Sugar Cubes: What They Are, How They Are Made, and Portion Perception
Author: Ukrainian Psychological Hub · Published: September 29, 2026 · Editorial Policy
A sugar cube is granulated sugar formed into a small solid unit, usually for sweetening tea, coffee, and other drinks. Most ordinary white sugar cubes are still the same basic ingredient as granulated sugar: crystalline sucrose. The cube changes the physical form, handling, and visual portioning of sugar; it does not create a new kind of carbohydrate.
That simple distinction answers the core question. Sugar cubes are convenient because they turn loose crystals into countable pieces. A person can add one cube, taste the drink, then decide whether to add another. The number of cubes is easy to see and remember. At the same time, cubes are not globally standardized: their size, mass, density, shape, ingredients, and serving definition can differ by manufacturer. A cube is therefore a useful physical unit, not a universal nutrition unit.
This article explains what sugar cubes contain, how they are manufactured, how they compare with loose sugar, how many grams and calories a cube may contain, why package labels matter, how cubes dissolve, how white and brown cubes differ, and what psychology research can actually tell us about discrete portions, visual units, color, shape, expectation, and perceived quality.
What is a sugar cube?
A sugar cube is a compact piece of sugar made by binding many individual sugar crystals into one small solid form. In American food use, the default version is usually made from refined white granulated sugar. Some products instead use brown, demerara-style, raw-style, organic, flavored, colored, or specialty sugars, so the ingredient list remains the final source of truth for a particular product.
For ordinary white cubes, the chemistry is straightforward. The dominant substance is sucrose, the same disaccharide found in table sugar. PubChem identifies sucrose as C12H22O11 and describes it as a nonreducing disaccharide composed of glucose and fructose units. Compressing sucrose crystals into a cube changes their arrangement and the cube's physical structure; it does not turn sucrose into a different sugar.
The word cube is also somewhat conventional. Many commercial pieces are cuboid rather than geometrically perfect cubes, and decorative products can be molded into rectangles, rough-cut lumps, hearts, flowers, or other shapes. The defining idea is a discrete solid portion of sugar, not mathematical geometry.
What are sugar cubes made of?
Classic white sugar cubes are made primarily from granulated sucrose. During production, a small amount of water is introduced so neighboring crystals can bind when the sugar is pressed or molded. The formed pieces are then dried until they are stable enough to package and handle.
That means the finished cube is not best understood as sugar dissolved into a candy-like matrix. It is a porous compact of crystals. The porosity is important: the cube must be strong enough to survive packing and transport but weak and porous enough to break apart and dissolve when liquid penetrates it.
A modern industrial description can be seen in a European patent on sugar-cube drying. The patent describes sugar and water being pressed to the desired shape, size, and weight and then dried to reduce moisture and obtain the required hardness. The patent record illustrates why moisture, pressure, and drying are manufacturing variables rather than nutritional distinctions.
Specialty cubes can contain more than sucrose. A brown cube may retain or include molasses components; decorative cubes may use colors or flavors; some products may include processing aids. These variations should not be generalized from the phrase sugar cube alone. Read the ingredient statement for the actual package.
How are sugar cubes made?
Industrial methods vary, but the basic logic is remarkably consistent: prepare sugar with controlled moisture, form it under pressure or in molds, dry it, cool it, and package it. Historical and modern processes differ in machinery and throughput, yet they solve the same physical problem—how to make separate crystals hold together as a stable piece without melting the sugar into a continuous candy mass.
1. Granulated sugar is prepared
Manufacturers begin with sugar of an appropriate crystal size and quality. For white cubes, this is typically refined granulated sucrose. Crystal-size distribution matters because particles must pack closely enough to form a coherent unit while preserving enough pore space for liquid to enter later.
If you want the larger production story before the cube-making stage, the English Hub article How Sugar Is Made: From Plant to Crystal covers extraction, clarification, concentration, crystallization, separation, drying, and the route from sugar cane or sugar beets to crystalline sugar.
2. The sugar is lightly moistened
A controlled amount of water or steam makes the surfaces of sugar crystals slightly tacky and enables contacts between crystals to consolidate during forming. Too little moisture makes a fragile piece; too much can begin dissolving excessive sugar, distort the structure, lengthen drying, or create unwanted hardness and surface effects.
