starting point.
What Is Dark Chocolate In More Detail
Is there a legal minimum composition for dark chocolate?
Not all countries have a legal definition of dark chocolate, but in the UK and EU, chocolate must legally contain at least 35% total dry cocoa solids, including at least 18% cocoa butter and 14% non-fat cocoa solids, to be sold under a reserved chocolate description. That’s set out in EU Directive 2000/36/EC and implemented directly in UK law through the Cocoa and Chocolate Products Regulations. It’s worth knowing precisely because the percentage is probably lower than what most people actually mean by dark chocolate, the legal minimum and a person’s everyday expectation aren’t always the same thing. A higher figure, around 43% total dry cocoa solids, does exist in the European regulations, but it doesn’t apply to dark chocolate as a category on its own.
So if chocolate makers can legally call their chocolate “dark” at 35%, what percentage does the public actually expect? Most people expect dark chocolate to sit above 60% to 70%, some way above the legal minimum.
Why doesn’t a higher percentage mean better chocolate?
Because the percentage measures quantity, not quality. It tells you how much of the bar came from the cacao bean, not whether that cacao was well grown, well fermented, or well made into chocolate. Chocolate with a high cocoa content can still be made using cheap beans that have been rushed through the fermentation and drying phases, so you can get chocolate with a lower cocoa content that is far better in terms of flavour because it has been made with quality beans. Also, single-origin bars, at lower cacao percentages, often have unique and distinctive flavour notes, whereas bulk-bought beans, poorly processed, have very few. For the full explanation, see: Is Higher Cacao Percentage Better?
Can two chocolates with the same percentage taste different?
Yes, noticeably so. The percentage on the packaging is a combined figure, cocoa solids and cocoa butter together, and the balance between the two can vary even when the total stays the same. A 70% bar made mostly from cocoa solids will taste and feel quite different from a 70% bar carrying more added cocoa butter, even though the percentage on label reads identically. The higher-solids bar tends to be more intense and slightly more astringent, while the higher-butter bar is smoother and easier to eat. The number on the wrapper describes quantity, not composition. See: What Does Cacao Percentage Mean?
What does dark chocolate actually contain?
At its simplest, just cacao mass, cocoa butter, and sugar, sometimes with a small amount of vanilla. Cacao mass, also called cocoa mass or chocolate liquor, is the whole ground bean, both the cocoa solids and the cocoa butter it naturally contains, before any extra cocoa butter is added back in. Packaging doesn’t make this easy to follow. Some brands list “cocoa solids” on the front of pack, some list “cocoa mass,” and some craft makers simply write “cocoa beans,” and all three can be pointing at roughly the same underlying ingredient while sounding like three different things. They aren’t strictly interchangeable, and checking the full ingredients list, not just the headline percentage, is the only reliable way to see what’s actually inside a specific bar. Some dark chocolate also includes an emulsifier such as soya or sunflower lecithin, added to reduce production time, though it isn’t required in chocolate that has been properly conched. See: What Are Emulsifiers in Chocolate?
Is all dark chocolate the same?
No. Dark chocolate spans everything from mass-produced industrial bars to single-origin craft chocolate, and the term itself says nothing about which side of that line a bar sits on. See: What Is Craft Chocolate? and What Is Bean-to-Bar Chocolate?
Can Dark Chocolate Contain Dairy?
Yes, some dark chocolate can contain dairy. It’s often referred to as dark-milk chocolate, and it ranges from around 50% to 60% cacao and above. What matters is the balance between cocoa solids specifically, sometimes listed on packaging as cocoa mass or cocoa beans, and the cocoa butter, milk powder, and sugar making up the rest. If the cocoa solids are low but the cocoa butter and sugar are high, this is probably not a “dark chocolate” in the truest sense, since the darker, more bitter chocolate compounds come from the cocoa solids specifically.
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?
