Whether you're attending your first chocolate workshop, exploring single-origin chocolate bars, or simply curious about what goes into the chocolate you love, the language of chocolate can feel like a world of its own. This glossary demystifies the essential terms — from the cacao pod to the finished bar — so you can taste, talk, and think about chocolate with confidence.
A
Aztecs
Long before chocolate became a bar or a truffle, it was a drink — and the Aztecs were among its most devoted custodians. Building on the cacao traditions of earlier Mesoamerican civilisations, the Aztecs consumed xocolātl (from the Nahuatl words for "bitter" and "water") — a cold, frothy, often spiced drink made from ground cacao, water, chilli, and other ingredients. Cacao held profound cultural significance: beans were used as currency, offered to the gods, and consumed in ritual and ceremonial contexts. It was the Aztecs' cacao that Spanish conquistadors first encountered in the 16th century, setting in motion the journey that would eventually bring chocolate to Europe.
B
Bean to Bar
A term describing chocolate made by a single maker who controls the entire process — from sourcing raw cacao beans through to the finished bar. At York Cocoa Works, our bean-to-bar chocolate making process means we roast, winnow, refine, and temper everything in-house, giving us full control over flavour and quality.
Belgian Chocolate
A term widely used to denote quality, but one that is often misunderstood. Legally, "Belgian chocolate" simply means chocolate that has been processed and finished in Belgium — it says nothing about the origin of the cacao or the quality of the ingredients. Belgium has a long and distinguished tradition of chocolatiering, particularly in pralines and filled chocolates, and Belgian couverture manufacturers such as Callebaut and Belcolade are widely used by chocolatiers around the world. However, the label alone is not a guarantee of craft or quality — what matters far more is the cocoa content, the sourcing of the beans, and the skill of the maker.
Bloom
That greyish-white film or dusty surface you sometimes see on chocolate. There are two types: fat bloom, caused by cocoa butter migrating to the surface (often from poor tempering or temperature fluctuation), and sugar bloom, caused by moisture dissolving and recrystallising sugar on the surface. Bloomed chocolate is safe to eat — it just looks less appealing and may have a slightly different texture.
C
Cacao vs. Cocoa
Often used interchangeably, one is Spanish and the other an English translation. Cacao often is used to refer to the raw plant — Theobroma cacao — its pods, beans, and unprocessed derivatives. Cocoa is typically used to refer to the processed product: cocoa powder, cocoa butter, or cocoa mass. Some makers use "cacao" to signal minimal processing and higher quality, though there's no universal standard, what's most important is the form the material is in.
Chocolate
In everyday use, chocolate refers to the broad family of products made from cacao. Legally, however, the term is tightly defined. Under UK and EU regulations (derived from the EU Cocoa and Chocolate Products Directive 2000/36/EC, retained in UK law post-Brexit), chocolate must contain a minimum of 35% total cocoa solids, of which at least 18% must be cocoa butter and at least 14% must be dry non-fat cocoa solids. Products that fall below these thresholds cannot legally be labelled as chocolate. This legal definition exists to protect consumers and maintain quality standards — and it's why the cocoa percentage on a label matters more than many people realise. With a rise in fake chocolate from materials cultivated in laboratories it's an important distinction that keeps cocoa and the heart of chocolate.
Chocolate Maker
A Chocolate Maker is someone who crafts chocolate from cocoa beans, bringing raw materials together to create chocolate which is often known as Couverture.
Chocolatier
An artisan who works with Chocolate Couverture by tempering the chocolate to make truffles, bars and moulded pieces of chocolate. At York Cocoa Works our team of chocolate professionals are special because they are both Chocolate Makers and Chocolatiers, working with our own chocolate to craft our range of chocolate products.
Cocoa Solids
The collective term for all the components derived from the cacao bean — cocoa mass (also called cocoa liquor), cocoa butter, and dry non-fat cocoa solids (cocoa powder). When a chocolate label states a percentage — say, 70% — that figure refers to the total cocoa solids content: everything that came from the cacao bean, including both the fat (cocoa butter) and the non-fat solids. The remaining percentage is typically sugar, and in milk chocolate, milk solids. Understanding cocoa solids is key to reading a chocolate label accurately: a high percentage doesn't automatically mean better chocolate, but it does mean more cacao and less sugar.