This is one reason home instructions such as 'add a few drops of water and press sugar into a mold' capture the principle but not industrial process control. Commercial production manages moisture, particle size, pressure, temperature, and residence time much more precisely.
3. The moist sugar is pressed or molded
The prepared sugar is portioned into cavities or formed by a press. Pressure brings crystals into close contact and defines the piece's geometry and density. The cube can then be released to a belt, tray, or other drying system.
The history of this approach goes back to nineteenth-century Dačice. The official City of Dačice account describes Jakub Kryštof Rad's early machine, in which sugar was filled into square openings, compressed by a press, pushed out, and dried. The German Patent and Trade Mark Office likewise describes Rad filling molds with moistened sugar mass, pressing it, and letting it dry; Rad received an imperial privilege for the process in 1843.
4. The formed cubes are dried and hardened
Drying removes the added moisture and stabilizes the contacts between crystals. Modern processes can use heated air, infrared, dielectric, or other controlled drying technologies. The final target is a piece that is mechanically strong enough for distribution but still dissolves readily when exposed to a beverage.
Density and drying also influence how a cube behaves in liquid. A compact piece exposes less immediate surface area than the same mass of loose crystals spread through a drink. Liquid first penetrates the cube, dissolves crystals at accessible surfaces, weakens the structure, and increases surface area as the piece breaks apart. Stirring, beverage temperature, cube porosity, cube size, and sugar mass all affect the practical dissolution time.
Sugar cubes vs granulated sugar: what is actually different?
If a white sugar cube is made only from ordinary granulated sucrose, the fundamental nutritional ingredient is the same as loose white granulated sugar. The meaningful differences are physical form and use: a cube is preformed, countable, portable, visually salient, and slower to disperse initially; loose granulated sugar is free-flowing, easier to measure continuously by weight or volume, and offers more exposed surface area as soon as it is stirred into liquid.
The two forms can therefore produce the same final sweetness when the same mass of sucrose is fully dissolved in the same beverage. What changes during use is the path to that concentration. With loose sugar, many crystals disperse quickly. With a cube, the drink may taste less uniformly sweet for a short period until the cube has broken down or been stirred thoroughly.
This is why 'cube sugar is stronger' or 'granulated sugar is sweeter' is usually the wrong comparison. For the same sucrose mass and final concentration, the chemical sweetener is the same. Differences people notice can come from mass, dissolution stage, beverage temperature, stirring, aroma, bitterness, expectation, or a different sugar type rather than from the cube shape itself.
Sanding sugar is a different physical-form intent: it uses visible crystals as a decorative surface ingredient rather than compressing sucrose into a countable cube. For the dedicated decorating-sugar guide, see Sanding Sugar: What It Is, Texture, Colors, and Uses.
How much sugar is in one sugar cube?
There is no universal gram value for one sugar cube. Commercial pieces vary by country, brand, style, and intended use. Some are small, tightly packed cubes; others are larger rough-cut lumps or specialty shapes. This is the most important correction to the common online shortcut that treats every cube as exactly four grams.
For practical counting, use the package's serving information. If a label states that a serving of two cubes weighs 5 grams, each cube represents about 2.5 grams for that product. If another label states that one cube weighs 4 grams, that product's cube represents 4 grams. The arithmetic is simple: grams per serving divided by cubes per serving equals grams per cube.
A teaspoon is also an approximate household comparison rather than a definition of a cube. MedlinePlus notes that 4 grams of table sugar provide about 16 calories and are roughly one teaspoon, but a particular manufactured cube can weigh more or less than that. Grams are more reliable than assuming 'one cube equals one teaspoon.'
How many calories are in a sugar cube?
Calories depend on the cube's mass, not on the fact that the sugar has been shaped into a cube. Traditional sugars are commonly calculated at about 4 calories per gram. A 4-gram cube would therefore provide about 16 calories; a 2.5-gram cube would provide about 10 calories. These are calculations, not universal cube specifications.
For a package in front of you, use its Nutrition Facts label rather than an internet average. For the broader calorie lookup intent, see Sugar Calories: How Many Calories Are in Sugar?. For label categories, carbohydrate, Total Sugars, and Added Sugars, see Sugar Nutrition Facts: Calories, Carbohydrates, and Added Sugars.
Does a sugar cube count as added sugar?
