Decoding the Sweetener Color Code
For many years, the foodservice industry has utilized a color-coded system for single-serving sweetener packets, making it easy for consumers to identify their preferred sugar substitute at a glance. This practice saves time and eliminates confusion, especially for individuals managing conditions like diabetes or adhering to specific dietary plans. The system is widely recognized in North America and includes the following associations:
- Green: Stevia-based sweeteners.
- Yellow: Sucralose, commonly sold under the brand name Splenda.
- Pink: Saccharin, often known by the brand Sweet'N Low.
- Blue: Aspartame, found in products like Equal.
- White: Typically signifies pure, granulated table sugar.
This system provides a simple visual cue for consumers. Therefore, in most coffee shops, restaurants, and grocery stores, if you are looking for stevia, you should reach for the green packet.
Green vs. White Stevia: Understanding the Differences
While the packet is consistently green, the color of the stevia powder itself can be green or white, a distinction that depends on the level of processing and refinement. This difference is crucial for understanding the product's flavor profile, purity, and intended use.
The All-Natural Green Stevia Powder
Green stevia powder is a product of the whole, dried stevia leaf, which is a naturally green plant. After being harvested and dried, the leaves are typically ground into a fine powder. This form is the least processed and retains all the compounds naturally present in the leaf, including the sweet-tasting steviol glycosides as well as other plant materials. The result is a powder that is less intensely sweet than its white counterpart and often carries a distinct, sometimes licorice-like, aftertaste. Because of its unrefined nature, it is not as sweet as table sugar and requires less heat to activate its sweetness.
The Highly Refined White Stevia Extract
In contrast, the more popular white stevia is a highly refined extract. The sweet compounds, or steviol glycosides (primarily Rebaudioside A or Reb A), are isolated and concentrated through a multi-step process. This purification process removes most of the plant matter and compounds that contribute to the green color and aftertaste. What remains is a pure white, crystalline powder that can be hundreds of times sweeter than sugar. Because it is so potent, commercial white stevia products are almost always blended with a bulking agent, such as erythritol, dextrose, or maltodextrin, to make it easier for consumers to measure and use. This refinement allows for a cleaner, more sugar-like sweetness and taste profile, which is why it is used in most commercially available stevia packets.
The Role of Additives in Stevia Products
When you buy a box of single-serving stevia packets, what you're getting is often more than just stevia extract. Due to the potency of the refined white stevia, it must be diluted to be measured easily. A common filler is erythritol, a sugar alcohol that provides bulk and helps reduce the intense aftertaste. Other additives can include dextrose or maltodextrin, which are carbohydrates.
Liquid Stevia and Blends
Stevia is not limited to powder form. It is also sold as a liquid extract or drops. Liquid stevia is generally made by steeping the stevia leaves in water or a food-grade alcohol. The color of liquid stevia can vary, sometimes appearing light yellow or having a slight brown tinge, depending on the extraction method and any added preservatives. Some brands also offer stevia blends that mix the extract with other natural sweeteners, like monk fruit, to further improve the taste profile.
A Comparison of Stevia Types
| Aspect | Green Stevia Powder | White Stevia Extract (Commercial) |
|---|---|---|
| Origin | Whole, dried leaves of the stevia plant. | Isolated and purified steviol glycosides from the leaves. |
| Processing | Minimally processed; leaves are dried and ground. | Highly processed to isolate the sweetest compounds. |
| Appearance | Greenish powder. | Pure white crystalline powder. |
| Flavor Profile | Less sweet than refined versions, with a distinct, sometimes bitter, aftertaste. | Very intense sweetness with a cleaner, more refined taste. |
| Sweetness Level | Much less potent than the extract, closer to sugar in some regards. | 200-400 times sweeter than table sugar. |
| Bulking Agents | None; it is simply ground leaves. | Often blended with fillers like erythritol or maltodextrin for volume and ease of measurement. |
| Best For | Herbal teas, homemade recipes where a natural, earthy flavor is desired. | Coffee, baking, and general sweetening where a clean, potent sweetness is needed. |
Making the Right Choice for Your Needs
Choosing between green and white stevia depends on your personal taste preferences and intended use. If you prioritize the least processed, most natural form and don't mind a milder, slightly earthy or bitter aftertaste, the green whole-leaf powder is the right choice. For those who want a powerful, clean-tasting sweetness that more closely mimics sugar and is convenient for everyday use in coffee, tea, and baking, the highly refined white stevia extract is the better option. Always read the ingredients list to understand what fillers might be included in a commercial product.
Conclusion: Which Color Sweetener is Stevia?
Ultimately, stevia is most commonly associated with the green packet in the standardized sweetener color-coding system. However, the actual sweetener inside can be either a green powder (whole leaf) or a white powder (highly refined extract), with the latter being far more prevalent in commercial packets. The key takeaway is to recognize that the green packaging is a marketing convention for easy identification, while the color of the product itself reflects its level of processing and refinement. By understanding the difference, consumers can make a more informed choice that aligns with their dietary needs and taste preferences.

Key Takeaways
- Green Packet Convention: Stevia is typically packaged in green packets to align with a universal color-coding system for low-calorie sweeteners.
- Whole Leaf is Green: The whole, dried, and ground stevia leaf is naturally green and less potent than the refined extract.
- Refined Extract is White: The highly purified steviol glycosides, which provide the intense sweetness, are a white powder.
- Processing Makes it White: The process of extracting and purifying the sweet compounds removes the chlorophyll and other plant matter, changing its color.
- Commercial Products Vary: The stevia inside a green packet can be a blend of the white extract with bulking agents like erythritol or maltodextrin.
- Taste Profile Varies: The green powder has a more distinct, earthy flavor, while the white extract is cleaner and sweeter.
- Read the Label: Always check the ingredients to understand what other substances, besides pure stevia, are in the packet.
FAQs
Why are some stevia packets green?
Stevia packets are colored green as part of a widely adopted system for color-coding different non-sugar sweeteners, making them easily identifiable to consumers.
Is the actual stevia powder inside the green packet green?
Not usually. The packets almost always contain white, highly refined stevia extract powder that has been blended with other ingredients like erythritol for easier measurement.
What is the difference between green stevia powder and white stevia powder?
Green stevia is made from the whole, ground stevia leaf and is less processed. White stevia is a highly refined extract containing isolated sweet compounds called steviol glycosides.
Does green stevia taste different from white stevia?
Yes, green stevia powder has a milder, more earthy or bitter taste, whereas white stevia extract is intensely sweet with a cleaner flavor profile.
Is one color of stevia healthier than the other?
This is a matter of debate. Green stevia is less processed and a whole-leaf product, which some consider more natural. White stevia extract is highly purified, but the refining process and addition of bulking agents concern some consumers.
Can stevia be used for baking?
Yes, both green and white stevia can be used for baking, though white stevia extract is more common due to its cleaner taste. Since it is much sweeter than sugar, recipes must be adapted carefully.
What do the colors of other sweetener packets mean?
Beyond green for stevia, yellow packets are for sucralose, pink for saccharin, and blue for aspartame.
Why does some liquid stevia have a brownish color?
The slight color in some liquid stevia can be from the natural extraction process, oxidation, or added preservatives like ascorbic acid.