Conching
A critical step in chocolate making where the chocolate mass is continuously mixed, heated and aerated over many hours — sometimes days. Conching develops flavour, reduces bitterness, and creates the smooth, flowing texture we associate with fine chocolate. The name comes from the shell-shaped (concha) vessels originally used. The duration and temperature of conching significantly affect the final flavour profile making each batch of chocolate unique.
Couverture
Chocolate with a cocoa butter content usually 31–38%, this makes it more fluid when melted, giving a thinner, glossier coating when used for enrobing or moulding by a chocolatier. Couverture must be tempered correctly to achieve its characteristic snap and sheen.
Criollo
One of the three main cacao varieties (alongside Forastero and Trinitario), Criollo is considered the most prized and complex in flavour — often described as nutty, fruity, and low in bitterness. It accounts for less than 5% of global cacao production, making it rare and sought-after by fine chocolate makers.
D
Dark Chocolate
Dark chocolate contains cocoa mass, cocoa butter, and sugar — no milk solids. The percentage on the label refers to the total cocoa content.
Direct Trade
A sourcing model in which a chocolate maker buys cacao directly from farmers or cooperatives, bypassing commodity brokers and intermediaries. Direct trade typically means higher prices paid to growers, greater transparency about origin and farming practices, and a closer relationship between maker and producer. Unlike Fairtrade, direct trade has no formal certification body — it relies on the maker's own commitment and transparency. For craft chocolate makers, direct trade is both an ethical stance and a quality decision: knowing your farmer means knowing your cacao.
Dutching (Dutch Processing)
A process where cocoa is treated with an alkalising agent to neutralise its natural acidity. This darkens the colour, mellows the flavour, and makes the cocoa more soluble — ideal for baking. The term comes from the first pressing process to remove the cocoa butter from the mass to enable the early chocolate makers like Rowntree to industrialise with their drinking chocolate as it was developed in The Netherlands. Dutching reduces the antioxidants naturally present in cacao. Natural (non-dutched) cocoa retains more of its original fruity, complex character.
E
Enrobing
The process of coating a centre (a truffle, caramel, or biscuit) in a layer of tempered chocolate. Enrobing can be done by hand-dipping or by passing centres through a curtain of flowing chocolate on a conveyor belt - almost like a chocolate waterfall. The quality of the temper determines the finish — a well-tempered enrobed product will be thin, and snap cleanly with a smooth finish.
F
Fermentation
One of the most important steps in cacao processing, happening at origin before the beans ever leave the farm. Freshly harvested cacao beans are piled and covered for 5–7 days, during which yeasts and bacteria break down the pulp and trigger chemical changes inside the bean. Fermentation is where much of chocolate's flavour potential is created — or lost. For craft chocolate makers poor fermentation cannot be corrected later in the process, however industrialised processes often standardise the complexities of the materials with high roasting techniques which makes these beans more bitter.
Fine Flavour Cacao
A designation used by the International Cocoa Organization (ICCO) to identify cacao varieties with exceptional aromatic complexity — as distinct from bulk commodity cacao. Fine flavour cacao typically includes Criollo, Trinitario, and certain Nacional varieties, and accounts for less than 8% of global production. Countries such as Ecuador, Madagascar, Peru, and Trinidad are recognised producers. Fine flavour cacao commands higher prices and is the foundation of craft and single-origin chocolate — it's the raw material that makes nuanced, terroir-driven chocolate possible.
Forastero
The most widely grown of the three main cacao varieties, accounting for around 80–90% of global production. Forastero beans are hardy, high-yielding, and disease-resistant, making them the backbone of the commercial chocolate industry. In flavour terms they tend to be robust and straightforward — strong cocoa character with less of the floral, fruity complexity found in Criollo or Trinitario. Not all Forastero is equal, however — the Nacional variety from Ecuador, technically a Forastero, is prized for its distinctive floral notes and is classified as fine flavour cacao.
G
Ganache
A smooth emulsion of chocolate and cream (and sometimes butter), used as a filling for truffles, a glaze for cakes, or a base for many confections. The ratio of chocolate to cream determines the texture — a higher chocolate ratio gives a firmer ganache suitable for rolling into truffles; a higher cream ratio gives a pourable glaze. Flavourings, spirits, and infusions can be added to create endless variations. Make sure you check out our recipe section for some of our ganache based truffle suggestions.