In the United States, ordinary table sugar used as a sweetener falls within the FDA's Added Sugars framework. The FDA's Added Sugars guidance says Added Sugars include sugars added during processing, foods packaged as sweeteners such as table sugar, sugars from syrups and honey, and certain concentrated fruit or vegetable juices. The Daily Value for Added Sugars is 50 grams on a 2,000-calorie diet.
That FDA category is not the same term as the World Health Organization's free sugars. WHO's guideline on sugars intake uses free sugars for monosaccharides and disaccharides added by the manufacturer, cook, or consumer, plus sugars naturally present in honey, syrups, fruit juices, and fruit-juice concentrates. When you drop a sucrose cube into coffee or tea, it is a consumer-added sweetener and fits the practical logic of both frameworks, even though the formal definitions were developed for different regulatory and public-health purposes.
This article does not convert cubes into a personalized daily allowance. A cube's weight is not standardized, individual energy needs differ, and 'serving size' is not a prescription. The FDA explicitly states that serving size on the Nutrition Facts label is not a recommendation of how much a person should eat or drink.
Why sugar cubes are psychologically different from loose sugar
The chemistry can be identical while the decision environment is different. Loose sugar is continuous: a person pours or spoons an amount that may be visually hard to track, especially across repeated additions. Cubes discretize the same ingredient into countable objects. That changes what can be perceived, remembered, compared, and communicated.
A cube creates a visible action boundary. 'One more cube' is a distinct choice, whereas 'a little more sugar' can be an imprecise movement of a spoon or dispenser. This does not guarantee lower intake. It does, however, make the amount easier to count, and countable units can become psychological reference points.
Unit bias: one object can feel like one appropriate amount
A classic study by Geier, Rozin, and Doros proposed the idea of unit bias: people may treat a single offered unit as an appropriate amount and consume more when the available unit is larger. Their experiments found greater intake when foods were offered in larger rather than smaller units or with a larger serving spoon.
The idea is relevant to sugar cubes because a cube is literally a designed unit. Yet the evidence should not be overextended. The Geier study did not test sugar cubes, and it does not show that one cube is a biologically appropriate serving of sugar. It shows that the boundaries built into foods and serving tools can influence choice.
Segmentation may matter more than a strict 'one unit' rule
Later work complicated the simple unit-bias story. In two experiments, Kerameas and colleagues found that people given multiple smaller units ate less than people given a single larger unit of the same total portion, but they did not generally stop after exactly one unit. The authors argued that a segmentation effect better described the findings: dividing food into visible subunits can change perceived norms and intake without turning one unit into an automatic stopping rule.
For sugar cubes, this suggests a practical interpretation. Discrete units can make increments salient—zero, one, two, three—yet the number chosen still depends on cup size, prior habit, desired sweetness, social context, taste, and the size of the cubes themselves. Cubes provide segmentation; they do not provide a built-in health target.
The broader portion-size evidence
A large Cochrane systematic review found that people generally consumed more food or nonalcoholic drink when exposed to larger portions, packages, individual units, or tableware than when exposed to smaller-sized versions. That supports the broader claim that physical presentation can influence selection and consumption.
Again, the evidence is about portion environments in general, not a clinical intervention based on sugar cubes. It is reasonable to say that cube size and count can function as portion cues. It is not justified to claim that switching from loose sugar to cubes will reliably reduce sugar intake for every person.
Why cubes can make sugar quantity easier to visualize
Humans do not perceive food quantity from grams alone. We use number, size, occupied area, package form, container dimensions, and familiar objects as visual evidence. A review of visual cues and food consumption identified portion size, number, shape, volume, surface area, color, visibility, and other visual properties as cues that can influence food acceptance, perceived quantity, or consumption.
Sugar cubes exploit this naturally. Four cubes are visually four objects. Four grams of dissolved sugar in a drink are visually absent. This is why public-health graphics sometimes use cubes to represent the sugar content of beverages or foods: the cube turns an invisible mass into a familiar count.
That visualization has a limitation. The metaphor becomes misleading when the graphic silently assumes one fixed cube weight. If a campaign uses 4-gram cubes but a viewer's household cubes are 2.5 grams, the object count is not interchangeable. Good communication states the gram-to-cube conversion used in the illustration.
