The Simple Answer: They Are the Same
For most home cooks and bakers, the terms "granulated sugar" and "white sugar" are completely interchangeable and refer to the exact same product. The standard, all-purpose sugar you find in your grocery store's baking aisle is granulated white sugar. Think of "white sugar" as the general category, and "granulated" as the most prominent member of that category, defined by its specific crystal size. This is also why you will see it labeled as "granulated," "white," or "table" sugar, all of which mean the same thing.
Why the Different Names?
White sugar is a broad term that describes any sugar that has had its natural molasses stripped away during the refining process, leaving behind pure sucrose. Granulated sugar, therefore, is a type of white sugar that has been crystallized into a medium, uniform grain. The key takeaway is that when a recipe calls for white sugar, it means granulated sugar, unless a different type of white sugar (like powdered or superfine) is specifically mentioned.
The Manufacturing Process
The journey of sugar from a plant to a white crystalline product is a testament to food science. The process removes all impurities and natural molasses to create the pure sucrose we recognize as white sugar.
From Plant to Pantry
- Harvesting and Extraction: Sugarcane stalks or sugar beets are harvested and transported to a processing plant. The sweet juice containing the sucrose is then extracted through crushing or diffusion.
- Purification and Clarification: The extracted juice is heated and treated with agents like lime to clarify it, removing non-sugar impurities. This results in a cleaner, clearer juice.
- Evaporation: The purified juice is boiled in a multi-stage process to evaporate most of the water, concentrating the syrup.
- Crystallization: The concentrated syrup is boiled further under a vacuum, and tiny seed crystals are introduced. This allows the sucrose to form crystals in a controlled manner.
- Centrifugal Separation: The mixture of sugar crystals and residual syrup (molasses) is spun in a centrifuge. The force separates the crystals from the molasses, resulting in a raw, crystalline sugar.
- Refining and Finishing: The raw sugar is further refined and filtered, often with carbon, to remove any remaining color and impurities, making it pristinely white. It is then dried, sifted to a uniform size (granulation), and packaged.
A Closer Look at "White Sugar" Variations
While granulated is the most common form, the broader "white sugar" category includes several other types defined by their crystal size. These are not the same as granulated sugar and have different culinary uses.
- Superfine or Caster Sugar: This white sugar is ground to a smaller, finer crystal than granulated. Its tiny size allows it to dissolve more quickly, making it perfect for meringues, delicate cakes, and sweetening cold beverages.
- Confectioners' or Powdered Sugar: This is granulated sugar that has been ground into a very fine, soft powder. It typically contains a small amount of cornstarch to prevent clumping. Powdered sugar is essential for icings, frostings, and dusting baked goods.
- Coarse or Sanding Sugar: The opposite of superfine, this sugar has large, sparkling crystals that are resistant to heat. It is used primarily for decoration on cookies, pastries, and other baked goods to add texture and a crystalline sparkle.
Common Uses in the Kitchen
Because granulated white sugar is the versatile workhorse of the pantry, it's used in countless applications across cooking and baking. A few of its many uses include:
- Sweetening coffee, tea, and other hot or cold beverages.
- Used in almost all standard cake, cookie, and brownie recipes.
- Creating caramel sauce by melting the sugar crystals.
- Balancing acidity in savory dishes and sauces.
- Actively aiding in the browning and tenderization of baked goods.
Granulated vs. Other Sugar Types: A Comparison
To highlight the differences between the various forms of white sugar, here is a simple comparison table:
| Feature | Granulated Sugar | Superfine (Caster) Sugar | Powdered (Confectioners') Sugar |
|---|---|---|---|
| Crystal Size | Medium and uniform, like table salt. | Very fine, smaller than granulated. | Ground to a very fine powder. |
| Best For | General baking, cooking, and sweetening. | Delicate baked goods, meringues, and quick-dissolving liquids. | Frostings, icings, glazes, and dusting. |
| Dissolvability | Dissolves readily, but can be grainy if not mixed well. | Dissolves very quickly and smoothly. | Dissolves almost instantly in liquids. |
| Texture | Standard granular texture. | Smooth texture due to fine crystals. | Silky, powdery texture. |
Conclusion
To put it simply, yes, granulated sugar and white sugar are the same thing. The term "white sugar" serves as a broad classification for refined sugars, while "granulated" specifies the most common, medium-sized crystal form that is a staple in most kitchens. Understanding this relationship helps clarify recipe instructions and explains why you can confidently use a bag labeled "granulated sugar" for any recipe that calls for "white sugar." The key is to pay attention to any further specifications regarding particle size, such as "superfine" or "powdered," which indicate a different type of white sugar altogether.

Frequently Asked Questions
What if a recipe just says "sugar"? What should I use?
If a recipe simply calls for "sugar," it is safe to assume it means standard granulated white sugar, as it is the most common all-purpose sugar used in baking and cooking.
Can I substitute cane sugar for granulated sugar?
Yes, you can substitute cane sugar for granulated sugar on a 1:1 basis, as both are sucrose. However, cane sugar is made exclusively from sugarcane and is less refined, so it has slightly larger crystals and a hint of molasses flavor that may slightly alter the texture and taste.
Is brown sugar a type of white sugar?
No, brown sugar is not a type of white sugar. Brown sugar is made by either retaining some of the natural molasses during processing or adding molasses back into refined white sugar. This gives it its color, moisture, and distinct flavor.
What is the difference between table sugar and granulated sugar?
There is no difference; the terms "table sugar" and "granulated sugar" both refer to the same standard white sugar with a medium-sized crystal.
How do I store granulated sugar to keep it fresh?
Store granulated sugar in an airtight container in a cool, dry place. This prevents moisture from causing it to clump and keeps it fresh indefinitely.
Why does caster sugar dissolve faster than granulated sugar?
Caster sugar dissolves faster than granulated sugar because its crystals are much finer. The smaller surface area allows for quicker dissolution, which is beneficial for recipes like meringues and cocktails.
Can I make powdered sugar from granulated sugar?
Yes, you can make powdered sugar at home by grinding granulated sugar in a blender, food processor, or clean coffee grinder. Adding a small amount of cornstarch can help prevent caking.