Gianduja
A smooth blend of chocolate and finely ground hazelnuts, originating in Turin, Italy. True gianduja uses a specific ratio of hazelnuts to chocolate and has a silky, melt-in-the-mouth texture. It's the ancestor of modern hazelnut chocolate spreads, though the original is far more refined and complex.
L
Lecithin
An emulsifier — usually derived from soy, sunflower or rapeseed — added to chocolate in small quantities, it improves the flow of the chocolate and reduce the amount of cocoa butter needed. It helps bind the fat and water-based components together. Many fine chocolate makers use minimal or no lecithin, preferring to achieve texture through conching and cocoa butter content alone. At York Cocoa Works we use Rapeseed Lecithin in our white and milk chocolate products only.
M
Mayans
The ancient Mesoamerican civilisation widely regarded as the first to cultivate cacao intentionally and develop it into a sophisticated drink. Archaeological evidence suggests the Maya were consuming cacao-based beverages as far back as 600 BCE. For the Maya, cacao was sacred — associated with the gods, used in religious ceremonies, and consumed at important life events. They prepared it as a frothy, often cold drink, sometimes mixed with maize, chilli, or flowers. The Maya's deep knowledge of cacao cultivation and preparation laid the foundations that the Aztecs would later build upon — and that ultimately led to the chocolate we know today.
Mélangeur
A stone grinder used in bean-to-bar chocolate making to refine and conch the chocolate mass simultaneously. Two heavy granite rollers rotate over a granite base, progressively grinding cacao nibs and sugar into smooth chocolate over many hours. The mélangeur is central to the craft chocolate movement — it's accessible, precise, and produces beautifully textured chocolate. At York Cocoa Works, our mélangeurs are at the heart of our chocolate making process, and you can see them in action on a Manufactory Tasting Journey, we affectionately call them Mary and Henry after the city's early chocolate makers.
Metate
A flat or slightly concave stone grinding surface used by Mesoamerican civilisations — including the Maya and Aztecs — to process cacao. It would often be shaped like a table, carved out of granite or lava that would sit over a fire to heat it from below. Roasted cacao beans were ground on the metate using a cylindrical stone roller called a mano, producing a rough paste of cocoa mass. The metate is one of the earliest tools in chocolate's history, and its principle — stone grinding cacao to release its fats and flavours — is directly ancestral to the modern mélangeur used in craft chocolate making today.
Milk Chocolate
A chocolate product made from cocoa mass, cocoa butter, sugar, and milk solids — typically in the form of milk powder, condensed milk, or cream powder. Under UK and EU regulations, milk chocolate must contain a minimum of 25% total cocoa solids and at least 14% milk solids. A higher-tier designation, milk chocolate with high milk content, requires at least 20% milk solids. The addition of milk gives milk chocolate its characteristic creaminess, balancing against the natural acidity of the cocoa beans. Milk chocolate is often lighter colour, and sweeter, more mellow flavour compared to dark chocolate. Quality varies enormously: the best milk chocolates balance cocoa complexity with dairy richness, while many commercial products rely heavily on sugar and vegetable fats to reduce cost.
Most milk chocolate recipes were developed competitively in Switzerland, where they were pioneering Milk Powder created by Henri Nestle, in the UK by Cadbury who tried to copy using liquid milk to create Chocolate Crumb, and by Hershey who stole an imitation recipe from Cadbury. These created very different techniques and tastes for chocolate that continue to styles that the Swiss, British and US chocolate makers and consumers still operate with today.
Molinillo
A traditional wooden whisk, hand-carved and turned, used to froth hot chocolate drinks in Mexican and Central American tradition. The molinillo is held between the palms and rolled rapidly back and forth to aerate the liquid, creating the thick, foamy head that was prized in pre-Columbian and colonial chocolate drinking culture. The Aztecs are said to have created froth by pouring liquid between vessels from a height — the molinillo refined this into an elegant tool. Today it remains a beautiful symbol of chocolate's living heritage.