Why a sugar cube can feel more precise than it really is
Discrete objects create a strong sense of exactness. One cube looks categorical: it is either present or absent. A spoonful looks less exact because the surface can be heaped, level, rounded, or partial. This can make cubes feel like a more precise dosing system.
The precision is real within a single standardized product lot if individual pieces are manufactured to a consistent target. It is false when generalized across brands. 'Two cubes' is exact as a count but incomplete as a mass. Nutrition is measured in grams, and different cubes can assign different grams to the same count.
The most reliable way to use cubes for tracking is therefore label-based: identify grams per serving, identify cubes per serving, calculate grams per cube, and use that product-specific value. The cube can then become a convenient counting device without pretending that the entire category has one standard size.
Color, shape, texture, and sweetness expectation
Sugar cubes also have a sensory-psychology layer because people see and handle them before they dissolve. White color can signal refinement and cleanliness in one context; beige or brown color can signal less processing, molasses, tradition, or naturalness in another. A rough irregular cube can suggest craft or premium production, whereas a sharply regular white cube can suggest uniformity and precision. These are expectations about the product, not direct measurements of its nutritional value.
Visual cues can influence expected and sometimes perceived sweetness
A review by Wang and colleagues describes evidence that intrinsic factors such as food color, aroma, texture, and viscosity, along with extrinsic factors such as packaging and servingware, can influence sweetness perception. A newer systematic review by Motoki, Spence, and Velasco concluded that visual cues such as color and shape affect taste or flavor perception in some studies, while other studies find mixed, limited, or null effects.
That mixed evidence matters. It would be too strong to say that a cube's white color or angular geometry reliably changes the sweetness of dissolved sucrose. Once the cube disappears into a beverage, actual sucrose concentration, temperature, aroma, bitterness, acidity, and the drink's composition remain major determinants of the sensory experience. Visual form is one cue in a multisensory system.
For the dedicated explanation of color–sweetness correspondences, expectation, and the limits of visual sweetness effects, see Color and Sweetness: How Appearance Changes Taste Expectation.
A cube's angular shape does not make sucrose chemically less sweet
Research on crossmodal correspondences often finds associations between roundness and sweetness and between angularity and bitter or sour qualities. Those associations concern expectation and sensory matching. They do not mean a square sugar cube contains weaker sucrose or that molding the same crystals into a sphere would increase their intrinsic sweetness.
For a familiar object labeled and recognized as sugar, learned identity can dominate an abstract shape association. This is a useful example of why sensory psychology must distinguish a cue from the chemical stimulus it helps us interpret.
Brown or 'natural-looking' cubes can carry a naturalness halo
Color and texture also communicate provenance. A brown, rough-cut, or less uniform sugar piece can look less processed than a white machine-regular cube. A systematic review by Román, Sánchez-Siles, and Siegrist found that perceived food naturalness is important to consumers and is shaped by ideas about origin, production, and the final product.
Naturalness perception is a consumer judgment, not a nutrient analysis. A brown cube may genuinely differ in molasses content, flavor, moisture, or processing history, but the appearance alone does not establish that it is meaningfully lower in sugar, lower in calories, or better for health. The ingredient statement and Nutrition Facts label answer those questions more reliably than color.
White sugar cubes, brown sugar cubes, and specialty cubes
White sugar cubes are usually compacted refined white sugar. Their sensory profile is dominated by sucrose sweetness, with little aroma. They are visually neutral and common in formal tea or coffee service.
Brown sugar cubes can be made from sugar that contains or is coated with molasses components. They may contribute caramel, toffee, mineral, or molasses-associated aromas in addition to sweetness. Their moisture, density, and dissolution behavior can differ from white cubes depending on formulation.
Demerara-style or raw-style cubes are often coarser, golden or brown, and deliberately irregular. Their appearance can carry strong expectations of craftsmanship, provenance, or naturalness. Those expectations may enhance perceived quality or fit a particular ritual, but they should not be translated automatically into a health advantage.
Flavored, colored, embossed, or decorative cubes belong to the same broad form category but can include additional ingredients. When a cube contains colors, extracts, spices, herbs, or other components, its flavor and nutrition should be evaluated as that product rather than inferred from plain sucrose cubes.
How sugar cubes dissolve in coffee and tea
Dissolution begins where liquid contacts exposed sugar crystals. Hotter liquid generally speeds molecular movement and dissolution, while stirring brings unsaturated liquid into contact with the cube and carries dissolved sugar away from the surface. As the structural contacts weaken, fragments separate and the effective surface area rises.
