Dark chocolate

Cocoa solids, cocoa butter and sugar, with no milk solids. The percentage on the front adds those first two together and says nothing about their ratio.

What it is

Dark chocolate is the simplest composition in the category: cocoa mass, usually extra cocoa butter, sugar, and often a little lecithin and vanilla. What it does not contain is milk solids, and that single absence is what separates it from milk chocolate legally and sensorially — milk proteins blunt bitterness and astringency, so removing them leaves the bean audible.

The practical consequence is that dark chocolate is where origin and processing show. A milk bar at 35% can be made from indifferent bulk beans and taste perfectly pleasant; the milk and sugar are doing most of the work. A 75% bar has nowhere to hide, which is why almost all single-origin and bean-to-bar production is dark.

What the percentage means here

The percentage is the combined mass of everything that came from the cacao bean — cocoa solids plus cocoa butter — as a share of the finished bar. The remainder is almost entirely sugar. Crucially, it does NOT say how that total splits between solids and butter, and two 70% bars can differ by ten percentage points of cocoa butter. That is why one 70% bar tastes rich and one tastes harsh, and why a higher number is not a better bar.

Legal minimums

These differ by jurisdiction, and the difference is real rather than technical: the same words on a wrapper describe different products either side of the Atlantic.

  • European Union: The EU instrument reserves the plain name 'chocolate' for products meeting this floor, with separate minimums for cocoa butter and for dry non-fat cocoa solids within it.
  • United States: The US standards define 'sweet chocolate', 'semisweet chocolate' and 'bittersweet chocolate' separately, with the latter two sharing a floor. 'Dark chocolate' is not itself a standardised name in the US.

How it tastes

Ranges further than any other type. A Madagascan 70% can read as red fruit and citrus; a Ghanaian 70% as straightforwardly cocoa-ish and mildly bitter; a well-made 100% as earthy and surprisingly sweet-edged despite containing no sugar at all.

Working with it

Melts and tempers predictably, and is the default for moulding, enrobing and ganache. Above about 80% the low sugar and high solids content makes it grainier in a ganache and more prone to splitting, so higher-percentage bars generally need more liquid rather than less.

Commonly misunderstood

That a higher percentage means better chocolate, or more antioxidants per unit of enjoyment. It means less sugar and more cacao, which is a statement about proportion, not quality. Poorly fermented beans at 85% are simply more of a bad thing.

Market position

A minority of global chocolate consumption by volume and the majority of the speciality and craft segment.

Why two bars at the same percentage taste different

Three variables move independently of the number on the front: which beans, how they were fermented, and how the maker split the percentage between cocoa solids and added cocoa butter. The third is invisible on the label and is often the largest single influence on mouthfeel. A maker chasing a silky melt adds cocoa butter, which raises the percentage while making the bar taste milder — the opposite of what the number implies.

The 100% case

Chocolate with no added sugar is not a more intense version of a 70% bar; it is a different eating experience, and it is the clearest test of the beans. Nothing masks under-fermentation, over-roasting or poor conching. Readers who find it inedible are usually meeting a fault rather than a preference.