Mouthfeel
The physical sensation of chocolate as it melts on the palate — distinct from flavour, but inseparable from the overall tasting experience. Good mouthfeel in chocolate is smooth, even, and progressive: no grittiness, no waxy coating, no abrupt finish. It is determined by particle size (achieved through refining), cocoa butter content, the presence of lecithin, and the quality of tempering. When tasting chocolate critically, mouthfeel is one of the key dimensions alongside aroma, flavour, and finish.
Moulding
The process of pouring tempered chocolate into shaped moulds to create bars, figures, or shells. The chocolate contracts slightly as it sets, making it easier to release from the mould. A well-tempered, well-moulded chocolate will have a glossy surface and a clean snap.
N
Nib
The inner fragments of the cacao bean, revealed after roasting and winnowing. Nibs are crunchy, intensely flavoured, and naturally bitter — they contain all the cocoa solids, including cocoa butter that will eventually become chocolate. They can be eaten as a snack, used in baking, or ground into cocoa mass.
O
Origin / Single Origin
Chocolate made from cacao sourced from a single country, region, or even a single farm. Like wine, the origin of cacao profoundly affects its flavour — Madagascan cacao tends to be bright and fruity; Ecuadorian can be floral and complex; Ghanaian is often rich and earthy. Single-origin chocolate celebrates these differences rather than blending them away.
P
Praline
In the Belgian and continental tradition, praline refers to a chocolate shell with a soft filling — what many people call a "chocolate". In the French tradition, praline (or praliné) is a paste made from caramelised nuts ground to a smooth, intensely flavoured cream. Context matters — and both are delicious.
Pressing
The process of separating cocoa butter from cocoa mass (also called cocoa liquor) under high hydraulic pressure. The result is two products: cocoa butter — the pure fat used in chocolate making and cosmetics — and the dry cocoa cake that is then ground into cocoa powder. Pressing is fundamental to the industrial chocolate process and was central to the Dutch innovations of the 19th century that made drinking chocolate more soluble and affordable. In craft chocolate making, the balance of cocoa butter in the final recipe is carefully managed to achieve the desired texture and mouthfeel.
R
Refining
The process of grinding the chocolate mass to reduce particle size until it becomes imperceptibly smooth on the palate. Chocolate is considered smooth when particles are below 20 microns — smaller than the tongue can detect. Refining is done using stone mills, steel rollers or fine balls, and the duration affects both texture and flavour development.
Roasting
One of the most transformative steps in chocolate making, roasting develops the complex flavours locked within the fermented cacao bean through the application of heat. Like coffee, the roast profile — temperature, duration, and airflow — profoundly shapes the final flavour: lighter roasts preserve more of the bean's fruity, floral character; darker roasts bring out deeper, more bitter, roasted notes. At York Cocoa Works, we roast our beans in-house, carefully calibrating each batch to bring out the best of each origin's unique character.
Rowntree's
One of York's most celebrated chocolate dynasties, founded by Henry Isaac Rowntree in 1862. The Rowntree family — Quakers with a strong social conscience — built not just a chocolate empire but a model village (New Earswick) and pioneered employee welfare long before it was fashionable. Their innovations include the development of cocoa essence and Elect Cocoa (early forms of drinking chocolate) and iconic products that remain household names. The Rowntree factory on Haxby Road shaped York's identity as a chocolate city for over a century. Their legacy is part of the story we carry forward at York Cocoa Works.
S
Snap
The clean, sharp sound and sensation when a piece of well-made chocolate is broken. Snap is a hallmark of correctly tempered chocolate — it indicates the presence of stable Form V cocoa butter crystals, which give the chocolate its firm, brittle structure at room temperature. A dull thud or a soft, bendy break suggests poor tempering or bloom. When tasting chocolate, snap is one of the first sensory cues — before aroma or flavour — that signals quality.
T
Tempering
The controlled process of heating, cooling, and reheating chocolate to encourage the formation of stable cocoa butter crystals (specifically Form V crystals). Properly tempered chocolate sets with a glossy surface, a satisfying snap, and a smooth melt. Untempered chocolate sets dull, soft, and streaky. Tempering is one of the most technically demanding skills in chocolate making — and one of the most satisfying to master.
Terroir
Borrowed from the wine world, terroir describes the environmental factors — soil, climate, altitude, rainfall, shade — that give cacao from a particular place its distinctive character. Two batches of the same cacao variety grown in different regions will taste markedly different. Terroir is why single-origin chocolate plays such an important role in sharing the story of cacao and chocolate and the work that is done to create it.