This creates a brief sensory sequence that loose sugar may not produce as strongly. The first sip after dropping in a cube can be less sweet than a later sip if the cube has not fully dissolved or the drink is not mixed. A person may interpret that early sip as evidence that more sugar is needed, add another cube, and then discover that the final drink is sweeter than intended once everything dissolves.
A practical way to avoid that mismatch is simple: let the cube dissolve and stir before evaluating sweetness. This is not a dietary rule; it is a sensory-control rule. It separates the decision 'How sweet do I want this beverage?' from the temporary physical fact that part of the sweetener is still sitting at the bottom of the cup.
Common uses of sugar cubes
The classic use is tabletop sweetening for hot beverages. Cubes are clean to handle, easy to count, visually tidy, and convenient in hospitality settings. They also fit ceremonial or traditional serving styles because the object itself can be presented in a bowl, lifted with tongs, and added deliberately.
Cubes can be used in cocktails and other preparations where gradual dissolution, muddling, or presentation matters. In cooking, they can sweeten a liquid if they are dissolved, but loose granulated sugar is usually more practical for recipes that require accurate gram weights, rapid dispersion, creaming, sprinkling, or even distribution through dry ingredients.
They are also used as visual teaching objects because their regular form makes quantity tangible. That educational value is strongest when the cube's assumed mass is stated. A display of ten 4-gram reference cubes represents 40 grams of sugar; ten arbitrary household cubes do not necessarily represent the same mass.
Are sugar cubes healthier than loose sugar?
Not inherently. If a cube and loose granulated sugar contain the same sucrose and you consume the same mass, the cube shape does not create a nutritional advantage. The cube can change how the amount is presented and counted, which may be useful for awareness, but the biological exposure still depends on how much sugar is consumed.
The strongest evidence-based distinction is therefore between form and amount. Form affects convenience, visual segmentation, expectation, and dissolution. Amount determines the grams of sugar contributed by the sweetener. Broader dietary context determines how those grams fit with the rest of the diet.
This is also why 'portion control' should be phrased carefully. Cubes can support portion awareness because the units are visible and countable. Research on portion size and segmentation makes that psychologically plausible. Evidence does not establish sugar cubes themselves as a proven weight-management or sugar-reduction intervention.
Sugar cubes and portion perception: established evidence, plausible interpretation, and limits
Established evidence: portion and unit size can influence how much people select or consume in experimental settings; visual cues such as number, size, and portion boundaries can affect quantity judgments; food form and appearance can shape sensory expectations. These findings are supported by controlled studies and systematic reviews.
Plausible interpretation: because sugar cubes transform a loose ingredient into visible discrete units, they can make additions easier to count and may create clearer stopping points than an unmeasured pour. This follows from general research on segmentation and visual portion cues.
Not established: there is no basis for treating one sugar cube as the psychologically or biologically 'correct' serving, and the research cited here does not show that switching from loose sugar to cubes reliably reduces added-sugar intake, improves weight, changes blood glucose control, or prevents disease.
The boundary matters because a familiar object can easily acquire more authority than the evidence supports. A cube is a useful unit of presentation. It is not a clinical dose, a universal serving standard, or a therapeutic tool.
Practical ways to use sugar cubes accurately
First, check the label once. Find the serving mass in grams and the number of cubes in that serving. Divide grams by cubes. You now know the approximate mass of one cube for that product.
Second, treat that result as product-specific. If you change brands, cube styles, or countries, check again. Large rough-cut pieces and small pressed cubes can differ materially in mass even though both are called sugar cubes.
Third, if you are comparing cubes with spooned sugar, compare grams rather than visual volume. A teaspoon is a household volume measure; a cube is a manufactured object; a gram is a mass measure. Grams make the comparison transportable across shapes.
Fourth, let a cube dissolve before deciding whether a drink needs another one. This reduces the chance that incomplete mixing is mistaken for insufficient sweetness.
Fifth, remember the labeling distinction. A package's serving size describes the amount used for nutrition labeling and is not an individualized recommendation. For health guidance, use relevant public-health advice rather than converting the word serving into a target.
