Stevia is the common name of the plant Stevia rebaudiana, and the word is also used for sweeteners made with steviol glycosides. At the supermarket, however, two products labelled “stevia” can contain different ingredients and need different serving amounts. Understanding the difference between a concentrated sweetening ingredient and a finished blend helps you choose a product and use it correctly.
What gives stevia its sweetness?
Steviol glycosides are intensely sweet compounds. Food Standards Australia New Zealand (FSANZ) describes them as around 150–300 times sweeter than sugar. They are usually made from stevia leaves, although approved production methods also include enzymatic conversion and fermentation.
That sweetness range describes the concentrated ingredient. It does not tell you how many teaspoons of a particular retail product to use. A spoonable blend may have a much lower sweetness concentration because it combines the intense sweetener with other ingredients.
Stevia leaf, concentrated extract and sweetener blend
| Term | What it describes | What to check |
|---|---|---|
| Stevia leaf | Leaves of the stevia plant. | Leaf material is different from a purified sweetening ingredient or a formulated tabletop product. |
| Concentrated stevia extract | A concentrated source of steviol glycosides. | Use the supplier’s directions. A recipe written for a spoonable blend cannot be assumed to work with the same quantity of extract. |
| Stevia sweetener blend | A finished formulation containing steviol glycosides alongside other ingredients. | Read the complete ingredient list and the sweetness guide for that specific product. |
Words such as “powder”, “granules” and “liquid” describe a product’s form. They do not establish its concentration. Two powders can have very different strengths; two liquid sweeteners can use different sweetening ingredients altogether.
Why do some stevia products contain other ingredients?
An intense sweetener provides sweetness in a small amount. A finished blend can make that sweetness easier to measure for everyday use. The formulation determines how much to add and how the product behaves, so the other ingredients matter as well as the intense sweetening component.
Erythritol appearing on a stevia product’s ingredient list is therefore useful information about the blend. It is a separate ingredient from steviol glycosides. Check the whole list when comparing products, especially if you are looking for, or avoiding, a particular ingredient.
How to read a stevia sweetener label
- Start with the ingredients. FSANZ explains that ingredients are listed by ingoing weight, from greatest to least. This helps you understand the formulation, although the list alone does not give an exact percentage for every ingredient.
- Find the serving directions. Look for the stated amount and its sweetness equivalent. Keep teaspoons, grams, sticks, tablets and drops distinct; a direction in one unit is not automatically a direction in another.
- Read the nutrition information for the finished product. Use the stated serving size when considering the amount you will actually use. The name “stevia” alone does not establish a blend’s energy or nutrient content.
- Check the practical details. Consider pack size, storage instructions and whether the format suits your kitchen, desk or bag.
FSANZ’s nutrition-panel guide explains the difference between per-serving and per-100g information. A common weight basis helps compare similar products, but different sweetener strengths can mean different amounts are needed for the same use.
A product-specific example: the Sugarless canister
The Sugarless Organic Stevia Sweetener 350g canister contains organic erythritol and organic steviol glycosides. It is a spoonable blend. Its serving guide is ½ teaspoon (2g) for the sweetness of one level teaspoon of sugar, with 175 serves per canister and 0.5 calories per serve.
Those directions belong to this product. They should not be transferred to another brand, a concentrated extract or a different format. For larger quantities and measurement guidance, use our sugar-to-stevia conversion guide.
Choosing a format for everyday use
For drinks: a spoonable product lets you measure an amount, while individual sticks or tablets can be convenient when you want a portion to take with you. Start with the directions on your pack and adjust the amount to suit your taste.
For recipes: choose the exact sweetener named in the recipe wherever possible. A format that is convenient for a cup of tea is not necessarily the appropriate ingredient for a cake.
For shared kitchens: consider how the product will be stored and portioned. When comparing value, check both pack size and stated servings. Comparing cost per serve is most useful when the servings provide a comparable amount of sweetness.

Sweetness conversion is only one part of baking
Sugar contributes more than sweetness to a recipe. It also affects volume, moisture, texture and browning. Matching sweetness with a different ingredient does not reproduce all those functions.
A useful starting approach is to follow a recipe designed for your blend, measure carefully and assess the finished result. Keep a note of the product, amount and method if you make adjustments. Changing several ingredients at once makes it harder to understand which change affected the outcome.
Our baking guide explains these considerations in more detail. Browse our recipes for ideas, and check the named sweetener before starting. The sugar content of a finished dish depends on all its ingredients.
Choose the product, then follow its directions
The most useful comparison starts with what you want to make. Identify the format and ingredients, check the product’s own serving guide, and choose a recipe suited to it when cooking. This turns the broad word “stevia” into a practical decision about the sweetener you will actually use.
Comparing stevia with monk fruit?
Start with our monk fruit guide to understand the fruit, concentrated extract and finished blends, then use the stevia and monk fruit comparison for the Sugarless products. If you already know which format you need, browse the Organic Stevia range or see the 350g stevia sweetener canister for ingredients, serving amounts and current pack options.