Pairs with

  • WhiskyOne of the most reliable pairings available, because whisky brings no tannin to clash with the chocolate's.
  • WineAuthored deliberately despite being the least reliable pairing in the catalogue: readers arrive expecting it, and the page's job is to explain why the standard version usually fails.
  • CoffeeA roast-forward dark chocolate at 65–75% meets a medium-roast coffee on equal terms without either being erased.
  • TeaSmoky and roasted teas meet dark chocolate's bitterness with a different kind of intensity rather than the same one, so the two sit side by side instead of competing.
  • RumAged rum's molasses and vanilla sit directly alongside dark chocolate's roast character, and the rum's residual sweetness keeps the chocolate from reading as bitter.
  • CheeseThe crystalline saltiness of a long-aged hard cheese cuts dark chocolate's bitterness and its nuttiness meets the chocolate's roast notes.
  • FruitOrange's acidity and aromatic oils cut dark chocolate's fat, and the combination is old enough to be a fixed confectionery category in its own right.
  • NutsSalted almonds against high-percentage dark: the salt suppresses bitterness and the nut's own fat softens the chocolate's edge.
  • DessertsHigh-percentage dark supplies bitterness that keeps a rich dessert from cloying, which is why it is the default for mousse, tart and torte.
  • SpicesChilli with cacao is the original combination, attested in Mesoamerican preparation long before sugar reached the drink.
  • BeerRoasted barley in a stout or porter meets dark chocolate's roast character directly, and the beer's residual sweetness keeps the chocolate from reading as bitter.
  • CocktailsA stirred, spirit-forward, lightly bittered drink has the weight to stand next to dark chocolate and none of the acidity that would fight it.
  • BerriesWorks well with a round, low-acid dark chocolate where the berry supplies the brightness the bar does not have.
  • CitrusOrange peel oil dissolves into the cocoa butter and its acidity cuts the fat, which is why the combination has been a fixed confectionery category for over a century.
  • BreadA piece of dark chocolate in plain bread is a long-standing Spanish and French merienda, and the bread's salt is doing exactly what a pinch of salt does to any sweet thing.
  • SaltSalt suppresses the bitterness that limits how much high-percentage dark chocolate most people enjoy, which makes an 80% bar considerably more approachable.
  • EspressoA roast-forward 70% dark meets espresso's intensity without either erasing the other.
  • Black teaA malty Assam or a Ceylon with a 65–70% dark works if the tea is brewed short enough to keep its tannin in check.
  • OolongA roasted oolong's toasted character meets dark chocolate's roast notes directly, and the tea's low tannin avoids the red-wine problem.
  • Red wineOnly works with a low-percentage, low-acid dark and the fruitiest, softest red available. Most combinations in this space disappoint.
  • Port and fortified wineRuby or LBV port carries the residual sugar to survive a 70% bar and the fruit concentration to be tasted through the cocoa butter.
  • Milk and creamMilk proteins bind the polyphenols responsible for astringency, which makes a high-percentage bar considerably more approachable.
  • StrawberryDark chocolate's bitterness against the strawberry's sweetness is the most familiar version of the pairing, and it works.
  • RaspberryWorks well with a low-acid dark — a Venezuelan or Ghanaian bar — where the raspberry supplies the brightness the chocolate lacks.
  • OrangeOrange peel oil dissolves into the cocoa butter and its acidity cuts the fat. The combination has been a fixed confectionery category for over a century.
  • BananaDark chocolate supplies the bitterness that a banana pairing otherwise lacks, which stops the combination cloying.
  • AlmondSalted roasted almond against a high-percentage dark: the salt suppresses bitterness and the nut fat softens the edge.
  • Sea saltSalt suppresses the bitterness that limits how much high-percentage dark most people enjoy, which makes an 80% bar considerably more approachable.
  • ChilliThe original combination, attested in Mesoamerican preparation long before sugar reached the drink.
  • Aged hard cheeseThe crystalline saltiness of a long-aged hard cheese cuts dark chocolate's bitterness and its nuttiness meets the roast notes.
  • Olive oilThe oil's peppery polyphenol bite reads as a green lift alongside cocoa's bitterness rather than adding to it.
  • BourbonBourbon's sweetness offsets dark chocolate's bitterness, and its rye spice adds a dimension the chocolate does not have.
  • Peated whiskyPeat smoke and cocoa's earthiness occupy different parts of the palate, so each stays distinct while the fat softens the smoke.
  • Stout and porterRoasted barley and roasted cacao share a Maillard-derived register, and the beer's residual sweetness keeps the chocolate from reading bitter.
  • CoconutToasted coconut brings roast character and its own fat, both of which integrate with dark chocolate rather than sitting against it.
  • MintDark chocolate has enough bitterness and body to remain audible under menthol's cooling effect.
  • CaramelDark chocolate's bitterness gives the caramel's sweetness something to work against, which is why dark salted caramel works so consistently.
  • Dried fruitLong-fermented dark chocolate carries its own dried-fruit character, so this is a matched pairing as well as a sweetening one.
  • ButterSalted butter's salt suppresses bitterness and its dairy notes fill in what dark chocolate has none of.
  • Ice creamWarm dark chocolate sauce over cold ice cream gives both the temperature contrast and enough aromatic release to taste of chocolate.
  • Sourdough and rye breadRye's malty bitterness meets dark chocolate's roast notes, and sourdough's acidity cuts the fat.

Commonly confused with

  • Baking chocolate'Baking chocolate' means unsweetened chocolate in North America and ordinary sweetened dark in much of Europe, and recipes rarely say which they assume.
  • Unsweetened chocolateSubstituting one for the other changes the recipe by the entire sugar content of the chocolate — roughly 45g per 100g against a 55% bar.

Can substitute for

  • CouvertureInterchangeable in ganache and in baking. Not interchangeable for coating or moulding, where couverture's cocoa butter content is the whole point.
  • Semisweet chocolateInterchangeable with a modest sugar adjustment. The gap between an American semisweet at around 58% and a European 70% bar is roughly twelve percentage points of sugar.