A brief history of the sugar cube
Before modern granulated sugar became the familiar household form, refined sugar was commonly sold in hard loaves that had to be broken into pieces. That made standardized small portions mechanically useful as well as convenient.
Dačice, now in the Czech Republic, is closely associated with the invention of the modern pressed cube. The city's official history credits Jakub Kryštof Rad with developing the first sugar-cube production process and receiving an imperial privilege in 1843. The historical machine compressed sugar in square openings and dried the formed pieces.
The invention solved a mundane but important interface problem: sugar was already desirable, but the available physical form was awkward. The cube redesigned the interaction between person and ingredient. That design logic still explains its appeal today—clean handling, countability, repeatable presentation, and an obvious unit boundary.
Common myths about sugar cubes
Myth: every sugar cube weighs 4 grams
A 4-gram cube is a useful example, not a universal standard. Cube mass varies. Use the product label when the exact amount matters.
Myth: one cube always equals one teaspoon
One teaspoon of granulated table sugar is commonly approximated at about 4 grams, but manufactured cubes can be smaller or larger. A cube count and a teaspoon volume are not interchangeable by definition.
Myth: cubes are healthier because they are portion controlled
A cube can make portions countable, but shape does not reduce the calories or added-sugar content of a given mass of sucrose. Behavioral effects depend on how the units are actually used.
Myth: brown cubes are automatically healthier than white cubes
Brown color can reflect molasses or a different processing style, and it can alter flavor. Appearance alone does not establish a meaningful health advantage. Compare ingredients and nutrition information.
Myth: sugar cubes dissolve into a different kind of sugar
Plain white cubes remain sucrose before and after dissolution. Dissolving disperses sucrose molecules through the liquid; it does not convert the cube into a different dietary sugar merely because the solid shape disappears.
Myth: cube counting tells you whether your total diet is healthy
Cube counting can describe one added sweetener. It does not capture sugars in other foods and drinks, overall energy intake, dietary pattern, dental exposure, nutrient density, or individual health needs. It is one measurement aid, not a complete dietary assessment.
Frequently asked questions
What is a sugar cube in one sentence?
A sugar cube is a small solid portion of sugar, usually granulated sucrose that has been lightly moistened, pressed or molded, and dried.
Are sugar cubes the same as regular sugar?
Plain white sugar cubes are generally the same basic sucrose ingredient as regular white granulated sugar; the main difference is that the crystals have been formed into a discrete solid unit.
How are sugar cubes held together?
Controlled moisture and pressure bring sugar crystals into close contact during forming, and drying stabilizes those contacts so the piece can be handled while remaining porous enough to dissolve.
How much does one sugar cube weigh?
There is no universal weight. Check the package's grams per serving and cubes per serving, then divide to estimate grams per cube for that product.
How many calories are in one sugar cube?
The answer depends on cube mass. Traditional sugar contributes about 4 calories per gram, so a 4-gram cube is about 16 calories and a 2.5-gram cube about 10 calories. Use the package label for the product you actually have.
Is one sugar cube one serving?
Not necessarily. The serving size is defined on the product's Nutrition Facts label, and the FDA emphasizes that serving size is not a recommendation of how much to consume.
Are sugar cubes good for portion control?
They can make sugar additions visible and countable, which supports portion awareness. Research on unit size, segmentation, and portion cues shows that presentation can influence behavior, but sugar cubes themselves are not established as a guaranteed sugar-reduction intervention.
Why do sugar cubes dissolve more slowly than loose sugar?
A compact cube initially exposes less surface area to the liquid than the same mass of dispersed loose crystals. As liquid penetrates the cube and it breaks apart, surface area increases and dissolution accelerates.
Are brown sugar cubes different from white sugar cubes?
They can be. Brown cubes may contain molasses components and can differ in aroma, flavor, moisture, color, density, and processing. Check the ingredient list because products marketed as brown or raw-style cubes are not all formulated the same way.
Why are sugar cubes often used to visualize sugar content?
Cubes turn an invisible gram quantity into countable objects. The visualization is intuitive, but it is accurate only when the graphic states or consistently uses a defined grams-per-cube conversion.
Sugar cubes can make quantity easier to visualize, but dietary guidance is defined in grams, percentages, meals, and sugar categories rather than in a universal number of cubes. For current intake guidance, see How Much Sugar Per Day? Guidelines, Labels, and Practical Context.
