Sugar consumed in the U.S. comes from just two sources: sugar cane and sugar beets. Though both produce nearly identical chemical compositions—about 99.95% sucrose—their differences go beyond sweetness. From environmental impact to ethical considerations, understanding the distinctions between these two sources can help consumers make more informed choices.
Types of Sugar
While all refined sugar may look the same, the source of that sweetness can vary widely. Most sugars are derived from either plants or fruits, and each type has its own production method, flavor profile, and environmental impact. Below, we explore two of the most common sources—sugar cane and sugar beets—and a few lesser-known alternatives.
Sugar Cane
Sugar cane is a tall perennial grass primarily grown in tropical and subtropical regions such as Brazil, India, Thailand, and the southern United States. Once harvested, the stalks are crushed to extract juice, which is then clarified, concentrated, and crystallized into raw sugar. The crystals may be further refined depending on intended use. Sugar cane is a major global source of sucrose and forms the basis of many sweeteners. However, some refining methods—especially in non-organic production—may involve animal bone char, raising concerns for vegan consumers.
How It's Made
- Harvesting – Mature sugar cane stalks are cut and transported to processing facilities.
- Juice Extraction – Stalks are crushed to release sugar-rich juice.
- Clarification – Juice is heated and treated with lime to remove impurities.
- Evaporation – The clarified juice is boiled in evaporators to remove water.
- Crystallization – Concentrated syrup is seeded with sugar crystals to promote crystal formation.
- Separation – Centrifuges separate sugar crystals from molasses.
- Refining (Optional) – Raw sugar may be further purified using carbon filtration or bone char.
- Syrups and Crystals – Used widely in beverages, desserts, sauces, and candy production. Cane sugar provides a clean, sweet flavor that dissolves easily in both hot and cold liquids.
- Molasses – A byproduct of cane processing, used in baking, sauces, and fermented products like rum. Molasses adds richness and depth of flavor to dishes like gingerbread and barbecue sauces.
- Raw Sugar and Turbinado – Lightly refined cane sugar varieties like turbinado are popular for topping baked goods and sweetening drinks. They retain more natural flavor and color than fully refined white sugar.
- Bagasse (Cane Fiber) – The fibrous residue left after juice extraction is used as a renewable fuel source or in making paper products. Bagasse is increasingly valued for sustainable packaging solutions.
- Traditional Confections – Sugar cane is used to create regional sweets like panela and jaggery. These unrefined sugars are staples in Latin American and South Asian cuisines.
Common Uses
Sugar Beets
Sugar beets are root vegetables cultivated in cooler climates like Europe, Russia, and parts of North America. To extract sugar, the beets are sliced and soaked in hot water, releasing sucrose. The juice is purified, concentrated, and crystallized without requiring bone char, making beet-derived sugar a preferred vegan option. Though chemically identical to cane sugar, beet sugar sometimes behaves slightly differently in recipes due to minor processing variations.
How It's Made
- Harvesting – Sugar beets are mechanically lifted from the ground and transported to factories.
- Slicing – Beets are washed and sliced into thin strips called cossettes.
- Diffusion – Cossettes are soaked in hot water to extract sugar through osmosis.
- Purification – Juice is treated with lime and carbon dioxide to remove impurities.
- Evaporation – Water is removed from the juice to create a syrup.
- Crystallization – The syrup is boiled and seeded with sugar crystals to promote crystal growth.
- Separation – Crystals are spun in centrifuges and dried. No bone char is used.
“Sugar beets are harvested seasonally, so factories usually operate around the clock, seven days a week, for four to seven months a year."

Common Uses
- Granulated Beet Sugar – Widely used in baking and food manufacturing, it is nearly indistinguishable from cane sugar in taste and sweetness. It’s often chosen for its cost-effectiveness and bone-char-free refinement.
- Beet Molasses – A thick, dark byproduct used in animal feed, fermentation, and even bioethanol production. It’s nutrient-rich and often repurposed for industrial and agricultural applications.
- Fermentation and Biofuels – The sugar content in beets is suitable for producing bioethanol, making sugar beets an important crop in renewable energy. Beet-based ethanol is commonly used in fuel blends in Europe.
- Sugar Alcohols (e.g., Sorbitol) – Sugar beet processing can yield sugar alcohols used in sugar-free gums, mints, and diabetic-friendly products. These compounds provide sweetness without the blood sugar spikes of regular sugar.
Key Differences Between Sugar Cane and Sugar Beets
Though sugar cane and sugar beets both yield nearly identical refined sugar, the plants themselves are vastly different in how and where they grow, how they’re processed, and how they fit into organic or GMO-free diets. Understanding these differences can help consumers choose the type of sugar that aligns best with their values and preferences. The table below outlines the most important distinctions.
| Category | Sugar Cane | Sugar Beets |
|---|---|---|
| Plant Classification | Tropical grass from the Poaceae family; grows in tall, fibrous stalks in warm, moist climates. | Root vegetable from the Beta vulgaris family; thrives in cooler climates. |
| Global Production Share | Approximately 80% of global sugar production. Brazil produces nearly 40% of the world’s supply. | Accounts for about 20% of global sugar production. |
| Growing Regions | Common in tropical countries such as Brazil, India, and Thailand. | Grown in temperate countries like the U.S., Russia, France, and Germany. |
| Environmental Factors | Requires ample sun and moisture; adaptable to various soil types if moist. | Also needs sun and moisture; prefers well-tilled, less saturated soil and does not do well in rocky terrain. |
| Vegan Status | Often processed with bone char unless labeled vegan; only certain types meet vegan standards. | Not processed with bone char; generally considered more compatible with vegan labeling. |
| GMO Status | Mostly non-GMO worldwide, though some experimentation exists. | Nearly all sugar beets grown in the U.S. are genetically modified for herbicide resistance and environmental durability. |
Other Sugar Options
Beyond sugar cane and sugar beets, there’s a wide variety of natural sweeteners available to consumers. These options are often less processed, offer unique flavors, or serve specific dietary needs. Here are several popular alternatives to traditional refined sugars.
Brown Rice Syrup
Brown rice syrup, crafted from brown rice, is vegan and gluten-free. However, it offers fewer health benefits than one might expect. But then again, this holds for most sugars and sweeteners.
Agave Nectar
A widely used sweetener, agave nectar is an outstanding substitute for refined sugars. Its vegan credentials are impeccable—it originates directly from the agave plant with minimal processing. For vegans who crave sweetness, it's an ideal choice.
Maple Sugar
Maple sugar is created by boiling maple syrup until all the liquid evaporates, leaving behind crystalline sugar. It has a distinct, caramel-like flavor and is often used in specialty baking or as a unique topping for cereals, oatmeal, and desserts. It’s a natural, plant-based alternative that appeals to those avoiding overly refined sweeteners.
Coconut Sugar
Increasingly popular, coconut sugar is a vegan-friendly alternative. Unlike some sugars processed with bone char, coconut sugar avoids this practice. Derived from coconut palm sap, it undergoes minimal refining. Many vegans prefer coconut sugar and its counterpart, beet sugar, with confidence in their vegan status.
Date Sugar
Made from dried, ground dates, date sugar is a minimally processed sweetener that retains some of the fiber, vitamins, and minerals of the whole fruit. It doesn’t dissolve well in liquids but works beautifully in baked goods and energy bars. Because it's made from whole fruit, it's often favored in whole-food-based diets.