Terry's
Another pillar of York's chocolate heritage, Joseph Terry's confectionery business was established in York in 1767 by William Bayldon and Robert Berry; under the Terry family the company eventually grew into one of Britain's best-known chocolate manufacturers. Terry's of York became famous for products including the Chocolate Orange and All Gold, and their factory — the iconic Art Deco building on Bishopthorpe Road — remains a landmark of the city. Like Rowntree's, Terry's represents the extraordinary concentration of chocolate-making talent and ambition that made York a world centre for the industry. Understanding this history is part of understanding why York Cocoa Works exists.
Theobromine
The primary alkaloid in cacao, responsible for chocolate's mild stimulant effect and its characteristic slight bitterness. Unlike caffeine (which is also present in smaller quantities), theobromine has a gentler, longer-lasting effect. It's also the reason chocolate is toxic to dogs — their metabolism processes theobromine far more slowly than humans.
Theobroma Cacao
The botanical name for the cacao tree, from the Greek meaning "food of the gods" — a name that speaks to cacao's sacred status in Mesoamerican culture long before European botanists formalised it. Theobroma cacao is a tropical tree native to the Americas, growing within roughly 20 degrees of the equator. It produces large, colourful pods directly from its trunk and branches — a growth habit called cauliflory — each containing 20–50 seeds (the cacao beans) surrounded by sweet white pulp. The tree is the origin of everything: every bar, truffle, and cup of hot chocolate begins here.
Trinitario
A natural hybrid of Criollo and Forastero, originating in Trinidad in the 18th century after disease devastated the island's Criollo crop. Trinitario combines the hardiness and yield of Forastero with some of the aromatic complexity of Criollo, making it a prized variety for fine chocolate makers. It accounts for around 10–15% of global cacao production and is found across the Caribbean, Central America, and parts of Asia and Africa. Many of the world's most celebrated single-origin chocolates are made from Trinitario beans.
Truffle
A confection made from a ganache centre, typically rolled into a ball and coated in cocoa powder, tempered chocolate, or chopped nuts. Named for their resemblance to the rare and luxurious fungi, truffles are one of the most accessible and rewarding things to make in a chocolate workshop — and one of the most satisfying to eat.
W
White Chocolate
A confection made from cocoa butter, sugar, and milk solids — but containing no cocoa mass (cocoa solids). This is why white chocolate has no brown colour and a much milder, creamier flavour than dark or milk chocolate, and why some argue it doesn't qualify as "real" chocolate at all. Under UK and EU regulations, white chocolate must contain a minimum of 20% cocoa butter and at least 14% milk solids, with no more than 55% sugar. The quality of white chocolate depends heavily on the quality of the cocoa butter used — fine cocoa butter retains subtle floral and dairy notes, while deodorised cocoa butter produces a blander result. At York Cocoa Works, our white chocolate contains more cocoa than many commercial dark chocolates — a point of pride in how we approach every category.
Winnowing
The step after roasting where the outer shell (husk) of the cacao bean is cracked and separated from the inner nib using air flow. The lighter husks are blown away, leaving behind the nibs that will be ground into chocolate. At York Cocoa Works, you can see our winnower in action during a manufactory tour.
X
Xocolātl
The Nahuatl word — from the language of the Aztecs — from which the word "chocolate" is derived. Literally meaning "bitter water", xocolātl referred to the cold, frothy cacao drink consumed by the Aztec nobility and used in ritual contexts. It was typically made from ground cacao, water, and spices such as chilli and vanilla, and was valued for its stimulating and ceremonial properties. When Spanish conquistadors encountered it in the 16th century, they brought it back to Europe, where it was sweetened, heated, and gradually transformed into the drinking chocolate — and eventually the solid chocolate — that we know today. The word itself is a reminder that chocolate has always been more than a sweet: it carries centuries of culture, ritual, and meaning.
Y
York - The Chocolate City
York was once famous around the world for some of the earliest developments in industrialised Chocolate thanks to the tastes of the gentry and merchants that visited the city and the craftsmen like Terrys and Rowntree who rapidly evolved from small shop fronts to major factories and house-hold names. It's been our vision to reconnect with and share these stories so that together we can move that legacy forward with more equitable cocoa supply chains.