Techniques that work with this

  • Making ganacheThe 2:1 ratio is calibrated for dark chocolate, and using it with milk or white produces a ganache that will not set.
  • Tempering chocolateGetting cocoa butter to set in its stable crystal form, at home, without a machine. The physics is identical to the factory step; the equipment is not.
  • Melting chocolateThe most basic technique and the one with the two most common disasters: seizing from water, and scorching from heat.
  • Making hot chocolateTwo different drinks share the name. Which one you are making determines everything about how to make it.
  • Baking with chocolateSubstituting one chocolate for another changes the sugar, the fat and the liquid balance at once, which is why the substitution so often fails.
  • Chocolate sauceA pourable emulsion that stays pourable. Structurally a loose ganache, with the ratio pushed past where it would set.
  • Chocolate frostingThree quite different things share the name, and choosing between them is mostly about how it has to behave once piped.
  • Chocolate mousseAn aerated chocolate preparation, and the classic case where the chocolate's percentage determines the set rather than the recipe.
  • Handling and storing chocolateSteady 15–18°C, dry, wrapped, away from smells, and not in the fridge. Steadiness matters more than coolness.
  • Chocolate has seizedA small amount of water turned it into a stiff paste. It cannot be returned to melted chocolate — but adding much more liquid rescues it as something else.
  • Chocolate has overheatedGritty with a burnt smell. Unrecoverable, and it happens at far lower temperatures than most people expect.
  • Chocolate has bloomedSafe to eat, and the two kinds have different causes. Touch it: smooth and greasy is fat, rough and gritty is sugar.
  • Making trufflesSet ganache, shaped and coated. The ratio determines whether it can be rolled, and the ratio changes with the chocolate.
  • Traditional drinking chocolateThe thick European and Latin American styles. The texture comes from starch, not from more chocolate.
  • Infusing flavour into chocolateGetting flavour in without getting water in. Infuse the cream, use oil-based flavourings, or steep into the fat.
  • Chocolate glazeA pourable coating that sets glossy. Gelatine or glucose does the shine; the chocolate does the flavour.
  • Setting up a chocolate tastingFour bars, one variable, room temperature. The comparison teaches, not the individual bars.
  • Melting in a double boilerGentle, even, controllable — and the method most likely to introduce the one thing that ruins chocolate.
  • Melting chocolate in a microwaveFaster and safer than its reputation, provided you stop early — chocolate holds its shape long after it has melted.
  • Avoiding overheatingThree ceilings, one per chocolate type, and a change that cannot be undone once passed.
  • Tempering dark chocolateThe reference curve — 45–50°C, down to 27–28°C, back up to 31–32°C — and the most forgiving of the three.
  • Whipped ganacheA soft ganache cooled and then whipped to hold air. Lighter than ganache, more stable than mousse, and the ratio is the whole trick.
  • Baking with chopped chocolateThe opposite choice to chips: pools, seams and shards rather than discrete pieces. Usually the better-tasting one.
  • Choosing chocolate for a cakeCocoa powder for depth of flavour, melted chocolate for richness and density. Most good cakes use both.
  • Choosing chocolate for browniesThe bake where percentage matters most, because chocolate is a large share of the total mass.
  • Choosing chocolate for cookiesOne decision decides everything: pools or pieces. Chips hold their shape, chopped bar does not.
  • Choosing chocolate for drinksBody comes from cocoa butter, which is why powder-based drinks taste thin however much you use.
  • Scaling a chocolate recipeQuantities scale linearly. Times, temperatures and pan depths do not, and that is where scaled recipes fail.
  • Temperature controlSix numbers govern almost everything: three melting ceilings and three working windows. Most chocolate failures are one of them being missed.
  • Making chocolate curlsA temperature window a few degrees wide. Too cold and it shatters, too warm and it smears, and the bar in your hand is usually about right.
  • Making chocolate shavingsThe easier sibling of curls, and the one where cold chocolate is an advantage rather than a problem.
  • Making chocolate shardsThe best appearance-to-effort ratio in chocolate decoration. Spread thin, set, break.
  • Making mendiantsPiped discs with four toppings. The restraint is the technique — a fifth topping turns it into bark on a small disc.
  • Making chocolate clustersStir, spoon, set. The most forgiving confection there is, and the ratio of filling to chocolate is the only judgement.
  • Making chocolate caramelA sugar cook with chocolate added at the end. The temperature the caramel reaches decides whether it pours, chews or snaps.
  • Chocolate fondueA ganache thinned to stay fluid over heat. Not tempered, not meant to set, and it fails when treated as melted chocolate.
  • Chocolate tart fillingA ganache set in a pastry case. It needs to cut cleanly and stay soft in the mouth, which pulls the ratio in two directions.
  • Molten chocolate puddingsA deliberately under-baked sponge. The liquid centre is timing, not a separate sauce, and the margin is about a minute.
  • Chocolate ice creamNeeds more chocolate than seems reasonable, because cold suppresses aroma — and the fat makes it set harder than a vanilla base.
  • Preventing bloomTemper properly and store at a stable temperature. Stability matters more than the number.
  • Chocolate on a plated dessertThree temperatures on one plate is the point. Chocolate is the component most damaged by being served cold.
  • Using bloomed chocolateBloom is cosmetic. Melting removes it entirely, which makes bloomed chocolate perfectly good for anything that gets melted.
  • Chocolate work in hot climatesAbove about 26°C ambient, tempering is not viable and no technique changes that. What changes is what you make.
  • What equipment you actually needA probe thermometer and a bowl. Everything beyond that buys convenience rather than capability, with two exceptions.
  • Spanish drinking chocolateThick enough to coat a spoon, set with starch rather than with cream, and made to be dipped into rather than drunk.
  • Italian hot chocolateThickened, served in small volumes, and finished with cream on top rather than stirred through — a café product rather than a mug of cocoa.
  • Making nama chocolateA ganache set in a tray, cut cold into cubes and dusted — the simplest confection in this catalogue and the least forgiving about temperature.
  • Dairy-free ganacheReplacing cream means replacing fat and water in a fixed relationship — which is why plant milks fail and plant creams work.
